I want one so bad.... The Gigabyte 7970's seem to be out of stock everywhere. Anyone know when they'll be in stock again?

1600MHz or 1600mV? 1600MHz shouldn't take more than the stock voltage of 1600mV. tongue.gif

If you keep turning the memory clock up and the performance stops increasing you've hit the point that the error correction hit caught up with the performance increase. At that point you'll either need to bump the voltage or back off the clock a bit. Go too far past that point and you'll notice things start stuttering.

1700 for me. Above will lock up.

1700 mhz memory on 1.615v all day, OEM is 1.6v. I have a fair amount of headroom left with the memory, I am thinking 1800+... but msi afterburner is limited to 1790 so we will see.smile.gif

In my opinion it's absolutely ridiculous that they released a $600 card that they can't support. It's even crazier that they released a new driver version after the card was released and it STILL didn't support the new card. Insane. Imagine if LG released a new tv that didn't work with Comcast, or if the next iPhone didn't support any 3G or faster connections.

I agree we need a better driver soon and now that the 7950 are out they should release something. I also just noticed when I just tried to check the AMD site for a new driver the 7 series driver page is down and been down for at least 1 day that I know of whats going on

Anyways, I'm off work and it's time to dive back to the stable overclocking on my card. So far, I think I'm pretty stable at 1175/1650mhz. My memory overclocking seems to be fine but I want to get my core up to 1200 like I can easily on my first card. Adding too much voltage will not be stable, not adding enough obviously will not be stable so I have to find the sweet spot.

I uninstalled Afterburner as it seemed to be buggy with my CCC. The power slider wouldn't stick, or it would stick for one card and not the other and all that. The voltage/clocks wouldn't appear or show up despite having ULPS disabled things like that.

Got rid of it and installed Trixx and it's much easier on the eyes and does everything you need it to and doesn't seem to conflict with my CCC at all.

Awesome, glad i bought the pro AX850 and not the other, higher wattage more expensive versions.

OFF-question: Did you ever play a single 7970 on the U2711?

After u have successfully created a bootable usb/cd... put the ATIflash.exe and ASUS3D.100 file on there, which is also found on the second post as a zip file.
EDIT: Oh yeah...and what ken said, i just read the first few words and compiled this guide. lachen.gif

Hello. I am struggling overclocking my Sapphire HD 7970, @@ how can you hit the 1250Mhz @ 1.225v ?@@ To me the wall is 1200Mhz, I can not go any futher it will crash even at 1.3v:o . I really followed your instructon, Here is what I did:
1.First manully flashed to Asus bios.
2.Asus voltage tweak set to extend overclock enhancement, but not run it when overclocking
3. Afterburner set to 1.25V and 1250Mhz, 1700Mhz for meory and at 1.7v
4 unselect CCC overdrive, but set the values in it same as afterbuner
5.only use AB to overclock.

So this is all I did, I know you can go even 1300Mhz but to me 1200Mhz is the wall, but our cards are all Sapphire brand, did I miss something or just my card is werid?@@ Sorry I am new to overclocking, I really need your help, I see your post result that is amazing! please help me out with this>< really appreciated man!smile.gif
