Right lets start off with this being my first post on the forums ;) So hello all :)


Sorry for the long post guys, try and decipher it best you can :)

Right - lets start with the specs

Motherboard : Gigabyte P55 UD3
Processor : Intel I5 760 (Overclocked to 4.8 GHz)
Cooler: Corsair H60
Ram : Corsair Vengence (8GB) ***It was OCZ Gold 4GB***
Graphics : AMD 6850
Sound : Xonar DX
HDD : 1TB Samsung F3 Spinpoint
PSU: 520 Watt Antec HCG
Samsung Blu Ray Drive

Right the problem is, the pc started to randomly restart - No BSOD just a message when i reboot that the pc just restarted from an error with no other informaton.
The first thing I did was virus scan, Spyware etc and then update all drivers and windows update.
I thought that may of worked however I was not too sure seeing as certain games (Metro 2033, Total war 2 and Battlefield 3) worked all fine but every so often would slow down to a complete halt then speed up.
I was not to sure what it could be but I tested power and is working fine, checked voltages all seem perfect even put all to stock speeds and it still had the same symptoms.
I then thought it may be the RAM (This is using the OCZ Ram) so i downloaded Prime 95 - this refused to run. I then tryed Memtest86 and got around 12 errors in the first 15 minetes then all hell broke loose I got around 65 thousand errors within seconds and it was rising QUICK.
I reseated the ram and tryed again exactly the same so I thought 'faulty ram' joy -_-.

I returned the ram and then said when they tested it they got no errors (they claim they tested i for 4 hours) so as Im speaking its on the way to manufactor's for a replacement.
Well this is the next confusing part, Ive just purchased off a friend some Corsair Vengence RAM he loaded up Memtest on his and showed me there is no problems with it and he was right not 1 error for around 6 hours but soon as I put it in my sytem in the first hour I got around 3000 errors on the RAM (but Prime 95 did not report any errors which i found very odd).

So you can see my dilema is my system just ruining the RAM or is there a fault elsewhere?

Any help will be very much appreciated :)

Thanks guys,

I did Think that, however I not entirely sure about this but if it was a faulty slot then surely any RAM that I put in there will stop at the same point as the OCZ ram and rack up 65k+ errors or just not work at all and not register it.

How long have you had the Corsair H60 fitted?

Overtightening the 4 screws securing the block/pump can cause the motherboard/cpu socket to warp leading to problems with the RAM slots.

Try loosening the 4 securing screws a turn each and see what happens.

You obviously don't want to loosen them too far otherwise the cooler block won't make proper contact with the CPU.
 
I've had the H60 fitted for 18 days lol I will give it a try, I think I'm going to take it all out and rebuild it and rewire it all up again and see what happens :)

Just try loosening the cooler a bit first.

It's worth a few minutes of your time if it saves you rebuilding the whole PC.
 
I adjusted the cooler, all seemed well till I had to restart the PC and it turned on, loaded up then restarted and told me that Windows had to shut down due to a unexpected error.

I did a Prime95 stress test for 6 hours through the night out of the 4 workers, 1 failed 33 min into it saying :

"FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file. "

That was on worker 3 that failed the other 3 kept on going and going and passing lol
