I have a Samsung 14" NP355V4C laptop with the following specs:
GPU: HD7660G + HD 7670M Dual Graphics
RAM: 6GB DDR3 1600MHz (4GBx2GB config)
GFX Driver: 8.944.2.1-120405a-137159C
HDD: 750GB 5400rpm
I have a couple questions regarding drivers for the dual graphics set up. Firstly i would like you know the newest driver availiable for this set up and also do dual graphic drivers differ from those of a single GPU? Do the catalyst drivers (ie. 13.4 or the 13.6 beta) apply to me or do i have to go to the samsung support site and only download thier drivers? i have tried downloading catalyst 13.4 and installing that but it didnt detect my graphics adapter.
Also regarding the Dual Graphic setup is there a way to disable the HD7660G and use only the HD7670M? I noticed the oftenly that the HD7660G is being used more than the HD7670M; which never goes past about 60% usage and highest temp i've seen it go is about 68 celcius.
I also have a question regarding the a10 CPU, im a bit concerned about the temperatures of the cpu while gaming. the cooling on this laptop isnt that good (fan seems a bit mediocre). but the temps i get on this laptop on idle is 45-50 celcius and on while gaming after about an hour it gets to about 90 celcius (sometimes even as high as 96). My guess is that since the HD7660G is on the same chip as the cpu it generates more heat, when the 7660G is being heavily used. Is undervolting a possible solution? i have a cooling pad but the 30CFM fan doesnt seem to do alot (it helps a bit). Another thing i noticed is that when i unistalled the catalyst install manager while attempting to update my videocard drivers and restarted to install (or rather attempted to) catalyst 13.4, the cpu even when idle went to about 85 to 90 celcius and eventually hit 108 which forced a shutdown from my laptop. i was looking at CoreTemp and noticed the VID after unistalling the catalyst install manager was at 0.7000v at 898.38MHz where normally it should be 0.1750v is there a reason for this?
Overall it is a pretty good gaming laptop (microstuttering from dual GPUs aside) considering the price i payed for it ($549.99 CAD) but the heat is really ruining the experience for me.
