AMD FX 8350 acceleration on the Maternal Asus. Processors

Overclocking FX-8350 is a fairly simple operation and allows you to significantly increase the speed of the personal computer. The procedure for its implementation will be gradually and is set out in detail later under this review. In addition to this, general recommendations on the configuration of the PC will be given and the technical parameters of the microprocessor will be given.

The list of this CPU includes such components:

1. Chip, packed in protective boxing.
2. Cooling and thermal cooled system.
3. Warranty card and brief user guide.
4. Sticker with the logo of the CPU family.

The first important condition for overclocking PC is its quality equipment. Therefore, with a standard heat sink system, the CPU is better not to accelerate. With advanced air cooler, this chip model is capable of issuing 4.5-4.7 GHz. If you use liquid cooling, then you can count on the conquest of the plank of 5.0-5.2 GHz. That is, on a twenty percent increase in speed of work. The power supply must also have a solid power supply, the minimum value of which should be 800 W. In addition to this, the graphics accelerator must be equipped with an improved cooling system and high-quality semiconductor elements. RAM, in turn, should allow to increase the clock frequency and equipped with radiators for cooling.

The motherboard must be at least ATX format. If for these purposes to apply smaller devices, there may be overheated problems. Therefore, the acceleration of FX-8350 for, for example, it is better not to implement. As experience shows, the computer overheats in this case and can even break. This board has microatx format and is designed to create ultra-compact PCs. But the Overclocking FX-8350 on the Gigabyte GA-970A-DS3P can and should be carried out. She has everything you need for this. As a result, it can be noted that the choice of an improved system board is a guarantee of high-quality overclocking.

CPU specifications

Before the acceleration of FX-8350 will be further discussed in detail in detail, we give the technical specifications. This CPU model is based on the Vishera code name architecture and is intended for installation in the currently outdated processor socket AM3 +. Nominally, this chip includes eight program code processing units. But in fact, this modification of the microprocessor includes eight integer modules and four floating semicolons. Therefore, in the first case, this CPU shows a high speed of work and is able to even bypass from the speed of I5 from the "Intel" of the 2nd, 3rd or even 4th generation. And in the second its performance decreases significantly, and it can already be competing with Core i3.

The basic frequency of the chip is 4 GHz. But when turning on the TurboBust mode, it can increase to 4.4 GHz. That is, it is an automatic acceleration of the microprocessor. Also, this device is unlocked multiplier. Therefore, it is possible to increase its performance by simply increasing the value of the latter.

The chip is equipped with three levels of the cache. The first of these allows you to place 384 CB of data and the program code, and the second and third - 8 MB.

The semiconductor base of the CPU is performed using 32 nm technology. This is an outdated technical process. Therefore, the chip has a high level of energy consumption that corresponds to 125 W. The supply voltage range is 0.9 - 1.3 V. The CPU crystal area is 319 mm 2, and the number of transistors is 1200 million.

Order an increase in speed

Most optimally carry out the FX-8350 acceleration using a combination of software such as AMD OVERDRIVE and AIDA64. This software is on the Internet in free access. It must be pre-downloaded and not installed on that computer on which this operation is planned.

The next step is a parallel launch of these programs. Then in AIDA64 go to the "Computer" menu item and open the "Sensors" subsection. First, we draw attention to the temperature of the processor. It should not exceed 80 - 85 o C.

Next, go to the Overdrive utility from AMD. In this program, open the CLOCK / VOLTAGE menu item. Then set the Select All Core checkbox. After that, using a slider change the multiplier value of the multiplier. Its basic value is 20. When using the cooling air system, it can be increased to 22-23. This will achieve frequency values \u200b\u200bin 4400 - 4600 MHz. If the computing system works stably, then in some cases set 23.5. This will allow you to get 4.7 GHz. In the case of the air system, installing a multiplier by 24.5 - 25. That is, you can count on 4900 - 5000 MHz. We save changes by pressing the Apply software button.

Now you need to go to the AIDA64 program. Check the readings of the sensors. If the temperature is within acceptable limits, then we leave this utility.

