What do the GHZ edition 7970/7950 cards really do?

Thread Starter 
Maybe I'm missing something here, but can't you easily achieve the same performance as a GHZ edition card with a lightly overclocked standard edition card?

You probably could, but it will probably be a little hotter than a Ghz Edition card. They put better cooling on those cards I believe. wink.gif

Huh, well my 7950 isn't reference anyway. I was just curious. If the bios become available for my card, I'll move to the GHZ edition.

thats just not true. In fact the HD 7970 Ghz chips are using higher boost voltage of 1.218v while the original HD 7970 chips use 1.175v and easily overclock upto 1100 Mhz at stock voltage. As for cooling solution that depends on vendor . XFX and Gigabyte use the same coolers as they use on their HD 7970 cards, the DD and Windforce coolers. Sapphire has come with a new Vapor-X cooler for the HD 7970 Ghz and the HD 7970 TOXIC .

OP stick to manual overclocking with voltage tweaking . You can choose the optimal voltage required for your overclocking. the HD 7950 with Boost BIOS uses 1.25v which is a bit too high. So use Sapphire trixx and MSI afterburner and tweak voltage to achieve the best balance of clockspeed, heat/ temps and fan noise

for some vendors, ASUS for example, they are exactly the same card Before & After

it's just a Firmware / BIOS update on the card to boot up stock at 1000 Mhz instead of 925 Mhz

with proper voltage and everything else set from factory

so, if you already own an existing Reference 925 Mhz card, just flash the new BIOS, there's nothing different other than the speed itself, and it's now 1000 Mhz is officially supported as stable
