Latest drivers (NVidia and ATI)

[Jason G]

Would an 'older card' (i.e. 9800 GT-series) beta bench be useful at this stage? (I don't usually upgrade drivers until the WHQL stage). If so, XP or Win7 (it'll be 32bit without the option).

Not really.  Seems to be just fairly minor gaming oriented polish for the most part (Since 285 series).  When Cuda 4.1 final release, or another release candidate appears, all bets will be off.  For now looks like they're consolidating & prepping for ~March's new GPUs, but definitely we'll want to know if 4.1 (non-RC) will perform across the full range of GPUs, when it eventuates.

Dont forget though OpenCL 1.2 is officiall pronounced.
Maybe we see another surprises with upcoming drivers.

So far as i know not fully implemented in upcoming 11.12 drivers but who knows.

I installed the 11.11c drivers earlier today to test out on a couple of games, my times doubled while crunching Millkyway. Do not recommend.

From Open CL 1.2 ... Device partitioning this is what I was waiting for ...years ...any plans for the future?
It would be great to assign just one CU to windows, and the rest to boinc . It's better than temp throttling

I finally realized that I can see the maximum power and GFLOPS from my cpu and gpu with sisoft sandra.
On my E350, without 6310M, but with a 6490M, the gpu is 6.67 more efficient than the cpu in terms of peak performance vs. power consumption.
I'm still hoping to use 1 CU with min core voltage + 1 CPU min core voltage for something around 15W, but 128 GFLOPs.
Maybe 7.0.2 with 11.12  can speed up the 1.2 adoption

[Richard Haselgrove]

The other critical piece of information we ought to derive and make available for reference somewhere is the ratio of peak to usable (effective) GFLOPS for the various computational platforms - treating hardware plus any needed runtime or driver software as an integrated platform for this purpose.

I've one ATI card HD3850 that run with OS and image software really fine, but enable to work with GPU work in BOINC, I've downloaded latest for this card from AMD 11.11 and always error just when starting with: SET, Primegrid, Collatz and Milkyway, ...

this happened again last time I'd a problem with my NVidia GPU 9800 and exchanged for a while with this one an unable to crunch with GPU, I deleted all with driver sweeper from Nvidia.

after that I bought a Nvidia GTX460 and installed in that computer and removed everything related to ATI GPU with driver sweeper and no problem at all.

some days ago I saw that the GPU card was overheated and seen that one fan was not running, it was in guaranty so to the TS for exchange, in the mean time I installed the HD 3850 sweeping again everything related to NVidia and installed AMD driver 11.11 for this card but same problem, not able to crunch.

another thing is that this computer has one HD4360 or similar on MOBO and not able to run it, doing set-up alone with another cable as HDMI or DVI, no way

11.11 drivers are incompatible with the OpenCL apps.
You can try 11.9 for example.

Did you check workgroup size of the 3850 ?
If its only 128 those apps won´t work.

If its only 128 you might want to try LHD4k version.

OpenCL is only available on HD4*** and later GPU's, HD3850 is too early, Supported Devices:

Thanks Claggy.

[Raistmer]

Also, I would check with AMD site or CLinfo utility if HD4360  OpenCL-capable or not.
Some entry level onboard AMD GPUs like 4200 and maybe 4300 are prev generation (RV6xx) cards actually and naming them HD4xxx was pure marketing move from AMD.

Has anyone tried crunching now a days with SLI connector attached and enabled? Does it work now?

Not with with my cards, My 590 got real upset with SLI enabled.

For all ATI AGP(like mine HD4670) cards driver 11.11 is available

hoping this works with ap_5.06_win_x86_SSE2_OpenCL_ATI_r521.exe

did anyone tried with AGP ?

It should work, Treasurer has an AGP HD4650, and has found a combination of drivers/SDK that work:

All tasks for computer 6052896

Unfortuently my AGP HD4650 only has an XP3200+ CPU with only SSE, (SSE2 needed) so no OpenCL support there

tried new patch no success,
ATI HD 3850 Bus width 256 / Memory size 512 MB GDDR3

BOINCTasks report:
Calculation Error (-150,)

I don't know what is the problem, but this card works in another computers and not in this since the very 1st time I assembly the computer, for the first time was working fine, after I exchanged to the Nvidia 9800 and because of one problem with this I come back to the ATI, and no way of crunching, after deleting, un-installing, etc.

later I fit the Nvidia GTX460 and no problem, now the Nvidia has one fan broken and overheat, so to Tech service and exchanged again for the ATI and no way of crunching in this computer. ??
