Is it possible to use a GTX 460 still?

Have you 'allowed' the FGRPB1G search?  Have you set your preferences to allow your GPU to be used?  Do you have the necessary OpenCL components installed?  During startup, does BOINC properly detect your GPU?  Can you see this in the startup messages?

If the answers are 'yes' to all of this and you are still not getting any work, perhaps you don't have enough VRAM.  I'm not sure what the actual limit is these days but it may well be 1GB.

Please realise that even if you get it going, crunching is likely to be very slow and inefficient - high power use for low crunching output.  An upgrade to a relatively cheap but more modern and more power efficient GPU can be a very worthwhile exercise.

 

The GTX-465 worked soon after I accepted CPU work.  Perhaps it needed CPU accepted since it uses one core per GPU task.  Haven't received any GPU for the GTX-460.  There may be a memory limit.

The GTX-465 had no problems and completed the tasks in 2 hours.

You didn't mention a 465 in your previous post - just a 460.  You don't need to accept CPU work in order to get GPU work.  The two searches (FGRPB1G and FGRP5) are separate and don't interact with each other in any way.

I just had a look at your computers list and I see you have two machines.  The one with the 465 shows as having 961MB VRAM whilst the one with the 460 has a 'too low for sure' figure of 709MB.  That will be the reason why the 460 is not being given GPU work.  As a result of allowing CPU work, I see your machine with the 460 actually got a CPU task.  I guess you have stopped CPU work for that machine as it only received the single task.

 

Cheers,
Gary.

Thanks for the info Gary.  I guess the GTX-460 is about ready to retire.  There are a few places I can still use it, though.
