Phenom II 955 shows as 1.6 ghz in Windows 7

[MillerSM]

I just installed windows 7 rc on my new build. The bios detect the 955 as 3.2 ghz, but when I go under the systems tab it shows it as 1.6 ghz. What's going on? Do I need an update? Or do I actually need to flash my bios? Thanks.

Entire build is
Phenom II 955
GA-MA790XT-ud4p
4 gb g.skill
sapphire 4890
1 tb hd

could it be caused by amd's cool'n'quiet? or it could just be win7rc not detecting things right.

Yeah. I'm not sure. I disabled CnQ and it didn't change. I turned on performance mode and nothing, but setting it to x16 in bios causes it to be detected at 3.2. However I noticed my default CPU voltage was only .97v. I thought I had read it's supposed to be 1.4? Anybody know for sure?

Hmm CPU-Z reports it as 800 mhz and only 4x multiplier unlocked. Some people say flashing fixes this others say a windows 7 update does. Anyone know for sure?

Ive been reading up on Gigabyte fixes for my board on their German forum - which is excellent http://62.109.81.232/cgi-bin/s...b.cgi?&a=forum&forum=2 even with beta-bios section not avail. elsewhere 🙂 Well the 1600mhz and too low voltage is among known bugs, and not about C&Q though that is what one might think. You should flash to F4 bios or whatever is latest. Goes for more than your model, mine needs a beta - now I just need the cpu... In case you can understand the lingo here is an example of the answer people get with same problem:

Hallo,
beim 955 gab es anfangs Probleme mit der richtigen Taktung. Da lief die CPU zu langsam (nur auf 1600MHz) und mit zu wenig Spannung (1V). Vermutlich ist der Bug im Ur-BIOS des 790XT drin und es gibt deswegen das F4G. Updaten geht aber mit der CPU.
Gruß Oberst.

Yeah. Flashing to 4g fixed all my problems. I saw it in other forums as well. Thanks for the help though. I appreciate it.
