PROBLEM on overclocking

i had a GTS250 and i couldn't adjust the voltanges on it. Not even if i went into the settings and enabled voltage control on MSI afterburner. but now that i have a GTX460 i AM able to change the voltages.

Im not sure on the support for the GT220 (pic dont work but im assuming by your sig thats what you have)

how about fan speed???

im afraid tht my GPU is way too hot .....
i use the MSI Kombuster to load....
it is 74 degree celcius (peak)under full load...coz the MSI afterburner writes tht its under full load....
is it too hot for my GPU???

my stock core clock is 625 mhz

shader clock: 1360 mhz

and memory clock is 790 mhz....


and now i overclocked it to the following....
core clock: 770mhz

shader clock: 1675 mhz

and memory clock :870 mhz....

is it too OVER for my GPU???

it's very safe untill 80C
your GPU can over handle 128C (very very HOT)
