He's using -xcl option which is using the hole that AMD left open to unlock Catalyst limits, aka Baggz's Racerx. So yea, you can overclock w/o unofficial and doing this you can enable ULPS.

/XCL eXtends Clock Limits for official AMD overclocking APIs. Which means that it also extends clock limits for CCC or any other other vendor specific tool using official overclocking interfaces provided by AMD. Considering that it is using official AMD overclocking interface, it is compatible with ULPS. This method is equal to flashing new VGA BIOS with extended Overdrive clock limits.
However, this method uses hidded VGA BIOS emulation debug feature of Catalyst driver. Once AMD decide to remove it from driver, it will stop working. It is also necessary to re-extend clock limit after driver re-installation because VGA bios emulator resides in Catalyst registry entries.

They are gone already. Amazon took two years to ship them out and Visiontek only gives 30 days to register. Thus I had issues registering with Visiontek. I consulted with Amazon and they said to return them. I'm happy cuz the two xfx be's and one sapphire I got do 1300+ on the core lol. thumb.gif

Yeah I know the -xcl switch. What I meant was PowerTune, Clock adjustment and Voltage tweak will not play nice without enabling "Unofficial...".

Vague review is rather vague. OC'd it to 1265 core but mem is stuck at 1505, lol wut? No fluke to test the 88% more current? Why bother mentioning it? Did they throw more volts on the card? No mention.

Hi. I'm new on this thread, and it's "theme", and have, three questions for You folks, before i damp into a week long 650+ thread-page march.

1. Is my 40oC idle temp is considered high, compared to Yours' setups. My windforce 7970 is alone installed in midi tower case with 14cm fan serving it's best air right below GPU's cooling. Before I've had SLI 560ti's with two slot space between them. Their "idles" stayed 36 first/33 second.

2. Every 7970 is so great overclock machine? I've managed to reach 1hr Heaven2.5 run on 1200Mhz core with only 0,03V bump.

3. I'm wondering why my 2600k@4.5 with 2133Mhz memory, driving 7970@stockOC reaches only 86 average fps in far cry 2 in FullHD res. bench, when first review of my card i've stomp on, says of about 110fps with comparable setup. (link to review: http://www.guru3d.com/article/gigabyte-radeon-hd-7970-oc-windforce-review/13)

Thanks for the answers, and... up,up, and to work.

That's true, but it still seems to be a nice card so far. And there is that 1800 core screenshot I posted biggrin.gif

I'm not crazy enough to deny that its one badarse card. I just wish these pansy reviewers would get their hands dirty on a card like this. thumb.gif

True enough. I'm still getting two of them biggrin.gif Who wants a brand new 7970 DCII for cheap(ish)? As an added bonus, we've made sure the VRMs hit 95C under load, so you don't have to decide whether you'll overclock or not!

More seriously, I'm going to lose money on this :/ But I'd rather be out a few hundred than have a card with such insane VRM temps. The main problem for me is that if I sell it internationally I have to lower the price substantially because of the jacked up prices here.

Have you owned past versions of Lightning? Single 6970 gave me so many trouble with using it... Regardless how much voltage i've sent to core or which driver i've been using.
I've selled it right away to some poor soul. devil.gif
Singled card was far from stable with OCZ 1000W PSU, which droved perfectly 560tis' SLI at, even 8h long, Skyrim Runs(average load about 80%, all eyecandy mods, oclussions High), which is also perfectly feeding current 7970.

Guys, anyone here play World of Tanks and have problems with HD 7950 or HD 7970, sometimes i can play for long time without problems, but sometimes i get dirver crash within minutes, also game glitches all over the place, even on stock clocks, i tryed Metro 2033 and 12 loops of crysis warhead (8XAA) and it passed ok. Is this driver problem or game or something else.
Cheers
