It was the new BIOS. The M2F has 2 BIOS chips, and you can save different BIOS versions to each one and have settings saved corresponding to each BIOS, and you can choose which BIOS you want to boot from (I think the Rampage Extreme has the same thing). I was previously using BIOS 1307, which was solid but the 1:2 divider never worked and it didn't want to clock ram past 666 MHz regardless of divider used.

2 test with my best cellshock pc8000 kit and my ud3r
PL10

PL9


i've made these test just to compare my board with my mates ones: m2f, dfi dk p45 and p45 extreme with fixed configuration: 550fsb, strap 333/5:6, cas5
dunno why ud3 serie has this problems with PL (can't boot @ 400fsb with PL lower than 8...)

Yup RE has same dual bios comes in handy although I have yet to use it heh

nice... probably why UD3 has higher FSB due to some tweaks with higher PL capable but not lower PL ?

maybe you're right eva
but if so, dfi dk p45 is really uber, with low PL and high fsb, almost same of ud3

Yes the UD3P/R seem to be stabilizable at higher FSB/ram speeds than the M2F, but they perform worse clock for clock. The DK/UT P45's are very efficient for the platform, better than other P45 boards.

My board at the same settings but tRD8 from the first page.

550 FSB, 3.85GHz, 660 MHz CL 5, tRD 8

Some SPI32M runs would be a much better comparison between the 2 boards as everest is just synthetic, but the M2F has a little better bandwidth at identical settings from what I remember of previous comparisons. I'll do a PL9 run when I get the chance but I'd guess it would be around 10800 - 10900 read, same write, 11400 copy and around 49ns latency.

Are you sure you are giving the board enough vNB to boot at high FSB and PL8?

Here's a lower PL run on my M2F.

434 FSB, 3.9GHz, 651 MHz, CL 5, tRD 6

Here's my CellShock 8000 C4 sticks at their 24/7 settings.

600 MHz / 5-5-5-15 @ 1.97v / 500% dual HCI Memtest
