*** UPDATE ***

So far we can say this about boost clocks for the Gigabyte 570 OC;

Mine: adds 220 clock at any frequency
_jokes_: adds 220 clock at any frequency
Oridin: adds 170 clock at any frequency
rdmx: adds 170 clock at any frequency

My proof;
stock: 980 / 1201

437

_jokes_ proof:
+100: 1080 / 1301

375

Oridin / my proof;
Oridin: +138: 1118 / 1289
Me: +138: 1118 / 1340

416

rdmx proof; (can you verify rdmx?)
+180 1161(suspected) / 1331

429

So it seems that so far there are two lotteries when buying a GTX 670 OC;
* boost clock adds 220 or 170
* max clock varies
It's possible they're correlated but I'm leaning towards not after talking to Oridin. rdmx can pass a test at +180, but I don't think Oridin has.

Also, it seems like my core clock becomes more stable as I raise memory clock, to a point. Clocking core gives worst results when memory is left at zero OC, which is why I think _jokes_ settled at +120: 1100 / 1320 to benchmark games (his screenshots never raise mem clock).
If you're reading this buddy, try again with memory at +550 thumb.gif

Perhaps there is some way of identifying whether or not it's a 220 boost or 170 boost by PCB stickers?
In any case, I'm dying to know, does a 120 boost clock exist? what about a 270 boost clock? sonic.gif

PS: I firgured out what's going on in that 1400 clock screenshot from _jokes_. I believe it's an error and he didn't clear GPU-z log after running a +200 test and crashing.

375

*** /UPDATE ***

I picked up one of these today for $525 AUD.
Someone said it might be useful to make a thread here.

If you have any questions, etc, I'm happy to answer. Here is what I've done so far;

P9252 3DMarks

This is at out of the box settings. I have tried to OC further using gigabytes easyboost software, but any increase to core speed results in a revert back to 705 when I click apply. I think it's not updated for this model yet?

Try using EVGA's Precision. Should allow for easier overclocking. Also, please post a GPU-z validation so we can see what the stock clocks for your factory overclocked card are. Thanks! thumb.gif

Hey, congrats on your new GTX 670!

Anyways, that is a very nice 3D Mark 11 Professional Score!

Isn't that score higher than a GTX 680 at stock clocks?! drool.gif

Really nice, GTX 670 = Faulty GTX 680 (disabled core)?
