pc3200 performance series VS pc4000 regular

[gotensan01]

When overclocking, does a performance stick of pc3200 (xms, hyperx) perform better than a regular stick of pc4000 (value select, valueRAM)? Assum everything else constant and stock running speed of the memory in the system is ddr400 (pc3200). I would imagine the pc4000 would be better but some input would be good.

Also, are lower latency performance sticks good for overclocking? Or do they get unstable because of their small timings?

Should this have been placed in Overclocking?

I would say that at the same speed and timings you will most likely see a slight edge with the xms vs value ram
I have both pc3200 and pc3500 dimms and the performance difference at the same speed is negligible.
as for low latency ram the lower the latency the higher the quality and therefore the more overclock you can get, if a dimm will do 200 at cas2 it will be more likely to do 225 at cas3 vs starting out at cas3 already at 200. there is a difference and lower latency is always better

Cool, since I am new to overclocking (and haven't gotten it to successfully work :|) I was trying to intuitively step through the reasoning behind low latency for overclocking. You explanation is definetly intuitively reasonable and sounds correct to me.

I think I'm just going to have to get some performance series, extra low latency, pc4000 sticcks 😀

You don't have to run the CPU and memory syncronous you can set up a divider and run the ram at say 200 mhz while the CPU is at a 267 FSB thats what I'm doing right now with my value ram.

Yeah, I tried this once and windows wouldn't boot. I stopped trying any more because I didn't want my hdd wiping clean.
