hi bro....

try to set your ram to lower mhz 1st.. i mean lower then default mhz..

then OC your CPU... if your CPU stable then just clock your ram.

this step is most OCer do it 1st....

yes hengmy said rite..

nvidia chipset really hard oc FSB to above 400mhz.. there is FSB barrier..

btw TS, did u know how calculate the divider at 1 place?

for eg: 1066 FSB / 4 = 266mhz x multiplier = Speed thus 266mhz x 3 = 800mhz ram... 3 = ratio.. as u see 1:1 ratio... (i take 2:3 ratio)
