PhoenixMiner 6.2c: fastest Ethereum/Ethash miner with lowest devfee (Win/Linux)

[veso760720]

Does anything happen with rx 6800
Would you mind if you set up
timings and more

[lokidiabel]

is this normal ?

If i start PhoenixMiner 5.5c on a RX 6900xt it only detects 40 CU.
I though the 6900xt has 80 CU ? Or did the miner count them different and its normal ?

<<<<main GPU1: AMD Radeon RX 6900 XT (pcie 10), OpenCL 2.0, 16 GB VRAM, 40 CUs ??>>>>

With all these fake phoenix links (note: ALWAYS follow links on original post), I wish that new users should NOT be able to post links on threads, with a setting per thread. Just make it harder for these low lives.

Hi guys, which program are you using for tweaking of rx 6800?
Thanks

I receive my rx6800 tomorrow
It would be a pleasure to share information about the configuration and other matters.
I'm going to mount it on in rig amd full:
Asus Rog Strix x570-E Gaming.
Ryzen 9 3950x 4.7GHz
Corsair iCUE H115i rgb PRO XT
Alpha AMD DDR4-3200
AsRock RX-6800 PHANTOM Gaming D OC
I already have SAM activated to test if it runs at + 80MH / s

Hi, I have alredy rx 6800 and i never reach more then 60 Mhs, what about u?
Guys can u help me someone, always if I start my Phoenix Miner then my windows system start lagging, it is really anoying, I never had this experience with previous 5700 mining...

yes there must be command -mi . you can set it lower 10 or 9. default is 12. test it. maybe you will loose some hasrate but your pc will not lag.

Really thx, I set it for -mi 2 and it get 59 Mhs without any laggs.

Hello, unfortunately I have fallen and I have downloaded the fake program that they have published, it was a Malwar. Do you know what type it is or what is the best thing I can do now?
 I have passed several antivurus and I have clean everything, apparently the pc works fine and its clean, but I am  considering formatting the computer.

I appreciate your help. Thanks

I'm sorry to hear that, but come on guys, we are tired and exhausted to say the same things again and again

DO NOT download anything except from official sources

Phoenix miner have the link on the first post of this thread

But please, format you PC as soon as you can, it's the safest thing to do

[kanzler20]

I will start mining using my Asus ROG Zephyrus S17 with the following:

Intel Core i7-10875H @2.30 GHz
32 GB RAM
NVIDIA GeForce RTX2080 Super with Max-Q Design

Can someone let me know which configurations/commands are optimal for the config file please?

And if I want to configure it so it works at a lower level so that I can still browse the web and use Excel?
Thanks!

Anyone running p104-100 with 8GB bios on hiveos with phoenixMiner? Using the -straps 4 flag the hash rate drops immediately from 36 to 30.

[mrbugera2]

how many cards? Try give 50-60gb

6 gpu in each rig.

how to increase?
 i have 16000 to 32000

i must type it in advanced settings?

1gb = 1024Mb
8Gb per card = 8192Mb vm space needed
8192Mb * 6 cards = 49125Mb vm space needed for the rig

Yes you need to enter it in the advanced settings

[hustleman]

Has anyone been successful regulating fan speeds using the command -fanmin???  I don't know if the drivers are overruning the command line but I cant get my 5700xt to maintain fan speeds.  Using 5.5c.

yes in advanced settings-custom size make minimum 60000 and max also 60000. 1st try 50000 if it is ok then use it.

You are mining eth but you written coin etc, delete coin or write eth.

[AppleMine]

Hi! The miner works great for me, thank you for all the work on it. Is there a command line option to stop it gracefully? I run it on Windows startup and therefore don’t have the console and would prefer to be able to do so instead of stopping the process. I looked but can’t find the switch / option.

Thank you very much in advance!
