NVIDIA GT 650M Benchmarks

[kisetsu17]

Hi guys,

When playing game, I noticed that the Core clock of Gt650m on m14x R2 always throttles down and run at 270-400 Mhz after a few minutes instead of 745-800 Mhz although the temp is OK (~65) and I have enabled "prefer max power performance" on Nvidia control panel. So the FPS will be dropped
I tried new beta driver 304.48 and latest bios A03 but nothing changes. It looks like this is the power management issue.

I've seen this behavior on my laptop when I alt-tab away from the game.

Hey all,

I will try to update these benches at the weekend.

Can't do it during the week as I have now started a month long intensive HSE commercial scuba diving course. So I'm out most of the day and still busy in evenings!

Cool

INSANITY!!!
How did you reach that score?

With the help of svl7 I can increase my GPU core speed to 1070 MHz and yet this is the best I have scored on my MSI GE60:
NVIDIA GeForce GT 650M video card benchmark result - Intel Core i7-3610QM Processor,Micro-Star International Co., Ltd. MS-16GA score: P2947 3DMarks
and this is the best I have seen from a Alienware M14x R2 at the same core speed
NVIDIA GeForce GT 650M video card benchmark result - Intel Core i7-3610QM Processor,Alienware M14xR2 score: P2920 3DMarks

I have been out of the loop for the past 5 days, what is that svl7 mod?!?
Prema, i'm willing to test out 6165 bios mod if you want?

I asked svl7 if he could help me to increase the GPU base boost clock of my msi ge60 NVIDIA 650m since he had done just that for the alienware m14x R2 and he customized the bios. I 'm testing it right now, I'll let you know if he wants to make it official. All credits to svl7!

Here's a link to Premas bios mod for the clevo w110: http://forum.notebookreview.com/sage...c1-review.html

Ah thats the one for w110er, I meant the one for w150erq/np6165, unless the same mod works for both?

Happens to my Samsung NP550 as well - doesnt matter what drivers I use, after 20 minutes gaming temps at 87 or 88 c and the clocks drop every few minutes.

After 3-4 weeks of using a new Inspiron 17r SE with a 2GB DDR5 650M I have re-benchmarked it in 3DMark Vantage and 3DMark 11 and seen a significant drop in GPU performance.

The 3DMark 11 GPU score has dropped from 2091 to 1866 and Vantage from 8490 to 7665.

I've used GPU-Z and apart from optimus diabling it, the clock seems completely locked at 745.2 MHz with no boost to 830 MHz occurring. This would seem to explain the performance difference.

I have tried MSI Afterburner, NVidia System Tools and EVGA Precision, but any changes to the clock speed I seem to make using these tools do not actually change it according to any monitoring tools or benchmarking.

I have also tried the latest NVidia beta drivers, which do not seem to help.

Has anyone got any ideas either why the boost has stopped working, how to get it back or how to overclock successfully?

Have you checked your temps? and have you maybe changed your power profile to power saver by mistake? try putting it on high performance if it is not on it already

Thanks for the quick reply - GPU Temps are fine, idles around 45 and when doing the benchmarks was only getting to 60 or so.

The power profile is on high performance.

Did you by any chance update your BIOS? Your vBIOS might be embedded in the BIOS and that might be the reason why. Sounds like a vBIOS lock to me.
