I have the same CPU and evga P55 SLI motherboard. 3.8ghz is the max stable I could get for everyday without a big increase on voltage. Adding more voltage makes it run too hot for my tastes, and I have water set up. I would leave it alone. For GPU you got a decent oc on that already as well. What I do is run something like occt and keep bumping up in increments until it starts artifacting, then you can either stop and go back down one or switch to bumping up the voltage until the artifacting goes away again. Once you got core set, then do same for memory.
If you want the system to feel faster you should get an ssd. It would make a bigger difference in overall performance than bumping oc up a little more.
Yeah, I'm going to keep it at 3.8GHz for 24/7 use. Anything higher and I get system errors, blue screens, and the works.
I'm working with ATITool, which also has an artifact scanner, and I can't go above 890MHz on the core clock with stock voltage (1.013V). I don't know why, but Precision X isn't allowing me to up the voltage to 1.025V permanently. It will allow it for my current session, but as soon as I reboot or power off/on, it reverts to stock voltage. I asked around on OCN and was told I'd have to "flash my GPU's BIOS" and up the voltage through there to 1.025V. I'm not sure how much of an increase I'd be able to get with 0.012V more, but if it means another 50-60MHz on my core clock, I may consider it depending on how much more heat is put out.
The air vent in my room was fixed yesterday and actually blows the right temperature into my room, so my idle temps for my GPU have been 32-33°C and max load sits around 50°C at most (47°C after a 3DMark11 run benchmark).
Also, I'm slightly confused as to how I should be OCing my memory clock. As far as I know, I should be OCing my core clock primarily and once I can't go any further (stable) with that, I move on to the memory clock? Same process? Up 50MHz and then increase by 10MHz increments? The confusing part to me is why would my memory clock be able to be increased instead of the core clock with that same voltage?
Definitely looking into the SSD market. I've been eyeing them for a while, but prices have seemed pretty ridiculous. I'm also not too educated on how to transfer my entire OS and my regularly-played games onto it from my current HD.
