MemTest error

[Qrox]

PC Specs are in my signiture.

I decided to upgrade my PC in February. I upgraded the motherboard, CPU and RAM. For the first month I didn't really have any problems. Then at the end of march I started getting more and more BSOD events while playing games, watching videos, browsing on chrome, booting into windows or even just opening a folder.

I decided to format the PC to make sure that it wasn't a OS related issue. At this point I could no longer boot into windows and got about 30 BSOD before taking my PC to a shop so they could see if they could find out what was causing this. They tested the system for 3 days and could not find anything wrong. I plugged it in at my home and immediately got a BSOD.

My friend lent me a Corsair Vengeance 8GB kit (Same as I have in my system, just the blue heatsink version) and Immediately the BSODs stopped happening. I sent in the RAM kit but they couldn't find anything wrong at the supplier or at the store, yet when I put them back into my PC I started having problems with BSOD again, though not as frequently as before.

I contacted Corsair and they told me to run MemTest with one Ram module at a time. First module passed successfully. Second module got 5 or 6 MemTest errors. When I took it to the store this morning, they tested the module that I found the MemTest errors on and could find no errors again . . .

I sent Corsair another message and I'm waiting to hear back from them, but does anyone know why nobody else can find the MemTest errors? As stated before, when I put my friend's kit in, I don't have any more problems.

Could be a timing settings in your BIOS. But if you got the error twice after getting your entire system back and they couldn't pick it up after 3 days then I find it hard to believe they were testing it.

How long was the "faulty" RAM module receiving power before running memtest (both by you and the shop)?

I'm thinking of the possibility of a hairline fracture on the RAM module; this would potentially result in a circuitry issue as heat builds in the module due to inherent electrical resistance. It's the only explanation that I can think of that you can cause it to fail but the shop can't, as such an error would manifest itself over time (typically around 15-20 minutes, but can be significantly shorter or longer).

(EDIT: StarBound's suggestion is also valid; try resetting the BIOS values back to failsafe settings.)

I've been going to the shop for years and know the guys that work there so I know that they didn't just let my pc sit in a corner to collect dust. When I stopped by one afternoon I could still see them testing. I'll have a loot at the timings as you suggested tomorrow and report back.

When I tested the first module it was still a bit warm and it gave no errors. When I tested the second module it had cooled down to room temp and I got the error. This morning it was also cool when I gave it to the shop to test. He also showed me the MemTest result after the test with no errors.

Also I'm getting the blue screens both when I have overclocked my cpu and set the ram to 1600 as well as when I reset everything on bios to default with ram down to 1333. Unfortunately I don't have time to test anything tonight. I will try some of the things suggested so far tomorrow morning and hope let you know how it went.

Corsair sent me a message saying that I should RMA the modules so thats what I'll do.

And just as I thought things were looking up... my GFX card decides to give up on me... what are the odds of that?
I just sent Asus a mail as well as I already know that computersonly, only give a 1 year warranty on products while Asus has a 3 year warranty on their products.
