Tnemec Posted December 5, 2006 Share Posted December 5, 2006 I went through the guide but i still dont get it. I have a Asus A8N SLI SE and currently use: Bank A1: CMX512-3200C2 (v5.2) Bank B1: CMX512-3200C2 (v1.2) Bank A2: CMX512-3200C2 (v5.2) Bank B2: CMX256A-3200C2 (v1.1) at first i had lots of instability issues but then i raised the DRAM Voltage to 2,7V as i read in one of the posts here... now the system is up and running but when under heavy load it freezes after a couple of hours or sometimes even in a matter of minutes. i read that the modules should be matched exactly so i took out the 256mb stick, but no luck, still the same issues. the whole system is well ventilated and i have excellent temperatures. the timings are set on "by SPD". the automatic overclock features etc. in the bios have been disabled.

Tnemec Posted December 5, 2006 Author Share Posted December 5, 2006 well i seem to have fixed the problem by removing the sticks from bank B1 and bank B2... i will now try if the problem is persistent when adding the 512mb (cmx512-3200c2) stick back in. i mean it should work as it is the exact same model of corsair xms ram, or not? they are all corsair, all pc400 and all cl2 after all... or do the version numbers on the sticks mean i have to have identical version numbers (e.g. v5.2) like on my twin sticks to get them to work together? i'm confused :confused: because when that is the case i can not even buy another cmx512-3200c2 to compensate for the now missing 256mb stick?

Corsair Employees RAM GUY Posted December 5, 2006 Corsair Employees Share Posted December 5, 2006 I am sorry but I would not suggest mixing memory with this MB! All of the modules would need to be exactly matched both in part# and revision! Link to comment Share on other sites More sharing options...
Tnemec Posted December 5, 2006 Author Share Posted December 5, 2006 well thanks for the fast response. i would appreciate if you could answer me a few questions. is it just this MB or generally ASUS mainboards? (as most of the people with compatibility issues have an ASUS MB) can you suggest a few socket 939 mainboards where i could mix different module revisions? and what timings can i run my modules at on that board when using the two CMX512-3200C2 (v5.2) in dual channel at pc400? thanks in advance, Tnemec Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 5, 2006 Corsair Employees Share Posted December 5, 2006 No its the platform not the make of MB. The memory controller is in the CPU with AMD 64 based systems and the reason you should not; could not; might not work. Link to comment Share on other sites More sharing options...
Tnemec Posted December 5, 2006 Author Share Posted December 5, 2006 so on a regular athlon xp system you could mix module revisions? suggesting that the motherboard memory controller supports it right? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 5, 2006 Corsair Employees Share Posted December 5, 2006 Not always, but the make and model of MB and PSU will have an impact in mixing memory! However, I would never suggest it on any system for best performance! Link to comment Share on other sites More sharing options...