Check stability performance computers

After the acceleration of the AMD FX-8350 processor is fulfilled in full, it is necessary to check the stability of the PC. To do this, download such programs from the Internet as PC Mark, for example, and Crystalmark. With the help of each of them, check 2-3 times the stability of the computer. If the PC works correctly, then we leave everything unchanged. Otherwise, it is necessary to lower the clock frequency and re-email to check the functioning stability. You must also periodically monitor the temperature of the chip.

Performance growth

The increase in the clock frequency of this chip is from 15 to 20 percent. But an even more important factor that affects the increase in speed is the optimization of software. For example, if you have a test by archiving in WinRAR or in WinZip, you can get a fortyprotable increase in speed of work. But in those programs that are poorly optimized for a multi-threaded mode, an increase in productivity will be from 5 to 7 percent. The last group mainly includes toys.

The feasibility of performing this operation

The outclocking of the FX-8350 processor, as previously already noted, allows you to increase the PC performance without any changes in the computer hardware configuration. With its help, it is possible to obtain the level of speed of the computing system, comparable to the Core i5 of the 2nd or the same 3rd generation. Therefore, this operation is still relevant.

In addition, it has all the prerequisites for its implementation. The CPU is unlocked both a multiplier and operating frequency of the system tire. This allows you to flexibly increase the speed of the PC. At the same time, the incrementation of the multiplier is more convenient and practical way of increment. But the frequency of the system tire is incorrectly changed for the reason that the functioning of the graphics controller and RAM is tied to it. Therefore, such a way of overclocking may affect the performance of the computer.

Translation of the official instruction from ASUS ROG.

As you know, the acceleration of your processor instance may differ from the results of this article. Even the final result may affect the cooling and the motherboard (if you use the not specified fee).
If you have additional questions, you can ask them on the official forum (English) or in the official community in the social network VKontakte.

Well, let's go up!
Install the processor into the socket is quite simple and impossible to use efforts, otherwise you can damage the legs, and, accordingly, kill it:
-In the clamp
-The power processor combining the golden triangle with a trucal label on a socket
-Pusk the clamp

We apply a thin layer with a thin layer. It is very convenient to use something like a credit card if there was no special blades in the kit.

Set cooling. Remember that acceleration FX-8350 requires very good cooling! In our instructions, we use Corsair H80i, but the analogs are also suitable. It is best to use two section.
Install RAM.

A little about nutrition system.
As you could have noticed, the ASUS ROG Crosshair V Formula-Z board is equipped with an additional 4-pin processor power connector. Connections of both cables (8-PIN and 4-PIN) can improve stability in acceleration. But if your power supply has only one 8-pin cable, then do not be discouraged - the connection of the second is not at all.

Before we move directly to overclocking, download the latest version of the BIOS for your board and unpack it on the flash drive so that you can update the board via EZ Flash.

You still need to download (or take on the disk from the kit) and set the ASUS AI Suite II utility, since not all utilities can correctly monitor the temperature FX-8350. We will use AI Suite II to monitor temperature and voltages, CPU-Z to monitor the frequency of the processor and PRIME95 to test the stability of the system.

Make sure everything works in nominal mode.
Go to the BIOS and press the F5 key to apply optimal settings.
Save the settings with the F10 key and reboot in Windows.
Open CPU-Z and AI Suite II.
Run PRIME95 and run the Small FFT test. The processor frequency should be approximately 4 GHz.
In our case, the processor temperature reached 49 degrees. The room temperature was 25 degrees.

If everything is in order, then let's go directly to overclocking!
Once again, we note that there may be a very big difference between the processors, but most should be reduced to 4.8 GHz with good cooling. If you have an unstable system, then try to reduce the multiplier one step at the same voltage and check it again.
We will use the advanced UEFI BIOS mode (ROG line cards initially start this mode).
Follow in the Extreme Tweaker tab.
Set the CPU Ratio parameter to 24. Thus, we must receive 4.8 GHz (you can view the value of target CPU Speed \u200b\u200bslightly higher).

