And pull ins ? are they working?

i think 1307, still the best, 1802 is better than others, multi switched twice on me when i overclocked at high rates, i also think a little better band with, seems to boot faster.
Have experienced this issue, and found out after alot of testing that the CPU just is on the border of what it can take. My Q9550 was seemingly stable at 3.83ghz at 1,375v even 10runs of Linpack64 with 8gb ram, next reboot and it would not even be stable in ventrilo or general low power usage.
Backing it down to 3.7ghz fixed it permanently, and adding volt to the CPU@3.83ghz did not fix it, neither did adding NB/FSB volts to the m/b. My M2F seems to show the same instability on all quads at or around 450fsb, so I have given up on high FSB for 24/7 usage..
If adding volt to the CPU still produces instability, you could be seeing the end of the line for this chip, and if it's the FSB that causes the problems there is still possible tweaking left, but it might be a loong road ahead. I would suggest that you back off 100mhz or so, since trying to get it stable above the FSB/Mhz wall you are hitting might not be worth the hassle... Mine seemed better on 1:1 setting, but not not quite perfect there either....
I got hold of a very good QX9650@Q9550 price, and are now easily doing 4.0ghz 24/7 with 1.320v load with silent aircooling, I might go for more speed later if I can get hold of a "Ultra Kaze" at 1000-3000rpm, since this chip can reach 4.5-4.6ghz on air (allthough hotter then hell @ these clocks).
4.2ghz is the 24/7 target, as it needs around 1.40v for linpack stability, but for now 4.0ghz at very nice temps and silence, will do me just fine...
Much better George, good work. Made a big difference to my board too.
Thanks Cryptik..:cool:
I forgot to mention that i use a BTX case...!
Yeah quiet better like that m8...+1 for the WasherMod \o/
But don't care about that honnestly : what's up wit this MF bios men ?? Are we arrived at the end of the tunnel or what Cryptic ?
Gat my 12gb of DDR2 tomorow, so if it works for the bw : I'm buyin' :D
BIOS 1802
Lock'd multi ---FIXED
tREF --- 4174 :down:
Pull Ins --- still not working
Bandwidth --- unchanged altho my copy speed is up about 300mb/s
Seems Asus is making very very slow progress, new bios is stable and is supposed to offer us quad owners alittle more stability, so for those with troubles trying to get a chip stable try this bios.
Pull-Ins still do not work, tREF is unlikely to change for ram compatibility, seems to boot faster altho I did not time it, I have 1307 on bios 1 and 1802 on bios 2 so maybe later I will measure boot time. Going to try and lower volts now will edit and update this post if I can run lower on any setting.

I should be getting this mobo tomorrow,whats the best bios for my Q9300?Im running 4x1gb corsair 800mhz DDR2 (maybe this effects the bios choice?)
I have read that the latest ones aint too shabby but cant find the one you guys preferred.
Very nice George! Seems that washers did the job. :)
Seems like my board should also benefit from them but there's no way i'm unistalling it... :p:
Thanks for sharing your findings m8! :)
I believe that the major bugs like vtt/vnb and pcie are still there...?
Hi all, just got my M2F a week ago and it's running fine till now, i wanted a A3 revision but couldn't resist, so now i'm a happy camper with A2, temps are correct and the Leds remind me of carnavals. once again Thanks CryptiK and all members in here for this great thread. :)
Thanks for info. I bumped volts and it is stable again at 3.97ghz. Degradation or lucky 10 linpacks and 1h Prime Blend on lower voltage day before?
Anyway can't get it stable at 4ghz so far. Will test today 1802 bios maybe it will change something.
Also what voltage is considered safe for 24/7 q9550 in stress on Air? I read something about 1.365 which I am currently on :D
