ok, I'm using Mushkin Enhanced PC3500 DDR433,... 2-3-3 rated timings (running at 2-3-3-6). I loosened up the timings to 2-4-4-8, and ran at DDR464. I then tried 3-4-4-8. It didn't seem to make a difference. I still got errors running SuperPi (I don't bother with memtest unless it passes SuperPi, I'm lazy
) I can relax the timings all the way, and max the voltage, and the stick will still not run at DDR464 without errors halfway thru the 1M, if I'm lucky. Weirder yet, I have managed to run it at 2-2-2-6 @ DDR436, boot into Windows and start having errors in 1M, after having a BSOD the first time around, and upping the voltage to 2.8. That was a couple of weeks ago. Today, I thought I'd have fun, I put it on at those timings, at stock system speed (DDR400), BSOD the first boot, and registry error the second time, which freaked me out so I changed it back to normal in a hurry. I ended up having to reinstall some corrupted software.
1T versus 2T did not seem to make a difference. I leave it at 1T. I think I actually had a harder time passing tests in SuperPi with 2T. :?
oh yeah, and this is a P4 3.0Ghz rig with that crappy Jetway mobo :roll:
Also when I was overclocking my Corsair ValueSelect (which I actually got thru a 1M test once, at DDR464), CAS latency didn't seem to make a difference. 2.5 versus 3.
Of course, I"m not sure that any of that doesn't make a difference, it probably does, but I failed to notice much, probably do to the poor memory sticks I got. I'm looking for some RAM with BH5 or CH or UTT IC's now, but I don't even know what that means, so if you can explain the difference and what they do and how they perform, that would be greatly appreciated.
