qbitzer Posted January 5, 2006 Share Posted January 5, 2006 I just purchased twinx 2048 xms3200 c2pt modules for my Asus P4P800 and am having problems. I have tried everything I can think of, but I can not get these modules to run at the rated 2-3-3-6 at stock DDR 400 speed. The tests cause massive memtest+ (v1.65) errors after 10 min (end test 5 or start of test 6, at 2047). However, they run fine at 2.5-3-3-6 all the way up to DDR 450 (225) (run memtest+ and prime 95 for hours OK). Then, they fail Memtest+ at 230 and these timmings. The module info is: Twinx2048 CMX1024-3200C2PT XMX3202v2.2 0552009-2 (which IC please?) This board was previously running twinx 1024 xms3200 c2pt @ 2-3-3-6 (although when purchased these were rated at 2-3-2-6, they would never run at that speed). I was running these at 2.75 volts, PAM = standard, MAM = auto I have tried all other combos of PAM and MAM, and RAM Idle Timer and refresh rate of Auto/Auto and Infinite/7.8., and have adjusted voltage to 2.85. I am planning to use this memory in this board for now in this board and later switch it to a new A8N32 or DFI Expert SLI board based system. Shouldn't this memory conform to 2-3-3-6 spec in this board like the 512 modules (CH5) did? Or are these 1024 modules pickier? :confused: Does the fact that I can (only)go up to 225 at 2.5-3-3-6 further confirm the modules aren't up to snuff, or is that just what would be expected at these speeds? Pertinent info: Bios ver 1010. Power supply Antec true Power 400, P4 2.8c at stock speeds. Legacy USB is off, Spread spectrum is off and ICH5 delay Trans is enabled.
