GTX 860m overclocking

[Kenna]

Hi bros,I recently got a lenovo y50 laptop with a gtx 860m,I have overclocked a gpu before (gtx 780) and i decided to try it on my lappy, However when i oc it i can only add 135mhz on the core clock. Iam pretty sure i can push the gpu even further as my temps stay around the 50c. Is there anything i can do to add more mhz on the core.

Help will be appreciated 

 

Current 860m setting 1155mhz core (1020+135)

Memory is +700mhz

From what I understand you don't really want to overclock mobile GPUs because of the confined space they are in will drastically effect the cooling of your other components.

I don't think overclocking a laptop gpu is a good idea.

[Kenna]

The laptop has 2 separate cooling fans and heat pipes, for the gpu and cpu, so i dont think that is to much of an issue 

[dragoon20005]

even with OC

 

the GPU is still slower than a Desktop GPU

 

and they burn up faster

Even so not ALL of the heat is carried away by the fans and the heat pipes.

you will not want to overclock your mobile GPU or else you will be sorry.

Don't do it.

@Kenna: Please don't listen to the 'knowledgeable' naysayers who don't have a clue.

My w230ss is using a 860m overvolted to 1.20v, running @ 1340 MHz with 5700MHz on memory, temps stay under 80C under heavy furmark load or gaming. I have the top 3dmark firestrike extreme score for this system configuration, although many members on NBR with similar laptops managed to push their machines even farther, at lower temperatures.

Considering that the 860m is LITERALLY the exact chip at the same specs used by the GTX-750Ti, yet I'm pushing it higher than many desktop users get their cards to run, the "desktop GPU's are faster" argument is moot (also check the link for the 7970m crossfire mod in the R2 - 7970m being a slightly cut down version of the 7870 desktop card - the crossfire brings performance at the level of a GTX-titan GPU, inside a laptop).

I also have the 4700mq CPU overclocked to 3.6GHz, undervolted by 75mV, staying under 85C.

Absolutely stable.

In order to manage temperatures better, my bios is unlocked to allow for maximum fan speed on demand, and I am using a cooling pad under the laptop at home for when I run in this high-performance mode.

i am using a modified system bios made by Prema (you'll get to find out who he is and what he does if you get into this stuff - http://premamod.com/)

Afaik, prema is also working on an unlocked system bios for the y50, but you'd have to ask him about that.

 

This is within a machine with a single cooling fan and only two heatpipes overall, 13" form-factor, under 2kg.

 

Here's some benchmarks:

For enthusiast questions relating to laptops, i recommend visiting notebookreview.com and/or techinferno.net. As you can see, with the right choice of machine and tuning, you can have laptops running similar performance as desktop machines or beating them, even several generations behind.

There are, of course, risks involed. You manage that risk by informing yourself and knowing when it's safe to push the envelope, and when it's not. And you should do so with a community to help and guide you along.

I have the same question, did it work?

[Weyromon]

i have a lenovo y50-70 and i tried evga and msi overclock utility and i cant overclock the gpu, any idea why?, i raise the bar like +20 and click apply, and its resets to 0 , btw its a gtx 860m 2gb

[Lucas1727]

I have an Acer Aspire V Nitro with GTX 860m 2GB as well similar to Weyromon and im having the same problems as them with msi afterburner as well as programs live riva tuner statistics server on screen display not being able to read my core clock and just shows 540mhz even when its not, anyone have a fix or reason to these problems?
