Trouble with GTX 670MX - Page 3

post #21 of 26
If it's not the drivers then it's afterburner flipping out. tongue.gif The 670MX isn't widely enough used to warrant proper support in Afterburner. I'd rather use Precision with that GPU. Also, push the memory clock as high as possible. That'll give you the best performance.

I O.C'd the video card +135, and the Memory to +900..If you look at the pic it shows the GPU @ 324Mhz. It does not seem like it is truly performing at that level..It seems like it is above..and afterburner is telling me it is at 732Mhz MAX..Very nice..Looks like 3D Mark 11 is just not showing it right. Next step..What can I use to O.C. my CPU?

I have the same problem with this graphic card.. I have MSI GT70 0NC laptop. I'am using MSI Afterburner with GPU-Z. Here is is screen from GPU-Z.. You can see that i sucessfully overclocked my graphic card to 750 core and 1200 memory. So I start any game (Crysis 2, Planetside 2) and i can play for i 5 minutes or so and sensors from second tab of GPU-Z show me clock 744 and 1198 and everything is ok. But after this time period of playing, clocks falls to 324 core and 400 memory. Only solution i found is to restart my pc, but you know thats not ideal to restart pc every 5 minutes.. :-) Do you have any idea what's wrong? And temperature not exceeds 60°C.

I have not had any more issues. The issue was the wrong clock speed was showing in 3dmark. it still shows the wrong speed, but everything else points to my correct O.C. I have not had your issue.

Ok, so I have to run few tests to try what could be wrong, because when i don't overlock everything is fine (clock 614 core and 700 memory stable). It could be software for overlocking (afterburner), too high clocks, bios, or windows 8..

I set only half clocks (688/953) from maximum possible and it won't fall to 324/400 anymore. Probably there is some limit which graphic card can stands. I just don't understand why it's limited by five minutes and then just cut its clocks on half of default amount and what software is responsible for this.
