Spi_32m break 10min with ONLY 5Ghz, fastest 32m perclk ^_^

Great speed for that setup, keep it up :clap:

Many Japanese benchers used the 2:3 on i975X since the early Conroe days. Even with the memory in the mid-550 range, it's still extremely fast.

And if it were just Asus' fault, wouldn't we see more 4:5 clocking on other boards? ;)

is this win xp or 2003 ?

clearly Anus needs to address the clocking limitation on 4:5 ratio to match the clocks on other ratios for high FSB benchmarking

More proof that 4:5 divider on P5B Deluxe is alot tighter wound than 2:3. Only ~2 seconds faster with 11x372FSB and 2:3 for 558mhz 4-4-4-4 memory clocks vs 10x409FSB 4:5 511mhz 4-4-4-4 mem clocks.

4091.3 x 738.172s = 3,020,083.104
4092 x 736.282s = 3,012,865.944

To hit 558mhz on 4:5 divider you'd need 446FSB .. now stock P5B DX boot up at 446FSB would be slower due to strap change, and from what most users like Bachus and I have experienced stock max vMCH on P5B DX only allows clockgen from 400FSB to around 432-440FSB. So you'd need vMCH volt mod for 4:5 to hit 558mhz memory.

Congrats:p: 到XS 来日一下V.W :toast:

4:5 on p5b is really hard to run but sure it's faster perclk than 2:3 < 1200mhz.

Congrats, your pi clock very good. Usually good job from you.:toast:

it may be the case but the problem is that it just doesn't clock high enough to be able to be the real contender......my Hz sticks do 543Mhz 4-4-4-x 2.4v on 2:3 and sub 480MHz on 4:5.....even if 2:3 takes it out by a handful of seconds it's still faster overall

but i would like to see you use that same RAM with 4:5 divider and same timings on Max RAM mhz and see what the efficiency is per clock....i bet you it will be slower than 2:3 ratio
