Ok, so I have an MSI Twin Frozr GTX 770 and I want to use MSI Afterburner to overclock my card. Can I get some advice on voltage changing and what kind of overclock I shoud be able to get with stable temps. I'm idling at around 30C right now. I don't want to fry my card.
Also, should I overclock my ram even more. Its Corsair Dominator Platinum at 1866mhz at the moment.
Bump.
Hi - Monitoring your temps all the time set the volts to 1.0 or 1.1 and push the GPU up 100mhz and run a video benchmark tool, like VAlley (shows temps) then step it up 25mhz a time and slowly close in. Once stable bump your memory on the video card up with a step by step approach. Once all stable try to lower the volts and as you do you might/will have to adjust your clock speeds for gpu or mem. Never go above 95c in temp.
I would not worry about OCing you system memory thats already fast enough
Ok, I've been running unigine valley and I have a question about temps. My temps slowly rise the longer I run it, when should my temps be about 95c?
I push my cards until they throttle, or blow up. After that, you take the OC dawn, snress test, and find a good balance between temps, voltage, and frequency.
First of all, push the frequency up in increments of 25mHz on the GPU core, and keep the voltage at stock. Push that frequency up, stress test, try again, going until you crash or the card throttles. Then, bump up the voltage in, say, increments of .005, stress test, and keep pushing that frequency. Rinse, repeat, and watch your temps to make sure, under programs like Furmark or Unigine, that your temps don' pass 90 to 100 C. In real world applications, stressing your GPU at a realistic heavy, high-end load will be much lower, in the 70s to 80s at rather intense load.
Also, 1866mHz is plenty, but Dommy Plats are great chips, and should easily hit around 2133mHz CL9, at 1.55V or below. If you want more speed, your modules are definitely capable.
I'm a little confused, I unlocked voltage control, but I can't adjust the meter.
Ok, I got the new beta version and I can change voltage, but only by +1 at a time.
+1 volts?
+1 mV?
Precision is key ;)
what is a mV?
1/1000th of a Volt.
ok, the max I can go is +12 mV, what should I do?
+12mV increments?
no, just +12 mV more at the moment.
Well, push the frequency up, anyway. The stock voltages are pretty high, and more than enough for any decent OC.
Ok, but how long should I run unigine to see realistic temps, and should I set the fan up to 100% or something?
Leave the fan on auto. Run it all the way through, and check temps.
I prefer Catzilla to Unigine, though. It is thought out much better.
I'm gonna try it, unigine keeps giving me some fatal error that I can't read.
