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

[relax69]

Hello, I have 3 x MSI rx6600s (non-xt) cards which are behaving strangely when I use the -cvddc command. Running under windows 10.

One of the cards will happily change voltage via phoenixminer using e.g. -cvddc 750 or -cvddc 800 or whatever. Works fine using 750, pulls about 55w which is ok.

The other 2 cards automatically crash the driver (and the card won't generate a DAG) whenever I try to set core voltage via commandline for some reason - regardless of what voltage I set. Even if it's -cvddc 800 or 900 or 1000 or 1100 or whatever (more than it should need), the 2 cards won't change voltage via phoenixminer.

Both these cards WORK FINE when you don't set voltage via phoenixminer, and you can change their voltage via the radeon software no problems.
The cards behave the same regardless of which PCI slot they're in, or whether or not they use a riser.
Same behaviour in phoenixminer 5.8b or 5.8c.
Same behaviour using either AMD drivers that support 6600 non-xt cards (21.10.2 or 21.10.3)

Does anyone have any suggestions for this issue? (other than "install linux"). Is this an issue with the driver, miner, or cards? (although if this was happening on one card I would think perhaps it's the card, but 2 out of 3 seems unlikely).

Thanks in advance for any assistance.

Because it is happening during the DAG generation, it sounds to me is crashing because of too much overclock of the memory. I would try to lower OC on the memory or leave it to default and see what will happen. Also, try to change core frequency and voltages. Not all cards of the same brand and the same model will work with the same overclocking settings.

Also, will be good to post the log file, so someone with more knowledge could read the error code from it.

Finally, these cards are still new, and you have the option to file RMA for replacement.

If you only use one of the two cards without others, will it work? And when you use PM to specify -cvddv, do you specify one value or three values such as -cvddc 800,800,800? Note that space is not allows between the numbers. It causes PM to crash when I tried it with 5700XT.

Thanks for your reply.

The card that works fine will work fine by itself or when in a rig with other cards.
The cards that don't work as expected behave the same if they're in a rig by themselves or with other cards.
The same cards fail regardless if I specify the voltages together or individually (eg. -cvddc 800  or -cvddc 800,800,800).

I have reinstalled drivers, reset all the settings for all cards in radeon software befopre running the miner, etc etc.
It feels almost like 2 of the 3 cards have some kind of different hardware on them that regulates voltage and isn't very well supported by phoenix, but that seems pretty unlikely given they're all the same brand and it's a new card...

I've been advised to use the -eres flag since my 6800s used to have problems when DAG regenerated.  I use -eres 6 and I've since found my cards to be a little bit more stable.

-eres <n> Allocate DAG buffers big enough for n epochs ahead (default: 2) to
      avoid allocating new buffers on each DAG epoch switch, which should improve DAG switch stability

Hi phoenixminer,

Hi everyone,
After a couple of weeks of waiting for shipment to arrive and after a couple of days of working I got these results for my XFX RX 6600 SWFT 210 :

It is a kind of a disappointment for me because I heard these GPUs should be, the best power-efficient on the current market, doing 30Mh/s for less than 50 Wats. Unfortunately, so far, this is not true. My Gigabyte RX 6600 XT is more power-efficient. 

Is anyone has better results for AMD RX 6600? Please share.
Thank you.

I have exact Type of 6600 and PM reports 55W. I am using Windows. I saw one reported with Reddit that their GPU reports 44W with HiveOS. May be different brand.

Thanks for the answer.
Do you get at least 30 MH/s? I can't go over -mclock 1890 MHz, and my hashrate stays under 29.50 MH/s.

If you're using just one card and using it as a display output for windows you may lose a few hashrates. Use the iGPU and the display output from the motherboard so you can fully use the GPU for mining.

[ironmanred]

Thanks for the answer.

I haven't noticed anyone reports that they can get 30mh for 6600 Non-XT. I think PM shows the highest number. Mine is about 29.4Mh from the miner. Most people say 28.9 to 29.1Mh.
I set mclock to 1900 in config and the GPU actually runs at 1890Mhz. I tried using Radeon software for OC and set memory clock to 1900 maximum, the GPU still runs at 1890. I guess that it is the limit for this GPU.

Does anyone know when exactly ETH becomes PoS ?
And when it's happens what coin is good to replace in our mining rigs (especially with AMD Polaris GPUS) ?

No one really knows as the devs of Ethereum are well known in missing the deadlines they pone to do.Based on that I would say as a minimum can happen in late 2022 early 2023 so there is enough time to keep mining Ethereum and making money like all miners do.

Plenty of other coins to mine if Eth goes PoS and the top of them are,ERG,ETC and RVN.

how about mixed pos + pow is it still an option discussed?

Thanks, I thought it's close because Ethermine keep posting stuff about their new Ethereum stacking pool in their Twitter and also MEWWallet keep advertising different staking methods.
Honestly I'm really scared that what's gonna happen in ETH PoS and that's why I can't risk staking any amount of ETH either solo or in a pool because how we can be sure that price of Ethereum doesn't decrease after PoS update or worse how can we be sure that their programming are perfect and can't let hack attacks like what happens to doomed destiny of BitcoinSV?

I think that having both PoV + PoS at least for a while after introducing PoS is a good idea that Ursul0 mentions.

I believe that's what is going to happen. PoW + PoS will co-exist for a while, but PoW block reward will be getting slowly so low or so hard that it will not be worthy to use it until it will cease to exist. And we will probably have testnet of PoS before it get launched to iron any issues it might have.
As for miners, ETC and RVN are strong candidates when ETH leaves PoW, as many GPUs that can't mine ETH anymore still can mine those just fine.

Yeah, it's the same as mine. My decision is made, I am looking for RX 6600 XT only.

I don't think is losing more than 0.5MH/s, but anyway, I use iGPU on all my rigs. This is my testing PC, where I am testing the OC before I set it in the rig, to minimize the downtimes.
