Thanks. Well, from looking at my performance log graph its peak was 1320. Is that the correct way to gauge the boost clock speed?

So would you recommend putting gpu clock offset back to default, and then boosting the mem clock offset incrementally until it crashes, and then start boosting the gpu clock after it hits its maximum?

Exactly - there's a certain balance you need to get between core clock and mem clock. Personally, I would try to get your max mem clock offset without artifacts (blue snowflakes in Heaven). Once you find that, set your mem clock offset to that number along with setting your gpu clock to it's highest amount minus 5.

From my experience in 3DMark11 30-40 GPU Clock is equal to 600+ Mem Offset (7200 Mem Clock Total) so it's up to you to decide how much GPU Clock to drop... For me without the voltage tweak I had to drop from 1250->1230 (20) in order to get my 600 Mem Clock... With the voltage tweak my max gpu clock is 1282 and I only had to drop to 1277 for 600+ Mem Clock to be stable (a bit odd - I was thinking without any mem offset I would be 20 ahead of what was stable with mem clock).

By the way - grats on the 1320 Clock - that's a real nice clock. I got 1230 and I got it up to 1277 through voltage modding.

"This is the new Dynamic Clocking feature found on the Kepler-based GPUs; It will dynamically add more performance to the card if it's at a suitable temperature and suitable power percent."

I am running 55 degrees load and 125% Power Target and I only use 85% Power Draw at most. My Kepler Boost is 91 - I don't understand why I'm not drawing more.

This is the highest stable run I can get with no artifacts.

i7-3570k @ 4.5GHz
Asus DirectCU II (non-top) GTX 670 1269/3602 @ 1.175



In the top left corner of the picture you can see the PrecisionX value's.

EVGA 670 FTW

My stock boost clock is 1085 and my Kepler Boost is 65, which means that a GPU Clock Offset of 35 should result in a constant clock of 1185MHz. However, you'll notice that my maximum during the Unigine Heaven benchmark was only 1176. I've been having this problem since I first started overclocking it, and find it odd that it didn't decrease in intervals of 13. At any rate, it shouldn't be decreasing at all as I never reached the first temperature threshold (70C) nor anywhere close to the power target. Right now, after BF3 crashing, I'm at GPU Offset +33 and Mem Offset +500, but get 1170MHz instead of 1183MHz, and it sometimes goes to 1176MHz (all while under 69C). I am sad that my Kepler Boost is low, since that normally means my card is terrible at overclocking, so any help would be appreciated.

EVGA Precision x 3.0.3 is out. can't get a grab on it.

"qoute :What's New:

Added "Always on top" setting to the context menu of detached hardware monitor window. When this option is disabled, hardware monitoring window can be minimized to the taskbar when it is detached from the main window
Added hardware monitoring history logging support. Now EVGA Precision is able to save history in native RivaTuner Hardware Monitoring Log file format. The log files captured with EVGA Precision can be viewed in any text editor like Notepad or in graphics form in RivaTuner's HML file viewer (RivaTuner must be installed for viewing log files in graphics form)
Maximum framerate target increased to 120 FPS
Maximum length of GPU name for GPU selection buttons has been increased to 10 symbols
Added new "Force fan speed update on each period" option to the "Fan" tab. New option may improve compatibility of software automatic fan speed control mode with some bugged display drivers, overriding manually programmed fan speed under certain conditions
Bundled EVGA EVTune utility has been replaced with brand new EVGA VoltageTuner utility
Added bundled EVGA Bridge utility, allowing controlling EVGA Precision via Bluetooth from Android smartphones. The bridge utility is automatically started by EVGA Precision when "Enable external access to application via Bluetooth" is ticked in advanced settings
Fixed issue in skin engine causing boost clock marker legend to be rendered improperly under certain conditions
Added new "EVGA Classified" skin

Yes it is, sorry I went to sleep smile.gif . That is a great card you have there bud.

Alright, so after finding my memory clock's max first, then finding the gpu clock offset, I was able to get these results:




Still not as good as some of the clocks I've seen here, but better than last time.
