Overclock

Hey can anyone post me towards a guide on how to overclock the single 750m configuration? I've never overclocked a gpu before so I'm not quite sure how to.

Thanks in advance =)

 

You first need a program like MSI Afterburner or Nvidia Inspector, they both do the same thing. Just google them to see how to use them. As far as actual adjusting units and parameters, i'm not to sure, im still trying to understand that my self.

 

In after burner just set the core up to +135. Mine is stable between 100 - 125.
Memory for me is stable at 300/400.

 

Tried MSI Afterburner with Metro Last Light and Tomb Raider. OC'd with 50 core clock/ 250 Memory Clock but no improvement. Any suggestions?

 

Do 120-135 on core and 300-350memory will give good boost in tomb raider with the new GeForce 320 drivers.. As for metro the drivers aren't that good Gpus only use 58-70% max

 

And for an gt650m sli ? What you suggest ?

 

Can you please post a few more details gonna give this a try tonight with my new Y500 and Single GT750, really hoping to push Heart of the Swarm to Ultra and 1080p settings. Any little bit extra will help.

Plus is it as simple as moving the slider on the Core up to 135+ and the slider on memory up to 300, any need to move the voltage around ?

Down the line I am hoping to get, Batman Origins (the sequel to Arkham City) on the Y500, and Far Cry 3 not all to Ultra settings but maybe with SLI GT750 close to it.

 

No need to move voltage. just set to 135/300. If its stable, you are good. You can use furmark to test stability and temps. Try to also test a few games. If it doesn't crash mid game, you are set. If it crashes just start dropping core speed until you are stable.

 

135/300 is what I have mine set at... Always stable

 

Drop the core speed, or the memory speed. Or just up the core voltage.

The GT750M is capable of running at least 1100MHz on core, 1200MHz easily with very little overvolt. And at least 2700MHz on the VRAM. In fact the memory can do +400MHz easily, but I had to lower it just to get higher core clock speed. A higher core clock speed gives more performance, as I have seen in Unigine Heaven 4.0. And for overclocking on a flashed BIOS, I always prefer using Nvid Inspector, even though I have been using EVGA Precision for years.

Anyone with the SLI 750M should be able to come close to my score in Unigine. Link in sig. :thumbsup:

 

I tried afterburner a little before I made this post, and set it at the maximum it would let me. There was however no performance boost going by 3dmark.
