I consider mine pretty kickass, for sure thumb.gif

I don't think that the out-of-box stock boost amount really matters too much in the overall scheme of things ... unless you're not overclocking.

Hey guys anyone taken their card apart? Whats the deal with this metal bracket thing on the edge? I guess it's the reason why the backplate needs to be dremeled to fit right.

When the cooler is taken off I'm not sure what it does. Supports the heatsink?

I see, thanks for the reply

I just popped in my other GIgabyte 670...boo! Its boosted clock is 1124...the OCD in me is starting to get very strong!! mad.gif

Oh well...I'm gonna try overclocking and see how far both goes....so far I have 1189 on one card and 1124 on another (both stock boosted)....I hope both equally OC well...if not, I'm not too happy!

Lightsout ... the bracket is to support/stiffen the PCB, keep it from bending despite the relatively heavy cooler.

okay so I'm testing out my 1124mhz stock core card....its not even stable at 1200mhz...ahhh!!!

the BIOS for both cards are the same...the serial number is off by 5...so its in the same batch I would guess....I just don't know why theres such a huge discrepancy when it comes to the Gigabyte cards

Well I'm popping in the 1189mhz stock card now...and testing how far that one will go...I have a feeling it will go further like Brett's....I dunno if I should exchange for another one....or try out the Asus redface.gif

Thank you sir. I wonder if it can come off ti install a block/backplate.

And OT damn I didn't even realize that MCA had passed. RIP for sure.

Here is my Giga prepped for WCing:

450


I reused the small part of the stock heatsink that covers the memory as it functions perfectly as a heatspreader. I also added heatsinks to the memory VRMs. As expected, I didnt gain a whole lot. Went from 1305 stable to 1325 stable. It stays ridiculously frosty at a max load temp of 34C running Kombustor for 30min. Need voltage adjust NAO!

post #1008 of 1506
Once we can actually add voltage, I can easily see these hitting +200 core offset & over 1400 core on boost clocks. With water cooling and some luck, possibly even 1500 on core biggrin.gif

Nice. You confirmed my suspicion that water cooling would have little to no effect on the max overclock of these cards. The max temps are pretty funny too, never seen a card at only ~+5C from ambient at a 1325core speed and max overclock.
post #1010 of 1506
So wait, when you guys say "stock" overclock, you mean whatever it boosts to on top of the 980 mhz that it's been factory OCed to? So a "stock" OC of 1189 would mean that the boost adds 209 to whatever the core clock is set to? So if it's stable at say, +150, then you would actually expect to get 259?
