3:2 divider problem?

I don't know how I managed to do this the first time, but I underclocked and tried to get to 2.7GHz again. But this time around, I found that whenever I set the memory divider to 3:2 and reboot, the PC won't boot. Just a black screen comes up, even though the system is running (fans and stuff). Even if I don't overclock, simply setting the ratio to 3:2 will keep the system from booting.

I can use A64 tweaker to set a 3:2 divider from windows (and it works according to CPUz) but I don't know how to save it at that.

No replies?

I see that I forgot my system info...

Abit AV8/Socket 939/K8T800Pro
AMD Athlon 64 3200+ @ 2.5GHz
2 x 512MB Corsair ValueSelect @ 208MHz.
160 Seagate Baraduda SATA150 HDD
eVGA GeForce 6600GT

If you need any other information, feel free to ask. I have the latest BIOS for the motherboard, so I'm not sure if thats going to be an issue...

Has no one heard of this problem before or something?

never had the problem sorry
