Its only a 2month old build..
I just ran a prime 95 test on my pc and the pc gets restarted after that pc gets into boot loop it won't start after that just boot loop
mad.gif
The pc only start only after I disabled four cores from the bios This is not the first time happened with me I used to reset my Bios and format my pc to get it working except prime 95 my pc passed most of the stress testing like Intel Burn TEST
BUT this time i am not able to format my pc whenever I try to format my pc it just gets restart while on the loading on the Loading Screen:devil: but if I disable my four cores it works perfectly...
I haven't bought this processor to work as a four cores processor amd you are testing my patience or this my motherboard fault I am having asus m5a78 lx v2 I know it is Not a Good a Motherboard but I think it can Handle fx series at STock setting

My other sytem specs
psu:corsair vs550
ram :Kingston Hyperx REd 4gb
graphic card:sapphire hd7850

I tried almost all possible settings from the bios I tried 3 different bios version all possible voltages cleared cmos using jumpers on the motherboard nothing helped

This post is my last hope the service centres are very far from my home what should I do..? plss guys any suggestion pls help
I Think I got the super Bad chip:p

It could be something as simple as a stand off shorting out something on the back of the motherboard. Take your build and put it on the box the mobo came in. The cardboard grounds it out fairly well to rule out the case being a problem.

I think there's an issue with the board. It appears that it can't power the full 8 cores anymore. Do yourself a favour and get something that more suited to that CPU. I think it may have been damaged when you were stress testing.

Before you go off complaining about AMD and the 8320, take a look at the board specs by ASUS:
http://www.asus.com/Motherboards/M5A78LM_LX/#specifications

Although it supports FX CPUs, it also clearly states that it only supports up to 95w CPUs.
It had worked with your 8320, but it isn't designed for such hungry CPUs which put a strain on the VRM circuitry and other components.

Get a different mobo and your CPU should function normally.

^^^^This. That board wasn't designed at all for your CPU. I'm assuming you're Indian, like me, so get this board instead.

It's no overclocking monster, but it'll do your CPU at stock just fine. It supports CPUs upto 140w.

^^^^ even 125w boards can barely run the 8 cores and that is why its recommended to run the 140w ones. You didnt happen to try and update your bios and place a fan on the vrms, i would say your vrms are overheating since there is no heatsink on them, place a fan blowing directly on them and maybe add some gpu memory heatsinks or something to them if you plan on trying to keep that board

I've seen people run with the M5A78L USB3 and FX 8350 just fine. It's perfectly OK if you're gonna run stock. The OP's board on the other hand, won't. It's the LX model, which has a 95w limit.

if something is shorting off then the pc won't start with four cores also

My bad. V2 does support 125w CPUs, but I truly believe there is nothing wrong with your CPU and the culprit is most likely the mobo.

Do you have another one to test with ? maybe borrow one from a friend for a few hours .....

You could try a bios update possibly but as has been stated in this thread the board isn't suitable for that CPU. There really isn't too much you can do but hope it works or just game on 4 cores until you can afford something more suitable. I would see if I could exchange it if it's not too late. Have you contacted ASUS about the issue? Like I said earlier there may be something physically wrong. I understand you have used it but from what I read you tried to stress test it and now only four cores will work. What do you have for a powersupply?? It's possible that could be the issue but I still think it's the board.

It would seem the PSU is not delivering enough power for the 7850 and 8320 with Turbo enabled.

Although the VS series is an entry-level unit (quality wise), your system isn't pulling more than 350w when under full load to stress the PSU.

EDIT: I see your mobo has an onboard GPU, can you remove the 7850, connect the monitor to the iGPU, enable Turbo and check your 8320 then?

I tried almost 3 different version of Bios But no luck..

It's still helful to know the brand and model of the PSU. If it's a multirail it may be overdrawn. It's easy just tell us. Software isn't accurate at times and the important part is the Amperage available for the CPU
