Not sure why. GPU is reported as CAL ATI Radeon HD 4350/4550 (R710) (512MB) driver: 1.4.1734, and the event log recognises the GPU, so it's not saying 'no usable GPUs found' or anything. The PrimeGrid entries just say that 0 work units were received.

Causes? I've already checked PrimeGrid's computing preferences, so no issues there.

EDIT: Oops, forgot the OS: Microsoft Windows 8.1 Core N x64 Edition, (06.03.9600.00)

Does it show any OpenCL support? Your snippit is only showing CAL support, most projects have OpenCL ATI apps nowadays, What version of Boinc are you using? Does it even do OpenCL detection?

Causes? I've already checked PrimeGrid's computing preferences, so no issues there.

Computing preferences is a Global preference, you set it at one project, and it effects all projects, it shouldn't matter which project you set it at,
PrimeGrid preferences, note there is no 'computing' in it, is a project specific preference, that is where you select the type of work, and the device type that is allowed to get work,
So, did you look at the Computing preferences at primeGrid, or the PrimeGrid preferences, or Both?

Ahh, sorry, I meant both of those pages.

As for OpenCL support, I'll have to take a look at that tomorrow when I'm back on the computer in question. I assume I can use something like GPU-Z to check for this support, yes?

Now, assuming it does support OpenCL, what would be the next step? Asking this now just to get it out of the way quicker, if I find the card does support it.

It does support OpenCL, but only OpenCL 1.0 and only ever in beta stages. You need a pretty old driver for it as well, as later versions dropped support for the old cards.

So start at http://www.hal6000.com/seti/boinc_ati_gpu_cheat_sheet.htm and try 12.1 first. If no support already, you'll either have to go look online if someone has even older drivers, or better just give up. The problem with the older cards is that they also use a different workgroup size needed for the science application to work correctly.

Although Seti does have an application that should work with these older cards, you may also wonder if it's worth the spent electrons. Primegrid does not have support for the older cards, as far as I know. But you best ask on their forums if any of the OpenCL apps support OpenCL 1.0 GPUs.

A pretty subjective measurement, considering that it will still likely run circles around a CPU, depending on the work. You could check at WUprop to see what others are successfully running on that card, I also have an HD 4000 series card and am currently using it on Moo!

Curiously, WUprop shows that people are getting work through for PrimeGrid on both the HD 4350 and 4550 as well as the 4670 (my card). However, since I'm not running that project I can't give you any pointers as to what version of the driver, etc. you should be running--I am using the latest one. You might try the PrimeGrid forums, since they know their project and its applications a lot better.

I wouldn't trust GPU-Z to whether OpenCL support is there or not, I've seen false negatives there before, better to use GPUCapsViewer, that will show far more detail,
The easiest method is to just restart Boinc, and look at the Event log, and post the first 30 lines or so, that will show whether Boinc can detect OpenCL for the device,
and it's Boinc that needs to be able to detect and use OpenCL, it's entirely possible for support to be on a computer, but Boinc being unable to detect it.

A 4350 only supported BETA OpenCL whereas a 4550 supported it. I have had both. PrimeGrid does have CAL work. So, OpenCL is not needed. Unless I missed something anyways...

Here is a 4350 in action. http://www.primegrid.com/show_host_detail.php?hostid=418981 And as you can see it does the PPS sieve fine. It just obviously doesn't like GFN which I'm hoping to get an app_config into sometime. I don't have direct access to this PC.

A 4550 in action. http://www.primegrid.com/show_host_detail.php?hostid=431518which as well will have an app_config hopefully very soon.

What you haven't stated is if you are running any other GPU projects that might have owed run time. You don't mention what version of AMD's drivers/Catalyst you are using. The 4000 series I believe was dropped from support, so you may have to try using older versions.

You can also try running these cards at Moo! and Collatz still. I'm not sure about SETI or Einstein. I haven't attempted to run them in a while with these.

Edit: I also recommend running the latest client too. However, you can see from the two linked hosts above, various clients should work.

This computer was only just installed a few days ago, so I'll assume both Catalyst and BOINC are still the latest versions.

No other GPU projects are present, but I'll give them a shot. I still haven't found time to access the computer, so it might take another day or two.

I'll probably try the older Catalyst drivers at some point as well. The computer has an A6-6400K, so it has its own GPU built in. Before I popped the video card in, it was working with GPU units just fine. The only reason I put this old card in was because the APU was running hot, and I didn't want it getting throttled.
