imotic Posted October 27, 2006 Share Posted October 27, 2006 sorry for the crosspost, but i haven't received a response in the compatibility questions forum and i'm not sure which forum is the right place. i've had some Corsair RAM for a little more than 2 years now, never had much of a problem. a few days ago, i bought some new processors, and bam, i'm having RAM issues, and i can't figure it out. do i need to buy new RAM? do i need to change my BIOS settings? i've tried running memtest, and when I have ECC turned on, it reboots immediately. when i have it turned off, the tests fail pretty quickly (it doesn't seem to get all the way through), and i KNOW that ECC needs to be turned on for this mobo. here are the relevant system specs: MSI K8T Master2 motherboard 2 Opteron 248 processors Corsair XMS 1GB (2 x 512MB) 184-Pin DDR SDRAM DDR 400 (PC 3200) ECC Registered Dual Channel TWINX1024RE-3200LLPT the processors are an upgrade from a single 242 processor. as far as BIOS settings are concerned, everything is pretty standard for these processors, and my motherboard doesn't really give many options. RAM frequency: 200 MHz RAM voltage: auto (i can choose somewhere between 2.5V and 2.65V in 0.05 increments) Chip-Kill ECC mode: enabled DDR timing: auto [CAS latency: 2.0] CPU clock ratio: 11x (standard for these processors) CPU voltage: 1.5V (again, standard) Auto-detect PCI Clock: enabled Spread spectrum: enabled CPU clock: 200 MHz i bought the RAM from Newegg in july of 2004, i'm not sure what my warranty options are, if any; i'm not even convinced that the RAM is bad, but i'm unaware of any kind of compatibility issues here, especially any that would be created by introducing processors that are only a little better than the one i had before. please, any and all suggestions are helpful; i'm also kind of looking for a "final word" by someone smart at Corsair (or anywhere) that can put a definitive stamp on this issue. or ANYBODY who knows more than i do, really.

Corsair Employees RAM GUY Posted October 27, 2006 Corsair Employees Share Posted October 27, 2006 Did you just change to the new CPU's and then have this problem, or did this just happen? Link to comment Share on other sites More sharing options...
imotic Posted October 27, 2006 Author Share Posted October 27, 2006 Did you just change to the new CPU's and then have this problem, or did this just happen? it happened as soon as I installed the new processors. the ram worked fine with the old processor.

Corsair Employees RAM GUY Posted October 28, 2006 Corsair Employees Share Posted October 28, 2006 With the new CPU installed please reset the bios and then load setup defaults and set the settings needed for your specific modules and then test the system with http://www.memtest.org.

This turned ECC off; memtest failed with ECC turned off, and wouldn't even run (computer would reboot) with ECC turned on. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 31, 2006 Corsair Employees Share Posted October 31, 2006 ECC should be enable with these modules, but it should run with out it as well. Let's get them both replaced. Please use the RMA request found in TSXpress or follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! And please note that you are from the forum! Link to comment Share on other sites More sharing options...
