I've noticed the same few times. Restarting Afterburner fixed it. Monitoring graphs bug the same way. Again, restart fixes it. Seems a small bug in the afterburner.

Nice review. I am sitting here with 920 @ 3,8GHz on Asus P6X58 Deluxe mb which have 2x sata6 and 2x usb3. So for those I dont need the upgrade. Performance increases from Sandy -> Ivy -> Haswell are really disappointing but I am still leaning towards upgrading to Haswell now. Z87 mb's look nice...

I had 7970 DCII with similar issues on 1440p CrossOver monitor. I tried different DL-DVI cables. Some worked better and some worse but I couldn't get rid of the issue totally. So I had to return the card with refund as at that time there was no known fix and other users reported similar issues...

Could be bad quality DL-DVI output from the card or low quality cable. Example Asus 7970 DCII have also the same issues, only then the pixels flicker green. The issue is only revealed when used DL-DVI link with 2560x1440 or 2560x1600 displays. I suggest that you try good quality cable. That got...

Note that if you're using 12.11 beta 3 or 4 drivers its common that 300/150 clocks do not work because of some driver bug.

In open case vapor-x's (just as reference because then the air flow is similar in each case) gpu stays at 65C and vrm 75C under Unigine Heaven bench. Clearly there was some bad patch. Maybe they forgot heat tapes between vrm heat sinks.

Interesting to hear about bios error (even though that might not be the real reason). I've 7950 vapor-x and the default non boost bios with 850MHz clock was unusable because the gpu voltage raised under stress up to 1.25 which caused overheating and driver reset. I changed to the boost bios...

Just small update considering 7950 vapor-x. Latest trixx 4.4.0 beta supports voltage adjustment without needing to force constant voltage.

Just installed my 7950 vapor-x and have to say I am disappointed at the noise and the heat. Unigine Heaven run raises the temps to 85C when the whole system crashes and fan blows at 70% which makes really nasty noise.. not sure whats up with the card. I've not even used the overclock button...

I just packed up my voltage locked 7970 DCII TOP for return. While doing that I checked how well the heat plate was seated and noticed that some of the screws were not tight enough. Few memory chips which I could see didn't make contact to it but had ~½mm gap. Also card wasn't straight but...

Little driver speculation before 79xx "XT2" chips are released: In Guru3D forums Unwinder (writer of RivaTuner and Afterburner) commented: "Unofficial overclocking mode is completely gone with new drivers, old libs no longer work. So use official mode and stay within CCC clock limits. Thank...

I am thinking that there are slight differences on the board itself. Mainly on the controller chip which might be different on voltage locked cards. This would explain why voltage reading or changing it with afterburner doesn't work for these cards. If that's true then different bios wouldn't...

Only programs that can even read the gpu voltage are gpu-z and asus gpu tweak. I doubt the gpu-z even reads the voltage really as it is just constant 1.170v without any fluctuation under load. Asus gpu tweak shows 1.142v-1-162v under load (furmark). I can lower the voltage from gpu tweak but not...

I've personally tried so many different versions of radeon drivers, asus gpu tweak, sapphire trixx, msi afterburner and even did clean install of windows 7 and windows 8 consumer preview but with no affect. I also tried with exactly with the same versions of drivers and gpu tweak as fellow 7970...

ASUS 7970 DCII TOP ASIC 65,2%. This is with the "new?" dreaded voltage locked bios with default voltage of 1.175v which cant be increased (atleast for now). Max stable gpu 1130MHz with 1660MHz mem.

I solved the green pixel problem with new DL-DVI cable. Seems 7970 DCII is more picky about the cable quality than most cards.

I just installed ASUS 7970 DCII TOP as replacement for ASUS HD5850. I'm using 27" 2560x1440 DVI-D Display. The problem is that the Dual Link port gives randomly flickering green pixels all around the screen. I've googled about this and seems I'm not alone with this problem. I'm starting to think...

http://www.youtube.com/watch?v=Jcfbsy1SKTM Here is a video posted by ASUS showing the GPU Tweak softaware in action with 7970 card. There you can see clearly that the gpu voltage can be changed up to 1.250v. They dont say in the video which 7970 card is used: reference, DCII or DCII TOP but I'd...

nVidia could easily cut prices if needed as I think the margins are wide now. Compared to 79xx's the gk104 chip is smaller, less memory on board, much simpler pcb (specially on ref. 670) and less components needed overall. For AMD it would be much harder to push prices down from where they are...

This isnt the 1st time I've heard about this and I am curious is it true as I'm wondering should I get GTX 670 DCII (already preordered) or 7970 DCII TOP which I can get cheaper here in EU.

All the blacks are distinguishable and white saturation till 252. This is with 0 brightness and 100 contrast set from monitor. Contrast from video card drivers are set to: R:86, G:88 and B:88. With those settings I get no tinting which is common to this monitor when using 100 contrast (or values...

I've got my ZR24w for a week now and here is my thoughts about the display (camparing to Benq 22" E2200HD 2ms and Samsung 27" P2770HD 5ms which both are TN panels) + low enough input lag even for some fps gaming + some trailing on fast movement but good overall + great colors + good stand...

I ordered mine with that extra warranty as its so cheap from finnish retailer just under 400€ shipped. I'll post my impressions after I get the monitor tomorrow. Comparing it to Benq 22" E2200HD which is with TN panel.
