RAM Problems.

Asus Maximus Formula Intel X38
Corsair Dominator 8GB - Retail 5-5-5-15 2.10v 533MHz 3:4 2T Fan Cooled
Intel Core 2 Quad Q6600 "Energy Efficient SLACR 95W Edition" - OC 3200MHz 400MHz*8 1600MHz FSB

OK, I really cant figure it out, and its really driving me quite quite mad.
At random times, be it 12 to 48 hours I will get blue screened. I know its a RAM problem, so I run MemTest+ (Boot) and it will report errors.

I test the ram singaly.
Some will error, some wont.

Even if I run with only 1 stick (2 gig) I will still get a BSOD.
MemTest+ again, reports errors.

If I now switch the stick with another one that errored in the past, rerun MemTest+ it will now report no errors.

Windows runs fine again for anywhere between 12-48 hours and I will BSOD with MemTest+ errors.

Repeat cycle.

Same results even if I run CPU at retail.
I've tested each stick in each slot, thats 16 tests, no errors (When it decides not to BSOD)

Any ideas?

Thanks, ill try 2.2/2.3 and see how it goes.

Sorry I couldnt explain it better, I'll try again.

Just say I use 1 stick.
Somewhere over 2 days it will error.

I now swap it with another stick. No errors.
Somewhere over 2 days it will error.

If I know swap it back to the 1st stick. No errors.
Somewhere over 2 days it will error.

Same problems.

Was running all 4 sticks. Errors.
That was 5-5-5-15 2.20 and 2.30
Retried with 7-7-7-17 2.20 still errors.

Took 3 out, reran at 5-5-5-15 2.20
No errors.

Gonna MemTest each one seperatly and ebay them.
Anyone have new RAM suggestions for my Mobo and current OC?

Thanks.

NB pushed to 1.55v (1.57 in windows 54c Temp)
4 sticks, 6-6-6-18, 2.30v (DIMM voltage 2.38 in windows)

MemTest+ passed.

I'll see how it goes during the next couple of hours.
Is the voltage on RAM ok?

Thanks.

Ok,
Droped back to 5-5-5-15 2.20v
Increased NB to 1.60v

Was downloading 20+GB files from work over night, was stable, no BSODs.
All files where verified and not corrupt, which is usualy how I can tell the RAM is playing up without a BSOD.

Looking good, I'll see how it goes throughout the day.
Fingers crossed.

Thanks for the help.

Yeah, I did think of that.
NB hitting 60-65 C depending on chassis fans.

Not much luck, I can lower the voltage on the NB a little but it still runs in high 50's

Only reason im worried about upping the RAM voltage is because I cant afford to RMA my sticks. I have a lot of work to do...

Now, a little question. Would 1.60 volts or just a little lower damage the motherboard or is it only a heat issue?
If its only a heat issue I could get 1 or 2 40mm fans?

*Edit*
Been reading up on the board, and it looks like 1.60v on the NB is acceptable
Considering 1 40mm fan.
