.Welcome.First time post, first time PC builder, and first time overclocker.
After finally managing to get Afterburner to overclock beyond 1050/1450 (wish I'd found this thread earlier), and finding out flickering isn't an overclocking issue, I'm now starting to experiment.
I have the MSI Power Edition, which had a stock voltage of 1.21mV, and ASIC of 71.9
Initially, I put the voltage down to 1.1mV for the limited oc of 1050/1450 that I'd been running and that seems to be fine.
I'm testing stability using Sleeping Dogs benchmark and Kombustor. I've kept the mem at 1450 all along as that was the max CCC overdrive allowed so seemed a safe value.
I'm getting 1150/1450 stable at 1.179mV, and 1170/1450 stable at 1.2mV. 1200 definitely not stable at 1.2mV and I think I'd need 1.25mV for that. Max temp is 59 degrees.
So, looks like I don't have a great overclocker. Any tips for improving the clock? For example, would there be any benefit in reducing mem speed?
Also, I have triple voltage control. Do I need to mess with those separately?
Thanks
GPU Voltage may be too low at 1150mv. Try 1225mv or reduce the GPU overclock.Tried 55BUKs settings and keep getting this error after about 5-10 seconds of running heaven @ tess-normal x4 AA / Antistropy @ 1920*1080
Is this because i have yet to OC the CPU or have i done something wrong? Im also using his custom fan profile
1GB cards should clock to similar levels as 2GB cards. As far as I know they contain exactly the same components except for 1GB of missing VRAM. If anything, the VRAM on 1GB cards may clock slightly higher (there is less chance of 1 module being poor when you have less modules).
Some GPU's are just better than others. Purer silicon tends to require less volts to obtain a given clock speed. The purest silicon tends to come from the centre of a wafer (a large disc from which many GPU's are printed). Lower quality silicon may come from the outer edges of the same wafer.
What volts are you running for 1050MHz? I had one very poor chip that could only just manage 1050MHz at 1.225v. Try upping your volts to 1.2v and see how far she goes. The memory should be good for atleast 1375MHz.
Does PES crash when run at stock speeds or just when overclocked? If it only crashed when overclocked you need to add more volts (1.225v) or turn the clocks down.
Witcher 2 usually hits 2 C higher;p But this is on stock fan profile to be fair. 
It seems you have a poor overclocker then. I had one exactly the same, but even at 1000MHz these cards are great.
Can you help me with overclocking my graphics card please
download sapphire trixx, install it, the rest should be pretty straightforward. Slowly raise "core clock" by 25mhz until you crash in games, then raise voltage by 50mv (50mv=0.05v). I said "until you crash in games" because you're supposed to test it for stability in games. Also raise memory clock to 1375mhz, thats the max for performance for this type of gpu from what I've seen on this forum and from personal experience. Also turn "power limit" or whatever its called to 20%. It's the only setting that has "20" as a max. Raise it to the max. Most cards generally overclock to 1050mhz core frequency and 1375mhz memory on stock voltage so you can start there if you want.
