Overclocking EVGA GTS 450

post #1 of 6
Thread Starter 
So until my Hyper 212 Evo gets here I decided to toy around with my 450. I know overclocking a 450 is about like overclocking a pinto car but it's what I have for the moment.

I just have a few questions but first the info. I currently have my core clock at 900mhz, shader clock at 1800mhz, memory clock at 1880 and my fan speed is set to auto. I had my core clock up to 925 and was testing it in Skyrim when it froze with looping sound after about 5 minutes in game. So I hard rebooted and dropped the core to 900.

Is there a point where I should be messing with the voltage and would that help or hurt?

Also, I'm assuming that 925 is about the max I can go because of the looping sound error I got? I didn't see my temps go above 42~62C on full load and I know that is perfectly normal, would upping the voltage change my temps drastically?

Thanks in advance.

Upping the voltage will up the temps, but as long as you keep it below 90C your fine.

Ok cool, thanks for the info. This is really my first time overclocking anything so I'm assuming that upping the voltage will also up my performance? Would I be ok to keep pushing the clocks up with more voltage as well?

Upping the voltage does not change the performance, but it can increase stability. Think of it like using a higher octane gasoline, until you actually put the pedal to the medal (Overclock it) its still going to idle around the same. Some people start with the OC they want and gradually bump the voltages until its stable. Others start with max voltage and see how hard they can push the card.

So long story short upping voltages will not increase performance, but it should allow for a higher overclock, which will increase performance.

Awesome, thanks for the help Matthew. I started with the OC and have gradually been upping the voltage. Going to see where it gets me.
