950m overclock

[Tech_Gamer21]

Hello all, I am new to these forums so please correct me if I am doing anything wrong here.

 

I have overclocked my gpu which is the 950m with 4gb of Hynix ddr3 memory, I've overclocked it using Nvidia Inspector(screenshot below)

I already have the temps under control with the aid of a cooling fan. I get about 56c idle and when gaming it reaches up around 70c to 80c (as I've seen)

 

I already know the risk of overclocking laptops as most laptops don't have that good of a cooling solution compared to desktops. What I want to know is if any of you guys have any experience with overclocking this card or a rough extimate on how I can increase it while still being somewhat stable.

 

Thank you for your time LTT community

 

(By the way the wrong voltage is on the screenshot, it's meant to be +31.3 mW, not +18.8 mV) (I am also on Windows)

so it crashes without adding voltage? Usually with the 135MHz cap set by Nvidia the most beneficial thing to overclock is the memory, especially since it's DDR3

[Tech_Gamer21]

It doesn't crash without adding voltage, I just set the voltage higher so I could increase the mem clock a little higher, it may have been wrong of me to do that though. When I increase the mem clock +300 I start crashing. When I tried yesterday Chrome started artifacting and my laptop started to crash. I quickly set it back to where it was stable. Maybe adding more voltage should give it a little more headroom? Or maybe it's the ddr3 memory reaching it's limits

[Tech_Gamer21]

Tested my theory out before and I was correct on the memory reaching it's limits, after setting the voltage to +43.8 mV and the mem clock +300 MHz my laptop immediately started bugging out, things started hanging and eventually crashed, then the screen blacked out and went back, I checked out gpu-z and my overclock was reset. I have moved the mem clock a little higher, +280 MHz

[Jurrunio]

voltage offset set here doesnt affect the memory at all, only the core voltage, so just drop that back down. In fact maybe undervolting helps with thermals which then allows memory to OC further? Not sure if that effect is big enough to be noticeable.

[Tech_Gamer21]

Alright, thanks for the info, I'll give it a try and I'll keep you posted with the results

[Tech_Gamer21]

Drivers broke, gotta reinstall

The drivers broke due to the event before, unstable overclock

Your not going to get any performance benefits OCing that board.

I gained a little more fps when testing it on heaven, so a little difference

I had a laptop with a GTX 850M 4Gb DDR3 which is the same GPU as 950M. I was able to overclock core speed +135Mhz and memory +180Mhz which gave me nice 10-15% performance boost without temperature issues. However it was still too slow GPU for modern games. Some people used custom bios to overclock further than +135Mhz and some chips were able to reach +350Mhz overclocks.

[Tech_Gamer21]

I was thinking of using a custom bios since there is one available for my system but I'm worried about this whole memory clock, since after the bad overclock yesterday my laptop was artifacting on me today, which was most likely due to the too high mem clock and the undervolt combo I had on it. I already the max mem clock which is +280 but the core clock could be raised up +200 or more, since with my oc now I get 77 c
