Will PC2700 help my system post?

I'm currently using pc2100 DDR memory (system is in sig)
and if I set my memory timing to ULTRA/2/5T/2T my system won't
post.

If I relax the settings a bit to ultra/2.5/6T/2T my system posts and runs as it should.

Will replacing my pc2100 memory w/ mushkin pc3000 or samsung pc2700 memory help my system to post at more aggressive memory settings?

Thanks in advance.

It very well could, the 2100 is only ment to run at 100mhz, so running it that far out of spec is going to start to drag it down. But the other run faster, so will be less out of spec.

it will greatly, maybe even a better overclock.

pc2100 = 133 FSB while pc1600= 100 FSB just to clear that
up

Oh, Oh yeah must have gotten my ddr stuff messed up, was thinking that was a good OC for the mem.
