i have 4 sticks of 2gb ram each - all quality ram by OCZ and Corsair.

when i put in all 4 sticks, i get memory errors

when i put in 3 sticks, no errors

but the thing is - i tested with the last 2 memory sticks. i can swap the slot and still not get memory errors (i.e. have 3 sticks in slots 1,2,3 or 1,2,4) and i can swap out the sticks as well and still not get errors (i.e. have sticks 1,2,3 being used or sticks 1,2,4) so it's not the slot and it's not the RAM (i even got the OCZ RAM RMA'ed once because I thought it was their RAM).

could my motherboard be messing up when in dual channel mode and is there any way to disable that or should i just use 6gb?

are you supposed to be mixing types of memory?

i thought they had to be the same

What mobo do you have?

Are the sticks rated the same for timings and voltage? If they are have you tried to relax the timings? Have you tried to give the ram 0.05v or 0.1v over the recommended voltage? Some cheaper motherboards cant keep timings or supply consistent voltage to 8 gigs of ram.

Also you havent said how you know it has memory errors. Are you running memtest and it tells you there are errors. Or are you blue screening, or not booting or freezing after booting. That may help in the diagnosis.

^what he said

though it could be a remote possibility that one of your slots is bad, but i'd test all the other alternatives with voltages/timings/memtest first

i have an asus p5q pro

i have these sticks:
slots 1 and 2: http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=10008006&prodlist=celebros
manufacturer: http://corsair.com/products/dominator.aspx (TWIN2X2048-8500C5DF)
specs PDF: http://corsair.com/products/go.aspx?pn=TWIN2X2048-8500C5DF
2.2V and 5-5-5-15-2T

slots 3 and 4: http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=10008035&prodlist=celebros
manufacturer site: http://www.ocztechnology.com/products/memory/ocz_ddr2_pc2_8500_reaper_hpc_4gb_edition
2.1-2.2V and 5-5-5-18

so if the last number on the timings matters, they're not exactly the same.

i will try giving it more voltage in increments and testing again

yes, i have been using memtest. and i can tell now when using windows as well - unRARing stuff fails, etc. all bad CRCs and things - the signs are the same as they were before.

memtest gave no errors after 20 minutes of running - that was a good sign

so then i loaded up call of duty 4 and started playing

after a while, i had a weird blue screen that i've never seen before - win32k.sys

i upped the voltage to 2.22 instead of 2.2 and i'll see how that works. it seems to have fixed the problem to go with the slower 5-5-5-18 timings and tell it how much voltage is needed, but more experimenting with this will tell if it really worked.

thanks though