Set the memory mode at your discretion (by your memory specification). In our case - 1600 MHz.

In the same tab below, we are looking for CPU & NB Voltage and put on MANUAL mode.
We install CPU Manual Voltage - 1.5 V. Do not pay attention to the red lights of numbers, everything is in order.

We climb the menu slightly above and go to Digi + Power Control.
Install CPU Load Line Calibration on Ultra High.

Now we need the Advanced tab. It goes to the CPU Configuration menu.

You must set the Cool 'N' Quiet parameter to Always Disabled and C1E - Disabled.

You can still turn off the (disabled) Core C6 State.
You can save the profile of the settings (in order not to set everything again) in the Tool tab.
Now click the F10 key to save the settings and reboot.

Stress test
We repeat everything as last time. Run AI Suite II, CPU-Z and then PRIME95 in Small FFT mode.
In our case, the temperature in the load increased to 76 degrees. It is quite a lot, but still within TJMAX.

System stable? Then come back to the BIOS and try to reduce the voltage to 1.49 B and below. You can try to change the value of Load Line Calibration on High, but most likely the system will not work stable. Our processor instance was able to work at a frequency of 4.8 GHz at a voltage of 1.49 V.

AMD FX-8350 | Meet the AMD FX processor line based on Piledriver

We are, as computer iron observers, are not very interested in the problems faced by its manufacturers. Many will agree that last year turned out to be terrible for the AMD division for the development of processors, starting with the voracious CPU Bulldozer, which in twelve months slowly fell in response to the appearance of the third generation Intel Core processors. Recently, new samples entered our laboratory in Southern California. There should not be particularly worried about the disadvantages in the management, dismissal and gravity of the past AMD of the end consumers. So let's get down to business.

Sometimes it is possible to predict the ending of the article. If AMD sent us FX-8170, working on 200 MHz faster than the predecessor, it would be possible to assume that the processor will show the previous shortcomings in low current applications, it is likely to overtake the Core i5-2500K in more intensive tasks, but compared with 77 W chips Energy consumption will be just terrible.

But instead we got a processor AMD FX-8350which, by analogy with APU Trinity. presented for less than a month ago, based on the Piledriver architecture. The experience suggests that in performance on the kernel and on the tact of PileDriver can overtake the design of the Bulldozer by 15%. It is also worth considering that AMD FX-8350 will work at least 400 MHz faster than FX-8150. . By the way, the architecture provided a significant smaller speed increase in the Intel Core processor. A great chance that today's comparison will be much more interesting than the full separation FX-8150. In last year's review.

Meet FX Family on Piledriver Architecture

Being faithful to its tradition since Bulldozer, AMD sent the press the fastest models of the new line, which will include eight, six and four-core models. Although they are all built on the PileDriver architecture, the chips themselves are called Vishera, and will still be sold under the FX brand.

Crystal AMD Vishera.

The Vishera processor takes 315 square millimeters and consists of 1.2 billion transistors. Exactly the same indicators characterize the Zambezi of the previous generation based on the AMD Bulldozer architecture.

Two of the four processors use eight computing kernels or four Piledriver modules, as AMD calls them. Basic Frequency Flagship Model AMD FX-8350 Makes 4 GHz. In low current applications, TURBO CORE technology can increase this indicator to 4.2 GHz, although the chip speed increase will be associated with the base frequency. As far as Turbo Core speeds up AMD FX-8350? Not much. In a single-threaded benchmark, iTunes improved only three seconds.

In FX-8320, the base frequency is reduced to 3.5 GHz, but within the framework of the allocated thermal package TURBO CORE increases it to 4 GHz (acceleration by 500 MHz is greater for FX-8320). Both eight-core models are equipped with 8 MB of second-level cache (divided into 2 MB for each module) and 8 MB of L3 cache (common to all four chip modules). Recommended price by AMD FX-8350 is $ 195, and FX-8320 - $ 169.

