Here is a great guide to kill all the boarder issues with AMD. Just dealt with it in some games that drop me to 50hz.

thanks for the guide thumb.gif

What do you mean, I should get the power color ones? Or I should seek for a used one capable of doing 1300Mhz?

Playing at 75Hz on Crysis leaves me with a good two inch boarder around my screen but if I drop it to 50 i get full 1080p.
Edit: This is on HDMI though..

create a custom resolution on CCC...
I have 1920x1076 just for crysis games problem solved... No more 50hz bug...

try putting your resolution in the desktop and use the overscan feature and get that fixed..

The BIOS is different But there is a piece of hardware missing from the equation, if the PCB is the Reference design, then there is no reason a 7970 GHz edition BIOS wouldnt work on a 7970 Reference.

I wouldn't say it was a hardware change.....If I was to put a guess on why the ghz bios/core boost doesn't work on the fist gen 7970 it would be on the fact that the bios has been written specifically to determine a unique serial or code within the GPU or something within the updated card (like a mac address for your wifi for example). As the first gens code would be different to the revised code, the boost feature would fail to initiate and unlock the full features and allowing only the basic access.

Of course this is purely my speculation on the situation and i could be completely off the mark...but with my knowledge in engineering I would confidently say that it would be pretty insane for a company like AMD to make hardware changes so late in the year, especially since even the slightest change in hardware would cost them $$$$ due to needing to redesign the production line to incorporate + the additional costs per part etc. From my experience it would be far better to pay a bunch of software engineers to develop a bios that is specific to a card with a different integrated serial than look into a hardware specific lock.

Like I said this is only my opinion and I could be miles from the truth...I guess we will find out soon enough + If it is software locked, it could be cracked tongue.gif

What I mean is that you have a goal of matching four cards at 1300mhz. You have two out of four already. Thus there's no time like the present to start on that goal because waiting for ghz cards will not help you in this endeavor especially with their different bios with the lame boosting. And on top of that it doesn't necessarily mean that the ghz cards will hit 1300mhz. All signs point to the exact same silicon, just slightly dolled up with a new bios. LOL.

I need your opinions . (Again)

Prices are dropping again - at least on the Diamond, so hold off for a few days (week most)

I don't think they will drop by much, anyway, I already pulled the trigger yesterday on the PowerColor.

I bought 4 x 7970 + 4x EK F7970 EK En nickel with a quad bridge. I also have customs backplates from DWood

Is it just me or does DVI give better image quality compared to HDMI and takes a lot less setting up on the sharpness and so on?
