The old (queer as a 3 core processor) 'puter died. Left the wife at home to invest in new Boinc hardware. Here's what I came up with...

Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz, 3401 Mhz, 4 Core(s), 8 Logical Processor(s)
Memory (RAM) 12.0 GB DDR3 1600
NVIDIA GeForce GT 640
2 Tb drive
Windows 8 (Trying to get used to that)

This thing shrubs more DDM in a day than the previous one did in a week! I didn't realize each core had two threads, so a pleasant surprise to see 8 WU's shrubbing simultaneously on a 4 core processor.

Anyway, main reason I'm posting here is this message from the Boinc client:
Quote:
No usable GPUs found

The GPU was pre-installed, so it's just a bare board with a fan, no case. Just noticed Nvidia calls this an OEM version. Need help, if I can't get Boinc to recognize it, I wasted some money as I'm not a gamer... Not to mention it would be a mortal sin to allow 384 Cuda cores to remain idle!

Thanks!

It looks like in the OEM versions, there are three varieties of the 640.

I have no idea if any of these are not able to qualify as BOINC-able, tho...

AFAIK, the entry BOINC Client for W8 is 7.0.31, Maybe you could go with higher Alpha version from here (but check on Forum(s) of projects you would like to shrub what versions are OK for their apps). What version do you have installed?

NVIDIA created the CUDA app, then they made changes to their architecture so their CUDA app become incompatible - first with Fermi (fixed now by 'the team') and then with Kepler (still unfixed here but under tests))

The new apps in test on Beta do not have this problem:
http://setiweb.ssl.berkeley.edu/beta/

They are the same optimized apps most of us (posters here) are using.
After the test on Beta is finished they (the new apps) will be used here.

Another thing comes to my mind is "Installing BOINC as services" feature. If you have checked this during installation (or if you have not unchecked this - I don't remember what is default during install - checked or not #Crazy) , BOINC client will not find a GPU. If you have so, uninstall BOINC and install it again (but definitely version 7.0.31 or later Wink )

Cheers #ni-1

OK thanks, think I'm partway there. Updated Boinc Mgr from 7.0.28 to the latest development version 7.0.52 x64. Rec'd this message:
Quote:
OpenCL: NVIDIA GPU 0: GeForce GT 640 (driver version 305.29, device version OpenCL 1.1 CUDA, 1024MB, 747MB available, 733 GFLOPS peak)

Can't tell which OEM version that is, but it is progress. BTW, I noticed during the install there is a "service install" option, which "prevents the use of GPU's". I think I used that option during the original 7.0.28 install, so that could have been the problem all along. Embarassed (Yep, cross-posted with branjo.) Will stay with the Beta version for now and see how it plays out.

Hey, I'm shrubbing a GPUGrid WU right now! Woo Hoooo! The GT640 is "most recommended" by that project.

I don't understand the info about "test apps", will look at that later and prolly post more questions.

Thanks Phred and Branjo!

Great, good luck

Edit to add: Congrats to your new rig/PC Cool

Edit to add 2: If you used to throttle CPU via BOINC Manager, since 7.0.45 the same throttling is applied to GPU.

I just noticed the client is pinging DDM every 5 seconds asking for more work. Ruh-roh, the admin Ni!co Schlitter is gonna be ticked at me! Embarassed

How is your GPU doing so far?

I have a GT 640 on one machine. It's not very good for DP. It is pretty good on the SP. It cannot do the PG GFN WR in time, but it can do it. It pretty nice on the GFN short. It did Collatz OK, but slower than I thought. It was pretty rotten on Milkyway.

Congrats on the new computer!

Hope you didn't lose anything significant when the old one passed away.

I haven't tried Win8 yet, but heard good things about Classic Shell, a project at Sourceforge.

The new GPU seems to like GPUGrid, shrubbed 650K in short order. Tried it briefly on that WCG HCC sub-project - it does crunch, but not sure how efficiently.

I'm aware of that shell and have it on a disc. Will probably try it because the Win 8 metro screen (or whatever it is) doesn't seem very useful. Have to switch from desktop to metro to launch an app, which sends it back to desktop? Sheesh...
