The highest I could go was 467x9, and I just managed to get a
CPU-Z validation file from it...typically, the
CPU-Z website has disappeared
Going for highest
FSB possible, I tried 510x6 - this was doable on my P5K Deluxe...no go on the Maximus, in fact, I cant even
post with 500xanything, and also, 490x7 wouldn't even boot - (
Fixed with BIOS 0505, highest bootable FSB is now 480, but not stable, see further down the page.)
The problem here seems to be the flakey
BIOS. With my previously stable settings, I restarted and the PC didn't
post, this is also reminiscent of the Commando, with the error on the
LCD Poster showing a random selection of errors from DET-
DRAM (which often means dead
RAM) to
CPU-DET.

Continued...
I have been testing some more this afternoon, and I'm quite concerned about the Maximus now, or at least mine.
Aside from the flakey
BIOS I mentioned earlier, I have been having
RAM problems, in so much as, I have been unable to get stable with anything other than 5-5-5-15. Now the worrying thing is that the Maximus over volts the
RAM by around 0.8v, and earlier this afternoon, the board wouldn't restart without physically unplugging the
PSU. Again, these are exactly the same symptoms as on the Commando when it went on it's
RAM killing spree, not once, but three times, and you can imagine that I wasn't too pleased when my first set of Ballistix suddenly died (
** UPDATE 17-10-07:
This also appears to be a weird BIOS problem with one particular set of Ballistix, as they work in the P5K Deluxe!, so they are not dead.).
I have replaced the ballistix with another set, and I am still having some strange issues.
One issue is that even with 11 hours stable settings, a restart to change some
BIOS settings, results in no
post, and the
PSU has to be unplugged, or turned off and on for a few seconds before it will
post.
I tried a different
PSU - different brand, a Seasonic S12 and the same thing happens.
I am going to try a few other things and I'll report back with any findings....
Flashed back to the 04
BIOS, slightly better, but still cant restart without it hanging at any settings.
RAM clocking is a bit better with this
BIOS as well.

Messing with the Dividers.
Previously, I wasnt able to even

BIOS 0401, they are working.

One other interesting thing that I've noticed, is that, even through all the heaviest of testing, with quite high voltage (1.65v at times), the HR-09 heatsinks were cool to the touch, in fact, so much so, that I took them off to check they were making contact and they were. On my P5K, these got very hot, especially the one on the left of the
CPU, that one got seriously hot, too hot to touch, so this is a great step forward as there will be less heat to get rid of in your case.
Testing 4x1GiB PC2-8500 Crucial Ballistix.

This is where I changed to
BIOS 0505 and things started to get better. Vdroop is much less, and things overall seem to need less voltage, but for the following tests, I needed a lot of voltage to the Northbridge, as you can see from the pics. I did manage to reduce the
NB voltage down quite a lot, but this depends highly on how many sticks of
RAM you are running, how fast you are running them, and how tight the timings are. For most people, running 4x1GiB @ 800Mhz, or even 1066Mhz with reasonable timings, then a couple of extra notches of voltage to the
NB should be sufficient.

Highest FSB.
The Highest bootable (not stable)
FSB I can hit with this board is 480, as opposed to 510FSB on the P5K Deluxe, hopefully this will change as the
BIOS matures.
