gigabyte hd7970

[mob bob]

hi, are the ghz and the non ghz hd7970 from gigabyte the same card but different software ?

 

[wazza300]

same apart from the clocks,ghz=1000mhz core non ghz edition usually means slower 900mhz or round abouts

the gigabyte 7970's are voltage locked so don't buy them if you want big clocks

I have 2 of the ghz editions and neither go above 1050mhz.

the voltage lock problem is not a really big concern to me since I am new to overclocking.

I would like a mild overclock for stability.


which is the best hd7970 for stable overclock, no voltage limit, or just wait ill the new 9000 series comes out ?

the good thing with being voltage unlocked is you can lower it for cooler temps, im stuck @ 1.25v with my wf3 7950

A good 7950/70 should do 1100mhz with 1.25V

I got my hands in more than 20 79XX series cards that I could test...

All of them could reach 1100mhz with 1.25V or less, the best one was a Reference 7970 Sapphire that could do 1200mhz with 1.17V.
