My temps are going to about 76C when playing battlefield or even running Heaven, I've attached screen shots to show my results on configs, but I'm not really sure what to turn down (memory or gpu core) to get the temps to stay 70C at full load. Any help would be appreciated. Thank you! Warning: Spoiler! (Click to show)

You should be able to get a higher score in 3DMark11 for your graphics score. I can run much higher core and mem clocks than I can in heaven:

I'm not worried about the score, it's the temprature that bothers me, they say it should be kept below 70C, but my temps go all the way up to 74-76C during full load. Also, I have turned VSync off in the nvidia settings, otherwise my Heaven benchmark scores drop down to like 935 or so which I assume is from throttling.

You are fine on your temps. 97c is the maximum per Nvidia. The goal of staying under 70c is to get the max boost clock. When you go over 70c but stay under 80c you only lose 13MHz. No biggie. I get the same temps on my #1 card in my 670 SLI setup.

Hello, Im new here and ive been following this guide to overclock my evga gtx 670 ftw.

I was able to pass furmark, benchmark heaven and 3dmark 11 @ +52/+635
I was able to play bf3 multiplayer without any problem or error.

here comes the problem, I run 3dmark 11 again and it crashed. try to run it again, and once again crashed, lost display and had to restart my pc.

OCnetfile.jpg

Kepler boost: 90.8
Max boost: 1175.8

Edit: lowered the power target to 125% and run 3dmark11 and heaven. both passed and no problem. I dont know if this makes any difference or it solved the problem.

will play some bf3 and run 3dmark11 again. Is it ok if I run 3dmark11, multiple times in short period of time?

2nd edit: bf3 crashed just now.

Hi, I've followed the long version of the OC guide, and it's hard to figure out what's causing me problems...

I have the Asus gtx 670 directcu ii (non-top) card. And I've been able to pass the heaven benchmark @ +145 CC offset and + 600 mem offset with voltage slider to max and power target to 122% (which is the max when I slide over to the right)...

So I was @ the mem offset part of the OC guide when I tried +700 mem offset which seemed unstable (no artifacts I could notice, but a super low score in heaven benchmark...) So, I decided to lower by 25mhz my 700 offset and so on... and I went all the down to +100 mem offset only, with a sucking score again...

I checked my graphs from the Precision-X monitor to check what could have been wrong... and apparantly, I fall into the category of people having trouble with the power %... It seems to drop by a quite a lot every now and then... which it didn't when everything was going great...

It feels like the more benchmarks (unigine heaven) I run in a row, the more problems I encounter... especially with power %. The way I can tell this, is from the graphs, but also from the FPS which is quite lower in the benchmark. So I guess I should lower the voltage limit... but what increments should I use ? or should I lower the power target instead?...

and if I do lower one of those 2, how is this going to affect my OC? And why is it that some of us have problems with the power %? What's causing the power % to variate so much all of a sudden, when it did not for quite a while?

(btw, I followed the guide very well, the temps are perfect... really confused here as to what's the problem...)

EDIT: After thinking about what could possibly be causing my sudden FPS drop after like 30~ heaven benchmarks, I got tired and restarted my computer, and put all the settings back like they were when I had passed with a +600 mem offset, and everything was like before all of a sudden... What the heck? is this RAM related?

EDIT 2: Seems like closing Unigine and re-opening fixed the memory leak I was having...

Just a FYI

I installed the newest Nvidia drivers tonight, 306.97. I then reran Heaven without changing anything else. With 309.97 installed I was running at 1189 mhz at +104 Precision X. With the last set of drivers I was running at 1202 at the same +104. I bumped it to +105 and I was then running at 1202 while running Heaven. I figured something might have changed so I tried to raise my overclock to 1215, which required +118, but sure enough it crashed just like with the prior drivers.

So my max overclock on the core hasn't changed. Yet I had to raise the offset by 1 to equal the same max clock I was getting with the old drivers.

I figured I would mention it just incase someone else has noticed there max clock has reduced by one level, -13mhz, with the newest drivers.

I was also averaging around 49.5 fps with the old drivers while running heaven and I am now averaging around 47.3. I am thinking about going back to the old drivers. The newest drivers don't seem to help my setup at all.

Hi there,

New member here... I registered for this thread specifically. Just wanted to send a big THANK YOU for the guide. It was easy to follow, and it yielded some fantastic results for me. Setting a more aggressive fan curve resulted in Heaven crashing for me, so I went with something a little noisier to maintain stability under full load. Ran Heaven several more times, and everything looks rock-solid. Played some games afterwards, and same thing... buttery-smooth with no artifacting. I feel so much more comfortable with this process. Thanks again.

Sorry about the image size... for reference, I was at 9092 3DMarks before a mild +105 GPU / +100 Memory OC.

If you have ANY sort of crash caused by an unstable OC, you'll need to restart your machine. This includes just a crash out of the Heaven app to the desktop. These cards/drivers never fully 'recover' and operate correctly once you've had an error from instability. May seem like a hassle, but with older cards, you'd pretty much always get full-blown system freezes when your OC was unstable ... which was even more of a pita, believe me.

On a somewhat-related sidenote, you should never alt-tab out of Heaven, it will get messed up and not run right after you do.

Everytime I try to OC my numbers go down. Even when I only increase my Power Target and Voltage.

What gives?
