Yeah, the new BIOS is fantastic.

Though performance of Phenom is still pretty pants - only due too clock speeds.

For the mean time im getting an X2 6400+ and sending the Phenom back, wait till the B3 9900.

Cheers guys.

Today I was playing with NB and L3Cache speeds

Some interesting findings...


First of my NB stable setting:

2736MHz(wish my cores would clock as well as NB )

I did several runs of 3DMark and Cinebench4D 9.5x64. In short:
3DMark06 Cat7.12 HD3870 CF 850/2442, Phenom cpu2464 NB2688 MEM 448 4-4-4 1T Score=13305
3dMark06 Cat7.12 HD3870 CF 850 2442 Phenom cpu2464 NB2688 MEM 448 4-4-4 1T.zip
3dMark06 Cat7.12 HD3870 CF 850/2442 Phenom cpu2464 NB2240 MEM 448 4-4-4 1T Score=12848
3dMark06 Cat7.12 HD3870 CF 850 2442 Phenom cpu2464 NB2240 MEM 448 4-4-4 1T.zip

For Cinebench4D 2.5GHz Phenom MultiCore scaling is:
NB2142 = 3.04x
NB2736 = 3.12x

Now is time for a break --> Crysis

Very nice mate. How'd you get NB that high?
Can I have a look at your voltage settings at those NB speeds and which voltages you can control in AOD please?

I am sure MSI board is different. If the next BIOS is not as good then I will probably try your board.

KTE 2.5-2.6GHz NB at default voltages (1.165V)! We can't adjust that setting from the BIOS yet....
My CPU simply likes high NB clocks! I set multi to anything I'd like in up to 2.8GHz speed and viola!
Looks like half of my Phenom silicon is really good and other half is not so brilliant....

Here is AOD SS showing max. I can set for NB voltages...

My 24/7 setting at the moment (except NB voltages which are default ). Read values from left column because this beta is + F3 BIOS is misreading real freq. under XP x64. It works fine for Vista x32 though.

PS. Max NB I was able to bench was 2840MHz

Max score I can grab is 13.8k 3DMark06.

That's with the Phenom @ 2.6Ghz - stable, btw and the two Radeons at 850/2500.

CPU is limiting them so badly.

Thanks for that Lightman.

You have SB but no CPU VCore in AOD? That's good in a way but bad in a way too.

I hate to be the bearer of bad news, but are you sure about this all?
CPU-Z has a known bug with flawed NB/CPU readings if you throw the NB too high in BIOS. We've been dealing with it for around 3 weeks now. What happens is, the system will downclock everything to keep your NB low near 2GHz. AOD as far as we know will report the most accurate values as the actual real frequencies. It happens because Phenom 9500/9600 cannot run more than 9x NB multi.
To verify all this, run EVEREST Ultmate and Crystal CPUID. They use various methods to detect the speeds. See if your EVEREST/CCPUID is reading the same as AOD (mem/ht/cpu), if they are, then what I'm saying is true and if not, then not so which is a first. I have a feeling your system is actually downclocked to keep NB near 2GHz and so the core/mem is actually underclocked and those AOD frequencies are correct. Because they only appear that way if Phenom takes a safety measure and actually underclocks despite the BIOS values you choose when they're too high (override).

I've attached an image of what the downclock looks like with a buggy CPU-Z and the correct AOD. Remember, NB actual high speeds will need more volts.
