Memory problem

[fredericb]

Hi

I recently got a kit of quad406-8500c5df dominator kit replaced on warranty, i received the parts wednesday and installed them on friday

I ran the ram at 2.15v (closest to 2.2 without being over)

It was working all good until this morning, i got a crash and the comp wouldn't restart

play with the dimms, i got one that wasn't working except in the 4th slot while all the others are filled in

so i ran memtest, everything looks fine

i played crysis, the game crashed then windows throwed some errors around

i reboot and run memtest again and i get around 20k errors at the 3rd test

 

The boards look fine and it's currently running old ram that i had laying around (ocz platinum). Ran memtest again and everything is fine.

 

So what could have caused the ram to fail when it was brand new (well replaced but still)

 

currently, the exact setup is:

intel q6600 oc to 3.21g

asus p5b-deluxe

frontside bus at 355, ram runing at 710 (even the dominator was runned at that speed)

bfg 8800gtx

All of those parts are watercooled (cpu, nb, vreg and video)

 

If it's the board that could be causing the ram to go bad, i'm willing to replace it for a maximus formula.

I did more test on a second board, 1 dimm is not working at all, all the others are fine, alone or all 3 installed

They all (well exept the non working one, the comp doesn't boot) ran memtest for 2 pass and completed it without errors

The board is a asus p3k-vm and everything was at auto value, the ram was set by default at 800mhz by the board

When you had the previous issue, did you have a single module fail? If so, do you recall if it was the same slot as the current failure?

[fredericb]

i did not do all these test to see if there was the same problem

But on the p3k-vm, i was able to boot once with all 4 dimms

entered the BIOS to configure the time, save the settings then reboot and it never booted again

 

I did try to move the ram around on my p5b to see if it was a specific slot, it seems that the dimm that failed came from slot 1 because i inverted the dimms positions.

Please make sure that you have the latest BIOS for your motherboard and then load optimized defaults and set the Memory Voltage to 2.1 volts and then set the timings to 5-5-5-15 (CAS-tRCD-tRP-tRAS) and then test the modules one at a time with http://www.memtest.org! Please allow memtest to run 2-3 passes on each module. If you still get errors, we will be happy to replace them!

 

Make sure when running memtest you have “Legacy USB Support” disabled in the BIOS.

I did this test on the p5b deluxe, got 20k errors with all dimms set

with each dimm at at time, i have no errors with any dimms except 1

the 1 that fails, the computer won't boot at all
