Sean said to set boost to clock to 1100. Done. That's a -24 offset for me. Ran Heaven, checked GPU-Z, found my max boost clock to be 1124. Subtracting my boost clock (1100) from my max boost clock (1124) gives me a whopping 24. Same as my offset. I have a very hard time believing my Kepler boost is a mighty 24MHz.

Does this method not work with 680s?
Your offset is -24 ? Run at stock find highest core clock with GPUZ.As an example, here's mine:
My boost clock:
26

My Maximum Core clock:
38

My Kepler Boost:
So i take my Maximum Core clock (1257) and subtract my Boost Clock (1152) and that will give me my Kepler Boost value of 105. If you want to be really precise, you would then want to round to the nearest multiple of 13, in this case it's 104MHz, to remove any rounding errors in the software. taken from the guide.

There's no reason to try to figure out your card's Kepler boost, it doesn't actually matter. You can distill the process into four steps - set maximum power target/limit, increase core clock and memory clock offsets using Afterburner/Precision, test, go to step 2 until it stops being stable. Start with something simple like +50 core and +200 memory and see how that goes. You can check your actual boost speed in Afterburner or Precision (or the monitoring page of GPU-Z - don't go by the front page) to see how you are doing compared to other cards. The value of your Kepler boost is irrelevant to the process.

Are you messing with voltages at all then?

No, the only way to actually increase it is to mod the BIOS.

Wonderful. One less thing I have to figure out. Thanks mate.

Back to testing the old way then. redface.gif

I know overclocking the memory is easy for the GTX 670 but my GPU clock is abysmal.
I have an ASUS GTX 670 DC2 (non top).
Default clocks:
GPU: 915
Memory: 1502
Boost: 980
Overclocks:
GPU: 1015 (+100)
Memory: 1752(+500)
Boost: 1080

I guess i am happy with the 10% gain in my Heaven benchmark
Default:

OC:


Ive been reading in many places that people have been able to get very close, if not over +200 via the ASUS GTX 670 DC2 for the GPU clock. Also in over all, resulting in a 1165 boost clock.
My card crashes as soon as it goes over +100 (even if i downclock the memory to just +300). Am i doing something wrong?
Or should i be happy?
Join the club buddy. My Asus 670 DC2 is horrid at overclocking. Going over +120 shows me crazy numbers in Precision X. My max stable is +78 on the GPU core and +300 on the memory.

There are a few samples 13mhz lower, but they are few and far between. We dont have the luxury of being able to read the BIOS source code, but it looks like that logic decided the power target was not exceeded enough to warrant downclocking/volting from the current 1241 / 1.137 levels.

Sorry if i came across as argumentative, I'm not meaning to.

No problem, I was trying to not be argumentative either. The strange thing is that my friend's card seems to clock down even on stock. I had him do a full run of Heaven 3.0 on everything stock and this is what the log looks like. gtx670STOCK.xlsx 24k .xlsx file

No matter what overclock we set it, the card down clocks a few times. For example he can get 1280 it goes down to 1254 or 1241, but if we try to get the overclock to be 1241 thinking that it won't down clock, it ends up dropping to something like 1215. It just seems like his card likes to down clock no mater what the offsets are set to. The more I try to figure out what is best for him, the more I get confused.

It looks from that log file that the card is just power limited (all the 1s in the power column). You can see where it downclocks and downvolts for power for significant periods, even going as low as 1.137V for significant lengths. Have you tried leaving the clocks at stock but turning the power limit all the way up?

Here's my log file - you can see it only hits the limit a couple of times.

This is @ 3515 max boost memory.

See where it dips? Sometimes heaven gives accurate scores...sometimes the scores are much lower...when the scores are accurate there is no dip...Is this evidence of too high memory clock?
