Problems with RAM Timings

Recommended Posts

I recently put together a machine with 2gb of Corsair ram, model TWINX2048-3200C2. The CPU is an AMD 64 X2 4400+. The motherboard is an Asus A8N32-SLI Deluxe.


I specified the timings in the BIOS according to how Corsair tested the ram. 2-3-3-6, with the DDR vcore set at 2.75v. Everything else is default.


It booted fine, but Prime 95 gives errors.


So I tried 2.8v. Same problem.


So now I've backed it off to 2.5 CAS. Now I am running Prime95 twice, one instance assigned to each core. I've not received errors so far. I've read on this forum that AMD was reccomended 2.5 CAS and Intel 2. Then I've read that Corsair now approved CAS 2 for both types.


Is there something wrong with my ram that I should look into RMA? Should I be concerned about this (other than the fact I can't seem to hit tested settings)?


Sorry if I posted this in the wrong place.

Please set the Dim Voltage to 2.7X volts (+.2 Volts W/Giga-Byte) and then set the timings manually to the tested settings for the specific module you have, XMS2700C2 Cass 2-3-3-6 for example or if you have Value Select "BY SPD" and then test the module/'s one at a time with www.memtest.org! If you still get errors, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure.

Thanks for replying. Do you feel that memtest in this case is a more appropriate test?


I currently have it at 2.5-3-3-6 1T, stable without errors, running Prime95 for 24 hours. I was already running at 2.75v.


I'll try one stick at a time. What do you feel is an appropriate length of time to test each module?
