I currently bought Gigabyte GA-8KNXP, with 800FSB 3G Petium 4, this motherboard supports 4 Dimms at max of 4G, so i have filled them up with four Twinmos DDR400 512 MB (running in dual ch). after that, system is not stable at all.
I have tried run DOCMEM memory diagnostic, but it freezes when attempted to test memory. so i removed 2 sticks of memory. system now left with 1024MB, then the memory diagnostic runs without any problem. i have changed the 2 sticks with the one i removed, again, it runs with no problem at all.
Is this a compatability issue between memory and motherboard?
because there is no problem with memory, only when 4 of them run together problem occurs.
perhaps better quality memory can cure this problem??
p.s. i have run seagate diagnostic on harddrive, harddrive have no problems.
