Overclocking G551JW with GT960M

[Piro]

I have unboxed my G551JW, and installed WIN8.1. Then I benchmarked it in old good 3DMark06 (1.2) with latest drivers from NVidia.
It scored about 22500.
Then I've started GPU-Z to check frequencies. After verification of temperatures I decided to tune it a bit.
I've used Asus tweaker. Unfair situation - it crashes the system.:mad:
Ok, I've moved to MSI Afterburner. It works, but overclocking of GPU is locked.:confused: NViddia driver 3.47.25 and newer support GTX960M but lock overclocking and voltage tweaking. BTW if I start GPU-Z together with Afterburner - system crashes reporting error in GPU kernel (nice new blue screen of win8, wow).
So I adapted older driver to be used with GTX960M, with success.
Now CPU (i7 4720hq) is set to 37,36,35,35 instead of 36,35,34,34 and GPU is set from 1097 ->1125 & memory from 2500 ->2900. I added some minimal tweaks on voltage of CPU and GPU (rather psychological effect).
I have tested it with 3DMark06 again. Now almost 26000 (always over 25900). There is no problem with temperature but I want to be sure so now I must replace thermal compound - I have ordered Arctic Silver 5 as internet says so.

I wonder if somebody of GTX860M owners or GTX960M owners (same product IMHO) has some ideas about proper settings?

To be honest I haven't focused on temp of GPU as much as I should. Probably under longer stress it will throttle itself.
Maybe because my G551 is new, it cools itself a bit better. I also increased cooling speed to be arising to 100% over 55C so it is louder but less vulnerable to temp. I use Notebook Fan Control app for control cooling (using Asus UX31A profile -it works).
The only thing I did was tweaking NVidia drivers to enable back overclocking and voltage control as it seems they have blocked overclocking at the moment of introduction of GTX960M.

PS: Today I've spent some time on memory speed setting and now my DMark: 4552 - (Fire Strike) http://www.3dmark.com/3dm/6998515 - fastest GT960M in 3DMark...

I am really surprised with your temperatures whilst being overclocked.
My reseller took back the PC and agreed that the temperatures were somewhat too high, I got faulty unit then, I suppose.

http://www.3dmark.com/3dm/6999665 my best score so far is 4243. Maybe my score is so much lower than yours due to only having 1 momory module (no dual channel) and slightly slower CPU. the 77MHz GPU speed difference alone can't give this much of a differnce.

[Piro]

Hmm, dual channel - yes this should have positive influence. But I do not believe such differences may be typical. Maybe thermal compound is not properly set at the surface of your GPU?
BTW I change my thermal compound soon (I wait for Arctic 5 delivery).
BTW2 I will see what will happen while Witcher III running. Maybe I will have pan for fries instead of my Asus. 😉

I saw this post in another thread, regarding changing the thermal paste & the warranty

If you do a teardown, I'm sure a write-up with pictures would be appreciated.

Oh yes, I know warranty rules and I understand clearly, that replacing thermal compound may be considered as "willish void".
But he who doesn't risk never gets to drink champagne. I will open it anyway and for sure I will publish photos.

Hey Piro, I just bought one of these laptops and am using Notebook FanControl, with the Asus UX31A profile as you said. How do I set it to adjust fan
speeds at a certain temp? Right now I can only see how to manually adjust the fan speed slider.

nice pics , need do that but im not sure :cool:

[dunedune]

how did u overclocked it ???? where is the method please someone reply

[ZIXEL]

I got 25865 without any tweak , just installed bios T06 , last nvidia drivers win8.1 no uefi
