Overclocking killed RAM?pc works but getting random BSod.

[darksmart]

My friend accidentally set the RAM frequency to 1066 in the bios of his biostar 785 mobo.after that he rebooted but pc was unable to boot.so he did the cmos rset(jumper method).then pc booted successfully and he set bios to default but since then,he is used to get Blue screen of death after some time of operation.Though the pc runs very fine for some time,can even play games like gta 4.but gives BSod randomly.could it be the ram or some other problem?


specs-
Phenom x6 1055t
2gb transcend jetram
biostar 785 mobo
radeon hd4850
windows 7 32 bit
coolermaster real power 850w

Give your friend the .iso bootable CD file for memtest86+ (1/2-way down the page), and have him assign it as the first boot. Let memtest86+ run, if it completes it passes with no errors, his RAM is working at the voltage, frequencies, and latencies set in the BIOS.

We did a memtest using usb version.It says "test complete no errors.press escape to exit".
does it mean that some other hardware has malfunctioned?or should we try reinstalling windows 7.Also we have placed the ram in the slot previously it was.

Your results indicate the RAM is fine. Have your friend record the error code(s) on the BSOD(s), and post them here.

I would also check Device Manager looking for yellow question marks or exclamation points - resolve any shown. If there are none, then try to determine what your friend is doing - the programs and processes he's using when he gets the BSODs. Make sure he is running only one anti-virus program.

You could reinstall W7, but it sounds like he may have the same situation he has now. Of course, if nothing else works, then do the re-install.

 

[darksmart]

he was only able to read dumping physical memory.and there are no yellow question marks or exclamation points in device manager.he has avast free AV.

 

[treefrog07]

OK, no HW errors or problems in device mgr, and just one AV program.

On the BSOD showing the "memory dump" There should be reason, like hardware, or a STOP error with a series of letters and numbers. What does it say?

 

[darksmart]

he placed the ram in the slot in which it was placed earlier i.e before getting BSod.
But does the Ram slot makes any difference?

 

[treefrog07]

Depends. Probably not in his case because the RAM passed memtest86+. Sometimes a DIMM slot goes bad. And sometimes a RAM stick goes bad. Memory is difficult to diagnose - that's why memtest86+ is so helpful.

Has he updated drivers recently, espeically video card drivers? Those can cause BSODs.

 

[darksmart]

nothing.all drivers an rest of the system is same including installation of windows 7.

 

[treefrog07]

His problem is not from OCing his RAM.
I wonder if his electrical service could be coming into play. I don't know where you are, but this summer we've had occasional brown-outs and voltage spikes in SE Virginia from everyone constantly running the air conditioing. I use a battery backup that saves me from getting BSODs from a problem-electric service (and also tells me when those events occur).

 

[darksmart]

may be not.plus we all use ups,surge protectors.the problem starting showing up right after overclocking.the cpu was turning on but monitor remains off and no boot up.
even after resetting cmos,the the pc booted up but after some time,we were getting Bsod.it happened 3 times.and then we decided to put the ram in the previous slot.and that solved probs.
cannot understand why that happned?
