Topic: PhoenixMiner 6.2c: fastest Ethereum/Ethash miner with lowest devfee (Win/Linux) - page 139. (Read 784965 times)

Thank you @Geniusvzla for the suggestion. I have tried that as well but unfortunately it made no difference. Are you on Windows 7?

ive find all of the phoenix miners work great from 5.1c.
i as well havent seen hash improvement or efficency.
all is good with this software. great work phoenixminer.
runing 580s and 570s and 5700xt. all 8gb

Minor note in version 5.3b, when the GPU stats print for my AMD 580 cards, they note the "cvddc" but are printing the value for the "mvddc".  When first coming up, the values are getting set correctly per the log.  It's just the periodic GPU stats print that has this mis-labeled.

Hi

Remember the "silicon lottery" even same GPU from same model and brand may have different performance on the field, I have also 3 Sapphire Pulse Rx 5600 XT. With the same settings the have almost same Mhs per second but each one have different power consumption (lower is 92W and arround 45º C, and the other 2 arround 105W and above 55ºC)

So in conclusion, not all the components have the exact same performance, and GT values is one of this specs that will vary from one to another GPU

Hi all this is my first post ever so be nice  

I have a Sapphire Nitro RX 6800 (Non XT) and I've tested with 5.4c and 5.5b and this are my results:

First Comments

Running the miner, I saw something that reached my attention, the miner reports that RX 6800 have 30 CUs, when AMD's Specs say the GPU have 60, don't know if this is something normal or is an issue.

Also I checked that no autotunning for this GPU in any Phoenixminer version.

Power consumption with this settings: 134W (In Phoenix miner)

GPU Settings

• Core min Fx: 500
• Core max Fx: 1500
• Core Voltage: 800
• VRAM Fx: 2050
• Fast Timing: Yes
• Power limit: No

With this configuration posted by Phoenixminer, the average speed reains almost the same, arround 58Mhs, but I was no able to see any peak reaching 60+Mhs however, power consumption dropped to: 124W (In Phoenix miner)

Conslusion

• The new version (5.5b) does not seems to improve mining speed
• Using second settings you can have 58Mhs at 124W, which is almost the same than a Rx5700
• If we take the price per MHs, considering the GPU cost, the RX6800 is not profitable at all, at least in my country, I can buy 3 Rx 5600 with the same money and have 120Mhs in average

Questions

• Is the fact that Phonexminer reports only 30Cus actually affecting mining speed?
• I saw videos where SAM in B550 with Ryzen 5000 is having almost 75Mhs, but miner roports double DAG for a single GPU, Is there a way to do the same for hardware out of B550 and Ryzen 5000?
• Any other setting you've tried that have better performance?

Thanks and Regards

https://bitcointalksearch.org/topic/tool-amd-compute-switcher-for-switch-automatically-to-compute-mode-2815803

I agree that's what it looks like. Is it even possible to enable compute mode on Windows 7? I was previously using the blockchain driver but started receiving more and more invalid shares until almost all were invalid. I upgraded to the latest adrenalin drivers for Windows 7 which made all shares valid again but speed is just 10.5 MH/s. I tried to add compute mode to the registry but it made no difference. So is possible to enable compute mode on Windows 7? Is anyone still successfully mining with RX580 8 GB on Windows 7?

but why does it allocate different numbers to the same GPUs with the same hardware (risers, cables, and PSU)? I know with epoch changing the gt value may change each time but for the same GPUs, it should be the same! here comes my question that which gt value is better for my cards? should they really be different that much for the same GPUs(a number from 23 to 59 is a huge range I think)?

GT value is not one way, going higher or lower from the optimum value will decrease the hash rate and may cause instability. Leave it on auto tune as recommended.

You are not in compute mode

hi. could anybody help me with this issue: Are the lower gt values for faster performance? I have 6 5700xt from the same company but each time I run phoenix miner it initializes them with different gt values from 23 to 59.iwana know which is better and faster for my cards 23 or 59? I should point out that in phoenix miner 5.1c I had experienced gt numbers from 6 to 10 but in the last version, I had the numbers 23 to 59!

Just wondering for those who are dual mining, is the miner mining both at full hash rate or do you sacrifice hash rate on both? Is it worth it to dual mine?

Also is it actually working for anyone?

Mr. PhoenixMiner
I literally copy and pasted you command line with my wallet address and it does not work.

Good Evening Everyone.

I have been using Phoenixminer for a couple of years and always read this forum for advice when stuck and could almost always find help when reading through the threads.

Thank you to Phoenix development team and forum members.

I thought I would give something back by sharing my experience.

I am currently running two mines:

1. B250 Mining expert with Intel I7 7700 and 8GB RAM for ETH
    12 GPUs; 6 x RX 580 8G, 3 x P106-100, 1 x RX 5700, 2x RX 5700XT

The RX 580`s hash between 31 - 32 MHs
The P106`s hash between 23 -24 MHs
The RX 5700 hash between 56 -57 MHs
The RX 5700 XTs hash between 58 - 59 MHs

Sample of hashrates:

Eth speed: 431.237 MH/s, shares: 110/0/0, time: 0:21
GPUs: 1: 31.745 MH/s (4) 2: 31.405 MH/s (10) 3: 23.094 MH/s (5) 4: 31.401 MH/s (12) 5: 31.671 MH/s (7) 6: 31.402 MH/s (7) 7: 23.070 MH/s (3) 8: 31.400 MH/s ( 9: 58.701 MH/s (18) 10: 56.346 MH/s (15) 11: 23.051 MH/s (7) 12: 57.953 MH/s (14)

2. H110 Bitcoin Pro with Intel Celeron 39XX and 4GC RAM for ETC
    3 GPUs: 3 x RX 470 4G
The hashrates per card is between 28 and 29 MHs

Sample of hashrates:
Will provide later, the mine is currently updating Windows 10 to feature 20H2.

Happy mining all.

Is it still possible to mine successfully with RX580 8 GB on Windows 7?

I'm not able to reach higher than 10.5 MH/s with the latest AMD driver (with compute mode enabled through registry). Older drivers gives me invalid shares. 

>> you need to put the Windows system into test mode

Did that, does not help. Even when in test mode it still asks for testmode. If I say no I get a white window. :-(

I think SimpleminingOS, HiveOS, RaveOS or similar will be easiest. I went with Ubuntu 20.04 server as I had several rigs and didn't want to pay a monthly fee. Can't really recommend it as it was a lot of work for someone (me) that's not a linux guy.

you need to put the Windows system into test mode, usually when you start this program, it is automatically prompted to do this

have you guyed tried dual mining? (there is zil coin but it is on their pool, and i want to mine eth on ethermine, and zil to its pool)

thanks for your reply

Anyone having issues with 560s? It was working fine until 5.5b. I went from 5.1c (was not playing nice with the latest Radeon driver) and now I get low single digits rates, almost as if the card was set to graphics and not compute.

I have 2 3090’s ready to cgo for this. Whats expected hash rate and roi at current eth price
