cgminer mines fine on nvidia (if not the fastest)
python-pyopencl is the package you need on ubuntu

cgminer -n shows this:
[2012-02-14 13:27:59] CL Platform 0 vendor: NVIDIA Corporation
[2012-02-14 13:27:59] CL Platform 0 name: NVIDIA CUDA
[2012-02-14 13:27:59] CL Platform 0 version: OpenCL 1.1 CUDA 4.1.1

Presumably the most basic of cuda tools will work also on windows.

Has anyone else been noticing rejects due to "duplicate work"?  Never seen them before and now I get a whole bunch Huh

Just recently upgraded to cgminer 2.2.5 so maybe that has something to do with it Huh

It might be the pool but I am only seeing it on the rig running 2.2.5 (11.2 driver, 2.5 SDK)

Normally have about 0.2% reject rate on this one rig I am hitting >5% and 98 or 99 are duplicate work errors.

Interesting. It is only recently that cgminer has been reporting the reject reason. This is the same GPU each time as well, which suggests more a bug in the (new) kernel code rather than from the pool. This may be related to vectors code. What kernel is in use on this and are vectors enabled? I'm guessing poclbm+2 vectors on the GPU in question.

Further question: You're not using old kernels or kernel bins just renamed are you?

Which one is default? Smiley  I have to check.

No this is actually a clean install of OS, drivers, SDK, cgminer.

Kernel is "phatk120213.cl"

I didn't specify vectors or worksize but based bin file name I am guessing this is vector 2, work size 128

Interesting, I can't reproduce it here, but can you try starting with -k poclbm just to see if it goes away?

Tried poclbm.  Both kernels had the same high reject "duplicate work" and the rate is very high 5% to 10%.   Interestingly I noticed I had left both GPUs dynamic and 2nd thread is disabled for dymamic GPUs.  This is the first version I remember using which had this I thought it might be relevent.  I switched them both to intensity 9 and the issue has gone away ... so far.  It has gone 88 shares without a reject.  I'll run 1000 or so shares and give an update and then reboot and try dynamic again.

Hmm well dynamic could be the culprit then indeed. And that won't really have anything to do with the 2nd thread being disabled, but perhaps because the worksize is constantly changing, it might not be offsetting the right amount and repeating work. That will need fixing...

Yeah I am going to get some sleep but it is pushing 180 shares now and 0 rejects (on static intensity 9 for both GPUs).

I was noticing higher rejects with 2.2.x also, and upon searching, found this same problem with dynamic intensity. Switched to a static intensity, and the problem went away.

I recommend everyone stop using dynamic till it's fixed then.

So always use intensity 9 to avoid this bug then ?

Not quite. Always use a STATIC intensity, no matter whether it's set to 6, 8, or 14 as long as you don't use d.

DAT is using intensity 9 because he has some powerful cards. Remember that intensity is a fine-tuning parameter and higher does not necessarily mean better.
Cards pulling 230MHash/s are generally better suited with intensity 8.

Well the good news is that on static 2.2.5 has significantly lower rejects than any prior version I have used.

Yeah I am using 5870s only. I think they work best with 9 rather than 8 but I have not tested that yet.

I second that, less 1-1.5% rejects here also.  Grin

Relevant portion of .config:
Code:
"intensity" : "9",
"gpu-threads" : "1",
"gpu-engine" : "810-810",
"gpu-memclock" : "200",
"temp-cutoff" : "80",
"temp-overheat" : "77",
"temp-target" : "70",
"temp-hysteresis" : "3",
"auto-fan" : true,
"auto-gpu" : true,

This is after an hour or so of 2.2.5, but the fan speeds were the same after 70 hours of 2.2.4.

Edit:
I added:
"gpu-fan" : "0-85"
but it made no difference.  However, I watched the startup values carefully.  All three units started with fan speeds in the mid 4-thousands.  GPUs 2/3 fan speed steadily decreased but the other two units (0/1 and 4/5) remained close to where they started.  I posed my question (above) with respect to 4/5 because GPU 1 temperature is near/at the target and I thought that might be what is keeping its fan speed up, but the same can't be said of 4/5.

3x5970 -- why is my GPU 4/5 fan speed so high?

This is after an hour or so of 2.2.5, but the fan speeds were the same after 70 hours of 2.2.4.
While it's running, can you go into settings and enable debug mode and see what it's saying about temperatures and fan speeds? It will spew all sorts of info so you'll have to watch for a while to find it.
