Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[Za1n]

Added another 5% or so on all my rigs with older cards using the -i 2 switch.

On my Rigs with newer cards, such as the RX series, I actually seen a slight decrease versus version 2.0. I have tried all three intensity levels and even the -i 2 gives a bit less sols and the CPU usage is greater than in version 2.0. I am still playing around as it might have been my lowered clocks, but it seems this version was geared more toward the older cards.

I get about 2-3H/s boost on all my 470s and 480s, 4GB and 8GB versions, most sapphire some others. Just have dual cores, mostly celerons, one APU.  You can try setting ZecMiner priority to above normal in task manager, it may help slightly.  Also check if other processes are using much CPU. Surely there is more room for improvement on Polaris, but I got boost from 1.1 -> 2.0 -> 2.1

Thanks for the suggestion. I might play around a bit more, but according to Claymore's last post this version was mainly for the older cards anyway. I don't run anything but the miner and VNC on the rigs once I get them dialed in, so I doubt setting the task priority higher will help much, but I will test it out anyway.

Claymore, maybe u can change the color of the "dev fee shares" from green to blue or something. So people stop asking. Hehe.

I'll think about it, may be it's a good idea. The problem is that as soon as "devfee: connect to..." string is appeared, some people think that devfee mining is started. I don't want to hide any devfee messages, but this misunderstanding is annoying. So may be new color for devfee time is a good idea.

How about yellow to make it really stand out from the rest of the text?

Claymore, is this ok that CPU overloaded again in v2.1 with "-i 1 or 2"?  CPU exactly, not GPU.
And as result higher hashrate at 390x with "-i 0", but not with 1 or 2.

[arielbit]

one of my 280x rig won't start mining with "-i 2", just 0 h/s and on and on .. "-i 0" and "-i 1" works

I would leave "Devfee connect..." the same, change color of "Devfee share found", so it is obvious to those who don't read FAQ when it is actually dev mining, and when it is trying to connect.

I'm getting an extra 5% or so going from 2.0 to 2.1 and using -i 2 on Hawaii cards. CPU usage is only slightly higher and still only seeing partial consistent load across 3 cores on a 3.7GHz Thuban. Uses about 6GB of swapfile instead of 3GB on v2.0.

v2.0 (Rock-solid stable for over 19hrs)


v2.1

How would you know? You only wrote the program

[felixbrucker]

my 7970 went to 47 Sol/s and my 290x to 57 Sol/s, thats some nice improvement (-i 2 used), thanks

r9 270 2g with 1200/1500 -i 2 seem to be fine for me
edit: 270x sorry

It's not so difficult to check - download WireShark and check the data traffic from miner. Logfile from miner + Wireshark to confirm data and time.

In "-i 2" mode miner uses almost 2GB, so some 2GB GPUs may fail.

Heheh I was kidding. But good info for any tinfoil hat guys!

I think some may have the full suit, not just the hat

just for clarity for how long does dev fee mine

When you are at it please change the color of the temp/fan output line as well. Dark purple on black background in the terminal is impossible to read.
