where can I find new version? 1 post isnt that the old one?

[teenagecheese]

Reporting maybe .4 hpm increase with new miner on R9 290. Thanks for putting these out.

Edit: ...and getting coil whine now too. Is that bad for the GPU, should I switch back to the old miner?

[phrozenspite]

trying it now.  i might be seeing about a .5 hpm increase on my 7970, but i think desktop interactivity while mining has increased lol

Guys,

We have finally updated the miner. It has a slightly better HPM than previous version and tries to run on Nvidia.

Please report your success (or lack of) running it.

[Drew]

Awesome!  Can't wait to try new miner.  I have an Nvidia 680 I can see if it is worth mining on.  Will the new miner work on a 6990 with 2gb of memory?  All I get are rejects, but it thinks it is supported currently.  Thanks for all your efforts on this!

What might be the cause of increasing rates of rejects, it usually gets worse later, like this:

Either they are stales, or the card gives hardware errors. New version of miner will print reject reason for rejected shares.

I'm down to beta test a GPU miner for HD 6970 2GB.

Currently the miner produces only rejected shares with a 5xxx / 6xxx card.
If reorder will be kind enough to develop a fix for the current miner it will be great!
A lot of us will not only beta test it but actively use it!!! 

(meanwile I am waiting for my 7970s to arrive...)

[phrozenspite]

awesome keep up the good work

[TiGei99]

A slightly optimized (~5%) and supporting Nvidia (maybe, tested only on AWS) miner version is on its way. ETA is several hours to a day. I will post an update when it is ready for download.

Nice news

Guys,

I have now a build of GPU miner that works with Nvidia. Its performance is rather disappointing, though: AWS g2.2xlarge (GRID K520) yields just 3.58hpm. It cannot be significantly improved upon. Consumer-grade cards would yield a similar or worse performace. Given that, please give your opinion on whether you would be using such a miner.

I'd love to do a tester

Do you use CUDA or OpenCL?

OpenCL for the moment. It is calculation-bound though, CUDA would not make much difference.

someone please explain me why are a huge different in performance between 7950 and 7970??
with my 7950 got 10 hpm >>> scrypt mining 650
with my 7970 got 19 hpm >>> scrypt mining 600

why is so bad the performance of the 7950??
Thanks

the 7970 should be faster in scrypt as well.  7970 is just more powerful in about every way

7870 gets almost 10 and my 7950 gets the same.. do you think the 2 gpu are the same?

The 7870 that does 10hpm is gigaherz edition, 7950 runs cores at 800MHz. This compensates for the difference in number of shaders.

my 7950 is oced to 1050 / 1400.. i think there is a bug or anything with 7950..
