Nvidia GTX 560M - Overclocking (128-bit version)

I saw a blog post here: http://www.bestgaminglaptop.net/general/gtx-560m-overclocking-128-bit-version/

Does anyone have any experience with this? How safe is it to overlock the gpu? How much of an FPS boost did you get?

I OCed the 560M (3GB DDR5) in my G74 to 850, 1700 and 1600 MHz (Core, shader, memory). That pushed my WEI graphics scores to 7.3 from 7.2, but I haven't benched it with anything else yet nor looked at max temps (however, idle temps did not change: it still idles near 36-38C, one to two deg. cooler than the CPU).

I have had plenty of success on my g74 (the best buy version) overclocking to 945,1890,1525. It sees a jump of 8 fps in Skyrim for me running on almost max settings and loads of high resolution graphics mods. I haven't found a setting that is super stable in Battlefield 3 yet. Then again I also haven't looked very hard (finals take time). The temps they recorded are surprising. I run Skyrim for hours and it doesn't even hit 70 degrees Celcius.

the most stable OC I could use that lasted the most without crashes is:
874/1748/1371

Any1 managed to get it higher and stable for long time?

Btw. When you overclock it to its maximum stable numbers, you will only gain about 3-4 fps and nothing more on a game like crysis 2.... So actually you don't need to overclock it

Currently running mine at 870/1740/1550. Stable for everything I've tried. G53sx-XT1 driver 285.67.

Edit: People with the G74, post your results in the thread for the 192 bit cards. There seems to be a difference in overclock potential between the two models, from what I have been seeing.

I've been playing crysis 2 for like 2 hours in a row with 1920*1080 and "gamer" details if I remember right, and I can tell you the difference between stock clocks and max stable oc clocks are HUGE. I'm talking about 10+ fps here, and I'm not joking, so it is definetly worth the effort. Been playing with 930/(1860)/1700 lately. I don't understand these low readings of memory clocks I see. Push some more juice to the mem ppl! But of course this is the 3gb 192-bit model and g74sx so I know it's a different thing, but I remember that the 128-bit has a plenty of go when talking about OC too.

Here's for this thread too, 3dmark11 run without errors or artifacts, notice the clocks.

for those who replied and said it is stable, please mention which model you have 🙂

Also, if you could add what drivers you are currently running as well.

I have the g74sx bbk7 model (128 bit) running 925/1850/1600 stable. verde 285.62, I only oc when playing crysis 1 or 2 all the other games I play don't need it, but in those two games it makes a big differance, this model has a LG phillips display 1600x900 but that res helps the frame rates I believe,over clocking also bumped my wei score from 7.1 to 7.3.

if you are not playing games very often, but just want to have fast graphics for all else that you do on your system, would oc the gpu be worth it still. and does it do any damage to the system? i would guess if it still runs fairly cool, then it should be fine.
