Good Windforce GTX 670 Overclock?

post #1 of 2
Thread Starter 
Here is what I got in Heaven. Bear in mind I am benchmarking at 1600x1024 at the moment as I do not have a proper 1920x1080 monitor as of yet, so that is why my Heaven scores are quite high, IMO. The highest stable overclock I can seem to get in Heaven is 1228MHz, anything higher and it crashes, even with Memory clock tweaks. Temperatures NEVER go above 60 though, so I'm wondering why going higher seems to crash, seeing as I set up a efficiency>noise fan curve.

A few degrees (like 60C vs 70C) doesn't affect the top overclock ... even water cooling (getting the card down to like 30-40C) doesn't really increase one's ability to OC much, if at all. So you shouldn't expect super-high OC's just because your card is running at 60C wink.gif

Barring increasing voltages or lowering temps like with dry ice, basically your cards OC'ing ability just ... is what it is. 1228MHz isn't bad for a 670. A bit on the low side, but certainly within the range of 'average'.

BTW, is this your actual, observed max boost clock (i.e. boost clock + kepler boost, as seen in the Precision Graphs while running the bench), or just what you're seeing in GPU-Z (just the boost clock)? Because +140 core offset on a Gigabyte 670 (that's what you have, right?) is almost certainly running at >1228MHz.