The FX-6300 already has three active modules (six nuclei), and the price of a decrease to $ 132. The frequency of 3.5 GHz gives an architecture an advantage in multi-threaded tasks, and Turbo Core tries to compensate for the shortcomings in single-flow applications, increasing the frequency to 4.1 GHz. Like four-module chips, the FX-6300 uses 2 MB of L2 cache to each module (only 6 MB) and a total third-level cache with a capacity of 8 MB. The smaller number of active resources, as well as the lower frequency of the northern bridge (2 GHz) allow the FX-6300 to be within the thermal package of 95 W, which is noticeably different from 125 W of the Senior FX-83x0 processors.

The TDP of the two-module processor FX-4300 also does not exceed 95 watts. The value of the base frequency of 3.8 GHz in low current applications increases to 4 GHz, and the north bridge operates at a frequency of 2 GHz as FX-6300. However, the L3 cache container is reduced to 4 MB, and the price is below only $ 10 compared to the three-dimensional chip, which will encourage many buyers to spend extra $ 10.

The AMD architecture of a special disadvantage in memory bandwidth does not feel, however, a two-channel DDR3 controller officially supports the data transfer rate of 1866 mt / s. To reduce the total cost of the platform, we will use the low-delay DDR3-1600 modules, especially, according to the results of the tests (except Sandra 2013 Beta), it can be seen that having spent more money for faster speed gain you do not get.

All FX line has a unlocked multiplier, which greatly simplifies overclocking. Is the Vishera have enough acceleration potential? What about 5,125 GHz frequencies with the support of the liquid cooling system of the closed cycle?

AMD FX-8350 | Platform overclocking and compatibility

Acceleration

Although AMD processors have not received the title of the fastest, the company tries to keep the attention of enthusiasts, providing them with important functions for them. Software that allows you to change configuration settings in real-time, unlocked multipliers and platforms with a large number of PCI Express slots are just some of the key features that AMD offers people who know how to use them to increase the performance of their systems.

The same overclockers that were disappointed in the scalability of FX Zambezi processors with a conventional cooling system, this time will be very surprised, even despite the fact that we consider a very similar architecture on the same 32-nanometer kernel.

With the voltage of the CPU and the northern bridge of 1.375 V and 1,175, respectively, we managed to achieve stable operation AMD FX-8350 At a frequency of 4.8 GHz at full load. In the screenshot above, a single-threaded test for the "promotion" of the chip is launched, but the highlighted maximum temperature corresponds to the peak load of the entire test package.

AMD FX-8350 Could work even faster, but the key factor here is the tension setting at which the temperature will not exceed 70 degrees on the Celsius scale. At this point, the temperature sensor causes the nuclei to lower the frequency (the image above proves), a prevention chip from overheating and negatively affecting performance. Without giving multi-threaded loads, we even managed to start tests by 5.125 GHz (for this you need to set voltage A 1.4375 B for CPU and 1.2 V for the Northern Bridge).

Obviously, in most user systems a narrow place will be cooling. The reference radiator and the AMD fan, to put it mildly, is not enough, and the powerful third-party solution will increase the cost of the platform with the FX processor. But exclusively for testing, we used the liquid cooling system of the closed cycle that AMD offered together with the FX processors last year. It will cost you about $ 70. In this case, you can consider for $ 300 as an alternative. Fortunately, we have test results.

Overclocking up to 4.8 GHz is enough to AMD FX-8350 overtaken in a multithreaded 3DS MAX 2012 type, but it did not help the AMD Piledriver architecture bypass in the iTunes single-threaded application. Of course, if you are ready to spend an extra $ 30 to and even more on the side cooler, then its base frequency can be relatively easy to zoom in from 3.5 GHz to 4.5 GHz and will be filled with AMD FX acceleration.

Compatibility

Review of the FX 8350 processor from AMD, we got acquainted with the architecture of Piledriver and made it a comparison with predecessors and one of the competitors. It's time to supplement our review. Today we will study in detail the acceleration potential of AMD FX 8350 when using various types of cooling, as well as test performance testing in 3D applications.

