Hey guys. I took the plunge got a phenom II 920. The processor is great. I been playing crysis warhead @ 3.45 Ghz with and OCed 4870. it runs nice and smooth. but I need more Mhz, here is what I have.

Mobo: k9a2 platinum bios ver 1.6
CPU: Phenom II 920
RAM: 4x2GB for a total of 8GB in ram running at 840mhz 5-5-5-15 2.1volts
Drives: 3x sata 300GB hds and 1x sata Blue-ray player and 1x IDE DVD burner
PSU: Antec 1000w PSU
GPU: 4870 @ 830/970mhz


CPU and GPU are water cooled. CPU @ 3.45Ghz with 1.45 volts running at 33c idle and 39c full load. so it stays cool.

I have tried every combination of NB multiplier HT/NB/CPU/RAM voltage. I have dropped my NB multi to 4x and my FSB/RAM ratio to a 1:1 so it not the ram speed.

I set my CPU down 3Ghz and tried different FSB speed and I think I found the problem. I can’t get anything over 250mhz stable, not even 256mhz. I know from the k9a2 reviews that read this mobo can 280 to 300mhz on the FSB. am I doing something wrong? is there a setting I am missing? please help I’m sure i can get at least 3.7from this Phenom.

thanks guys
