Audiovisual glitches after changing my AMD CPU

Greetings. I use old hardware, reason being mainly accessible prices. Recently I replaced my processor (An Athlon II X4 620 I've been using since 2011) for an FX-8320 Black Edition, which has the same socket but is a pretty steep upgrade despite also being somewhat old. After installing it on my Motherboard (an ASUSTeK M5A78L-M/USB3 I bought in 2014) strange things began to happen. Windows started normally, perhaps faster, but there were random visual and audio glitches on everything I ran, seemingly harmless but ever-present, specially browsing resource-heavy internet websites or playing any form of audio or video files. Games launch without problem, but all audio drowns in strange static noises and all geometry seizures wildly across the screen.

I rolled drivers for everything backwards and forwards, same goes for the Motherboard's Bios, I even changed my OS but it didn't fix or diminish the problem. I tried then to replace my current Graphics Card (GTX 1050 Ti) for my old one (GTX 550 Ti) to see if it was a matter of compatibility between GPU and CPU but the problems persisted. I had settled on the problem being the CPU being somehow damaged or faulty (despite reading perfectly on diagnostic tools such as Speccy), when I discovered that the problem goes away for individual programs if I reduce their affinity number through the Task Manager to any 2 cores or less. It's bizarre considering that the previous CPU had four cores and nothing like this ever happened.

I have hope that this is somehow a software configuration problem, and that it can be solved to make the computer work well with the FX-8320, I've temporarily disabled 6 of the 8 cores so that I do not have to manually set affinity numbers for every program, every time I launch it, but it's a makeshift solution, as it takes away the reason for the upgrade in the first place. I do not know what diagnostic files or logs would be of use to put alongside this post, but I can dig out anything that could help diagnose and solve this problem. Many thanks in advance.
 


Hello geofelt, and thanks for your reply. I admit I have little depth knowledge on CPUs; I assumed all I needed to worry about was the socket matching my motherboard. Is there some measure that I can do or revise somewhere to be certain of these power phases not being suitable? Maybe one of their specifications that I can compare? Sorry if it seems I ask things too elementary.
 
After some further reading on a few other threads here and other websites I learned the concept of TDP, which appears to be what I was missing. My previous CPU had a TDP of 45 W, while the new processor has 125 W, which is nearly triple. However the motherboard I currently have has a rather strange thing where someplaces it is referred to have a capacity of 95 W, and in others an astounding 140 W. It's confusing. Then again, I am yet not entirely sure it is the value I should be looking at.
 


Hello kerberos_20, and thanks for your reply. I have indeed updated my BIOS to the latest available version, without having an impact or visible effect on my problems. If my motherboard indeed capable of supporting the CPU, I would have to default to my original assumption that either piece, the motherboard or the FX-8320, is somehow damaged or faulty somehow, although I have no knowledge on how to properly test this for confirmation or a more specific prognosis.

This link is I think a very in-depth analysis of my current hardware configuration. From a program called CPU-Z. Hopefully it helps shed more light to this problem.

 


Thanks again for your quick reply, kerberos_20. To be honest I am unsure as to what that is, which I guess is also a strong "no I haven't" to your question. I search online about this, but I might be wording it poorly since all results lead me to ATI GPU drivers which is completely unrelated. Please, do tell me more!
 


Thanks yet again. I do have those installed. The controllers and drivers that come in a disk with the Motherboard (somehow the word Chipset didn't set in despite the dvd being labelled with it). I tried installing the ones that had a newer version than what I had, but the problem persists. It's quite frustrating.
 
Through the usage of a few overclocking programs and some testing with the guidance of some more knowledgeable friends, I've managed to nail the problems to two specific cores of the processor, cores 3 and 4 to be precise. It is whenever those are active that the problems happen, and disabling them entirely from the BIOS configuration has solved the problem. Thanks again for supporting and advising me through this ordeal, shortlived as it was.
 


"Supported" and being "adequate" are two totally different things. That board is totally inadequate to run any Vishera 6 or 8 core cpu.
 
Indeed, I was not overclocking as it seems hazardous without the elementary knowledge of hardware capacities and proper handling. It took me asking here and two full days of reading online resources to even approach those elementary concepts after all.

Even with the suspect cores disabled the computer has performed well, visibly better than what the Athlon II could achieve in fact. Unless the other cores begin to degrade over time I believe I will continue using this faulty Vishera until financial circumstances let me purchase something slightly less obsolete. Thanks again for your patience and guidance.
