Hi,

I'd been running GPUGRID fine previously but after a reinstall of XP it doesn't seem to detect the CUDA drivers. I've searched around but there doesn't seem to be an obvious answer - i've tried both the 178.28 and 181.20 drivers, both after a fresh install of XP and it gives the same error each time.

Any ideas?

Did you remember to download a Cuda toolkit when rebuilding the software???

Yep, driver versions 178.28 (CUDA 2.0) & 181.20 (CUDA 2.1). I've tried both after a fresh install of XP (to rule out bad driver updates etc).

It's running 3DMark without any probs so i'm pretty sure the driver is working OK. I tried reinstalling BOINC without the protected mode on just in case it made any difference, as expected it didn't since i'm running XP.

I used NLite to make this version of windows, so I'm wondering if maybe while the install appears to work ok i've removed some component that BOINC needs. Something that allows BOINC to use the video card properly? Just thinking out loud here...

I'm running BOINC version 6.4.5 and an 8800GTS 512 (currently at stock speeds) btw, so there ought not to be a prob there.

Having the same problem. GTX 260, 6.5.0 - when BOINC starts up:

EDIT: Problem was RDP (Windows Remote Desktop) - switching to VNC fixed the problem. See my teammate Paul's thread here:

Sorry ETA I totally missed the fact you were suggesting different drivers to the ones I tried. The CUDA drivers I've used are 178.28 & 181.20 (the top two listed on http://www.nvidia.com/object/cuda_get.html).

Not sure where to get the ones you've suggested as I can't see them on the CUDA site, unless you mean none-CUDA drivers? I thought only CUDA drivers work with GPUGRID?

Ahh cheers for that, I was convinced CUDA drivers were separate to the standard ones. Bad news is I installed 181.22 and still get the 'No CUDA devices found' error.

I'm not entirely convinced the driver installed properly, just because I don't really trust Windows to run anything other than notepad without destroying itself. Are driver cleaners worth using?

It does display the correct version number in device manager at least so I might have to accept I need to make another NLite build, which inevitably means sacrificing lots more CDs till I get it right. As you say perhaps I should test with a full version of XP first to make sure i've not gone insane.

It depends how much you're into tuning XP in the first place really, and how often you reinstall windows, how many computers you manage etc. With NLite you can splipstream all your drivers, service packs, windows updates, and most commonly used programs and codec packs. You also have full control of how windows behaves once it's installed e.g. half-open connections, what services can run, basically everything you normally have to do once you've installed.

Theres an unbelieveable amount of crap bundled with windows that you'll never need, once you've cut it all out it's about 150meg (before you include your own drivers and programs) as opposed to ~600. It makes it a much cleaner, more secure install and does actually run faster in the end, on any hardware, less so on the latest rigs but still noticable.

Also since I have a dedicated 'short stroked' windows HD a smaller sized install is capable of running much faster, takes less time to defragment, and doesn't get as fragmented in the first place. This also makes it run more quickly on any PC with a dedicated windows partition.

Ok bit of a rant sorry but you did ask! In short I just don't like being patronised by Microsoft.
