Hello to everyone,
I can not achieve stability in Prime95 in any way... Increase of Vtt/NB voltage gives nothing... Subject matter about GTL read, but it does not help.

You do not even list your CPU !
If that is a Quad (even if 45nm) you have no chance of that FSB even to boot to windows.
If its a Dual (esp if 45nm) you could get it stable at that FSB easily with some tweaks.
I am sorry,
Intel Core 2 Duo E8400 [E0]
Asus Maximus II Formula [bios 2302, Intel P45 rev.A3]
Geil Ultra Plus 2x2Gb DDRII 1066Mhz 5-5-5-15
Microsoft Windows® 7 Ultimate x64
Ok a Dual 45nm CPU good !
A good sample of this Mobo could hit 600FSB (not all) but it depends on your Memory also.
Your also lucky you have a newer Rev A3 Northbridge.
This all is clear, but as to me stably to adjust FSB=533, Prime95 strews mistakes... Nothing helps.
Guys, can you share you 500x8, 500x9 bios setting for q9650 please :)
You have little to no change m8.Quote:

Someone somewhere may have got lucky and have 500FSB 100% stable though.
Most top out about 475FSB and any more takes lot of tweaking and extra voltage.
I got to 485-490FSB but it was not worth the extra time and voltages, it was stable 1 day and not the next, that's Asus for you.
Iam agree with you... My next board choice goes not for ASUSQuote:

If you fail, just set 444fsb (easy on low volts) and use the 9 multi for the CPU and use the 5:6 divider on the 333 strap to get your ram at 533.
This should be a super 24/7 overclock.
If you are still serious about 533, then I would suggest using uneven clock skews, perhaps increase cpu to 300ps and leave NB at 200ps. This might dial your fsb back into trim - it worked for me albeit on a quad.
Does not help... :down::(Quote:

I was only limited by my Memory not hitting 1200MHZ when I tried to get 600FSB on my old E8600.
I only really had to mess with GTL's and Skews with the Quad.

There is a new Bios out at the Asus Support page. Supports the new C2D series as I know so far.
:wave:
Hi
This my settings on the M2F, may be useful to someone.

it seems i made my chip working at 500x9 :) some pics soon

I am not on newest Bios as it supposedly is only to add a few newer Dual Core CPU's.
I gave up messing as above 475FSB too too much time and voltage/tweaks and was not stable from 1 day to the next or infact 1 boot to next reboot.
I tied mines down to needing the 50ps instead of 100ps increments for Skews on CPU and NB but Asus never did add this.
There was no point in me having 475FSB with low voltages and no major tweaks and then having to pump to far higher (still safe) voltages and tweak like mad for days to get 480-490FSB to find it was stable 1 boot and not the next boot.
nice oneQuote:

Pics or it didn't happen :DQuote:

I have seen it and heard it all and have yet to see a MFII pass Prime etc at 500FSB on a Quad.
I know there must be a few lucky ones with good sample Mobos out there though and it does not matter if A2 or A3 NB.
@Saturn,you can try the DL Linky at the bottom of the page.the first one dont work.Quote:
