770 throttling at 73C?

[Keudn]

My 770 is running at 1.27V and stays around 72-74C but it is still throttling. I run Valley and AB says the core clock is at 1333 but after a bit it starts dropping randomly and sometimes will go all the way down to stock. It usually doesn't throttle until 80C, so why is it doing it at 73C?

Check if the max temp setting got changed.

[Keudn]

Nope Power limit is set at 106 and temp limit is set at 95C

Kepler I believe starts to throttle after 70C try to keep it below that. But in reality you maybe lose 1-2 FPS.

95% sure it throttles at 80C, the 600 series did it at 70C I believe, the weird part about this is that the clock drops at the same spot in the benchmark and by the same amount every time I run it....

I found that if I left my thermal limit at 79 it would over heat and shutdown, start up gpu boost and set temp target to 69 ot better yet 62 (Celsius) I did that with mine and have had no problems since then. by setting the temp target it will crank up the fan speed rather than throttle.

Well do some tests. Crank the fan speed to 100% to try and keep it below 70 if it still throttles only thing i can think of is something else holding the card back. By that i mean it not needing to be at that clock speed during that part of the benchmark.

My fan speed is at 100%, and I'm running my 2500k at 4.8GHz and Valley is running off a RamDisk, I really can't give it any better of a shot at pulling off these speeds

Is GPU load at 99% during that part it downclocks? Also have you tried another benchmark like Heaven? 

[mrmonmon2]

What is wrong with your cooler? 100% fan speed cant handle it?

Answer of the answers: Desktop->*RIGHTKLICK*->Nvidia Control Center-> Manage 3D settings->Global settings->search for "shadercache" and DISABLE it (off) and save.

Could it be a driver issue?

Uninstall and reinstall or use another version?

GPU load stays at 99% and voltage doesn't drop

That actually changed when it dropped the core clock, it now does it later into the benchmark and doesn't do it as drastically, but it still does drop it

Did the same thing a few months ago and have been through multiple clean driver installs

 

Edit : another thing I have noticed is that the more I raise my voltage (while keeping the same clocks) the more the core clock drops and the more frequently, even though my temperatures still don't go above 74C

If the temperature outside is cold shut down your furnace close the door and wait 15 minute for the room to cool, then run it again. since you want the gpu to stay about 60ish and then throttling shouldn't occur, anyway worth a test.

Its about 20F outside and I have had my window open for the past hour doing this, its cold enough to where I have to wear gloves, I can't get the ambient temp any colder

If this doesn´t work, I can´t help you anymore

 

Desktop->*RIGHTKLICK*->Nvidia Control Center-> Manage 3D settings->Global settings->search for "power management mode" set to "prefer maximum power"

 

hope I helped you this time, good luck

[mrmonmon2]

I just set my gpu to 1333, will test with 3d mark because was going to run it anyway, ill see if its just yours or if it is a common problem

Have it set on that as well as single display performance mode, thank you for the help though!

Okay, thank you

[mrmonmon2]

well I just upped it to 1384 and going to try it, worked fine at 1333 fan sped was at about 50, but snow is blowing through my window, can feel it on my hands. running at 1384 now

Is that the clock speed in AB or Valley? Valley says my clock is 1397 but AB says 1333

[mrmonmon2]

1371 clock speed is my highest without crashing so far, 8010 mem clock, I ran 3d mark firestrike and was hitting 58 Celsius under full load, I don't have valley or ab installed yet

Okay, do you have more than 1.25V running? My problems start once I reach around 1.26-1.27V and only get worse as I up them until at 1.3V it rarely runs at the clock speed I set it to, and that is without changing the clockspeed, just the voltage

well since it was less than 10 F when the sun was shining and it been down for 3 hours now, my room is below freezing, downloading valley right now and about to install. installing and hands freezing through my gloves.

Okay, just don't get frostbite helping me!

1212 mv 1410 core 8010 mem, cant go higher since 110% power limit. can see my breath, about to run valley.
