Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[BogdanEraser]

Mr.Claymore, can we expect separate temp control for all cards in rig? Cause for example i have in one rig 270x and 290 and now 270x temp is never go more than 70, and 290 temp is still on 81. So, setting -tt 80 wil cause 270x fans to be continuously switched on and off. Thanx.

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

without these comands i have more shares in decred (( same dcri )),a little more hashrate in eth (( 2-3%-same ethi ))  0 rejects in eth and 2-2,5% in dcr .....

I decided yesterday to try dual miner version 2.0. Launched only for ETH, on RU stratum DwarfPool. Half day miner worked normally, sending the balls even slightly larger and more stable than Genoil. I decided to leave for the night, in the morning and checked to see that the floor one night were rejections. How can this problem be solved. It lacks konekt check with the server and switching to another server when the dump.

You can PM me the log with this problem, I will check it.

I will try to add it in next update.

I have 10% lower sharerate with this miner(-esm 2), than with original standalone qtminer.

anyone using Sapphire 280x vapor? im getting only like 19Mh on those aint that to low?

mine is ~20MH ETH and ~300MH DCR

1100 cclock and 1375 mclock

don't forget this on your .bat

GPU_FORCE_64BIT_PTR 0
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100

I didnt forget it, altho i was running it on stock settings that is 1070 cclock and 1550 mclock

or your 280x had elpida RAMS, read about the performance issue with that compared to 280x with hynix RAMS many months ago.

mine is hynix BTW.

that would explain it, i have elpida on them
altho i changed clocks now to 1100/1375 as You suggested and its pulling 20mh now, thanks!

read sometime ago that the hynix and elpida issue is a non-issue for ethereum mining, that would explain the 20mhs on both our cards, i think..

I used "-esm 1" and starting dualminer, it flagged it at "qtminer mode"

@Claymore, did you manage to take a look in the -cclock and -mclock flags, why they dont work? At least not on 7950 and R9 380..?

Thanks!

In current version -cclock and -mclock don't work if you did not specify "-tt" parameter. I've fixed it already, will be applied in next update. However, AMD disabled underclocking for some reason, so you can overclock only. I remember it worked in Catalyst v13.x but AMD added this stupid limitation in v14.x drivers. Right now I cannot underclock cards even via Crimson control panel, only overclock, you can check it too.

[Claymore]

I've checked ETH forks - they will be supported in next update.

[Trimegistus]

@ Claymore: do you have a timeframe for the next release? How is your work on the older/weaker cards?

Thanks, how does -tt works when it reach the set temp? Does it throttle or increasing the fans?

Glad someone else noticed this it was driving me crazy i had to flash 5 280x bios to get 1000/1250 clocks.

ok i see.... on ethermine.org it works like a champ -- 0% rejects whole day

Claymore can you please add setting for static fan speed if its not too much trouble

Ok.

Dear Claymore, can u make other dual miners aswell?
Like for example etherium + feathercoin, they are both at the top of mining currency atm for gpu.

Thanks for your work
