my gpu core clock goes up and down all the time (gtx 660) - Page 2

post #11 of 24
I don't think anyone else has that issue. I have a second monitor so I have real-time info from Afterburner, and I sure don't have to run two programs to get max boost clock - and I've never heard of that from anyone else. If I run Heaven, or Furmark, or any game, I get full the 1275 MHz the entire time. Running multiple programs does not change what my boost clock goes to.

Can you post some screenshots? I'd like to see what you are talking about and maybe we can help you solve your problem.

I agree with Forceman..."but in a way, you both are correct on some things". Kepler Cards are not hard to understand or Overclock, they just have more things you need to learn about them to get proper overclock settings... It is a new architecture, so it's suppose to come with new stuffs, that's the point of it being a "NEW" architecture right? tongue.gif

Compared to fermi, which just includes setting a 3D voltage, and working your way from there to see what max overclock you can get on your core clock and memory, we can all agree that kepler is much more "stressful" and fermi is much more "straight forward" due to the "boost clock" which Kepler inhabits.

With kepler, you first have to run 3D applications at max TDP to see your max boost clock, then go from there to get your additional offset (+30,+50mhz..etc) then go on to overclock your memory. And just as soon as you increase your voltage (which can only be done with bios modding) unlike fermi, your former overclock could become unstable, because the card itself will increase it's own boost clock to something much higher....

@ 1.175mv, i used to boost up to 1267mhz (+80Mhz coreclock)
But @ 1.212mv, i now set the card to (+40mhz coreclock) and get a max boost clock of 1319Mhz.

I think what KGB7 is trying to say is that, with Kepler, the user has less control over it. Which makes it a pain in the a$$ sometimes wink.gif

EVGA 660TI SC 2GB.
Driver 306.97 WHQL


Here are some examples with stock BIOS. 1162Mhz

With Moded BIOS using KGB.exe the max boost is 1280Mhz But the issue is, is that none of the softwares will hit that 1280Mhz, except fro GPU-Z render test.

A) First image shows Render test thats built in to GPU-Z. Thats the only single test that will max out the Boost and will keep it there constantly all day long. But it doesnt put enough load on the card to stress it properly.

B) Second image is a shot of furmark at max settings. Its not showing furmark because i used PrtScn to capture the screen shot so you see it black. But its running on the main monitor. GPU-Z is on the second monitor. As you can see the the cards average speed, it wont hit max boost speed of 1162Mhz

C) Third image is for Heaven, it also came out black is it did with Furmark. Heaven settings are maxed out. But it wont Max out the card at the constant 1162Mhz. It rarely hits max 1162Mhz and only for a second.



Its the same exact issues with moded BIOS, even if i set power level to 200%. No single benchmark software or BF3 will hit 1280Mhz. It hovers in mid 1150Mhz.
I use MSI Afrerburner for fan control only, to keep the card under 60C so it doesnt lower the clocks at 70C.














Now the only time i was able to crash the PC at 1280Mhz, is when i was playing BF3 and watching a movie on the second monitor. This will Keep the boost at constant 1280Mhz and will crash the PC anywhere between 5-15min.
BF3 by it self, with moded BIOS, will keep the Core speed hovering around 1100Mhz.


Another issue that i have observed, is that the cards Core temp has to reach 50C to hit Max OC Boost speed. Other wise it will hover around 1130Mhz.

There is one person in BIOS modding/OC thread for 670 and 680 cards has same exact issue, but no one posted a solution. Im sure there is more people in same thread with same problem, but i didnt read all 300 pages.

Wait, you modded the BIOS? Maybe that's why it is a nightmare for you. Your experiences don't really relate to the general Kepler population.

Edit: Or are those screen shots from the stock BIOS? I don't know why your card is doing that - have you tried using Afterburner to monitor it? Here's my card in Heaven, you can see it keeps the full 1275 the whole time (except where it briefly thermal throttles at the very end):

I use both, GPU-Z and Afterburner. They both tell the same story.

Screen shots are for stock bios. But its the same exact issues with moded bios. I think i have tried my best to explain that in my post.


p.s.

What software did you use to capture you screen shots so you dont get black screen of Heaven?
Perhaps 680 and 660 cards act and work differently. I dont know, thats why i think its a nightmare with Kepler cards.


I made same post in 660TI thread, so lets see if i get an answer.
post #16 of 24
As far as I remember it was just a PrtScrn, but I was running Heaven in windowed mode, so maybe that makes a difference. You have the power limit turned up all the way? Furmark may still be being limited by the driver, which could explain why it doesn't max the core clock - does Kombuster do the same thing? I would expect Furmark and Heaven to push the power limit above 100%, so it seems like your card is maybe power throttled or something. You can see in my shot that the card is running at 120% power.

Edit: I get 120% in Kombustor also. Looks like maybe your card isn't taking the increased power limit setting.

if anyone thinks the 600 series cards are hard or pain in the ass to overclock your an idiot only issue i had was the MSI lighting bios was not unlocked so i flashed it

See how easy it is for you to say it?.. "only issue i had was the MSI lighting bios was not unlocked so i flashed it" tongue.gif That would take some people days to understand, not everyone is as tech savvy as some of us are. But everyone wants to play games biggrin.gif... It's kinda ignorant to say that, when some people don't know how to "Crack" a game... Lots of people don't even know how to use their task manager properly haha..

Found this thread. There is a work around that involves 3rd party software, so its a common issue.

http://www.evga.com/forums/tm.aspx?m=1770296

Kombuster does the same as well.
post #20 of 24
Still seems strange that your card is only going to 100% power though, instead of going higher when you change the power limit. If you try out the stuff you posted, post back with how it worked. Have you tried just using K-Boost to test it (without all the batch file stuff)?
