The 2 HyperX PC3500 512MB sticks I got seem to suck big time. I'm trying to use them on my Abit NF7-S V2.0. I actually had 2x512MB Kingston HyperX PC3000 in there, working pretty much flawless at spec at 370MHz, 6-2-2-2. I tried the PC3500 at recommended 434MHz, 7-3-3-2. Memtest-86 reports errors in Test 5. Tried 9-4-4-3 (which sucks wrt. speed), still errors. Tried lowering speed to 400MHz, still errors in Test 5. Tested one stick at a time, both have errors, one stick less than the other. WTF?
The PC3000 never had such issues, works perfectly. BB better take this back, I am pissed. I guess with the HyperX, it's a crapshoot, you either get good stuff, or crap. Oh well.
