I Also noticed that the last RX550 never goes above 470h/s for some reason
The same was noticed in 31f build i an before

Hi guys. Has anyone tried Masari on RX550 / 2 GB. I can not adjust parameters either as stable. on the buffin, the cards give out a maximum of 950 h/s for a short time and then the system drops, and 4 cards on the Lexa give out only 800 h/s and  then the system drops.

Here is what i used, don't remember exact numbers but hash was around 900 h/s from RX550 2G Hynix

Code:
{ "mode" : "GPU", "worksize" : 8, "alpha" : 128, "beta" : 16, "gamma" : 8, "delta" : 8, "epsilon" : 8, "zeta" : 8, "index" : 0, "multi_hash":432 },

Hi, how old is the M900? Can you post some pics of it to see the condition please. (Inside as well)

Thanks!

M900 was bought last year by a company i used to work at, but was hardly used, just sitting in storage. I bought it from them last fall with the intention of building a firewall appliance with it but opted out for VM ware based server. I'll take some pictures today and will update the post

Anyone has some good settings mining Cryptonight-Fast? Thats the latest Masari Algo. So it looks like the regular V7 settings work pretty good.

Could you show me how are you running? im still having problems to connect to my proxy.

all i did just added --nicehash  to the command line

JCE explicitly forbids use of any proxy, i tell it in the doc. that's a security feature, otherwise a miner+proxy packed together could be turned into a botnet with ease.

Jyst FYI, im running one of my miners with JCE through xmrig-proxy with no issues, all i had to do is add --nicehash to the start command line.
33  Alternate cryptocurrencies / Mining (Altcoins) / Re: [XMR] JCE Miner Cryptonight/forks, now with GPU! on: June 28, 2018, 08:34:34 PM
i don't know why, i just bought two rx550, same speed and half the price, and consumes less power.

ho, and to answer a previous question: gpu and cpu combined. i think it's good because it allows a cpu to participate to big share mining without being kicked. sure it will find one share per hour but it will worth a lot. i like to see my core2 find a 120000-value share, in the middle of my gpus Smiley

I agree, 550s are great but only when you have space to put 12GPU rigs and a lot of them.
In my case, its all about the density, but VEGAs are too expensive so i rely on 570/580s

However i could invest into a Vega if JCE GPU is successful, even if my favorite GPU is RX550 (1/4 speed of vega for 1/8 of price)

Can i suggest also invest into rx570/580, i think the majority of people (myself included) have those cards and would really appreciate any further optimizations
I really like the miner, running it already for 2 days on both rigs. Keep up the good work!

Ohhh. For my RX 580 8Gb finded new best intensity for heavy algo:

Code:
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "gamma" : 4, "delta" : 4, "epsilon" : 4, "zeta" : 4, "index" : 1, "multi_hash":832 },
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "gamma" : 4, "delta" : 4, "epsilon" : 4, "zeta" : 4, "index" : 1, "multi_hash":832 },

Also finded good parameters for cn-v7 algo for 8Gb cards:

Code:
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "gamma" : 4, "delta" : 4, "epsilon" : 4, "zeta" : 4, "index" : 1, "multi_hash":1696 },
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "gamma" : 4, "delta" : 4, "epsilon" : 4, "zeta" : 4, "index" : 1, "multi_hash":1696 },

Also miner often gives rejected shares "Job not found"...

Just to add more data, for RX570/580 4GB cards, the best settings so far for me on cn-V7 are:

Code:
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "gamma" : 4, "delta" : 4, "epsilon" : 4, "zeta" : 4, "index" : 1, "multi_hash": 944},
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "gamma" : 4, "delta" : 4, "epsilon" : 4, "zeta" : 4, "index" : 1, "multi_hash": 944},

is there a better config for a RX580 8GB? With cast xmr i can get pretty much stable 1kH/s.

"gpu_threads_conf" :
[
     { "mode" : "GPU", "worksize" : 8, "alpha" : 128, "beta" : 16, "gamma" : 8, "delta" : 8, "epsilon" : 8, "zeta" : 8, "index" : 1, "multi_hash":944 },
     { "mode" : "GPU", "worksize" : 8, "alpha" : 128, "beta" : 16, "gamma" : 8, "delta" : 8, "epsilon" : 8, "zeta" : 8, "index" : 1, "multi_hash":944 },
]


EDIT: Algo is cryptonight heavy. Also the hashrate with JCE is much more stable. nice work!

For RX580 8GB the best settings i found to be below:

Code:
{ "mode" : "GPU", "worksize" : 8, "alpha" : 128, "beta" : 16, "gamma" : 8, "delta" : 8, "epsilon" : 8, "zeta" : 8, "index" : 0, "multi_hash":1200 },
{ "mode" : "GPU", "worksize" : 8, "alpha" : 128, "beta" : 16, "gamma" : 8, "delta" : 8, "epsilon" : 8, "zeta" : 8, "index" : 0, "multi_hash":1200 },

XMR-Stak is not fastest cryptonight miner. You must try SRB miner. It faster XMR-Stak or XMRig.

I tried them all my friend, SRB for me does give a higher hashrate displayed on the rig, but on the pool the hashrate is lower, also SRB is higher about 1-3 % so not worth the hassle considering the fee
You just didn't know optimal settings for SRB miner for your cards. It's faster significunt. Expeccially on heavy. On normal v7 srb 1.6.0 can give max speed with the right .srb kernel file. For heavy 1.6.1 can give max speed with the right kernel.
On the pools side all right. I checked SRB on few pools, all right. Many forgot that often pool take fee.


Can you share you SRB config/kernel for V7 on RX570/580 4/8GB?
I would love to try it out
Ok. I didn't have 4Gb 570/580 card. There is .srb kernel bin file for rx 580 8Gb: https://yadi.sk/d/1QFcuG-g3YVNWg
This file needs to be copied to "cache" subfolder of SRB miner folder.
Than you need 1.6.0 version of miner. On 1.6.1 speed on v7 is lower.
In config:

        { "id" : 0, "intensity" : 116.0, "worksize" : 8, "threads" : 2, "persistent_memory" : false},

It's for 580 8Gb card without connected monitor (more available video memory). Maked and tested on Windows 10 x64 1803 with AMD 18.6.1 driver.
This settings require about 7.2Gb of free video memory.

P.S. Kernel bin from link woudn't work on 1.6.1 version. doctor changed cn kernels on 1.6.1 version...

Thanks for the link, just tried and in fact its a better kernel for RX580 8GB.
Where did you get it, is it possible to get one for 4GB RX570/580, i only have 2 8GB cards Sad
