Corsair 2Gb 3200C2PT MemTest Errors

GravyMonster · 18 Apr 2006 at 10:13

Hi all

Just stuck my new machine together with 2x1Gb Corsair 3200C2PT sticks and a DFI SLi-D and I'm getting random instabilities with my memory, programs crashing, hanging during boot etc.

Anyway i ran MemTest and for tests 5 and 8 the screen just turns red, about 70 errors in one complete pass at 2-3-3-6-1T IIRC.

Slowing the memory down to 3-3-3-8-1T showed no errors in memtest, but the machine still CTD'd in Sim City 4.

I've put my old memory back in, 768Mb TwinMos at 2.5-3-3-7-2T and it's been happy as.

Are the memory errors likely to be solely down to the memory? It's the fact that there are no errors at a slower speed which is confusing me.

Any help appreciated!

Full Spec:
4400+ (normally ~30C so it's not temps)
DFI SLi-D
Corsair 3200C2PT
7900GTX
Wireless NIC
Audigy 4
74G Raptor

What BIOS version of the mobo and what voltage are you using for the RAM?

Every time new bios is released they nearly always add ram compatibility. Make sure you have the latest bios. Also as you have dfi try using the other dimm slots and see if that helps. This allowed me to run stable at 270 rather than 250 with a set of corsair sticks on an asus premium motherboard. Generally orange slots are for tccd ram sticks (what you have) and yellow for winbond ram.

Its possible that your sticks are faulty. Try the above first and make sure you have 2.75v through them. If that still fails then try one at a time and see if problem still exists on one stick - then you know they are faulty.

I have the same ram sticks on a dfi expert and they are stable at 2,3,2,5, 1t at 207mhz (havent tested any higher) with only 2.6v. I may have just got lucky but most people seem to get the same with these sticks

I've been testing tonight and so far extra voltage, testing 1 stick at a time, different slots and single/dual channel make no difference, all have resulted in memtest errors (on different tests/passes) and unstability.

The BIOS version is the default the board came with. I'm off to dl the latest one now and see if it makes any difference.

edit:
New BIOS in, im off to stick the memory back in and memtest the fudge out of it

Still got shhhhhhhhed loads of memtest errors. This crappy corsair is going back for an RMA. Never touching their memory ever again.

Can any one recommend a good substitute that definately works with an SLI-D?

Afaik the 2Gb C2PT stuff is Infineon Die Rev B... wasn't aware any of it used TCCD?

Sounds like you have tried everything to no avail. Maybe the RAM was just faulty! Wouldn't blame Corsair though, it can happen with any manufacturer.

What PSU are you using?

GravyMonster · 19 Apr 2006 at 10:57

You're right Sumanji, i know it can happen to any manufacturer, i just needed someone to blame for keeping me up till stupid o'clock for most of the weekend trying to fix the problem

Dutch Guy - the PSU is a Hiper 580w

I've requested the RMA now, so it's going back. Thanks for the help all.

Didnt realise that. I thought it was tccd so have used it in orange slots on my dfi. Works ok though
