Found this in the Nvidia forums...directed to ManuelG. Dude has nailed it:

Straight up question. Need a direct answer.

When using manual fan of 68% or higher with the 314.09 or 314.14 drivers, on all GTX 600 products And titan products, causes massive downclocking / throttling that did not occur with prior drivers.

314.07 did not exhibit this behaviour. The new drivers are adding the fan speed to the total TDP of the card somehow, and this is complete nonsense - I have MSI lightning GTX 680s yet I cannot use 70% manual fan or higher because these drivers DOWNCLOCK MY CARDS. I use MSI afterburner and EVGA precision to monitor my GPU boost clockspeeds 24/7. At 90% or higher load, and 70% fan, my cards will max boost to 1050mhz.. My normal boost speed is well past 1300. If I revert my driver to 314.07, manual fan has NO EFFECT on boost speeds.

This is not an isolated incident. Many people at overclock.net are discussing this issue. THIS SHOULD NOT HAPPEN. PLEASE GIVE US A DIRECT ANSWER AS TO WHY THIS IS HAPPENING. MANUAL FAN 68% OR HIGHER SHOULD NOT CAUSE OUR CARDS TO DOWNCLOCK AND THROTTLE.

THIS IS A BIG ISSUE ESPECIALLY WITH TITAN CARDS.

I look forward to your DIRECT answer.

Pretty sure that was Xoleras's comment posted on the Geforce.com forums...

Yes, you are right, sorry.

I also found this quote very interesting:

"Now That was taken at STOCK FAN SPEED. I did the EXACT SAME TEST with FULL FAN SPEED and the card crashed right away. So, that pretty much tells me that the wattage of the fan is affecting the performance of the card - not necessarily how cool it is."

So what do you conclude after your mod? Why does your card still throttle even with more voltage?


the mod I've done edit: I should give poparamiro credit for figuring out the pin to mod from.



After the vmod I can really only conclude that the 265W power limit I've seen mentioned is a hard limit. When increasing the clocks & the voltage, something either hardware or software is throttling clocks & voltage to keep it in that 265W envelope. Unmodded I ran valley at 1228 core with the occasional drop to 1215, memory at 1800 (scored 3404). With more voltage, I have to drop the memory clock more to stop the throttle & end up with a slightly lower score (high 3300s). I can raise the core clock higher than I could before, so when running the mem at 1800 with the core at max 1254 it hits that clock a few times, spends most of it's time at 1228-1215 with the occasional drop to 1176, best score was 3417.
Leaving the memory clock at 0 I tested at 1254 & it didn't throttle, but scores were lower so I want the memory clocks...

I needs to find a way to bypass the power limit...
I'm getting ready to insulate the card & freeze it, hopefully colder yet will let it run faster/unthrottled when it needs a bit less juice than air or water can do.

And you're running the 120% powerlimit bios?
Hope you get the hardmod done it might give us more insight.

No bios flash yet, as it is now it never goes over 82 on the power target.

Good work FTW and hope you get the volts and power working in tandem.

Braver than me by along way. Hats off to ya Sir smile.gif

Unless my card normally throttles at way below 265W the 114% BIOS definitely helped me gain a lot of extra MHz and also lots of points in 3dm11. Can't remember the difference right now but it was very significant.
