Sempron 3000+ should run at 133MHz FSB says BIOS

[Dus]

Hi all,

The Sempron 3000+ in my AK79D-400 Max is run at 1600MHz (CPU Frequency detected = 133MHz). The cpu is an SDA3000DUT4D. The board should recognize it as 166MHz FSB capable.
At start up it does show 'Sempron 3000+' and sets the voltage at 1.6V which is good. So I guess Model 10 (Barton) support is only half implemented.

I noticed that for the AK79G-VN board there is a beta BIOS with Model 10 support (1.07 adds Sempron, 1.08b adds Model 10) so I asked AOpen about an update for my board but the engineer can't find the source code anymore. (It's what they said.)
Comparing those BIOSes tells me one thing: I know far too little about this stuff. For one thing both system bios and xgroup have changed.

So if anyone can tell me what needs to be edited (only a default setting 133 to 166 or is there more?) or changed in whatever way please do.

page 24 of 115, there you need to set the FSB. For sure if you let the bios detect, it will use the normal 133MHz.
