P5WDH, Rev 1.02G, BIOS is this new BETA 2301, CPU E6600.

CPU 1.6
RAM 2.4
NB 1.7
FSB and ICH all at MAx on bord BIOS volts

RAM 1:1 4-4-4-8-12

Read dealy is 7 via memset in Windows, I botted at stock clock 266.

I used Clock Gen and uped FSB to 270, clicked apply and it freezes.

Has been doing this everytime. This is the first time i have tried it at stock clock.

In clock gen i am setting the right PPL, ICS 954123 and am clicking read clocks, nothing more happens and i then click exit to close that part. Open PLL control and it's reading everything as it should be!

I have no idea whats doing it. Clockgen version is 1.0.5.3 latest off there site!

Have tried SET FSB only gave me a max of 307fsb which worked!

I also can via BIOS go all the way to 407mhz before it wont boot anymore.

Any ideas as the 6600 does do 3.8!
