I uploaded v2.1 to my MEGA folder, see original post for the link.

What's new:

1. Added "-hc" option to improve stability for some cards/systems.
2. Added "-ss 2" option to reduce CPU usage even more.
3. Changed GUI: now with "s" key you can select minimal/detailed statistics.
4. Added estimated and average CPD (chains per day) values.

Tested on my rigs,270 should set hc to 300 or 320,TRT is better than 256, driver crashed over 350.

Something interesting happened during the process of testing.

-ss 0 working?
when i use -ss 0 - GPU load is 60% only - not 100%....

... -p x -di 2 -hc 512 -ss 2 -sd
makes miner crash, removing -sd makes it work again.

You should specify "-sd 1" or "-sd 0", not just "-sd". Same for other parameters.

Your CPU is too slow to handle 6 cards, you should get about 120K 4ch/h for 280X. In future versions I will decrease CPU usage.

Core number is important? I want to try AMD FX-4XXX or AMD FX-6XXX

Number of cores must be >1 for good results. Anyway, I just found how to reduce CPU usage again, so I will add "-ss 2" option back in v2.1, I will release it in a couple of hours.
I see about 50% less CPU usage with this option so you can mine on x6 cards even with slow CPU at full speed.

I do have amd FX-8350 if thats interesting to test...

hardware: 4x r9 280x with an Athlon II x2 240e(2 cores)
With -ss 2 my 4ch increased from 103k to 120k, while cpu usage drop from 83% to 50%, nice!

cpu usage with -ss 2 now lowered to 40% on my 5x280x rigs with pentium haswell(about 7% per instance), and gpu usage up to 95%+-. great work

Damn .. issit GPU mining supposed to alleviate CPU load?

I ran for a few hours, came back and noticed no shares being found, unlike how they were at the beginning.

Checked the Afterburner graph and see that the GPU temp dropped down to 32 -- i.e. GPU stopped being used.

Question: if the driver crashes and relaunches does that completely kill the mining? B/c if so, the miner is pretty useless for unattended mining.

This system is 64 bit Windows 8.1 with the 13.12 driver but still, perhaps because the clock is too high, but it seems like the driver crashes sometimes and restarts. The mining process needs to detect if there is something critical not working and relaunch if necessary otherwise it just doesn't work, right?

Anyone else have a similar problem? I'd love to be able to leave the mining going at least 8 hours while sleeping and feel confident it's going to keep mining.

fullspeed? -ss2 won't hurt the gpu bandwidth even a bit?

sounds awsome.

It decreases mining speed by 3-4% only.

My results
windows 8.1 x64, cat 13.12,claymore 2.0
6x280x GPU/MEM 1030/1500, Load 72-90% (avg 85%), Temp <55C
CPU Althone II X2 250, CPU load 94-100% (avg 96%)
3 x instant run default setting (-ss 1)
3 x instant run -ss 2
miner speed:
102K 4ch/d stable for all instant
67-72 7ch/d depend on GPU

"-ss 2" - there is no such option in v2.0, check latest readme, it works same as "-ss 1".

Maybe problem is that CPU is A4-6300 APU?

I don't think so, though cannot be sure. In a few hours I'll release v2.1 with "-hc" option, then try to set "-hc 256" or "-hc 128", perhaps it will help. Also try "AMD Clean utility" to remove Catalyst completely, then install 13.12.

Have problem with 7870 rig - any time i start miner i have drivers crash. tried to lower threads - same result

1. Install Catalyst v13.12.
2. Disable overclocking.
3. Reboot computer.

1. 13.12 is there from very beginning
2. tried even downclocking - same result
3. many times

Maybe problem is that CPU is A4-6300 APU?

Sorry if this seems lazy but has anyone already compared exchange potential using 1x 280X card crunching Claymore XPM's vs. something like Clevermining?

Clevermining currently claims about 0.00499 BTC/day per MH/s.

If one were not attempting to mine and hold XPM any idea what a 30-day average of auto-selling XPM would bring per MH/s?

I believe some has done the math, and it was something like 90% or more, compared to scrypt if i remember corect.
Dont take it to the bank tho, xpm is alot of luck if you mine it very shortly!
Happy mining
