GTX 670MX Overclocking [Updated-custom BIOS file] - Page 52

post #511 of 514
This thread is kinda dead but still, I want to share my results at 950MHz core/1250MHz memory, stock voltage, including games benchmark. I can overclock further with voltage tweaking but I don't know if the VRM can really handle that much. It can go up to 1150/1400 at 1.1v for 15% additional performance but the fan has to spin like hell to cool that monster. (but it's nice to reach a stock GTX 870M, damn almost 5k for graphics score on Firestrike http://www.3dmark.com/fs/2570230 )

Resident Evil 6

Gain : +59%

Sniper Elite V2

Gain : +68%

Tomb Raider (Ultra (which is not maximum settings in this game))

Gain : +67%

The Last Remnant

Gain : +67%

The Witcher 2

Gain : +64%

You can see huge gains even without modifying the voltage, it reaches the performance of a GTX 680M. In some games, minimum fps can even surpass the max fps of the stock card.
Just nice, up to 70% (or even 100%, yes, you can if you are not affraid of overvolting, example on Tomb Raider) gains for free, GTX 670MX is just a hidden monster. What else?

Darkomax, is there any chance you'd be willing to share your vBIOS with us?

 

 

My G75vx is currently running a modded vBIOS which basically just has the overclock limitations removed... no overvolt, but still just being able to bump it up to a solid +330 core / +305 mem on stock voltage has made a frickin WORLD of difference!! In fact, I just recently had to do a complete dis-assembly of my laptop in order to swap out my ailing stock DC jack and while I was at it I....

 

 - swapped my stock DC jack for an HP big-barrel type so that I could start using a pair of 230w HP adapters I had on hand. The voltage spec is identical to the original ASUS adapter and they have been working flawlessly thus far!

 

 - did a full CPU & GPU TIM re-paste with Arctic Silver 5 paste as well as a thorough cooling system cleaning... I suppose my factory TIM must have been fine because I didn't have any cooling issues beforehand nor did I really see a difference afterwards

 

 - I then did the "cold air intake mod". Came across this on the ROG forums... using the stock metal fan grills/filters as your template, you cut round holes into the 2x bottom plastic access panels directly below & in-line with the cooling fans and then you epoxy those grills/filters into those holes. This allows the fans to easily pull nice cool air directly at their intakes. Made a very noticeable difference in my max temps but I find it works best when the back of the laptop is slightly raised... doesn't take much, a pair of 1/8 inch or so rubber feet on top of the stock feet did it for me

 

 

... anyways, now I'm itching to overvolt this beast and see what it can really do :devilsmil

Hi guys I have g75vx too, with moded bios, but I have no idea of how properly OC it, not sure what values I have to enter in inspector.
Any suggestions?

I can't give my vbios because I have a MSI graphics card, it would brick your graphics card.
And actually, I just did the mod you're talking about on my laptop, and it worked very well for mine (-5°c). There are 2 downsides though : it will eat dust so you have to clean the fans very often (unless you use a dust filter, Demciflex ones is very effective) and the fans might sound louder because of that wide opening.
I even have a modded Notepal with a 12cm fan running between 5 and 12v just in front of the graphics card (upper mid part where is a large heatsink).
