~~The GTX 670 Overclocking Master-Guide~~ - Page 182

Will do mate.

Just weird thing I have noticed now. I can run the EVGA OC Scanner at 1175mhz GPU and 200 memory and not have any artifact or crashing. The moment I open up Heaven benchmark on same settings it crashes back to desktop with driver error.

In OC Scanner it shows Power % of around 110 and in Heaven it never goes above 105. *** is going on? Maybe this is driver related??

I'll try older ones to test.

Ok, my first time overclocking here. I'm using Heaven 4.0 at 1920x1080 with everything maxed and v sync off, last score was 966 (for some reason this time it also listed my iGPU in the results whereas every other run it did not). Anyway I'm using Precision and I can't seem to get stable past +150 core (1130MHz) but I can take memory up to +750-800 (1877-1902MHz) just fine. Is it normal to be able to get memory so high? And I keep seeing all these people taking core to like 1200+ easily...what's the deal? Should I try to lower the memory and raise the core? My temps aren't getting above 64C.

Also running an i7 3770K @ 4.6GHz, Windows 7 64-bit.

Well never mind, I wasn't adding in my Kepler boost which appears to be 130. I tinkered some more and got my max boost to 1280 with 1837 memory (+170 & +670). It's weird though, sometimes I get a pretty wide variance in Heaven with the exact same settings and it's not temperature throttling. The first time I got +170 & +670 to work, I ended up with a score of 970. I played around some more to try and get it higher but it wasn't working, so I went back to the +170 & +670 but then my score was only 938.

It should be noted that sometimes on Heaven, my temp will peak at 60-61 and other times it will peak at 64. When I got the 970 score it peaked at 64, and when I got the 938 it peaked at 60. What's up with that? Is that normal variance?

It'll have higher temps when the clocks are higher, so that's normal. Have you tried dropping the memory overclock a little and retrying Heaven? If you put the memory too high you can lose performance because of the error correction, so check to see if your memory overclock is actually adding performance. It also helps to use Enter to cycle through all the Heaven zones before you start the benchmark - helps prevent the crazy low mins you sometimes get when it starts a new zone the first time, and that can help your score also.

What do you mean about using Enter to cycle through all the Heaven zones?

When it first goes to the actual test and starts doing the fly through, you can press Enter and it will cycle through all the scenes. Then when you get back to the first scene again, press F9 to start the actual benchmark.

Ah. Why do you need to do that though?

It helps prevent the really low min FPS you sometimes get and provides a more consistent (and higher) score.

Ah you meant those low min FPS during the loading stage (start) of the Heaven loop?

I mean the low FPS you get when you run the benchmark. So instead of a min FPS of 22 FPS, you'd get a min of 26 FPS (for example). Here's what I'm talking about. Same settings, but one run was just load it and press F9, the other was load it, cycle through with enter, then hit F9. I just got tired of running them, and sometimes for no reason you'd get a min FPS that was like 7.5 or something. Doing the Enter thing seems to prevent that.
