Testing overclocked memory

I'm using 256MB of PC2100 K-byte CAS2.5 and I'm trying to overclock it. It hasn't had any memtest problems for 15 hours at 148MHz, so I decide to increase the timings to 2-2-2-5 from 2.5-3-3-6. To my surprise, no errors come up. What I would like to know is if the timings affect Memtest's tests (does increasing the CAS usually bring up errors if there's a problem)? And if there is another program that I should use to test the overclocked ram (something that doesn't need an OS to work)?

Yes, and no.. unless you wanna buy a very expensive DIMM tester. There's always docmem, but that's basically the same thing as memtest.

Hmm...so if there weren't any errors with memtest I can trust running the ram at CAS2 and 148MHz?

in my experience, I get better bandwidth from 2-3-3-6-8-4 way-1T.

in fact, I got about 200mb more than at 2-2-2-5.

hmm. almost no relation to the question, but hey, some helpful info nonetheless.

Yeah... tho I've found in practice sometimes I need to run it a mhz or 2 lower than it's max tested memtest speed. Best games I've found to test real world stability from a CPU/Memory standpoint are any games based off the unreal engine.

Well Windows' registry got corrupted even though it was passing all the prime95 tests at 148MHz. I don't have any unreal based games so I can't really test its real world stability. I guess I'll just lower it by a few MHz.
