Abit KR7A-Raid Troubles :(

[Amraar]

I just built a KR7A-Raid , it worked great with 256 mb ram , than i installed a second 256 mb stick, and it started acting weird.Random lockups,programs would not run.It boots up fine until it gets to Windows (WinME) I tried moving the ram to a different slot, same result.Tried different ram,from different company.As soon as i take out the second stick it runs fine.Is there any way i could use more than 256mb ram?
thanks

Are the sticks the same manufacturer? Same speeds?

I've read that PC1600 and PC2100 don't mix.

Try slots 3+4.

Also try upping the RAM voltage one notch. If that doesn't work, back down on the memory timings, don't make them so aggressive.

Same PC 2100 sticks, 2 from one company, 2 from another.256mb each.

Do you have it set at 100mz or 133mz in bios, I also read that setting it at 1T in DDR can help.
I have 2 sticks of Crucial pc 2100 and have not had a problem in mine since i det it at 1T

Check the manual but I think to use all 4 slots the memory needs to be registered DDR sticks. Of course that does not explain why it does not like your when using 2 or 3 slots.

Try to run the RAM individually to ascertain that they work first.

BTW is it 4 sticks or two sticks?

Maybe a good idea(if its two sticks only) to use slots 1 and 4...Thats how i did it with my AK31

Hope that helps!

Tried all combinations, slot:0-1 , 1-2 , 2-3 ,0-3 ... tried setting 512 mb limit in windows ME , in msconfig, all four sticks works fine, individually placed, but when more than 1 stick is in there, it starts acting up.Bios settings are on the safe side,it boots fine no problem, only acting weird in windowsME.Thanks for the help anyway.

I would experiment with the ram timmings and see what it will do for you.
I have crucial pc 2100 and can use any slot.
