cl9 im not 100% sure on the rest of the timings cause ram just confuses me so idont touch it

before i undervolted i was at 1.4 stock and that didnt work either

Watch your temps, try it up to 1.5v.

Max on air is 1.55v, but with your temps don't try to prime it. Just try to get SC2 to launch.

People run over 1.5v everyday, they just have better cooling.

SC2 is dual threaded so it won't stress your chip anywhere near the heat level of Prime 95.


Here is my 1090T @ 4.5GHz.

Notice the voltage, then the temps.



If you want 4Ghz, you're gonna need to pump more voltage into the chip. The chip is getting hot, because its hot the current is being restricted, the current needs more pressure (voltage) to deliver the power the cpu needs for those clocks.

You could settle for getting 3.8GHz stable, then get your NB up a bit higher for a better experience. The extra 200MHz isn't going to make or break your overclock.

Starcraft 2 is pretty much a stability test for your cpu in of itself. I was running at 3.7GHZ not to long ago and everything seemed stable. I could run prime 95 fine, 3dMark 11 fine, every game fine.... except starcraft 2.

I would periodically get crashes in starcraft 2. Everything else seemed fine though so I thought it was more a starcraft 2 problem then a cpu overclock problem. But then I downloaded 3dMark Vantage. And on the cpu test my computer actually crashed about half the time at 3.7 GHZ. I realized that my cpu overclock was actually the culprit.

I have since down clocked to 3.5 GHZ and not only do I no longer crash in 3dMark Vantage cpu test, I no longer crash in Starcraft 2, or anything.

Some times finding instability is not as simple as prime 95, and most games. In my case the only programs I had which were able to cause my overclock to be unstable was 3dMark Vantage (not 3dMark 11 which is kind of strange) and Starcraft 2.

yeah now im just at 3.6 @ 1.325 volts and now its all stable so im glad

Your 4.2 was not stable. High overclocks on your chip were 4.1GHzish with 1.55V+. If you want anything stable over 4Ghz you need:
  • Good cooling
  • Well over 1.5V on vcore
  • Make sure load temps stay below 55


These overclocks were done with 1.6V about 1.575 with vdroop but I had custom water cooling at 50 degrees under load.

yeah I agree about SC2.

I had my fair share of crashes with 4 GHZ O/C while playing SC2. A 4v4 with full maxed out graphics makes me feel the bottleneck of my 955 at stock clock speed and stock NB.

I don't even want to remember loading SC2 on my old 1.6 dual core laptop with Intel graphics. I'm surprised I even got a slideslow.
