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,

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.
This POS of a Mobo cannot do that in 99% of samples including later A3 Northbridge infact I have not seen 1 proven to be 100% stable at 500FSB with a Quad.
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.

Saturn, 533 FSB is a big ask, but hey, why not try.
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.
You should not need touch Skews for a Dual Core infact even GTL's can be left on Auto for 500FSB (not sure on higher) but you can tune lower votlages with proper GTL's.
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.

Well hurry it up already LOL
Every time I see one of these posts it give me hope !
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.
I can not come on Ket's page, how me to download Modbioses for M2F?

I can get 500FSB right now but it will not Stress for any length of time.
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.
use at your own risk

Thanks, but it has not helped me... mother does not wish 533Мhz to hold... I haven't already force and patience.
Maybe is the processor unsuccessful or memory?
