So always use intensity 9 to avoid this bug then ?

Thanks !
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.

Now you mention it, I'm having the same issue with dynamic.  I just wasn't sure what was causing it Smiley

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...
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.

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).

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
"phatk120213Cypressbitalignv2w128long4.bin"
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.

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.

Which one is default? Smiley  I have to check.

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

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

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.

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.

Think for yourself
If you know of a more appropriate CUDA miner, I'd love to hear about it!
rpcminer-cuda is the only CUDA miner, I think.
But rpcminer doesn't support longpolling or any other advanced features.
OpenCL miners are a little bit slower.
cgminer does it - but it seems no one who uses it knows what is required to install to get it working Tongue

Does it or Did it?  I see no references anymore to NVidia or CUDA on the top post.

I have a question regarding the SDKs..

For HD5xxx users the SDK 2.1 is the fastest and I would like to use it.
Does it already contain all the functions we need for CGMINER, supporting GPUClock, Memory and Fan settings?
Is this related to SDK or driver version?
Driver has those functions. 11.6 or greater driver. SDK 2.1 should be fine.
