[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 1472

Will this work on my Sapphire hd 7950 dual fan ?

If it's the ref OC edition, most likely. But, your 2nd BIOS is already set to 900Mhz stock. No reason to use the new powerboost really

Is there a fix for crossfire in sleeping dogs?
Edit: Also, anybody know what is wrong with radeonpro?

gave you a direct answer just now.

So are you saying that if the game has broken vsync, you cannot force vsync via 3rd party now?

It may slow down your base clock speed.


Also if you run your card faster than what this new BIOS will push it it may not really be worth bothering to upgrade to because you are going to slow down your card.

Yeah good point.
Stock clock is 900mhz and OC is 1130mhz ...
Only running OC when I play games that need it though, but since my stock is 900mhz anyway I guess I'll just stick with current BIOS

Got my Open Box Sapphire 7970 (Dual-X Overclocked) today and ran some tests. The PCIe bracket was all bent--I still can't screw it in properly--only one screw, and at a 45-degree angle or so. I have no idea what some of these companies do with the cards when they are returned, but the bent bracket deal seems not uncommon =/ Despite my best efforts to straighten it out, it appears to actually be inserted at an odd angle to start with, which makes me wonder if it was returned for that reason.

Here's Heaven 3.0 at stock settings:



And here's a re-run at 1125MHz core clock, 1575MHz memory clock, +20% Power Limit, and I actually increased the voltage to 1150mV to decrease artifacting (though it wasn't crashing without the increase).



What I am noticing is a lot more screen tearing (without vertical sync) in Heaven, and also rather unsmooth brightness gradient transitions, and periodic artifacts here and there, versus my GTX 670. The 7970 gets a higher score, but my GTX 670 does a lot smoother runs, and FPS in Heaven 3.0 doesn't vary as widely between different scenes as it does on the 7970.

I am using Catalyst 12.7 Beta. Is it just something off with my open box card, or is this normal?

Not sure if I should try Gigahertz BIOS vs. standard overclocking (if I even can with my card). Also can't figure out how to get the card to run at something higher than 1125MHz core clock using MSI Afterburner. Can only seem to do it with Trixx, but I can't see any voltage slider, even after disabling ULPS.

P.S.: This card is going to be on my family member's computer, and he plays WoW time to time. I logged in to check FPS there, and it's dramatically lower than it was with the GTX 670 (which I'm going to use for my mini ITX build, as it's a smaller card). I know there's an nVidia bios in WoW, but I didn't expect it to be so strong! Considering that this card is supposed to be more powerful. But again, maybe there's something wrong with my particular card, as it is after all open box and perhaps even refurbished in some way.

I get my 7970 tomorrow. UPS is delivering a day early. I cant wait to get my rig running again. Its been a LONG month

After fresh windows installation i had black screen and 100% funspeed while updating battlefield 3.I am using catalyst 12.8 .I didnt have a single problem with 12.6
