First ever mobile GPU volt mod?! (105M)

Post #1 by TX-OC » Thu Oct 29, 2015 4:30 am

The GPU that iv'e been experimenting with is an Nvidia 105M with 256mb of GDDR3 VRAM, housed inside samsung Q320 laptop with T4300 2.10ghz cpu OC'ed to 2.8ghz, and 4gb 667MHZ DDR2 RAM (soon to be flashed to 800MHZ)

The stock voltage of this gpu is 1.2v, which allowed me to push the core clock to 880mhz (stock is 640mhz). Now after the volt mod, the core is now getting 1.46v

I haven't done much testing yet, as its 3:30am right now and I'm about to go sleep, but it appears that the GPU is now capable of pushing an amazing 1.1GHZ!!!
It seems to me that shader clock is limiting me from higher clock speeds.

Shoutout to nickolp1974 for thermal paste and ObscureParadox for the CPU ;) I appreciate the support, every little bit helps - as a student I dont have much money to play with
