Hey WelshBloke if you don't want it I would be willing to swap a GTX 460 + Money for your 6950 .

I recall when 60c + idle was the norm (on single cards/monitors). Still have a few old cards in other machines that idle 60-63. The idle is no prob, just focus on the load, even at 95c should be OK, although I'd look into ways of bringing it down.

My eVGA 9800GT idle temp was 65c & load was 85c.

My current XFX 6950 is pretty much the same, idle 62c and load 85c.

I just wasn't aware that enabling multi-displays caused the temps to increase.

I did disable the second display on my 6950 and sure enough my idle temps dropped to 45c.
While 60c is a bit warm, running my 9800GT for 3 years with 2 displays never gave me any problems.

I don't see that changing with the 6950, the card has been solid with no problems.

Afterburner cant downclock this card (at least not for me) and it gets updated more often than rivatuner (I think).

Thats pretty much what I did with my old card (or rather the card I'm going back to).

OK, but Afterburner has a higher limit than Rivatuner does. Give Rivatuner a try and let us know how it goes.

Just to add some numbers for another video card:

GTX295 (stock speeds) with latest WHQL drivers, one 1092x1080, and one 1400x1050 monitor. Idles at 51C with 1 monitor, 59 with both attached (Win7 desktop). 8deg C difference in temp with both monitors attached on one of the GPU's (only uses one GPU at desktop and the other alway idles at 51C also). GTX295 is not exactly a cool running card.

Since both AMD and Nvidia have crappy support for mis-matched dual screen setup.. why don't you opt for Matrox?

Oh wait..

Doesn't seem to want to work with this card, all the overclocking tabs are missing.



Edit: Before you even check what I wrote below: when you go into the Low Level System Settings menu, did you click the box that says "Enable low-level hardware overclocking"?




Did you go to the Power User tab and enable ATI OVerclocking?

-Go to Power User tab
-Scroll down to Riva Tuner\Overclocking\Ati and open it up

My settings are as follows :

EnableBIOSParser 1
EnableBIOSParserTunings 0
Driverlevel3dclockcontrol 1
Driverlevelclockcontrol 1
EnableMPLLReset 0
ReferenceDivider 0
Showeffectiveclk 1

Everything else in that tab is off.

Good luck!

I'm curious about these issues with higher temps and no downclocking with dual monitors. I've never heard of it before, and I've been running dual monitors for 5 years, and haven't noticed any problems with the three cards I've had in that time frame (GF7800GTX, GF8800GT, HD5850).

As I sit here my 5850 is idling at 44C with the GPU clock at 157 mhz. Disabling my second monitor resulted in no changes to temp, clock speed or fan speed.

I have a HD6950 that's supposed to be getting here tomorrow... we'll see how things go with it.

Are they equal resolution? It seems to be only an issue when monitors gave different resolution?

I was looking back at your post earlier and your clocks seem all over the place.

Can you clarify what card they were for and if you had manually downclocked them (and what you used)?

If your 5850 is idling at proper 2d clocks with mismatched monitors thats great news and I'll probably get one after the 6950 goes back.

I'd be really grateful if you'd post back with your 6950 experience as well.

Well, I've been running some benchmarks with my new 6970 (overclocked to boot) and it has yet to go over 63 deg C. Idle has been in the high 30's (though it hasn't really had idle time so to speak yet... LOL...) I'll have firmer numbers after a few days for sure. But I highly suspect, as before, that you do indeed have a dud card.

However the driver issue is confirmed. You do have to use the drivers from the disk or the conventional 10.12 driver, NOT the 10.12 preview driver, for the 69xx series cards right now.

Thats pretty awesome!

I've been doing some asking around and it seems like it will be possible to get the clocks down to about 250/700 soon with third party software and Afterburner will have voltage adjustments soon as well, so I'm feeling a little more hopeful.

I'm kind of in two minds as to keeping it and sticking some aftermarket cooling on as the fans a bit noisy for me as soon as it gets to about 34%. (this I'll freely admit is an unreasonable trait I have about computer noise).
I was thinking a Thermalright Shamen or Artic Cooling Accelero Xtreme Plus (could they get any more "rad" with that name?).

I'm also hoping that we get the new version of CCC soon as well as this one is rubbish! It really is worse that the one from years age, that one was ugly but at least you could find everything quickly (ish). It cant be that hard to design a decent UI. One big window, banner at the top, long vertical frame at the left with your major categories and a main frame with all the details of the categories. (basically copy Nvidias layout but keep the sliders that AMD uses)

I've got exactly the same problem as you but I don't want to void my warranty and lower the re-sale price by fitting my own cooler. I RMA'd my current 6950 and got my money back because of this issue (didn't know it was because of the multi-monitor). Now I have to choose between waiting until the manufactures sell the cards with their own coolers and risking that I can't unlock it. Or buy a reference-card again and hopefully I can use a tool like afterburner to clock it down.

Can you verify if it is possible to lower the clocks in 2d when using a tool like MSI Afterburner? That is: lowering it to the normal 250mhz when still having multiple displays plugged in?

I'm very happy with my new 6950. It idles are ~40C, and under load it tops out at ~70c. I love PowerPlay because if I'm playing an older game, I can dial down to -20% TDP and the card stays basically cool and silent.

Loving BC2 with max settings @ 1080p (with 16xAF and 8xAA) at 60fps. GPU usage maxes out at only 60% according to GPU-z.

Ok, as I dove into the 6950 upgrade I'm pretty sure I had the problems with 5850 as well, I just didn't realize they were caused by dual monitors. I did some tinkering to the clock settings that fixed it. I'm positive I can fix it on the 6950 as well, once RBE is updated to support the 6900s (drivers won't recognize the card with a modded BIOS on the current version). I'm hoping they'll update it soon, because it sucks having the card idling at 55-60C on dual monitors when it can easily idle below 40C with one....

I assumed he was joking, unless he wants to pay shipping from the UK!
Haha I was semi-serious, no worries though I got a XFX 6950 for 260$ BNIB and I will test it out as soon as it gets here, now what to do with my GTX 460...

Well, I've had it running 100% and pretty heavily overclocked all night. Idles at ~ 35 C and hottest today is 88 C during over-stress-tests. Still without any problems what-so-ever. Average gaming temp is right around 65 C. And all the while the fan is as close to silent as I've ever seen a gaming card at idle and while playing hard, one of the quietest I've had in the high-end arena. Now if the fan ever did spin up, it can sing some but it has yet to do that. I'll install the ASUS specialty utilities tomorrow which I think allow for more custom fan control settings but honestly, right now, I'm very happy. Overjoyed even. For once in my life, I have the best one of the companies has to offer. Best CPU and best GPU (from AMD).

For those who were wondering, it fit in the case without any issues. This case is open but smaller than many would-be gaming towers but the near 12" card had zero problems. I could fit many in here without an issue. I'm working on an actual performance review compared to my 4890 which will probably be done tomorrow or end of this week at the latest. I just have to finish typing up some material and reformat the images for the web-friendly... It will be in my blog once it's finished (my website).

These kind of posts dont surprise me. I had my hell for almost 4 years with ati x800 xt pe

The hell is not in the hardware but in the buggy software. ATI cant make drivers and they never could even with the all in wonder you get desktop corruption. CCC installs sometimes other times it doesnt,, just a bi*ch. One driver your card is fast other driver things are slow slow.. I never will trust AMD ATI ,, Grab a nVidia card next time and you wont have these problems. Other then that RMA the card. gl
