7670m maximum MEMORY overclock.

Phazoner · Jul 2, 2014

Hi guys, i have a 7670m on my laptop, that usually got 1gB GDDR5 or 2gB DDR3, but Toshiba's genious made this 7670m with just 1gB DDR3, so there's a bottleneck with GPU's bandwidth. It's checked by pushing mem clock from 900Mhz to 1070Mhz and getting up to +50% fps on several games.

I don't know where i have to look to make maximum OC without destroying my PC. Just temperatures? Voltages?

Thank you!

Phazoner :

overclocking on laptops isnt recommended and overvolting isnt possible and shouldnt even been mentioned! laptop cooling or even dc adapters are barely sufficient in most laptops even on stock settings. ensure you are within safe temp zones,way below 90c at all times.what temps do you have at stock speed on both cpu and gpu?

Laptop's CPU is an i5-2450m. Turbo is disabled and i'm ever looking for dont overpass 80°C, but its usally on 70°C. GPU working hard is on 60°C, and overckocked from 600GPU/900mem to 780/1070 is only going to 65°C and CPU gets only +2°C.

I'm not afraid of temperatures, i want to know other reasons that can be dangerous to the system or can make it unstable.

Phazoner :

your cpu-gpu voltages are locked and cannot be changed. your temps are very good i must say. even so, laptop components dont have the tolerance desktop have. you should already be satisfied with the performance you have already achieved.!also, as said, dc adapters dont provide any headroom for additional power consumption since they are provided and intended for using with the specific stock specs of the laptop. i wouldnt try to further o/c anything.!
