Just wanted to give a thumbs up to this new Cricial Ballistix 2 x 1GB Z503 RAM I just bought. On the DFI Ultra-D this pair are memtest 5 and 8 error free for about 5 hours at 288Mhz 3-3-3-8 @2.8v at which point I stopped the test. I was only expecting 250 - 260 so a nice surprise for a 2GB kit to climb so high
I tried 289 and 290 and started getting a few memtest errors so gave up on that till I read more how to burn in RAM properly
