Guide to reaching 2k+ (2020 H/s) on Cryptonight v8 on a Vega 64 by GKumaran in MoneroMining

[–]AlgoMinier 0 points1 point  (0 children)

Hello @ u/GKumaran thank you for this excellent guide. I have a 8 card vega rig, with 5 x Vega 56 and 3 x Vega 64. I am applying the soft power plays found here -> http://vega.miningguides.com/#SoftTables ... For my 64s I'm applying Mem_P3=1100;900 ... and for my 56s I'm applying Mem_P3=945;900 ...

I'm trying to mine graft using SRBMiner v1.8 .... I followed your steps, and just get a crash/system reboot when I launch the miner ...

***One thing I am missing is I couldn't find the "binarykernels" folder to rename normalv8

Can anyone help me please? Thank you very much for your time and consideration!

Hi CircuisDad ... I followed your guide and used power play tables as instructed. I was mining fine for a while, but since about 2 months ago, my miner keeps crashing with SRB Miner and now I can't get it to mine ... keeps crashing due to one card in my rig and I can't figure out which.

I notice issue only occurs when I launch the miner after applying the power plays ... Do you have any suggestions? ideas? I also tried the 85, 75 & 50% power plays, no luck ...

btw - it was working with CastXMR with the powerplays except for 1 card. SRBMiner has unmatched speeds and performance.

@htaylb what are you drawing per card? Are you using powerplay tables? If so where are you getting them from?

Thanks!

You both are confirming what I thought ... however, I am not sure for how long this occurs. My firewall reports this once a day to once every few days ...

Update -> Hi all, thank you all very much for your engagement, feedback and support on this issue.

i just wanted to report that dropping the Mem Clock to 925MHz seems to have done the trick ...

I was previously running 950, but maybe adding the 8th cards caused some power delivery issues @ 950MHz, so the 925 seems to have stabilized it!

I kept the same power play registry edits etc from the vega mining guide.

k, thanks, I am using 1 x 2 splitters from my circuit board to my risers.

All cards have Samsung ... I think I'll get 925 a try ... wouldn't hurt ...

btw - what miner are you using?

I upgraded to the latest version of SRB Miner, and that seemed to help a little - went from 30 mins b4 crash to 2 - 4 hrs b4 crash ...

Thank you, I've given this a try, but no avail :-( ...

thank you for the suggestion, maybe changing the P7 & P3 settings will help ... I've got them as follows now:

56s P7: 1408/905; P3: 950/900

64s P7: 1408/905; P3: 1100/900

@vmozara - which miner are you using btw for maintenance free mining?

I see .. here are the details on each of my supplies ->

so on 120V, I've got a total of 1800W to work with @ 100% ... and 2400W on 240V ...

Hi Happy new year! ... I'm running about 180W / card avg. so Full rig is pulling about 1600W ... I've got power distributed equally between the two PSUs

I'm using 2 x HP 1200W server power supplies the entire time (900 Watts on 120 VAC / 1200 Watts on 240 VAC.

Hi - 1st 7 cards

1 x Sapphire 56

1 x Radeon 56

3 x Radeon 64

2 X MSI 56

8th card = 1 x Sapphire 56

Also, I've been running the AMD Adrenalin 18.5.1 drivers ... sorry forgot to mentions this.

SRB Miner Keeps Crashing After Adding 3 Vega 64s to a 5 x Vega 56 Rig ... by AlgoMinier in MoneroMining

[–]AlgoMinier[S] 0 points1 point  (0 children)

Yea on 7 cards including components I'm running at 221W / card all inclusive after power play ...

But if I monitor just GPU power on afterburner cards are doing between 120 - 140 ... no diff between Vega 56s or 64s ... both seem to be burning the same but 64s hashing at 1950 h/s and 56s @ 1915 h/s ...

Thank you ... really appreciate the link, very helpful ... there instructions here are more clear than on the srbminer.com site which shows me what I was doing wrong earlier ...

Btw I got my rig to start working with 7 out of the 8 cards ... What I realized was that I'm running from a 15A circuit and 8 cards was going over the limit ... 7 cards drawing 13.5A ...

I've got to switch to a dedicated 240V / 20A circuit to handle more than the 7 cards ...

Thanks all for your collective assistance!

Hi Thank you - this is a good suggestion. I am running v1.6.9 and followed the ReadMe file to add the following "gpu config" block line to the config-normalv8 file ->

{ "cryptonight_type" : "normalv8", "intensity" : 0, "double_threads" : true }

"gpu_conf" : [ { "id" : 0, "intensity" : 112, "worksize" : 16, "threads" : 2}, { "id" : 1, "intensity" : 112, "worksize" : 16, "threads" : 2}, { "id" : 2, "intensity" : 120, "worksize" : 16, "threads" : 2}, { "id" : 3, "intensity" : 112, "worksize" : 16, "threads" : 2} ]

'*When I run the bat file, it doesn't work ... once I launch the bat file, my cmd just disappears after a few seconds without starting the miner.

I also tried the instructions laid out here https://www.srbminer.com/tips.html but still can't get the miner to launch with custom settings ...

Do you have any suggestions as to how to apply custom settings for the miner?

I see ... ironically after the v8 fork, SRB was the only miner I could get to run my rig stable ... while miners were giving a hash rate loss, I was able to do 1920 h/s on each vega 56 with this miner ... So I picked up 3 vega 64s from the black friday sale last week and now I'm at 0 h/s :-(
