Does it support Nvidia GK104 GPU? if so, do you mind for release first version to support Nvidia ?
or let me know if you want to know the executing result on GK104 GPU, thanks.

GK104 not supported, miner works only with Maxwell GPUs (750Ti, GTX970, GTX980, Titan X).

Got this and no further question now, please keep research for Nvidia solution, hope it can be improve performance and release soon

These blocks are orphans on ypool, if you see blockchain, you find blocks mined by xpmforall.org

Hi eXtremal ,

I had some balance (more than 4 xpm), but would not become to paid.
Could you check if any wrong on xpmforall?

[funtakus]

on the calculator says 300 xpm, actually 2 times less. Why?

Hi eXtremal ,

The paid starting to increasing, bug seems to be a little slowly.

[eXtremal]

on the calculator says 300 xpm, actually 2 times less. Why?

1. Too high orphan rate (more than 10%) last 24 hours (ypool and solo mining have same problem, low difficulty and high network speed).
2. Calculator uses 30/1 10ch/11ch ratio. Now 5433/150=36.22, -20% pool luck.

I have checked payouts to other adresses, all have payouts ~calculator - 30% (some users have 170-190CPD and payouts 264-304 XPM). Now you mine 15 hours, but compare your payments with "XPM per day" value.

The paid starting to increasing, bug seems to be a little slowly.

Pool can't pay instantly with current block rate (1200 on xpmforall and 800 on ypool, normal rate is 1440 totally) can be 3-4 hours delay.

Hello. I'm using the 9.4.1 version of the miner. 8.1 Windows 64 Driver 14.12
I get 5.6 CPD to 280X (1100\1500) , config file by default. What am I doing wrong? Why such a low speed?

Use 14.4 - 14.7 drivers, 14.12 60% slower.
I will add this to first post.

[Neosaan]

14.7 driver set
280X = 7.5 CPD 
 How to get 10 CPD ?

[eXtremal]

14.7 driver set
280X = 7.5 CPD 
 How to get 10 CPD ?

If you use Windows, you can try set GPU, memory clock and powertune with MSI afterburner, or try different catalyst version (14.6, 14.4).

New version 9.4 with next speedup: https://www.dropbox.com/s/ny027u62vbeb2u5/xpmclient_v9.4.tar.gz?dl=0

Radeon R9 290X @ 1000/1250 (stock) - 14.9 CPD
  R9 290X @ 1040/1500 - 15.35CPD
Radeon R9 290 @ 947/1250 (stock) - 13.2 CPD
Radeon R9 280X @ 1000/1250 (stock) - 9.35 CPD
  R9 280X @ 1100/1500 - 10.25CPD

I have a R9 290 and have a few questions:

- Which driver will give me the best performance?

- Can I also use a CPU miner while running this program? My experience in the past is that CPU miners really cut into the performance of GPU miners. Any tips for this?

- I hear my fans turn down and then up when new work comes in. Is this normal? The Claymore miner doesn't seem to do this.

Thank you.

Catalyst 14.4 - 14.7.

You can try and post results here.

I hear my fans turn down and then up when new work comes in. Is this normal? The Claymore miner doesn't seem to do this.

Normal time for getting new work equals ping to xpmforall.org:

Code:

Work received: height=1107707 diff=10.828171 latency=39ms

But sometimes pool answers to client with some delay:

Code:

Work received: height=1107696 diff=10.828003 latency=212ms

Latency more than 1 second is enough to decrease GPU temperature and fan speed. Use manual control for fan speed (line "fanspeed" in config.txt file).

gr8 work, works out of the box for 4x 7950 and 1x 290x (with 15.5 beta driver just fine 14CPD), would be nice if mining calculator had option to include the orphan rate in last 24h so ppl would not moan on low profit btw...

miner is good it looks like it trashing the GPU at the max, power usage looks even more then with scrypt mining or somewhere there

[CoinStarX]

I used several AMD gpu's on my rigs. I only mine on new coins early on with them. I've heard a lot of good things on nvidia cards for mining too.

[Neosaan]

And have a miner for CPU Primecoin?

[Pachech]

Miner does not work

Error: -11

[eXtremal]

And have a miner for CPU Primecoin?

Yes, for other pools (ypool, etc). Difficulty too high for CPU mining now.

Miner does not work
Error: -11

I think you use Catalyst 13.x, install 14.4 drivers.
