<b>*** UPDATE ***</b><br><br>

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

Mine: adds 220 clock at any frequency<br>

_jokes_: adds 220 clock at any frequency<br>

Oridin: adds 170 clock at any frequency<br>

rdmx: adds 170 clock at any frequency<br><br>

My proof;<br>

stock: 980 / 1201<br><br><a class="bbcode_url H-lightbox-open" href="http://cdn.overclock.net/e/ed/ed0f34ca_capture22.jpeg"><img alt="437" class="bbcode_img" data-id="865515" data-type="61" height="437" src="http://cdn.overclock.net/e/ed/600x437px-LL-ed0f34ca_capture22.jpeg" width="600"></a><br><br>

_jokes_ proof:<br>

+100: 1080 / 1301<br><br><a class="bbcode_url H-lightbox-open" href="http://cdn.overclock.net/7/77/77fcee11_ORdSZ.jpeg"><img alt="375" class="bbcode_img" data-id="865505" data-type="61" height="375" src="http://cdn.overclock.net/7/77/600x375px-LL-77fcee11_ORdSZ.jpeg" width="600"></a><br><br>

Oridin / my proof;<br>

Oridin: +138: 1118 / 1289<br>

Me: +138: 1118 / 1340<br><br><a class="bbcode_url H-lightbox-open" href="http://cdn.overclock.net/8/8e/8efa825f_20027.jpeg"><img alt="416" class="bbcode_img" data-id="865529" data-type="61" height="416" src="http://cdn.overclock.net/8/8e/600x416px-LL-8efa825f_20027.jpeg" width="600"></a><br><br>

rdmx proof; (can you verify rdmx?)<br>

+180 1161(suspected) / 1331<br><br><a class="bbcode_url H-lightbox-open" href="http://cdn.overclock.net/f/f6/f671c87c_HqzMu.jpeg"><img alt="429" class="bbcode_img" data-id="865530" data-type="61" height="429" src="http://cdn.overclock.net/f/f6/600x429px-LL-f671c87c_HqzMu.jpeg" width="600"></a><br><br>

So it seems that so far there are two lotteries when buying a GTX 670 OC;<br>

* boost clock adds 220 or 170<br>

* max clock varies<br>

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.<br><br>

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).<br>

If you're reading this buddy, try again with memory at +550 <img alt="thumb.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/thumb.gif"><br><br>

Perhaps there is some way of identifying whether or not it's a 220 boost or 170 boost by PCB stickers?<br>

In any case, I'm dying to know, does a 120 boost clock exist? what about a 270 boost clock? <img alt="sonic.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/sonic.gif"><br><br>

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.<br><br><a class="bbcode_url H-lightbox-open" href="http://cdn.overclock.net/1/12/12142fa9_CBHFg.jpeg"><img alt="375" class="bbcode_img" data-id="865528" data-type="61" height="375" src="http://cdn.overclock.net/1/12/600x375px-LL-12142fa9_CBHFg.jpeg" width="600"></a><br><br><b>*** /UPDATE ***</b><br><br>

I picked up one of these today for $525 AUD.<br>

Someone said it might be useful to make a thread here.<br><br>

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

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?<br><br><a class="bbcode_url H-lightbox-open" href="http://cdn.overclock.net/3/3a/3a8b49e5_p1050682u.jpeg"><img alt="450" class="bbcode_img" data-id="861835" data-type="61" height="450" src="http://cdn.overclock.net/3/3a/600x450px-LL-3a8b49e5_p1050682u.jpeg" width="600"></a><br><br>
