Overclocking Gtx 765M (G750 JW)

Neptun
Level 7
Hello folks,

I have bought the cheapest version of the G750 series(cuz thats all bestbuy had and i was on a rush 😞 )... well i have been trying to overclock my G750jw but i can't change the corevoltage, powerlimit or fan speed, i don't know why. I use msi afterburner and evga precision, by the way do you guys think overclocking the cpu (4700 HQ) will improve performance in games like battlefield 3 and skyrim?

thx for reading and hope you guys can help me 😛

Neptun, here is what I used to OC the GTX765 and 4700HQ in my G750JW

Asus GPU Tweak

23219

Intel Extreme Tuning Utility

23220

The Power4Gear Performance power plan in Power Options, or the utility itself to set Performance mode

Thx alot mate, i was overclocking my graphics card with evga precision and avg temperature was 61C , i managed to get + 15 fps in skyrim with everything maxed out wich i find good, do you think overclocking my cpu will increase frames in games too? also i'll try ur programs and the settings you using... again thx alot for your help 😉

edit--

Just tried the settings you used to overclock your card, they aren't stable for me, are they for you? or thats just a random img? if it is nvm, mb lol

Neptun, yes the numbers in the images are my stable settings. I used those settings to get these bench results:

I started with the MSI Afterburner, but MSI Afterburner maxxed out much lower than the Asus GPU Tweak allows.

BTW, ambient temperature, the surface the laptop is sitting on, and other heat related factors affect the performance - I have the G750JW set up so the vents have clear draw space for fresh cool air and vent the hot air out and away from the fresh air intake. If you have the laptop in a corner or against a wall the heat can bounce back. The worst is if you have the laptop set on a bed / cloth that blocks the intake/outflow.

There are also chip variations - some chips have more headroom for OC - and the heatsink seating / paste job on the heatsink has an effect too.

At 6288 I get clear video and no driver crashes. At 6400 I get both artifacts and driver crashes, I haven't tried in between, it is good enough. I think there is more headroom on the GPU frequency, but the Asus GPU tweak tool won't tune higher than 997.

Hey hmscott. Are you sure you're stable with that high memory overclock? Have you tried doing several Cinebench GPU (not CPU) OpenGL tests? Mine was usually stable with 3Dmark and regular use and even BF3 until I would do Cinebench, which would then throttle my GPU down to 450 Mhz and give me a terrible Cinebench GPU score of like 22 fps, requiring a restart to reset. My highest is 68.36 fps. Whats your FPS score ?

roryh86, stable at 6288 GPU: 65.38fps CPU: 7.32, multiple runs

with the same specs overclocked i get no where 65 fps. i get like 60 fps tops thats if im llucky on opengl cpu im always at 6 something points. 😕

Some GPU's/Memory clock higher than others, and even at the same frequency one may out perform another.

Also, before the frequency at which the driver crashes, the values approaching that frequency can have no effect, or even a negative effect on performance.

I usually tune for just before the crash, then step back to see the value of the top setting - eventually settling on a frequency that might be well below the crash point.

The GPU clock freq should be set to the max, but the memory clock is variable based on the program running. Some work with OC at 5500mhz, some only to 5150mhz, and I normally run at 5000mhz if I don't need the boost.

You can also get some improvement by adjusting the Nvidia Control Panel Global 3d settings, and adjust specific program 3d tuning as each benefit from different settings differently.

If you are really stable at 6288, I would be surprised, and happy if it was my GPU 🙂

You might want to start a bit lower, say 5500mhz, get a few benchmark baselines, and then scale up 100mhz at a time until you get no reliable benefit.

A 3-5% difference in run times at the same settings can be normal depending on the test and how much you have cleaned up services and tasks running on your system before running the test.

First of all thank you for your quick response. very helpful response right there. i tried slowly overclocking as much as i can but i guess you really lucked out because as soon as i get to 6100 mhz it becomes unstable like my games crash in the middle of playing but no driver crashes. and when i get to 6288 like yours..ohh screen flickers colors change driver crashes it just wont work. so right now i am at 5994 and its really stable no crashes or anything and gpu clock at 0997 voltage 0881 i am using the asus gpu tweak utility. i have the same specs i7-4700 HQ win 8 64 bit 8 gb ram. gtx 765m 2 gb. someone told me to change virtual memory to 7000 that it might help but i don't really think so. what is your advice on this?

Ah, there we go, I was sharing values from current G750JX is overclocking, when you are looking at the values I shared from my G750JW in earlier postings, much different. 🙂

JX - 5500mhz memory max
JW - 6288mhz memory max

It is luck of the draw on how well a CPU/GPU OC's. Something to consider is that once the heat-sink compound sets, it takes 2 weeks to a month of 100% CPU/GPU 50%-100% of the day, sometimes longer, then you get a little more OC, in many cases. I have been running FAH and BOINC (CPU + CUDA) and I am getting more stable at the edges on this JX in 3dmark.

Besides, a couple of hundred mhz in memory speed won't translate into much of a performance difference - one you can feel - it's just one that shows up in benchmarks - something to not get unhappy about. The important thing, I have found, is to get the games / work going, enjoy the awesomeness of your laptop, and leave the benchmarks in the review view 🙂

Besides, in 3-4 years, your new laptop will benchmark 2x+ as fast 🙂

Here is my laptop from a few years ago, Crossfire 2x 4870, kicked ass in it's day, now less than 1/2 the speed of the G750JX:
