so ... it is propably 1333 strap :( - or mobo set 4/5 div instead 2/3 ... don't know

Andre, have you tried this bios with Kentsfield? Multipliers up to 12 are available, but when I set it to 11 or 12, it ends up going back to 10.
Unfortunately, FSB is not as good with Kentsfield as some of the earlier bios versions.
Has anyone asked an Asus engineer about NB straps? Maybe they are using just one strap to cover all frequencies. If they were using several straps, why wouldn't they just make it available as bios option like on the Bad Axe? By the way, a 1333 strap would kick in much earlier than 400MHz. I think there is more to this than meets the eye. Also, I think some people are confusing the NB strap and the memory strap. They are not the same thing.
Boot @ 400*9

Boot @ 425*9

Boot @ 432*9

Boot @ 425*9 and Downclock to 400 with clockgen.

And if i boot to 400*9 and clock to fsb 425mhz, --> Reboot ^^
i smell a rat
i was wondering why my times were slower with 7* multi on E6300 on P5B Deluxe compared to 8* multi and slower RAM on E6400 on DS3.........well i'm yet to fully tweak the RAM and OS but from initial 32M runs it looks a bit :banana::banana::banana::banana: hmmmmmm
I have same problem. Bios 0507.
8x450Mhz is slower than 9x400 with same timing.
Everything set manualy in bios.
Is it fixed in 0609?
check my result .... with Bios 0609Quote:

Anybody tried the 0605 bios and checked if it really has the multi that is lower then 1:1, or tested the 0607 bios?

I would like to know aswell, Flashed the bios to 609 10mins ago but still havent done any testing.Quote:

there is no such thing as RAM divider below 1:1 on 965 and will never happen so don't even bother trying to find a bios for itQuote:

here is a partial answer..no mention of bios but FSB....Quote:

ASUS always cannot promise any overclock FSB higer. They just promise default CPU speed stable. So I only ask ASUS engineer to get me beta BIOS for overclock. Maybe Official BIOS is not good oc to use.
Kentsfield is no problems.

I decided to give 0609 a try today, but I ran into problems with random system freezes, so I reverted back to 0507.
My BIOS flashing history: 0302 -> 0405 -> 0507 -> 0502 -> 0609 -> 0507
>_>
Andre that is one impressive OC on that motherboard :toast:
just bumped into this thread, subscribed for when i get my p5b on monday
Seems that as FSB increases, so does the Strap, and as speculated this might might kick up to a 1600 Mhz strap, so i'm assuming the 1333 is going to kick in quite early.
High FSB at the price of a high strap and diminished performance.
Performance is somewhat diminished. But if you're running 500+ FSB @ 1:1, the RAM speed helps make up for that. Also, it's fun to run at 525+ FSB every now and then. And the P5B Dlx is the best board for doing that.:)
I think that with the 1333 strap the 5/4 divider (FSB/RAM) should be available, we'll see.Quote:

Perhaps that will explain why 8x440 is so much slower then 9x400.
Damn :( I ordered this board yesterday and I got exactly the OCZ2G8002GK-6400 kit.. So i won't be able to boot with them? That's the only DDR2 sticks i got :(Quote:
