SRBMiner Cryptonight AMD GPU Miner V1.9.3 - native algo switching

[wgestickley]

Hey Guys,

i am just setting up a new RIG and got an error i had never before...

I run 18.5.1 Driver with Windows 10 (last updated) and last SRB Version

When i start the Miner, the Wndows opens and the text says, Initialising open CL driver/cards.... but than nothing happens.... verry strange...

Any ideas?

THX

I have 6x vega 56 on v7 11500M/H with worksize8
now on v8 with worksize16, inetnsity default 0
1000M/H less.

I try to play with intensity but ....didnot manage to get back this 1000M/H.

I got about 1000 h/s on old 18.3.4 drivers. updated to 18.6.1 and everything went ok. worksize 16, intens 112 for vega56, 124 for vega64

one rig has a problem after drivers updating from 18.3.4 ( initializing opencl devices and nothing happens on 18.5.1 and 18.6.1 (

Can you post your string?

V8 more power than v7, hash drop down than v7

Hmm see the same here it use 140watt more ...

heyho, Im new to SRBMiner since today. All my Vega Rigs are running fine so far...except one

Im trying to give each card manual settings, however it doesnt seem to work -> always get parseError. These are the settings im trying to use:

"gpu_conf" :
[
   { "id" : 0, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 1, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 2, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 3, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 4, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 5, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 6, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 7, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 8, "intensity" : 120, "worksize" : 16, "threads" : 2}
]

what am I doing wrong?

Thanks in advance

Post the whole config, this part looks OK

I guess thats my whole config?
I edited the normalv8 file to the above settings. Where do I find the rest of the config? looked through every folder. The initial normalv8 config was also pretty barebones


EDIT: got it to work. forgot to set the algo^^

RX550 2G
"intensity" : 27, "worksize" : 32, "threads" : 2 = 447 h/s (510 v7)

RX560 2G
"intensity" : 27, "worksize" : 16, "threads" : 2 = 463 h/s (485 v7)

RX560 less hashrate drop than RX550

2x vega64 from about 4100H/s v7 to about 2900H/s v8 -.-"

nothing special here...

2x vega64 from about 4100H/s v7 to about 2900H/s v8 -.-"

use 18.6.1, clean cache folder and set intens 124 worksize 16. my 64s dropped only 2%!

Where i need to set intens 124 worksize 16 exaclly?

[RuMiner]

Where i need to set intens 124 worksize 16 exaclly?

in gpu config

Code:

{
"target_temperature" : 47,
"shutdown_temperature" : 85,
"restart_devices_on_startup" : false,
"reboot_script_gpu_watchdog" : "reboot.bat",
"min_rig_speed" : 16000,
"gpu_conf" :
[
{ "id" : 0, "intensity" : 124, "worksize" : 16, "threads" : 2, "persistent_memory" : false},
{ "id" : 1, "intensity" : 124, "worksize" : 16, "threads" : 2, "persistent_memory" : false},
{ "id" : 2, "intensity" : 124, "worksize" : 16, "threads" : 2, "persistent_memory" : false},
{ "id" : 3, "intensity" : 124, "worksize" : 16, "threads" : 2, "persistent_memory" : false},
{ "id" : 4, "intensity" : 124, "worksize" : 16, "threads" : 2, "persistent_memory" : false},

What miner for v9?

[BillieCrypt]

After softfork 8.0 on Monero network, this miner became one of the best for AMD cards. Unfortunately, it does not support cards of the R9 280 generation. It would be nice to add support for these old, but rather productive video cards.

[abg00]

some card crash on v8 1.6.8
use cast_xmr. low rate but stable work not crash. only rx470+

[tvukoman]

So people, V8 is here and are pain in the a..  

Vega 56 reference is max affected with change because new algo is max memory intensive and produce even more heat on poor Vega 56 reference design.

See first test of my "rig" with two Vega 56 ref, one Vega 64 Strix, and one RX570 4GB:

Power consumption for rig is 15% more, from 680W to 770W
Hasrate of the rig is down with same configuration: V7: 7170 H/s ; V8: 6870 H/s

But... temperature for Vega 56 is increased from 60 C to 67 C ;-) my Vegas 56 are throttling again and in V7 is super stable...

For now I tried to lower CC from 1442 to 1407 and in configuration of Vega 56 lower intensity from 120 / 16 / 2 to 112 / 16 / 2. Result is lower H/s for about 40 H/s for vega 56, but stability is improved for now:

GPU:4 Threads:8   H/s   CC   MC   °C   RPM Radeon RX Vega Bus:3   1938   1407   1095   63   3459 Radeon RX 580 Series Bus:6   898   1150   1980   51   1739 Radeon RX Vega Bus:11   2032   1442   1100   58   3484 Radeon RX Vega Bus:14   1936   1407   1095   66   3532

So lets all test our Vega-s, post results and we will find best solution for all...

And yes, Rx 570 4GB Nitro, drop for just 4 H/s from 902 to 898, so developers of Monero have older cards and make new algo optimized for Polaris

Do i put the gpu_conf settings in the same config-normalv8.txt ?

yes

[oxzhor]

Pfff the extra power use with v8 is killing me from 710w to 840w and lower hashes. Now i'm ending red numbers €0.19 - $0.22 per kWh.

I hope that srbminer can optimized so we get the old power use back and hashes.

After softfork 8.0 on Monero network, this miner became one of the best for AMD cards. Unfortunately, it does not support cards of the R9 280 generation. It would be nice to add support for these old, but rather productive video cards.

I thought this miner works with Tahiti cards R9 280's. I know that it supports Hawaii - 290 and 390's, so why not 280's?

Anyone still mining with the older Radeon 7970/280X or the R9 290 GPUs?

Was wondering what config you guys are using and what stability you guys get with this software, I am looking for an alternative to the Claymore XMR miner which will become obsolete when XMR forks on Oct 18th.

I tried to run the srmbminer on my 7970 with settings --cgpuintencity 15 --cgpuworksize 8 -cgputhreads 2, at the stock frequencies (925/1375) I got 360H / s on v7, its less than old claymore 11.3 (450)... but clay not support v8

PS Guys when need to change algo for Monero mining? Any dates?
