Pretty much, or at least how it was explained to me. I have even seen where people cut the cards down to fit instead of opening the slot. However, I don't recommend that since there is a lot more potential to ruin hardware.

Well, was trying and attached to a number of GPU operating grids bringing a laptop 2 the table that has 2 Graphics units, one on the CPU and one which identifies itself as an ATI HD6490M [with 1 Gig of dedicated DDR3 RAM]. Only MW has responded with the oddest rebuff:

Your NVIDIA GPU lacks the needed compute capability (1.3, needed for double precision math.

Is it seeing the CPU based graphics module as NVIDIA or the ATI card? The device manager says there's a Intel HD and a Radeon HD6490M.

Anyway, anyone knows a project or projects that can do [light] crunching on the ATI? TThrottle recognizes the card and is able to throttle it, so it would be running likely on half power, not to fry things.

MOO! has the least amount of requirements and will get you more points then PrimeGrid (which favors nVidia cards) or Collatz which favors ATI/AMD. But all three "should" work. I know nVidia cards only need 64MB for Moo! but am not sure if they ever lowered ATI/AMD requirements down from 256MB or not.

Edit: Totally forgot, but you could also see if it will run on POEM or not. I think as long as it is above like a 4500 or maybe 4600 series card. You will need to run 7.0.3 or newer with updated Catalyst drivers.

Edit 2: I have read some using the version 12 drivers for Catalyst which aren't official yet getting much better efficiency from their cards. However, I haven't tested any of it myself.

Albert@Home is also developing OpenCL for ATI/AMD.


* AMD GPU (500 MB free GPU memory, OpenCL 1.0 support)
* AMD Catalyst 11.7 (8.872) driver (and newer)
* BOINC 7.0.1 (and newer)
* Windows, Linux or Mac OS (10.7 only)

No specs or message details, so guessing that might be a Mac with Intel’s on-die GPU and an HD 6490M?
Heard of someone recently crunching using an on-die HD, but never an on-die Intel GPU. It’s still a waste of die space - well almost; if you can use it for your display and crunch on the real GPU it’s of some benefit.
While the HD 6490M should work at POEM on Win/Linux, there is no POEM++ OpenCL app for the Mac!
I think the MW rejection message is just a generic for not being double precision enabled (driver/GPU dependent); Compute Capable 1.3 or better NVidia GPU’s are double precision, anything less is either not up to the task (crunching at MW) or is not double precision. I think the message was aimed at the HD, rather than the Intel GPU, as the 6490M is single precision only. While Intel on-die GPU’s could in theory be used for some parts of some code they are not OpenCL friendly.
The HD 6490 is OpenCL capable, so as suggested above, use a recent Catalyst driver suite, and for now stick to 7.03 if you want to try POEM. There are a couple of heavy threads there. The app tends to only be ~50% optimized for the GPU (not enough loaded into GPU...), so should work without throttling. Tuning/downclocking would probably be a better option anyway. Most people are using app_info files to get performance %-ages up to the high 80's. Anyway, worth a look if your not on a Mac.
