View Full Version : OC'ing on my Asus G750-JW

Hey guys, I've been messing with some OC's and I seem to have a nice stable one for my GPU, which is 0997/0881/5500 and the GPU has stayed very cool with no issues.

Mainly I was wondering about OC'ing the CPU. I have one profile where changed Dynamic CPU Voltage Offset and Processor Cache Voltage Offset both to -70mv, changed processor cache ratio to 36, and changed my core multipliers to 36/35/34/34.

Now, this looks all cool on paper and increases my cpu to 3.6ghz turbo, but when I ran XTU's stress test for 5 minutes, my temperature made it up to 93 degrees celsius. I know that's lower than it's max, but it's close! I also ran skyrim for about 30min with a ****LOAD of Alduins spawned to lag me out, and it got up to 86 degrees under CONSTANT stress, so that seems better.

I also fiddled with a setting that is all default, but just undervolted to -70mv to reduce temperature, ran the XTU stress test for 5 minutes again, and it scored a max temperature of 87 degrees celsius.

I know a lot of people say OC'ing CPU's is very risky, and it could mess my CPU up, and that worries me because this laptop is my baby.

TL:DR, do you guys think I should just undervolt my CPU, or apply the higher speeds to it as well?

I have exactly your "profile" but in stress test it does not show higher than 3.19Ghz, and also with that V offset my CPU is 81-2 degrees on full load of bf4.

I don't know, but on XTU i've see some scores like 700 and something and i cannot get higher than 463-465?

I wonder....

IMO the best way to overclock the processor is to lower the voltage slightly. This will reduce temperatures and allow the turbo mode to stay on for longer. If you overclock then it'll just get hot, and then get throttled. It's a laptop after all, with limited cooling.

The other option would be to buy an external cooler, this should help reduce CPU temperatures and allow longer turbo mode.

Do you mind if I ask why you want to overclock your CPU? Most games are GPU limited, and overclocking the CPU doesn't offer a lot of benefit. Plus Haswell chips use turbo mode anyhow so they overclock automatically based on the load.
