Memory timings on the A64?

[TrueWisdom]

Hey all--I've got a GB (512x2) of OCZ Gold PC3700 RAM running with an A64 Venice 3000+ on a DFI Ultra-D board. I overclocked a good long time ago (when the Venice was first released) and am running perfectly stable at 2.4 GHz on the CPU--however, I've had to absolutely destroy my memory timings. I'm running at 200 MHz, 2.5-3-3-7 2T, at memory that is rated for much higher clocks at the same latency. Does anyone have a similar setup running that could help me figure out why I can't boot stable at any timings or clock speeds greater than this? Is there a setting that I'm missing?

EDIT: Would the power supply affect this? I am (I know, shame on me, but I was poor after upgrading) still running off of an Antec 480 TruePower, that does not have dual rails for the CPU. Would getting a true 24-pin PSU solve this problem, do you think?

Bump?

Why the low timings, especially the 1T?
As you run the memory @200/PC3200 i.e. under its spec you should be able to tight the timings in the BIOS to maybe 2-2-2-5-1T. As it is OCZ, you can also bump the voltage quite a bit to get it stable...

I can't get it to boot stably at any speeds higher than what I listed. if I do so, the system hangs at BIOS, or I get a BSOD when I get into Windows. It doesn't make any sense--I can't figure out what the issue could be, besides a bum memory controller on my A64.

Are you running the memory at 200mhz, or do you have the divider set to 200mhz? Cause if you are overclocking, and have it set to 200mhz in BIOS, then it's running at higher than 200mhz..just thought I'd check..

I have the divider right now at 150 MHz, or 3:4, which puts me right at 200 MHz for the RAM. (202.5 to be exact)
