Definitely a "faster" miner, BUT on slow CPUs can cause mining to slow down.

All my RX480s are faster, but the biggest benefit was the 3 cards with my i7. The 6 cards with the Pentium only saw a marginal increase, 5%~

Did some testing on my 7 290x rig, with Celeron 1840. With 1.0 I was getting 360~380h/s, with 2.0 I was only getting 320h/s.

So I started disabling cards, as I disabled a card, the overall hashrate obviously went down, but the hashrate of each individual card went up. At three cards or less the cards were obtaining maximum performance, with CPU usage just over 50%. Six or less cards and I think each card was faster than with 1.0, but only just.

So 2.0 is faster if you have a rig with 6 or less cards, or you have a much more powerful chip than a Celeron 1840. Three or less cards and it should be quite a bit faster. My 290x were at times hitting over 60h/s when only three were enabled. As soon as seven are enabled i'm only getting 45h/s~

Back to 1.1 for my 290x rig with Celeron. But upgrading to 2.0 for RX480 rigs as they have faster CPUs and less cards.

Pretty high CPU usage
Athlon X2 @2.8GHz is at 60-80% usage :O

My 290s jumped 5-7 sols from 43 to 50
470s jumped 2-4sols too (hynic mem, running at 1100/1900)

high cpu usage because of cpu+gpu mining? if yes how can we disable cpu mining?

Miner works excellent for a couple hours and then crashes: Cannot seem to get it stabilized no matter what I do. Didn't have any crashing issues with silent army miner

Hey guys, just wanted to mention that -allpools is no longer needed for https://zec.suprnova.cc so you can mine without any hiccup here too, there's still 0% fee for a short period, might want to grab those coins

I lost 50 sols from 5 390 using 2.0, going back to 1.1. What kind of optimization is this?

cpu 5 to 90, extra 20w power use, about 10 extra hashes on a 6 card rx470 rig.

Cant say it true.

rig with 6 x (rx 480 xfx gtr) on v1.1 was 280, on v2.0 250-300. i would say not slower, but not so stable for 480.

So version 2 is pretty much a waste for rx series.

I am better off doing version 1. For gpus

And zcash for my CPU.

I get 26h for my i7 6700t and 135 h for my four rx cards.


But. This version seems godlike for older cards.

Leave this version as it is and rx cards will switch back to eth coin.

For now I use claymore for eth. And zcash for CPU .

This is better then claymore for Zec and zcash for CPU version 2.

Seems like Claymore put entire Silent Army code to his miner after adding MIT license notice to readme. Huge cpu usage (( My old athlon x2 cannot provide enough speed for more then 2 gpus ...

use "-allpools 1"

If you can fix the cpu ussage will be awesome

my cpu usage on rig one is 4. % 3x390x amd one 7950 total Hs 225 up from 185
rig 2 celeron 65% upfrom 8% 3x481x 8gb and one tired 7850 oc edition 155 Hs up from 143

looks like Claymore got some jokers in his sleeves. and he takes it one by one.

..2.0 Slower on RX480/70...

so the devfee is bugged

DevFee: ZEC: Stratum - connecting to 'equihash.eu.nicehash.com' <5.153.50.217> p
ort 3357
DevFee: ZEC: Authorization failed
: {"id":2,"result":false,"error":[0,"Failed",null]}
DevFee: ZEC: Job timeout, disconnect, retry in 20 sec...

Update is "now GPU+CPU mining"

Atlon II
v1.1 ~5-10% CPU
v2.0 ~48-55% CPU


v2.0
+ ~6-7% hashrate
+ ~7% from the wall

Sempron 145   100% cpu usage, and massive drop in hashrate.

PS:
my friend just fried LEPA 1000W with 5 rx cards
