Hey so i have the G751JL-DS71 and am overclocking the gfx card (gtx 965m) using Nvidia Inspector to overclock, afterburner to monitor temps, valley and firestrike basic for testing. My question is what are the safe levels for this setup? Anyone done it? Asus advertises 5% overclock but this is what ive been able to do so far:

Driver: 355.60
Core clock: +135mhz
Memory Clock: +300mhz

Witcher 3 (1.08):
From 35 average fps to 47 average fps
Valley:
From 23 lowest fps to 34 lowest (highest 74)
Firestrike:
4876 points to 5193
Max temps: 74*C CPU and 68*C GPU
Result: http://www.3dmark.com/fs/5852792

I did push the memory to +350mhz once and ran valley for 10 minutes. No artifacting yet. Looking for advice/suggestions/experiencees

I use +120 to core and +350 to memory on my 980M, I'm guessing there shouldn't be too many differences...
If it works for you and the drivers don't crash, at those temps - my only advice is keep it as it is. You can't up the core clocks any further without messing with vBIOS etc. anyways.

I did exactly the same. Didn't dare go over 300. It's probably safe, though. The cooling on this model is phenomenal! DId you try overclocking the CPU? I haven't, and I was looking for some guidelines. Cheers! That's Witcher 3 on Medium, right?

why not crank the core to 135mhz?
I havent messed around with the cpu yet. Just unparked the cores. Just downloaded intel xtu today but dont really see the benefit of tweaking the cpu just yet. Plus with 300 mhz we het nearly 90gb/s rates so thats like a 13% increase with almost no thermal difference. And the witcher 3 results i posted are with 1080p shafows on normal rest all on high plus postprocessing fully maxed (all). I used 370mhz and no artifacting yet. My firestrike was 5193 but the highest one is ~5600 with a G751JL

I definitely wouldn't go over 350!

Any specific reason? Or just personal qualms?

Because +300 is 12% OC. That's already pushing it. Each to his own, though! If you find that your PC is stable, go for it :)

What s/w are you using to OC your 980M? I tried ASUS Gpu tweak for windows 10 and it never saves the values :( ...Well it wont apply them....Is what i mean

Gpu tweak and msi afterburner noth dont work for me either. Values arent queried, saved or applied on startup. Use nvidia inspector. Clean easy andminimal

Actually, that's the first time I've seen anyone say MSI Afterburner hasn't worked for them.

But GPU Tweak is a lost cause, don't bother with it.
I run +120MHz to core for stability, sometimes the drivers crash at +135.
Stock memory is set to 5010MHz effective, I can go up to 5950MHz before I start seeing artifacting.
So almost +450MHz to memory is possible, I run +350 regardless.

MSI afterburner keeps polling the sensors for me but not much else. Im going to try attaining a 5700 firestrike score ove this weekend. The highest score is on a JL with 355.6 drivers. His clocks are:
1059 Core
1525 Memory bus

So i over clocked with evga precision X 16 GPU CLOCK OFFSET is +135 and MEM CLOCK OFFSET is +375.
GPU CLOCK now reads 1084MHZ GPU TEM goes up to 67 degrees celsius ran it for hrs no problem at all. I get anywhere from 40fps to 55 fps on
witcher 3. Runs like a beast!
