Is your 2100+ o/c'ed above 13.5x166?

Just curious. My AIUHB0304 won't boot in my Asus A7V333 mobo (rev 1016 BIOS, mobo rev 1.04) with any clock setting higher than 13.5 when the FSB is 166MHz.

My temps are stable, 40 degrees C at full load.

I've even tried using 1.80V in the BIOS setup.

Should I manually set the jumpers to a higher rate and see if that works? Or am I stuck at 13.5x166 (2250 MHz, which isn't exactly bad...)

Thanks!

If it will not boot at 14*166, why not try something like 13.5*170 or 13.5*175? Can your RAM and mobo handle a higher FSB speed than 166?

My 0302 is stable at 13x177 (2300MHz) at 1.825v in the bios. (1.88ish on PCProbe). I too have an A7V333, so maybe you're hitting your chip's limit. Burning in may help you get more out of it.

Thanks for the info!

I use Crucial CAS 2.5 PC2700 RAM. Two 512 MB modules.

I tried o/c'ing my system to 170MHz FSB but the system quickly became unstable, even with the most lax RAM timing settings.

Given that my RAM is actually 6 NS, I can run the RAM at 166MHz FSB at the highest timing settings and not experience any corruption.

I'll try burning it in next, to see if that yields any positive results.

Im not sure if im right here, so dont take what im saying to be fact. I know that there is certain reserved multipliers on certain motherboards that dont work to good. 14x could be one? Try 14.5 or just 14 at 133 to test this theory.

Just a thought.

i have an AIUHB 0304. i run it at 12.5 x 200mhz

just bump up the vcore and it should overclock a bit more.
