The sad thing is, I get both low overclocking headroom, and low kepler boost (aka out of box boost)....if I gotten a card with 1100-ish out of box, then +100, then it wouldn't be so bad, as 1200 is considered the norm for 670's

So just finished reading the overclocking thread/guide listed at the beginning of this guide, and my results give me many, many sad faces. I have the Gigabyte Windforce gtx 670, and with everything at stock (power target and voltage both at max), using Precision X, using current drivers, my card gets up to 1110Mhz. This gives it a Kepler Boost of just +41. The card has yet to break 65C, so no throttling there. I have finished the core clock overclocking and, using Heaven as a bench, I have maxed out at +75, or 1185Mhz. Memory I have yet to test yet, but man... did I just get a crappy card or what? rolleyes.gif

Maybe give MSI Afterburner a go I found I had higher stable clocks with that, some have no issue's. Again anything more than advertised is better than nothing

I'll give afterburner a go, just passed +300 on the memory and I'm working it up.

EDIT: Still stuck at max 1185Mhz on the core, but managed to get +700 on the memory without problems. Quickly looking through this thread, that seems high. It is high? tongue.gif

is your card tapping out at 1185mhz? can't hit 1200?

its certainly on the lower end of the spectrum for a WF3 model....but fear not, I may have possibly the worst 670 out there. 1045 stock, +100 and no more, or else it cries uncle....so 1145 total

:O while that certainly makes me feel better about mine I must say I am sorry you got such a chip. So I managed to get a max OC of 1185Mhz on the Core and 3702 (+700) on the memory. The Gigabyte card is extremely quiet and cool, and although mine doesn't have the highest ever clock speed it does what I need it to do.thumb.gif

I got one to nearly equate with yours. Just got my EVGA 670 FTW and it can't even get past 1166 Core maximum. Anything over +50 Core will crash the drivers when even loading Heaven. ASIC is a dreadful 76.6%...

Noting that yours wasn't even a binned chip shows that yours is pretty solid, while mine was suppose to be "binned" and it appears to be an OC dud...

I can run +700 in unigine, but it makes me a little uncomfortable considering i have no way to measure the temperature of the Vram. My 24/7 OC has the Vram set at +600 which results in 3602 MHz (7204 MHz effective).

I also don't see you getting much gain out of +700 on the memory unless you can get the core clock higher. Core clock and Vram clock should increase with one another. Having one high, and the other lower, is not efficient.

High vram can hurt you. Check 3DMark under detailed benchmarks for framerates, especially your CPU and combined score. I lost 10fps at one time going to 600 instead of staying at +450.

I noticed that too. I thought it was pretty strange. Does that mean the card's unstable or does high memory clocks just work like that?
