Purchased 2*512mb (pc3200 dual channel and the the motherb does accept them) legend ram sticks. i tested them using a boot program and they checked out ok after 12 hours testing. But i have been getting random crashes, full resets and just general game crashes. These happen most frequently when playing games. I have tried the ram on 2 computers and they have both had the same errors. Yet they both still work fine when using my old 256* 2 ddr133 ram. I also get the same problems when only using 1 of the 512 sticks. So i figured the ram must have been at fault in some way which only occurs under high loads or in windows. overheating maybe. so i bought another dual channel kit twinmos same specs as the other stuff. However i have been having exactly the same problems sice installing this. I tried turning the ram timings down to 50% speed and it was running fine for about 2 days then suddenly it starts crashing again. Please help me this has been goin on for about 6 months now and its got me stumped.
