Nice results man! Cant wait for you to really punish this thing under some LN2 + 3dmark action.
Any idea of the release date on it?

630 validation in windows is promising
looking good there Tim.... i stuck on 600 Mhz FSB with E8500...http://valid.x86-secret.com/show_oc.php?id=380419
The performance level thing is a weird one, when left at Auto memset reports 3, but if i set 3 in BIOS it wont boot.
Yes.. i experience the weird problem on PL... mine shows PL = 1...Originally Posted by T_M
weird
looks like they've done some strange stuff with bios
on biostar P45 memset works fine
have you tried setting to PL that it would work with .... for example at 600MHz FSB you should be able to run PL-9 or looser if chipset is struggling ....with better cooling or chipset PL-8 was not uncommon at such high FSB on P35
Yeah, i tried PL=13 on both DIMMS and it came up as 13 in memset.
But when i booted at Auto, and set 13 in memset it froze....
When i set PL loose i.e from 1 to 3 it's still working, but above 3 it will give BSOD instantly. So..it's really weird, and not impact at all to reach more higher FSB.
maybe it was marijuana day during this bios writing procedure
they do work very hard though
Is there a price tag on this board yet?
Tim can you please report on memory testing you've done so far
CAS5/6/7/8 clocks
Memory testing so far:
8-8-8-20 2T-55:
400fsb
2.00D fine
2.40B fine
3.xxB fine
4.00B fine
420fsb
4.00B fine
430fsb
4.00B fail to POST
have you tried CAS7 and 6
Not yet
Pulled apart the cooling on the board and soldered on some volt read points.
See pictures below.
It appears that leaving PLL set to auto results in huge volts pumping into the CPU PLL when running high FSB, at 560MHz im reading 1.89V.
Turned it down in BIOS to 1.6V set (1.63V reading) and its stable just the same, so it seems too much PLL being set by BIOS at the moment.
Im not a big fan of heatpipe assemblies, so i took an old P35 cooling system, chopped off the heatpipes, and stuck them onto this P45 board
SB heatsink needed slight modification to the mount holes, seems about 1-2mm wider spaced holes than the P35 boards.
DDR2 board read points would be able the same i assume?
can you tell me something
do all the voltages set properly from bios
if you set all the values do they all read similar volts to what you've set in bios
my board refuses to boot past 1.5v NB at high FSB and it requires me to keep my NB volts lower than Termination volts (VTT) which is no good as that would mean that for me to go past 1.5vNB i have to shove around 1.54v VTT and any more volts in NB would result in higher VTT......i'm not going to kill my CPU just to stabilise it at 600MHz FSB
i am also testing a biostar board and they have now unlinked NB and VTT volts and i can select 1.6v NB and 1.35v VTT and be able to get 32M SuperPi stable up to 615MHz FSB with PL10 which is pretty good and fast too
the linking of vtt and nb is a deliberate thing, the biostar engineer told me that the board faces 'instability and risks' if we seperate these voltages too much, so we might need to get gigabyte to do the same thing with their bios
When set on Auto, here's a quick tabulation of what PLL and Termination volts do (measured as above) during OC'ing an E8400:
FSB -- PLL --- Term
333 = 1.570 / 1.211
400 = 1.690 / 1.212
450 = 1.794 / 1.524
490 = 1.894 / 1.525
500 = 1.895 / 1.630
550 = " / "
600 = " / "
620 = " / "
My readpoints for PLL / Term read approx 0.03V higher than BIOS set and what ET6 shows

OMG dude
1.63VTT and 1.89PLL
that is crazy
woah that is crazy seems all P45 are doing some form of auto = high CPU PLL / CPU VTT/FSB volts even Asus P5Q series from what I read...
If it's an intel spec thing, then does that mean high CPU PLL /FSB volts is okay for 45nm cpus on P45 compared to P35/X38/X48 ?

Holy cow, that PLL is nuts. I can't imagine high PLL on P45 is any different than X38/48. Dead CPU FTL.
Well, this CPU is taking it without skipping a beat on stock air idling around 45C
Wonder how long it will last at those voltages.
I'll let you know
according to some ppl running 1.5v VTT will kill your CPU in a day lol
so does that mean 1.63 will take a few hours
actually it would be an interesting test since you don't seem to care if you kill the chip hehehehe
i have a feeling it won't be as bad as it's been made out to be
