Overclocking G551JW with GT960M

Piro
Level 7
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?

If you are looking for further improvements try to get someone to unlock the 135mhz limits in both mem and core like I did. Then you make your tests directly in oc software rather than hardware.

Guys. Dont push it to Hard on vBios. Put clocks around 1300-1350 on vBios and then use the 135mhz limit to explore. And I seriously advise.. . Do not go crazy with memory clocks like more than 2635Mhz... Otherwise you'll get bsod at Windows login and a very bad time in getting laptop to work again...

well so i cannot go up more than 2650 in Memory clock , i wanna go up to 2800-2900 maybe i need to change some voltages values like piro

Not voltage values, you need to unlock vbios

Hello there once again! It's been sometime since I've came here to check for updates. Well I've read your last PM's sent. Regarding the Mem clocks #Zixel It needs to be unlocked since they have a 150mhz~ limit to Oc, I've managed to get mine at 3200Mhz stable even being Elpida but my vBios is unlocked in both core and mem. For that you need more help than I can give. As I've already said I had the luck as Piro of getting a great modder unlocking my vBios, and unfortunately it's only compatible with this machine.
Now regarding #EtaCarianaeSC question, First of all, to start modding your vBios you need to make a backup of your current Bios with Afuwin64, last version prefered. Then mmtool to extract the vBios module out of the Bios, mod it and later replace the original one with the modded and save it. Finally flash it again with afuwin64. As I've already told, this voids warranty, can and will brick your laptop if any value goes higher than your Gpu can handle, Like mem clocks above 2635Mhz~ and core above 1350Mhz~. I Would suggest oc the core in an interval between 1250-1300Mhz. Since you'll later have a 135Mhz headroom to explore. This chip struggles above 1400Mhz and not mentioning the fact that it heats up like hell.
Guys be free to ask anything you want.

Kind regards from Portugal

Thank you guys so much!
I successedededed, and it wouldn't be possible without you.

Downgraded to the infamous beta bios - Check.
Overclocked the **** out of the 960m - Check.
Happy as **** - Check.
Repaste the notebook - Awaiting.
Find the ninja cutting onions - Awaiting.
1.3 ghz base, allowed slider to play with the 135mhz, ram +50 nothing too pushing.

THANK YOU!

P.S Does anyone else notice that the battery is being drained while OCed? :D. Not only that but if you remove it you get into the realm of 30ish % less performance.

I'm happy to see that you succeeded, have fun and play safe 😉
About the battery issue it's kinda normal, when you exceed the watt's it can draw from ac it drains from batt 🙂

Uhm, just wondering, how to undervolt the card from the bios? I see these voltage charts but can't seem to find the way they work.
Halp?

P.S Any idea why I am making 5032ish graphics score in 3d mark firestrike? (Reading there is incorrect, gpu is clocked at 1,45ghz real - as displayed
from real time gpu-z readings) http://www.3dmark.com/fs/9317683

While people with even less get 5200+. I sport a 4750hq, but that should not be causing any (if at all) difference? Overclocking the ram gives no results
whatsoever. A bad chip? A bad driver? A bad luck? Win 10 issue? 😄 No idea... Anyway I am still happy - N1 score for 4750hq system with 960m is MINE and MINE ONLY 😄

Thanks for the help and insights!

A fast answer would involve gpu and cpu temps. They can and will affect performance, also check if the difference is in physx score.
To undervolt at the voltage table, you only need to change the three first sliders from P16 state. Too low and brick, to high and another paperweight 🙂 Anyway the max you should be able to go is 1200mv since it's "limited by chip" I guess? or atleast I think so. I would advise something between 1143.8mv to 1193.8mv being the last the stock one.
Also the Gpu will adapt the vcore according to the clock you're using.

Have fun 🙂
