jaysie Posted October 20, 2006 Share Posted October 20, 2006 Hello I've recently bought a second ram: CMX512-3200 C2 PT XMS3202v1.1 023632 I have a first one with the same naming, maybe another version and the number below is probably different, running at 400MHz. The one named on top can only be run with 333MHz, why that? I tried many things to get it to run, like using another memory row or resetting the BIOS. I even tried to enforce 400MHz with Timings of 2.5-3-3-8. But than the compoter didn't start and I had to clear the CMOS. So what might be the problem??

Corsair Employees RAM GUY Posted October 20, 2006 Corsair Employees Share Posted October 20, 2006 You cannot mix memory with the MB you have listed in your signature; both modules would need to be the exact same part# and revision. The module you have just purchased "CMX512-3200 C2 PT XMS3202v1.1 023632 was made in 2002 before the JEDEC spec was ratified for DDR400 and the modules SPD is set the PC-2700 spec. but you should be able to manually configure the MB bios to run the module at its tested setting and frequency as long as you have a 200 FSB COU.

jaysie Posted October 21, 2006 Author Share Posted October 21, 2006 I already tried to do so; using only the Ram just bought; but if I set manually the Frequency to 400MHz the Computer just didn't start up and I had to clear the CMOS by removing the battery.

Corsair Employees RAM GUY Posted October 23, 2006 Corsair Employees Share Posted October 23, 2006 What slots do you have them in and have you tested the modules one at a time? Link to comment Share on other sites More sharing options...
