24/7 OC worth it? - Page 2

post #11 of 24
If you use MSI Afterburner to overclock the gpu you can create profiles and just run the oc'ed one when necessary. I did this with my GTX480 worked like a charm.
Other programs probably have profiles too, this just happened to be the one I used.

Ok so my gaming OC is 900Mhz, 1088mV Vcore, and fan speed (auto but goes at 85% for temperature above 60°C).
I'm currently running OCCT gpu test, and the temperature hit 84°C. Is that dangerous? should I lower my OC? is there a way to make the fan go even faster then 85%?

I overclock my 2 GTX 580's 24/7. Aside from when I am using it to play games, I also do Folding@Home, and OC'ing it DEFINITELY helps.

The problem with 24/7 OC'ing is that while I can get my cards to OC at 1GHz for short periods of time, for 24/7 OC'ing stability, I can really only run them at about 900MHz.

I comply with what you said

two different 680s with the same clock 1110mhz

before starting a heavy-duty game , I click the two profile to start the NV inspector , let the clock be 1176 boost to 1254 @ 6600
especially I control the fan curve manually , let the two type fan in each fixed speed

when I quit the game I'll cancel the profile to default and change the fan curve to auto mode

other conditions I use the two card in factory clock ( 1110 to 1176 @ 6008)

this is important because when the cards' clock is up the whole system's fan will up too

so choose the profile to do it ( for me another profile is Asus Fan Expert 2)

What about the 85°C in OCCT is that a safe temperature or should I be worried?

I noticed that my GPU automatically throttles down when Idle, OCCT indicated that the GPU is speeed is down to 405 Mhz and memory to 324, but As soon as I start the test it goes back up to 900Mhz and 2048Mhz.

85% is very high. It's not dangerously high, because the cards can handle up to 90C without any problems. But it does definitely make the card's lifespan shorter than a card that runs at significantly lower temperatures. also, for cards like geforce 670/680/690, any temperatures above 70C will throttle the card to lower boost speeds.

Alright, I've just check with no factory setting my card reach 82°C in OCCT. Anyway underload in every other software, (3dmark 13, heaven, metro 2033, hitman absolution) my card reaches maximum 75°C. SO I suppose I'll stick with that configuration.

Also as soon as I start using Furmark with an OC, my computer instantly shuts down and restart. Any ideas why?
Thanks

overheating most likely.

But Furmark don't even start. I see the screen one second then instant reboot.

So it doesn't open at all ? It doesn't reboot after starting the test?
