Neil,
Have you tried the hack listed here?
Not sure if it will work for you, but maybe worth a try. The overscan for ATI/AMD is almost always set to around 10% for me when I install on a clean system, but since I have access to CCC, it's easy to change/fix. I haven't run without CCC that I can remember.

As far as pro Radeon or Nvidia, I've used both and both are decent and have their pluses and minuses. I personally find that the Radeons run better in general, but that could just be the way I run them. People do seem to get polarized towards one or the other, from what I've seen...

If you're saying that the image doesn't fill the screen edge to edge, have you tried going into Catalyst Control Center, and under "My Digital Flat Panels", choose "Scaling options", then move the slider over to the 0% setting?

My 7950 is currently showing 35K RAC, so I would think a 7970 could do more than that...

Sutaru,
you can check out this host for performance of a HD 7950, it's a Sapphire Vapor-X running at 950/1250 clocks (stock for this card), 2 tasks at a time, on an i7 3770K running 5 CPU tasks at once (three free threads). CPU is running at 4429MHz, though it reports 3500 in the stdout in the tasks.
My whole system, including the 27" LED monitor, is using 280W on average according to my UPS.

HTH,

It looks like you have 7 CPU tasks, 2 ATI V7s and 3 Nvidia APs all trying to load, my guess would be you don't have enough free CPUs configured. Try limiting it to 6 CPU tasks at a time.

Plus for those that want to water cool their video cards without being expensive, one could use an asetek made cpu water cooler on their video card with this [link cut], on [link cut] the bracket is about $20, this will work with the Corsair H50-110(excluding the H80 and the H100), the Antec Kühler 620, 920 and the 1250(New model), the Thermaltake Water 2.0's(all 3, the Pro and the Extreme, plus their baseline model) and any other cpu water cooler that uses the Asetek made pump... Oh and the case is an NZXT Phantom 530 for about $130.00... The two cards are Nvidia Titans...


I don't know about the other coolers, but I had an H50 strapped to an HD 6970 for a while with zip ties, and there's no way it's going to be as low profile as any of those picture links. I have some H70s and an H100i, and they're all a different sized head unit, so maybe the H50 - 110 is a typo? The H50 is at least a 3 slot solution, and probably more like 4, though I only used it on a single card, so I can't say for sure. But the pictures you posted make it look like a 2 slot solution. That it's definitely not. And as a GPU cooler, it kicks some serious butt, but it won't cool anything else, ie. VRMs.
Oh, and the zip ties, probably 20 - 40 cents. Beats a $20 bracket hands down every time....

-Dave


No the H50 is no short pump, from the H70 on they are very short, I'm using a Corsair H70 now on My cpu, I'll eventually upgrade to a Thermaltake extreme water 2.0.

Thermaltake Pro water 2.0(120x120x50mm)[left], Thermaltake Extreme water 2.0(240x120x50mm)[right], Link to guru3d.com where more info on these two coolers is at.

Now I didn't say that the H50 would take up just two slots, I said It was capable of being mounted on a card and some people have done just that, now as to the vrm's the bracket is for either a 92mm fan or an 80mm fan, now I don't know how many slots the card takes up, but then all I can tell for sure, is the motherboard is an Asrock and NZXT is saying the temps are 30C lower than the stock Titan cooling solution, I've also seen mentioned temps of 53C, which is not too shabby. The link below has a couple more pics and some text.

http://www.guru3d.com/news_story/nzxt_vga_watercooling_solution_at_computex.html

The following is a bracket kit that costs all of $6.00 or so depending on the model(there are two brackets and they both come with screws and such) by a guy in His spare time as a hobby Here.

One can use the stock cooling with the pump, as this is what PNY did with their 857MHz GTX580 card and a radiator, which I assume nothing about as I have direct knowledge beyond the fact that this does work.

GTX 680 installed with the fan model, there is room underneath for heat sinks if you want them.


Ok, I was just responding to your post saying "the bracket is about $20, this will work with the Corsair H50-110", and looking at the picutres you linked to.
I know from my experience that you can mount an H50 to a video card for under $1 in zip ties and that the space it will take up in a system is nowhere near what would be indicated by the linked pictures, that's all. The lower profile head units would probably fit as the pictures indicate, just a guess.
Can't comment on specific cards, as all I've done it on is an AMD 6970, but the cooling was fantastic for the GPU, but the rest of the card had to rely on ambient conditions for the VRM cooling, which was OK IMO, but I mounted a bunch of heat sinks to the chips.

Post:

If I look at the properties tab in Boinc Manager for Seti, it says

Don't fetch tasks for AMD/ATI GPU : Project has no apps for AMT/ATI GPU

It would appear that Boinc thinks there's no valid application available.

Anyone have any ideas on anything I could try to get Boinc to recognize that there is/are valid apps? Would making an app_info get around this? If so, what would be the app name to use in it?

It's still not requesting work...
It was able to do work all last night, but didn't even request any.
I'll set it to do work while active and see if that gets any work.

-Dave

[edit]
I enabled all processing (CPU and ATI GPU) and set it to do work while the computer is in use, updated, and just got 73 CPU tasks, I am not seeing any
request in the messages for any ATI work. I waited for all the transfers to complete and did another update to see if an ATI request would happen, but that update did another CPU request and got another CPU task.

[edit2]
I enabled <work_fetch_debug> on this machine and I'm seeing this in the log file:
6/2/2013 11:00:38 AM |  | [work_fetch] Request work fetch: Core client configuration

So I think something must not be configured correctly on my end?

Other info that may be helpful, I'm running stock apps, Boinc 7.0.64 and Cat 13.4.

I even set my prefs to do

CPU - NO
ATI - YES
NVIDIA - NO

in hopes this would
force the matter, but that doesn't seem to have worked, either.

Something must be missing or mis-configured, I'm just not sure what...
