Wont overclock at all? Am I missing something?

Hi guys,

I have a Phenom X3 8650, GB MA790x-DS4, and GeIL Ultra Low Latency 2GB DDR2 800mhz. Initially, I went to up DDR voltage to 2.1 and change timings to 4-4-4-12, like the ram is supposed to run, but If i change any of the timings, the system fails to start, and the MB boots back to original settings?!.

I went to go for a little overclock, so I manually set HT, FSB, PCI-E voltage etc. Found out, If any change of them at all, it goes back to original settings after no POST!. Surely this cant be right?!!. Am I missing something here? Also, the BIOS has no RAM Divider option, so I cant set the ratio for the RAM to run at right MHZ?.

Any light shed on this would be well appreciated Cheers.

Look under the VGA core clock control, there should be a setting called Set Memory clock. I think thats the DDR2 Clockspeed and not the VGA memory clockspeed - confusing I know but that might also help sort your non overclock issues.

Just a little something mind, phenom's don't overclock brilliantly, don't expect anything major

Overclocked MHz, are free MHz

There is a DDR speed thing, but its just the preset speeds of DDR2 i.e 667/800/1066 etc, theres no way to change the divider. Also, I only wanted to go to about 2.5-6 Ghz, but right now, it wont even do 2301mhz...
