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?

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},

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.

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

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

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.

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?

[doktor83]

GCN 1,2,3,4,5 desktop GPU's should all work. When i say work i mean they should hash and find results.
Older cards probably don't have super speed

Wow, same here!  like 20-25w more per GPU

K, ran some numbers on WhatToMine and its actually more profitable for me to mine CryptoNight V7 on nicehash than it is to mine XMR with CNv8.  Man, I was excited for this fork because it would drop the difficulty of XMR (which it did).  I was even expecting some level sort of hashing drop, but the extra power usage is crazy...

The Difficulty isn't done dropping Let's see where we are in 72 hours.

Wow, I am impressed with this miner ....

2 Vega 56 and 2 Vega 64 (all are reference cards), from 8300 on V7 drop a little at 7800, using default config.

[-manki-]

Vega owners, check your hotspot temps. My Vega didnt survive the night mining v8 even when I dropped the core to 1250@865mV

yes, that is normal drop 100 H/s cca per Vega.

But are 56 stable or not? Please post OverdriveNtool.ini file for cards, and what soft power play table you are using if rig is stable? Temperature core of the cards when mining for couple of hours?
