xms4400 problem


Fraggle99

Recommended Posts

Hello, I recently purchased two memory modules cmx512-4400c25pt from a local computer shop and I`m having trouble getting one of them to work properly. It only boots windows up to 230Mhz and won`t even post above that. Even when it boots at 230Mhz it fails Prime95 after 10s and dual channel operation is out of the question :o( The other module works flawlessly alone at 275Mhz. My timings are 2.5-4-4-8 command rate 2. Is it faulty?

The HT multiplier is set to `200Mhz`, 1:1 in other words. Even with the cpu at 250x8 (well below stock) I get the same trouble but only with the one module. I`m fairly confident that the settings are good as one seems to work perfectly alone running p95 all night long at 275Mhz (275x12@1.6v, 275Mhz HT, 2.5-4-4-8, 2T).

Thats correct but there should be a HTT multiplier and the HTT Freq will always match the CPU Freq. but the total HTT Freq cannnot go over about 100 MHz max so the HTT multiplier needs to be lowered to O.C. the system.
