Part number on all the sticks is VS512MB400. For some reason, #2 has a second timing table but they all have a compatible one for 400mhz... but I can't make it boot showing higher than 333mhz. Board is an Asus K8N with an AMD Athlon XP 64 3100+ Ive tried configuring the memory to auto in BIOS, and it goes to 200mhz. When I set the clock, CAS# Latency, RAS# to CAS# and RAS# precharge to 200mhz, 2.5, 3, 3, 8 respectively, it only shows 333. Why is that? Heres the weird part: Without the third stick in there it will do 400mhz
Have you got four slots? Try and run only two in slots 1 and 3. Then try and run two in slots 1 and 2. Maybe the whole thing has something to do with the Dual Channel operation?
For some reason, sticks 1 &2 will operate in any DIMM at 400mhz. Sticks 1 & 3 or 2 & 3 will clock down to 333 though. Something about the third stick somehow, even though its identical to #1. I have another stick of Kingston KVR400 512mb, and a stick of Adata 400mhz 512mb and I can not combine any of the 3 to get 400mhz. These is all single channel memory DDR400
multiple single channel RAM automatically becomes dual channel when they are installed with other single channel RAM in a mobo that supports dual channel RAM BTW: sorry, i should have added that onto my previous post
