Whats the general consensus here? At what speed does the 7950 match a 7970, and do you really getting timings improvements from flashing to a 7970 bios?

I've never really gotten on board with the whole, get an X because it beats Y if you OC it. But if you got Y you'd OC it. I think comparing an OC'ed card to a stock card is kind of pointless because it has nothing to do with the reality of you overclocking whichever card you buy. In this case an overclocked 7970 dominates an overclocked 7950. I mean, this is an overclocking board, so stock performance is kind of useless even considered by itself.


In other news, my XFX black edition 7970 was giving me coil whine and had given me some artifacts in Heaven dx9 at stock so I got the new Gigabyte triple fan 7970 to replace it. I got the gigabyte yesterday and played around a bit, planning to return the xfx today. Both cards have the exact same coil whine under the same circumstances. I mean same exact pitches and loudness. Somehow the Gigabyte seems to put out a lot more heat than the xfx, or the xfx does a much better job at dissipating it. The Gigabyte is considerably louder as well. The xfx will hold temps in the low 70s while the Gigabyte will hold temps at 60 so the fans will generally be running much faster while the pcb also feels much hotter. I think I'm going to keep the xfx even with its quirks.

Bad luck you got two coil whiners. But kudos for not being like: "my cardz wont make 1200 OMG teh horrorz going 2 RMA!"

You making fun of me since I am having a tough time getting stable on one of my cards and thought about sending it in for replacement as 90% of them can reach that without a lot of effort?

Yah think I was. RMA is for products that fail (or show anomalies) at stock(-clocks, -voltage). Not for products that don't reach a satisfactory OC.

HI guys~ I just got a Sapphire HD 7970, I tried to overclock over 1200Mhz, but I just can't ;( even with 1.3v in AB, and btw I also upgraded my bio which is the ATI automaticlly one, then use CCC with AB. I have no idea why I just can not get 1250 @@ Actually my setup is pretty same with 'n3tr0m' except I only have one card. SO any advise Pls...........>< thanks in advance!!

The XFX actually does OC over 1200 and is fine in all games and benches except Heaven dx9 where it goes bonkers at any speed until I restart my comp. I figure I'll just take advantage of the xfx lifetime warranty if it dies.

I also messed around with xfire for about an hour but it put out such a huge amount of heat and noise that I quickly decided it wasn't for me. While under load my comp sounded like a vacuum cleaner and the temps were really high. I'm not sure how you xfire guys deal with it.

are you sure it's not your PSU producing the coil whine? seems pretty coincidental that both cards produce the exact same whine under the exact same circumstances.