To assess the overclocking potential of FX 8350 and further testing, an open test stand was used, with the following configuration:

• Motherboard: ASUS SABERTOOTH 990FX (AMD 990X, AM3 +);
• Processor: AMD FX-8350
• Cooling CPU: Air, Water, Dry Ice
• Thermal interface: Arctic Cooling MX-2;
• Video card: reference Sample AMD Radeon HD 7970;
• RAM: KingMax Memory 2x2 GB PC3-10700H (DDR3-1600);
• Drive: Seagate ST3250410AS 250 GB;
• Power Supply: ;
• Operating system: Microsoft Windows 7 x64 Ultimate SP1;
• Driver version: Catalyst 12.11 Beta 8.

Overclocking

At the final frequency of the processor after overclocking, besides its personal frequency potential, a number of factors, such as the type and efficacy of the selected cooling, the supplied voltage, as well as a number of other, equally important factors. Today, the main purpose of experiments with the AMD FX 8350 processor is to obtain approximate overclocking results using different types of cooling. We believe that these results will be approximately valid when overclocking any other instance of FX 8350, they can be relying on them as a kind of reference.

All experiments with frequency were made directly from the BIOS motherboard, we did not use software overclocking from Windows. Acceleration was carried out by increasing the multiplier and voltage on the CPU kernels. The CPU / NB and HT Link Speed \u200b\u200bfrequency was recorded at 2400 MHz and 2600 MHz, respectively. The value of the CPU Vcore Load Line calcration parameter was set to High, it was in this mode that the voltage in the load was as close as possible to the installed. The processor power system is constantly cooled by one 120 mm cooler. The stability of the processor was determined using the LINX 0.6.4 program, finally the processor temperature was monitored by the ASUS Thermal Radar utility.

All measurements were made using Mastech My64 multimeter.

Search for the detection of instability

Software selected to identify instability can be divided into three categories:

• Programs originally oriented as stress tests of the system. In this category hit LINX 0.6.4. (Testing was made in 2560 MB mode for the old version of Linpack, as well as in three modes, with an accessible memory of 1024 MB, 2560 MB and 6144 MB for the latest version of Linpack, with support for FMA instructions), OCCT 4.3.2.B01 (Test CPU: OCCT in Large Data Set, Medium Data Set and Small Data Set modes, as well as the CPU: Linpack test in AVX mode with 90% of the available memory), PRIME95 V27.7 Build2. (in Small FFTS, In-Place Large FFTS and BLEND modes), CST 0.20.01A. (Combined test, including MATRIX \u003d 5, MATRIX \u003d 7 and MATRIX \u003d 15) modes.


• Programs used as system performance tests, or emulating one or another load, occurring in the daily work of the PC. Fit here Cinebench R10. (test X CPU), Cinebench R11.5. (Test CPU), wPRIME 1.55 (Test 1024m), POV-RAY V3.7 RC3 (Test all CPU's), TOC. [Email Protected] Bench v.0.4.8.1 (test DGROMACS 2), 3DMark 06. (Test CPU1 + CPU2), 3DMark vantage. (Test CPU1 + CPU2) and 3DMark 11. (This time, separately Physics Test and separately Combined Test).


• Several processor-dependent games. They entered COLIN MCRAE DIRT 2 Deus Ex: Human Revolution (Detroit), F1-2010 (Built-in performance test), Metro 2033. (Built-in performance test), SHOGUN 2 Total War (Battle with Okhekhadzam) and The Elder Scrolls V: Skyrim (Manor "Zlatootzvet").

For stability, the state of the system is taken, in which during 10-15 minutes of the test does not arise any problems in its operation.

Processor instability

In this subsection, we will choose software, with which it is easier to identify the instability of the processor, with obviously stable memory frequencies and CPU_NB. The technique is relatively simple: with a fixed value of the supply voltage, select the maximum overclocking for each of the programs and calculate the test at which the minimum frequency of stable operation will be achieved. Well, in parallel, the search for stable frequencies can also be evaluated by the behavior of the system in reworking for one or another test. In order to avoid instability caused by the overheating of the CPU, all the tests were performed at the power supply voltage of CPU 1.25 V.
