Hey guys.

I am curious on what others think about stress and burn in tests.

I've been doing quite a few different tests on my new build's hardware since everything is still under warrenty and if anything proves to be defective, I can get it replaced.

So far, it has been a headache. Between 2 different FX 8350 (8 core) cpu's, I have run Prime95 tests which always drop at least 3 cores, OCCT tests which at first didn't fail but now do, and Sandra tests which always show errors between a few different pieces of hardware.

My frustration lies with both these cpu's being new from Amazon.

Can someone help settle my frustration? Because it seems like I could get countless replacements from Amazon and they would show similar results.
 
How do you know the processors from Amazon are defective? The system has been tested with another FX-8350 and it didn't fail the stress tests? If you only tested 2 FX-8350, then I'd presume there's an issue with the PSU or the motherboard. Does the motherboard fully support that CPU?
 


Yes, both the AMD FX 8350 processors fail cpu stress tests using Prime95, OCCT, and even Sandra.

Yes, the motherboard fully supports the CPU

From Asus website regarding my M5A97 R2.0 motherboard:
AMD® Socket AM3+ for AMD® FX Series CPU up to 8-core
AMD® FX™-Series/Phenom™ II/Athlon™ II/Sempron™ 100 Series Processors (socket AM3+/AM3)
M5A97 R2.0 supports AMD® AM3+/AM3 multi-core processors with unique L3 cache and delivers better overclocking capabilities with less power consumption.
 


I am going to update my BIOS right now and will report afterwards.

I'm not sure about the DRAM. Although, I confirmed that my ram is fully compatible here.
 
You can check the BIOS or firmware version number in your motherboard's UEFI BIOS. Or you can through windows with effective simple tools like CPU-Z or HWInfo. As long as the version you are using is not at all buggy and later than, let me check.....BIOS Version no 1006, that is the first BIOS update for the second gen Bulldozer Processors, aka Piledriver. I'd say the were at least one or two after that can improve stability and compatibility.
Also check to see if your Motherboard is on the lower voltage low power, environmentally sound, EPU ....forget the exact term for it. green setting.
Use Advanced settings to ensure sufficient power to the CPU.

Burn and stress testing is key to being sure that your PC is functioning as it should and will handle what you throw at it for years to come. The probability of your CPU's (any that you have tested) actually being bad is unlikely. It sounds more like your overclock isn't a good one. Are you overclocking via software or are you overclocking in the bios? What hardware do you have: cooler, power supply, ram?



The M5A97 is a good motherboard but it is truly only designed to overclock the six core processors. If you want to effectively overclock the octacore for long periods of time you will want a 990 chipset.
 
Well honestly, I'm not overclocking. I was just advised to run these tests for the reason you said which is to test my computer's stability because it seems to be lacking performance.

My whole build is this:

CPU: http://www.amazon.com/gp/product/B009O7YUF6/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
MOBO: http://www.amazon.com/gp/product/B008V9959O/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1
PSU: http://www.amazon.com/gp/product/B00390P1NO/ref=oh_aui_detailpage_o07_s02?ie=UTF8&psc=1
RAM: http://www.amazon.com/gp/product/B00CWR3I2G/ref=oh_aui_detailpage_o07_s02?ie=UTF8&psc=1
I also have a 120gb SSD and a custom XSPC waterloop running.
 


I've never had good experiences trying to overclock crucial RAM, and of all the RAM we have ever used in the shop (G.Skill, Kingston and Crucial) we have only ever had crucial come back to us and had to be RMA'd. The power supply should be fine as long as you aren't overclocking. It is a good unit, but a little low on wattage to support overclocking.

If you want to replace your motherbaord with a 990 chipset board that would be cool, but if you are going to run at stock clocks the entire time you have your system and your temperatures are fine then I wouldn't worry about it. You build seems a little off balance but overall ok.
One thing I do know is that your processor (and all the ones before it) is fine. If your processor was defective your PC most likely wouldn't be functioning properly and defective CPU's are very rare.
 


I must be misunderstanding what the stress tests do or what overclocking is. Are the stress tests trying to overclock my pc and since it isn't set up to be overclocked, it's having errors? How come the OCCT ran fine at first but now it doesn't?

Is anyone willing to IM me?
 
Aida64 is really good and worth taking a look at . Try it free. Anyway All these tests (aka CPU Virus,) are pretty much designed to make a system fail , sometimes even freeze up entirely.
With Prime 95 , how long before the test reads an error? Did you take a screenshot? What are the temps? (Use Core temp for AMD) , Why am i asking this now....don't answer that one.
 


Hey guys, good news. I reinstalled my operating system to pretty much start fresh and also raised my DRAM +0.05v like you suggested Tradesman.

I ran OCCT and it was successful. No errors so I stopped the test after an hour. Here are my results if it helps: http://postimg.org/gallery/1ygn06axe/

Looking good? Is it worth running Prime95 too?
