AMD FX 6300 Hard Crashes my PC

[Sparkychuu]

I had an AMD Athlon II and ordered an AMD FX 6300. I was impressed how much better it is cause i never had a good CPU buuuuuut theres one big issue. I get really random crashes, even if i do nothing. I'm veeerry sure its not the temperature. It's around 26°c in idle and around 40c° if i do something (i don't do high end stuff on my pc anyway). I tried disableing "Cool n quiet" but that didn't really help. I did not overclock it or anything~

Pc Specs:

CPU: AMD FX 6300
RAM: 2x 2GB RAM DDR3
Mainboard: MSI 760GM-P23 (Fx)
GPU: AMD Radeon Saphire 7700

Did you upgrade BIOS ? That's an really old chipset barely enough to run FX processor which support was just like an afterthought.
Another limiting factor may be that Athlon is a 62W processor and FX6300 is 95W so VRM section may be inadequate and heating up but without sensor can't read temps.

What kind of power supply do you have? That board is quite old and may have hard time supporting a 95w cpu as well.

Describe the crash. Does the system just lock up without presenting any errors, is it a blue screen or any sort of error screen?

@CountMike i have the newest BIOS version.

@MisterMeow idk what kind of Power Supply i have, im a noob when it comes to PC stuff :x
The Screen freezes, nothing is working and i have to turn of the Power to restart the System

Can you open the case and see the power supply? It should say right on the side what wattage it's rated for.

That kind of crash suggests a hardware failure. The temps are fine, but if these crashes only started happening right after installing the fx 6300, the issue is probably with your motherboard not being able to support the 6300's 95w tdb, or it flat out isn't compatible and you may be able to flash the motherboard BIOS. Another reason could be a DOA cpu or the power supply is just too poor quality. So information on what kind of power supply is in the system could prove useful.

If you stick the Athlon back in the system and the problems disappear, then it would eliminate a fair bit of variables as well.

Ok i checked what kind of Power Supply it is. It's a 400w Power Supply by FSP Group (?).

I can confirm that the Athlon still works.

I noticed something though. I deactivated "Cool n Quiet" and "AMD Turbo Core something" in the BIOS (it was automatically on) and the crashes are more rare now.

It seems like others use the Same Mainboard and the same CPU and it works for them. Maybe its something else?

hmm, idk what the prob is but i would recommend a steam machine.

That power supply might be your issue. What model is it? If aren't sure, you could take a picture and post it. But if turning off turbo boost made a difference, there's a chance it's an issue with the power delivery. Either the motherboard or the PSU, try underclocking the cpu a bit. The cpu multiplier should be 17.5x, try 15.5x and set the vcore voltage to 1.21-1.22v if your board lets you. If the crashes stop then it means the chip isn't DOA. However, it could still be a defective cpu that just doesn't operate under its factory parameters, but that's much less common then a bad mobo or PSU.

Underclocking it solved it i guess. No issues anymore! I don't care if the CPU has a worse performance now, i don't notice it and im not a "gamer" anyway! Thank you <3

 

[MisterMeow]

No problem. In the future, you may want to pick up a new power supply and that will probably fix your issue. No more underclock just for stability. a quality 500w psu is around 45 dollars or so and would do just fine.

I never really touched a PSU and setting it up looks veeeeeery complicated

 

[MisterMeow]

It's really not. It's as simple as fitting the right shape into the right hole. 20+4 pin, a 4-pin cpu plug, a SATA connector or two for the drives, a 6-pin PCIe plug, and a few screws. And you can always use the old psu as a reference. Just remember or take a picture of what's plugged in where.-

The only thing hard about it is cable management. That's much more difficult. Finding the right place to stash all the wires so it looks nice and clean.

I had the same issue when I upgraded a Phenom 2 based system to an Althon FX CPU and never really have been able to solve the constant freezing issue. (also AMD 7xx based board, only this is a Gigabyte).

However, from what I have learned over the years researching this problem, it's because the Athlon FX CPU's have a CPU manufacturing bug in them which makes them hang, freeze several times a day and it just can't be fixed, these CPUs are just bad. It can be really frustrating, but the freezing is mostly on Windows, while on Linux the freezing almost never happens (but it isn't immune to it either, mostly it can be triggered by the Flash plugin on Linux)

I doubt it's the PSU if this is the same issue what I am having, as this is caused by a CPU manufacturing bug, replacing the CPU cooler with something a bit heavier can help a little (something I did), but the issue won't go away completely.

I think the only solution is a new motherboard, RAM and CPU, I am going with Intel next time.
