Hi everyone, I have been slowly OC'ing my GTX 765m. I got it to 997, 881, 5500. It upped my preformance from 28-30 fps in High on Far Cry 3 to 29 - 30 fps on Ultra in Far Cry 3. My temps have maxxed out at 65 degrees C. Has anyone gone farther than this OC?

Thanks.

UPDATE - I pushed it to 997, 881, 6000. My preformance went up to 30-32 fps on Ultra In Far Cry 3. Temps maxxed at 67 degrees C under load.

UPDATE AGAIN 😄 - I got it to 997, 900, 6000. It is pretty stable. Good temps 5-10 fps improvement in games. If you raise the Memory Clock to anything above 6000, games start to get glitchy. I raised it to 6100, and Far Cry 3 started having weird texture issues. This is the max overclock i have been able to get. Temps max at 67 degrees C.

Best Preset for Far Cry 3 with this Overclock is Very High. It manages to average 30-31 fps.

😄

Can you explain a bit your numbers and what software you used. Is it Asus GPU Tweak? I use MSI afterburner and maxed out the core overclock +135 and the memory +1000. So under load, my core reaches 1032 Mhz and memory 3005 Mhz (as double rate), max temp 67, I haven't touched the voltage, but it's been stable.

What's your second number (900?) after 997? And I dunno why GPU tweak puts memory as 6000, it should be half that. Have you played with voltage?

Yea, I am using Asus GPU Tweak. I got my GPU Clock to 997. I played around with the voltage and brought it up to 900 with no issues. For some reason in GPU tweak i can bring the Memory clock up to 6000 MHz, but if i bring it anywhere above, my games start to have tearing issues.

EpicSniper, thanks for the reply. I stopped using Asus GPU Tweak cause it had some crashing issues, and its monitor feature doesn't have FPS monitoring, so I'm using MSI afterburner. Yes, I've noticed too than anything over 6000 (actually 3000 it should be) causes throttling on the GPU and core drops to 450 Mhz.

As for your 900 voltage setting, in fact that isn't doing anything. Because the GPU has a dynamic Voltage from 0.850 idle to 1.037 under load. If you want any benefit from voltage, you have to set it to anything above 1.037v, like 1.1v, which would then become the new voltage ceiling (0.850 to 1.1), it will stay dynamic. But I don't see any necessity to adjusting voltage as yet, maybe when we have an unlocked VGA bios to increase core clock higher.

roryh86, thanks for pointing that out. I set it to 1043mV in Asus GPU Tweak, and the monitor showed it did max out at 1043mV during a Furmark run.

I would like to limit the voltage to below 1037mV to see if it still runs, to reduce heat. How can we do that?

Increasing the voltage made my 6400 Cinebench 11.5 run fail much more spectacularly - nice artifacts and my first freeze requiring reboot - voltage is back to under 1037 🙂

Hehe yea, it froze with me as well with higher voltage. Well the Asus GPU tweak (the only app I know of that allows you to play with voltage on our Asus GPU) doesn't work Windows 8.1 which I have installed. Keeps crashing. So I'm not sure if there's a way besides a modified VGA BIOS to lower the idle voltage. Have you tried lowering the Asus GPU tweak voltage to like .8 or .825 and see if it undervolts (using GPUZ)? Btw, I've noticed, ironically, that with +960 Mhz on memory I get better FPS and scores than +1000. Although +1000 is stable.

I've been seeing your Futurmark results over the forum a few times, have you tried 3DMark 11 Performance (P) preset? Curious to know your score. My latest highest (Also currently G750JW online highest 🐵 is 4927. Here.

My new high actually. Here. 😛

roryh86, did a new run, first after updating to 320.49 and XTU bump, first run 4969

Very nice result hmscott! 🙂 I hit 4985 last night on second run that I didn't upload here yet although you can see it on the 3D mark comparison. I'm sure you should be able to get higher though since your memory is clocked higher. Is your GPU still at stock voltage? Can I ask you what your CPU overclock and voltage settings are? I noticed that lowering CPU voltage helps keeps high GPU overclock stable.

Edit: I also noticed you're getting Valid result verified driver on Futurmark. I'm still getting a Graphics driver is not approved :confused:
