ASUS AMD Beta BIOS Releases

[NEOAethyr]

Are you Prime stable with that setting? NB3000Mhz with 250 bus? Seems strange here (my max is 2500Mhz @250Mhz bus). With which CPU\NB voltage?

Fsb:		250Mhz

Cpu:	4x	1000Mhz		?
	8x	2000Mhz		?
	12x	3000Mhz		?
	14x	3500Mhz		-0.028125v
Turbo:	16x	4000Mhz		?

Vdda:				2.50000v

Cpu-nb:	12x	3000Mhz		+0.106250v (or +0.109375v)
Ht:	12x	3000Mhz		1.2000v

Mem:	8x	2000Mhz		1.6625v, 0.505x, 0.505x

Pci-e:		150Mhz		1.11300v
Nb:				1.1125v

Pci:	1/3	50Mhz
Isa:	1/2	25Mhz
Dma:	1/2	12.5Mhz

SB:		1.11300v
Vddr:		1.20575v
Nb-1.8v:	1.90200v

At the moment, with the new bios that was just posted, I had to up my cpu-nb voltage because I got a hardlock.
I up'ed it to: +0.112500v, it hardlocked at the 109x setting I have listed above.

All of the above was verified on the 1304 bios.
8hrs of y cruncher
12hrs of prime95, custom fft's of 4096k.
S&m's mem test, normal length.

And a few hours of ghostbusters.
Oh and an hour of zombie killing in black ops.
I've got alot of games to check still.

The cpu and cpu-nb voltages are setup in offset mode, hence the - and +'s.
The cpu voltages for each multi I didn't fill in yet, only the main one which gets the main voltage applied to it, the turbo gets an extra 0.1v on top of that.

Aida64 says this, not sure if it's 100% correct:

CPU Voltage 1246875 V
CPU/NB Voltage 1237500 V

If it is correct, it means when I hit turbo mode, 4ghz, my voltage needed is 1.346875v.

My sub timings I left completely alone.

Well 1.29 is not so low as CPU\NB voltage.

BTW I have another question for you:
real difference between these kits?
1) CMX4GX3M2B1600C9 rated @1.5V
2) CMX4GX3M2A1600C8 rated @1.58V
3) CMX4GX3M2A1600C7 rated @1.65V

I haven't found anything anywhere.

I can't say for sure, but just looking at the specs you posted, my guess is that there is 0 difference.
It's just the C7 set is binned.
The other 2 are the scrape.
Just my guess though.
