P5B-E Asus motherboard...looking for optimal settings for DDR2-800 ram

[Hammer67]

Hi there,

I have a P5B-E motherboard from Asus with the latest BIOS (v1101) and an E6400. I overclocked the FSB to 333. See pic:



This is the RAM I have:

Brand G.SKILL
Model F2-6400CL4D-1GBPK
Type 240-Pin DDR2 SDRAM
Capacity 1GB (2 x 512MB)
Speed DDR2 800 (PC2 6400)
Cas Latency 4
Timing 4-4-4-12
Voltage 1.9V - 2.0V


The issue I am having is that I can get the memory to boot at PC-5300 at 4-4-4-12 but not at PC-6400. Is there a way to do this with this ram and still overclock the BUS for the processor? I currently have the voltage at 2.1v.

Or, would I get better timings at 5-5-5-15 at PC-6400?

Thanks a ton. BTW, all the rest of the ASUS timing settings are default aside from the main four above.

Here are the other screen shots from my CPU-Z readout:








THANKS!!!
