What I would do is test each DIMM in the first DIMM slot (is it listed as 0 or 1? I don't remember with RAM...). As long as each DIMM tests okay in that one slot, you know that slot is good.
Next, as long as each DIMM tests okay, I'd take one DIMM and test it in the next DIMM slot (still only using one DIMM at a time). As long as that DIMM passes, move on to the third, and if that one passes, move onto the fourth.
If all four DIMM slots work okay being populated singly, next step is to populate them in pairs; start off with the first "Dual-Channel" set (1 & 3, IIRC) and test them. If they pass, add one to DIMM slot 2. If it passes, add the fouth. If it doesn't pass here, yank out DIMM 2 and see how 1, 3, and 4 run together.

I know, there might be a lot to it, but this is the route I'd try to isolate them.

Good luck!
Ok, thanks alot for that info, i'll give it a try today..

its winXP pro sp2 32bit, and yeh i understand that 32bit doesnt support 4gb memory, the problem is that this is all being tested in dos (memtest)

second: you need to up the vdimm to about 2.25 to 2.3v

third: change your dram timming to 5-5-5-18(tRAS..or higher) and "tRC" to 42(or higher)

fourth: mch needs to be at 1.4x voltage minimum.
ok i will try those settings today, thanks alot guys
