RichardG Posted April 26, 2005 Share Posted April 26, 2005 There's a bit of a back story to this one, so please bare with me. :) Purchased 1GB of Corsair TWINX about 2 years ago (TWINX1024-3200LL) and it ran perfectly stable for about the first 12 months in a revision 1.2 Asus A7N8X Deluxe with a AMD 2800+ chip. After that time I started noticing random bluescreens which progressively got worse. I tried multiple clean installs of Windows XP - Which didn't work, as well as updating drivers, changing BIOS settings and finally updating the BIOS firmware. Nothing helped. On checking my minidump files from XP I noticed that all of the crashes were related to memory corruption, which I was advised could potentially be because of a faulty motherboard. I ran a bunch of tests and couldn't seem to get the memory to fail so I replaced the motherboard, processor and PSU. My new motherboard is a MSI Neo 2 Platinum (Version 1) and the chip is an AMD64 3500+ (Interestingly enough this is a similar set-up to the post here: http://www.houseofhelp.com/forums/showthread.php?t=37954 ). However, putting the memory into this new set-up instantly causes random bluescreens. I've tried it with 512MB of corsair and 1GB of XXXXXX ram and it works flawlessly (More than 2 weeks and as yet not a single crash). I also tried my old motherboard and chip with this different memory and it runs perfectly stable. I've tried running the memory timings by SPD (I think that's the right term) and also manually entering the timings using the values stated 2-3-2-6 (1T) on the Corsair website. I've only seen the ram fail memtest on one occasion, where it repeatedly failed test 7. I have been unable to recreate this. Information written on the parts: CMX512 3200LL 2226-T1 XMS 3205 v1.1 0306034 Thanks in advance. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted April 26, 2005 Corsair Employee Share Posted April 26, 2005 Please make sure that you have the latest bios and then load setup defaults and set the following settings and test the modules one at a time with http://www.memtest.org and lets make sure one is not failing!

RichardG Posted April 26, 2005 Author Share Posted April 26, 2005 A lot of those options aren't in my BIOS but I've used them as applicable. Can you suggest how long to run each module for? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted April 26, 2005 Corsair Employee Share Posted April 26, 2005 3-4 passes should be enough to show a weak or failing module. Link to comment Share on other sites More sharing options...
RichardG Posted April 26, 2005 Author Share Posted April 26, 2005 Tested both in two machines, individually and together for 4 passes - No errors. Tried windows with your recommended settings; bluescreened within half an hour of getting to the desktop. :(: Link to comment Share on other sites More sharing options...
RichardG Posted April 27, 2005 Author Share Posted April 27, 2005 Bump - Any advice? I appreciate that memtest isn't showing errors, but I'm seeing a very clear correlation between the ram and bluescreens on whatever PC I put it in. Link to comment Share on other sites More sharing options...

RichardG Posted May 31, 2005 Author Share Posted May 31, 2005 I've had it running for 5 days now with no bluescreens so I think we can assume that the problem is fixed. :biggrin: Thanks for your assistance. Link to comment Share on other sites More sharing options...
