I've heard good stuff about crucial value, but I guess ballistix is better. Though, if you're on the A64 platform, you are aware that getting faster memory won't improve your performance much, right? Since you already have decent memory, I'd say stick with what you have. If you want something that overclocks well for benchmarks (and as a "toy"), just buy a good 2x512 kit, depending on what your mobo is.
My suggestion would be just to get the crucial, ram doesn't matter much (assuming you're on the A64)
oh, you want some TCCD then. Or ballistix. Though, I'd make sure the chip OC's as reported before shelling out a ton of cash for ram, not sure how you'd do it though. Just because that's a really high OC, and I saw the screen in another thread, the RPM fan at zero seems a little suspect, but the really sketchy thing is the lack of a stability test in the background. Anyone can boot a chip at a high speed, running it stable is another thing. Did he say what program it was stable under, and for how long?
If the CPU is unlocked, can't you just raise the multiplier higher? Or is the max multi X 250 the lowest bus you can reach the OC with?
Because if this system does not overclock well. I am going to sell my two P4's and go AMD X2. So the DDR will be used in that system. Or I can just sell it on EBay. The ram I got from Crucial was $399.00 for the 2Gb kit. The same ram on EBay is selling for $230.00 for each 1GB stick. I just hope my P4 will overclock in the mid 4Ghz with watercooling and this ram. We will see.
