Overclocking the NVS 140m (safely!)

Hello

I have decided to use the most current drivers, which are 175.97 from Lenovo on my R61 widescreen running Vista 32.

I am trying to use RivaTuner to experiment with some overclock settings - does anyone have experience regarding how high one can push Core Clock, Shader Clock and Memory Clock?

Riva has a "Performance 3D setting that says Clock 400, Shader 800 and Memory 600 but is that safe?

Thanks in advance!

 

I'll let others chip in on those different settings, but in general OC isn't a sure thing for safety, ever. So even if you do it a little bit you could have issues because of it down the road. :S

 

if you truly want to be safe about it, you should take steps to keep it cool.
swap out thermal grease, undervolt, etc..

rivatuner cant go past that limit for "safety" reasons. however you can change that in the power user tab

I can do 650/975 no artifacts and it runs just fine. playing the devil may cry 4 demo (1024x600 - everything on high), the temp never goes past 55C.

I can go way higher (i think the sweet spot is 702/900) but I get artifacts

 

Thanks, Batman - when you say 650/975, is that Core/Memory speed? Would it make sense for me to adjust the shader speed too?

Thanks!

 

yeah 650 = core and 975 = mem.

I dont play with the shader as I use ATI Tool (.27b2 is the only version that seems to work for me) and I think it automatically adjusts it according to the core's speed
