A long time ago I bought a new D865PERL motherboard (p4 3ghz cpu) with a matched set of Corsair Value Select PC3200 DDR DIMMs (VS512MB400) CL2.5. I put them in staggered slots so they ran in dual channel mode. Later I purchased Kingston PC3200 DDR DIMMs (KVR400/512R) CL3 and installed those in the remaining two staggered slots. All the DIMMs are 512mb. All was seemingly good but after a couple weeks I started noticing really strange things happening: corrupt files, errors copying files, program crashes. Long story short I determined the Kingston modules were bad using memtest. I RMA'd the bad ram (both modules so I would get a matched set back).
I received the new modules and installed them and again after a couple weeks noticed weird things happening. This time memtest reported the Corsair modules were bad. I RMA'd them and put the Kingston modules in Bank 1. I got the new Corsair modules and installed them in Bank 2. Again strange things were happening after a while, so I ran memtest and found the Kingston modules were again screwed. I RMA'd those and haven't tried installing both sets of modules together in a couple years now, but I still have one brand new package of RAM here, and both companies verified their RAM is compatible with this board and the other RAM.
I would like to install all the RAM to bring the system up to 2 gigs after all these years, but obviously either the board can't handle these two types of modules together, or the board can't handle different types of modules in different banks in dual channel mode. I would like to sell the modules and get something that works if I can figure out if the problem is the RAM or the board.
I have ran the board for months on both the Kingston and Corsair modules without issues, so I know each brand/type works by itself in the board. I always had the BIOS settings set to auto. Does anyone have any idea what's going on? Does all the RAM have to have the same cache latency?
