[OFFICIAL] GTX 670 Overclocking

post #1 of 1562
Thread Starter 
It seems people are posting their results everywhers. So, therefore, I've created this thread to mostly compile a list of results, and of course have a discussion on all things regarding overclocking the GTX 670. When posting please provide:


Card Model
OC Software
Max Core Clock
Max Memory
Max Stock Clock (optional)

PROOF (3DMark, GPU-Z, etc.)



Good idea of how to oc, tweak, and general rules can also be found here (thanks to SeanPoe):

I'll start...

GIGA 670 OC WF
EVGA Precision
Max stock: 1215
Max OC: 1280 (stable)
+65 core
+500 mem

Gigabyte Winforce -
Stock max speed 1137

Current Max: 1205 frown.gif

It was 1225 but I maxed out Heaven and it crashed / OCCT also crashes the card @ 1215 so I'm thinking 1200 is stable.

1215 does work very well in BF3.

bumrush,

ouch, that sucks! anyway, you might want to revise the post and mention what OC software you're using...as well as what memory clock

I'm not complaining.. It is what is.. This card stomps all over my dual 6870's, both in terms of micro-stutter free performance and being able to enable 4MSAA.

Tool:

MSI Afterburner

Memory offset +200
GPU Offset +65

Stable clock - 1205

Are you guys stressing this card to the extreme? Mine only crashes at 1225 if I set Heaven to Extreme tesselation, 4 AA, 16AF 1920x1080 or use OCCT.

Kombuster seems to be kinder to this card, though, and BF3 gives me the illusion that it is fully stable.

I'm not worried, once I'm done enjoying the speed of this, clocks are going back to factory and adaptive vsync is coming on for the ultimate visual bliss

BUMRUSH, well, it is a 915MHz card OC to 980 boosting to 1200MHz. That extra 100 is not going to matter, because by the time I really "need" it, I'll be buying another card. It is a great card, and 1.2GHz is still fast.

Exactly what I was thinking myself...originally I was pulling my hair out, trying to decide between the Asus or Gigabyte....the Asus is still not released yet, only review sites have them...so its hard to get an idea of how they really perform in the real world (general average)....the Gigabyte is proven, available to order, and plenty of people have them...there are a few who can't seem to OC above 1250mhz, but who cares? New cards will be coming out when you need that extra "oomph"

My GB GTX670 OC overclocking info:

Stock Core Clock after 'Kepler Boost:': 1189MHz

(Apparently) Stable Overclocks So Far (lots of benches run w/o crashes/artifacts)
1) 1345c/3225m (1.162V)
2) 1325c/3600m (1.162V)

The frequencies are all actual 'observed' clocks via AB graphs during bench runs.

Drivers: 301.25

Max Voltage can be raised to 1.175 in Precision X, but won't budge over 1.162 in AB even w/voltage slider maxed. I've NOT tried OC'ing at 1.175V yet but plan to try it out in the future.

I'm also going to be running various benches to determine which of the two OC configs I prefer ... but I'm very much leaning towards the 2nd one as the better of the two. It seems worth it to lose a little core to gain a ton of memory bandwidth.

At these clocks, my temps get up to 62-65C after running for long periods at 99%.

I don't know what the fan speed is (my guess is the 45% range) but I'll tell you this ... my case runs VERY quiet as all my fans are on controllers ... and I absolutely cannot hear the card at ALL ... even after 20 minutes of benching Heaven maxed out. Not even thinking of making any fan profile, the one that's on there now works perfect.

I'd guess that at 1.175V it might be a little different but I'm pretty damn happy what this card does, in terms of noise, clocks, and temps at 1.162V so I doubt I'll push it any further, at least not for 24/7 use ...

My max observed temp is 65C on load, typically runs at 62-64, and card idles around 33C.

Aren't the 301.34 the newest drivers? Good numbers. Also my power target never seems to go above 100%.
