Anyone setup for 580 8gb Sapphire Nitro Hynix memory Monero algo

One click Bios mod with srbpolaris bios editor

Sapphire Nitro+ 580 - 8gb
925 H/s [1250 core / 2250 memory] Intensity: 58 Worksize: 8 Threads: 2

Try this setup with that bios 6x580 1180/2150 900mv/950mv 942 per card 780w
{
"cryptonight_type" : "normalv8",
"intensity" : 100,
"double_threads" : true,
"worksize" : 8,
"threads" : 2,
"fragments" : 16,
"bralock" : 50
}

If anybody have better setup pls give us 

Ill try this also and report back, It's just weird how the 4gb cards hash at 1015+ and the 8gb are between 925-975

is SRB 1.6.9 working on win 10 LTSC version? I got hangs after 1 min of miner work...

Hi, I have some questions some of you may be able to answer for me..  (using Strix Vega56s non flashed latest drivers) /w SRB miner.  

I was reading thru setting everything up that's all good. Works well but decided to also try out OverdriveNTool (latest version) based on some of the posts I've seen..

Questions:
My first 5 Power states appear to reset I apply them P6/7 get applied.  Is this normal? If not how do I correct that? (I've tried refresh/reload)

Also wondering if these settings take after a restart of the computer, They don't appear to.. at least not fully.


So far my workaround has been to start the computer.. Run Overdrive tool Loading a saved setting. Then use afterburner to manually set some things. Getting 1740H Per card (have 2 cards mining xmr) /w temps 52/55C Powerdraw 470W roughly total system (ryzen cpu mining to) So apparently it's sort of working... but i do have to rerun Overdrive everytime I reboot.. and I do have to use afterburner to adjust.

(Note before using overdrivetool I'd simply undervolt with afterburner by -131  set pl to 70%  Core to 1400 mem to 880 but temps would be 60/69c for the cards and about 150w more system power)

4GB and 8GB dont hash the same. on Monero 8gb is slower on CNheavy is where the 8gb shines like 1100hs+

4GB and 8GB dont hash the same. on Monero 8gb is slower on CNheavy is where the 8gb shines like 1100hs+

not exactly, on 8GB sometimes intensity 64 works better then 58 or 71.

What is the best way to disable GPU in conf?
i.e -di in Claymore

[doktor83]

What is the best way to disable GPU in conf?
i.e -di in Claymore

for example if you want to use gpu 0,2,4,5 :

Code:

"gpu_conf" : 
[ 
   { "id" : 0, "intensity" : 50, "worksize" : 8, "threads" : 2},
   { "id" : 2, "intensity" : 45, "worksize" : 8, "threads" : 2},
   { "id" : 4, "intensity" : 40, "worksize" : 8, "threads" : 2},
   { "id" : 5, "intensity" : 55, "worksize" : 8, "threads" : 2}

Hi.
Please, help me to understand the values of intensity parameter... (I'am trying to get maximum hashrate without HW errors)
In other miners it's calculated from the number of shaders, but there is a results such as 768, 896, etc.. In SRBMiner there is some values between 1-300. How they are correlated with the standart values? For example, intensity of 58 = ??
And what formula I should use for calculations, if I know mem size and number of shaders?

Maybe, someone can share their "intensity" and "worksize" settings for RX560, RX570/580? (interested in normal and heavy/haven algos)

Also, is there any way to get per-card statistics in SRBMiner? Accepted, rejected, HW errors...

Will be gratefull for help.

Looking at profitability charts something seems wrong, I went on whatomine and it suggested to switch back to ethereum , due to the power/hash combination of cnv8 vs ethhash.

Something is really off becase when i moved my rigs to ethereum from cnv8 my power use went up by 4 amps

that basically an extra amp per rig nearly.  that is around 1000 watts at 240V.

someone needs to correct the power use calculation used by the profit calcs . V8 uses more power than v7 but no where near close to ether as the calcs have it

Well, I just reinstalled Windows. Fresh latest drivers, disabled CF, applied OD settings,... It didn't help. It was running at full for a bit, then the second card dropped to about 1100h/s. I don't know what to do anymore.

Hello,
I need some help,
I have 4 RX 580 nitro + (8go) , 1 hynix , 3 micron . I was mining with SRB at 850h/s each (V8 Xmr)

I did this to increase my hashrate.
- Custom build with SRB Polaris ( I just pressed PIMP my strap then save BIOS and flash)
- then I DDU my old driver and install new one 18.6.1.
- then used atidmkpacher
- I tried the latest version of the miner with 58 intensity double thread for each RX580.

But now I'm mining at 350h/s each...

yeah I forgot that  thanks ! but even now I'm around 850h/s no more 

[Bojcha]

Hynix 8GB is crap for CN. You need better strap (if there is one)

[carlosmonaco]

I have only one with hynix others are micron but hashrate remain the same 850/s.
Someone can share a BIOS for RX 580 nitro+ ( 8 go) hynix and micron ?

V1.7.0
- Speed increase on BitTube/Haven/Heavy/Italo algos up to ~10% (depends of gpu)
- Small speed increase on V8 algo for Vegas
- Added new algo CN-Dark [CryoNote]
- Added new algo CN-Fest [Festival coin]
- Added startup monitor which monitors miner startup process
- Added new work mode for GPU hashrate watchdog [--gpuwatchdogdisablemode]
- Added yet another gpu tuning parameter 'aes'
- Fixed a bug related to hash speed monitor and algo switching
- Small bug fixes


+ Performance boost for BitTube/Haven/Heavy/Italo algos up to ~10%, some cards gained 1% some 10%, i don't have exact numbers, you should try it out and see.
Vegas gained the most, also i hope that i fixed the Ellesmere 8Gb cards problem, not reaching max hashing speed. If you had 1k+ on some earlier versions, you should be able to reach it now again but you MUST set fragments to 0 if you are setting it by hand, otherwise it probably won't reach max speeds.
And no fee increase because of the extra performance, it stays at ~0.85%

+ Some small optimisation gained around +10hs on my test Vega56 on V8 algo

+ Added new algos : Cryptonight Dark and Fest

+ Startup monitor, a few of you have problems that sometimes miner wont hang, but it stops on GPU init process. I added a watchdog that should restart miner or run a user defined script if miner won't start working for a period of time. User can define this time period, default is 2 minutes.
So if miner can't init gpu's but the process did not freeze, or hang, the watchdog should trigger after 2 minutes and restart the miner.

Parameters that can be set in start.bat :

--maxstartuptime value (max time to init gpu's and start mining, min 10 sec, max 10 min, def. 2 min)
--maxstartuptimescript filename (run this script if maxstartuptime is exceeded)
--disablestartupmonitor (disable watchdog for miner startup interval)

+ If you dont want the gpu hashrate watchdog to restart the whole miner if a gpu hangs, now a new mode is available : disable mode
What this does is if it detects that your card can't hash (speed is 0), and its not because your driver crashed (because if that happens nothing can help you   ), then it will disable that gpu, so the other gpu's can continue to work and no miner restart will occur.

To use this mode put --gpuwatchdogdisablemode in start.bat

+ gpu_conf, new parameter 'aes' . Never enough of extra tuning parameters, right ?
This parameter can have the value of 0,1 or 2. Default is 0, and it is probably the best option for newer cards. This parameter just select the method for AES calculation part in the kernel. You can try it out, maybe you gain a few more hashes if you find the right one for your GPU
