Primecoin GPU miner: 9.1 CPD on a 280x / pool / 2% dev.fee

[Stratobitz]

Interesting enough, I seem to be getting 16.7 CPD with 4x 280x cards / 4770k CPU.

Been running 16 hours and I've gotten 2 blocks.

This was with some fiddling with how the miner is set up, and tweaking the settings on the GPU.

Going to see if it holds up and keeps going at these rates.

I have gotten 8 blocks since I switched to ver. 2.00.

Any orphans?

wtf 16 cpd.

i have same setup but with fx-4350 instead, only got 7.5 cpd.

Must be schewed...

How do you use the free version? Only one exe?

Khm... doesn't seem right.
Please post you 'time' values. Also, could you please try different -cpuusage values.

[bclcjunkie]

You just got lucky due to ypool going offline for several hours.. I hit 3 during that time..

I am getting 8.5 cpd average with 3 x 290x.
I am getting 5.8 cpd average with 7970,7950,7950,270 - this is with the 280x client. It seems to produce the best results with the mixed GPUs.  I have gotten 8 blocks since I switched to ver. 2.00.

I am pleased with the improvements.  Good work primegpu.

you found blocks with 290s or other cards?

blocks were found on both machines.  now 5 on 290x's and 4 on mixed gpu rig.

Yep, it's combined in one exe.

Time values are 95 to 106 fluctuating a bit. It clicks through the passes a little faster than 1 second per pass, l like a slightly faster stopwatch.

Again this is with some mods I figured out to the miner in combination with finding by trial, error, and a bit of luck- a sweet spot for GPU settings. ,I'm using 2.01 paid version. CPU usage value set to 11.

Just restarted miner with another tweak. Going to let in run overnight. Here's pic:

my wallet must be closed to run the program right?Does it connect to my wallet.dat auto?And overclocking the cards helps finding blocks faster or not?

Yes, and yes.

Cpu overclock doesn't make much difference...only gpu and system ram clocks/timings make any difference for me.

So please make a pool version! It's realy importent with current difficulty!

If you have 4+ cards it's actually better to mine solo.
Those currently mining on ypool with 280x's are giving up at least 3% + 25%.

That being said, we're working on a pool version.

Yep, I have 6 r9 280x, also have a problem, you update your miner to work with catalist 14.3+ but I can't find modificated drivers to run all of my cards (for catalist 13.12 this problem solved https://litecointalk.org/index.php?topic=11761.0).
Win8.1x64 in "CCC -> Information -> hardware"  see 1 card Primary 4 cards Enabled and 1 card Linked. I can see only 5 of them in the windows display settings and in the miner (think - linked not work).
In the device manager all of my cards showed without issues.
May be somebody solves that issue?

i am confused:i was using 950-960 watts from the wall (3x290)with claymore v 4.0 total cpd was around 7.5-7.7and usually  i was finding 2 blocks per day untill today.With this i am using 820-830 watts from the wall cpd is 8.74.Will this be faster?

What settings are getting you those times?

With the 14.3 driver, is it possible to have 6 GPUs?

[bclcjunkie]

of course why not...  mine is latest cat 14.4 running 4x7990 rig and that's 8 gpus...

Maybe I need to be clearer. Is it possible to have 6 cards?
On the 13.12 drivers you needed modded drivers for win 7 to even accept all cards.
