Hynix memory is the shittiest one of all. My rx 470s takes 20-25w more than others and still under perform. Crash after overclocking memory 1950. Do not accept -offset. Useless cards for mining. Elpida and samsung are far better.
If you increase core n memory hashrate willl go till 750 but make sure about hw werrors. Or else they wil crash in few mins. I tried fo figure this out by wasting few hours. Nobody helped me how to do it.

Any ideas ?

Change "miniamd" to a number like "1" and try.

I know it is for me. I checked SC recently. It takes 100W for 1200M. Also great way to unify the temps using -dcri
EDIT: https://tinyurl.com/z9pkv8o
... why not... sometimes I do, in any case cards are at 69C and fans all below 70%(on 480), on 470 fans on average at 45%
I also think that the few % gain on ETH between dual and single mode are real.

Glad to hear you're working on an update, claymore! Any chance you can add auto detect in ethman so it knows what client we're running? You could have 3 speed ratings available in the rig properties, ETH/ZEC/XMR so the manager keeps up when we switch algorithms.

While non-RX cards was doing great on v9.6, unfortunately very unstable for RX cards.

I've got a few RX 480/470 rigs running perfectly on 9.6, think it might be something to do with your setup. Here's an example of a 6 GPU rig running for almost 3 days straight:



Rig is running W10 4GB RAM 16.11.4 with 4x 480 and 2x 470, all have modded timings.



Excellent cards btw: refs470 with samsung (1625 into 2000 and 850mv all)
It can be very stable (it never restarts or hangs, there were some app crashes and unsuccessful miner restarts that I got fixed upping the voltage to 880mv) 4x470 on asrock btc r2:
EDIT: there's asus rx470 in slot with hdmi dummy

However 6 cards 2*480 and 4*470 (mostly hynix) on asrock latest (and discontinued) anniversary gave me hell. Among other shit I got banned from dwarfpool(didn't check the banned IP yet, so dunno for how long) because of lowdiffculty ... I guess... Btw the same system does ZEC and ETH solid

HYNIX SUCKS BALLS !!
literally I hate all of my RX480 hynix..!!

Just a word of caution.. Cryptonight is more correlated with core clock. So first the highest core clock at which your 1900 mhz memory maxes out. Thats your core clock for 1900Mhz.. Note the wattage (which usually changes with the core much more than memory).  So basically now edge core clock +20MHz and find memory that maxes out with that core clock. Then nudge it 10Mhz again and calibrate memory.

Alternate approach is use 2000 memory clock and which cards fail first. Note those and bring those all down with a factor of -25Mhz. So basically if you decide 1950Mhz for all cards.. those bad cards will be at 1925MHz. So thats the thing for you..
Either calibrate from high to low or low to high.. Once you find stable values that don't crash at least for 1Hr.
And then Believe me.. Decrease your memory clocks by 20Mhz more !!! and then leave your cars run overnight. Dont tweak the power settings after that.. ! So you will be at higher power settings for lower clocks..
I am hating hynixes   Angry Angry Angry Angry Angry Angry Angry Angry Angry Angry .. using 20W more than all my reference cards for 1 MH/s lower hashrate.
But with above strategy atleast its stable for a week!!


I 'm aware of the core speed being the key.
Also I did noticed that lowering mem clock to stock values (which works just fine with ZEC, as it's even more computational dependent) on XMR reduces the hashrate, as well as the stock relaxed mem timings. However I didn't have time to lower the mem to it's limit (the coers I run at 1180 to 1040).
Maybe will try sometime, thanks for the tip!
All my 470s make 700H+-@105W , ZEC 205H@125W and dual eth 28@144W

Hey one question.. Do you think dual mining is still any profitable? I think faster ETH mining with cool cards will keep longevity of the cards. And 144W is pretty high. with ETH only it takes 120W so basically additional 25W for max 8 Cents per day per card. Which almost neutralizes the benefits

Like I said in an earlier post - I worry about the upgrading of this miner because of all the possible RX cards it will potentially add to the XMR network - making the difficulty skyrocket just like it did when they all appeared on the ETH network, but I guess it's inevitable and Claymore wants/needs his dev fees - he doesn't have to worry about difficulty, he just wants as many miners using his software as possible.

Anyway - I'm hopeful the upgrade will add features and improvements for those of us who have been using this already for a while on R9, R7 and even earlier cards.

Does anyone have any tips or suggestions for the -a and -h settings for R9 380 (4GB) cards with this software. Right now I have them at -a 4 and the default -h and they hash at about 550h/s. I have them core underclocked to 800 (just because it always made no difference when I mined ETH and saves wattage).

Does XMR respond to memory over/underclocking much? It doesn't seem to matter if I have my 290s at 1125, 1250 or 1375. Or my 380s at 1425 or 1500.

On your 380s, copy the 1500 memory strap to the next higher one and run the miner at 1070/1600, should get you at least 610.

when you say "copy the 1500 memory strap to the next higher one" is this something requiring ROM modification or can I just put -mclock 1600 -cclock 1070 into my startup bat? I read a lot about "memory straps" all over the place but haven't done a lot of research into what that actually means. I have been running them at core 800 mem 1500 just using -cclock and -mclock

ROM modification.  Look here for more info: http://nerdralph.blogspot.com/2016/09/advanced-tonga-bios-editing.html

If your system stays stable you can push the memory to the top of that strap with 1070/1625 for about 617 h/s.


I use 5 R9 380's and get them from 630 to 650 Kh / s Control via msi afterburner cclock 1040 and 1650 mem clock, - 100mv

Good data Carlo... my 6x470 rig was running solid over 24 hours at 1200/1950.  So yesterday I decided to try bumping to 1200/1975. It seemed fine but then I woke up this morning and found that it had crashed overnight.  Also, there was not really any notable h/r increase when I pushed them from 1950 to 1975, so I have them set back to 1950 now.  But, I will watch this closely given your comment about 1920.  No sense risking more down-time, especially for little or no h/r gain.

Yet another person with older cards trying to be greedy by hoping a miner is not updated to optimize current gen cards lol.  It's a bit comical to me, especially because your whole premise is flawed... well, at least the way you state it is.  Claymore updating this miner to get more out of rx 470-480s will not result in a ton of new XMR miners flooding the XMR market and skyrocketing the difficulty. XMR has already been the most profitable coin to mine for close to a week for those of us with 470/480, so improving this miner may only result in a few more in that boat jumping over to XMR, assuming the gains are notable.  What you should and probably are more concerned with is that your "piece of the relative pie" is going to shrink.  I get it, and I know i will be in that boat eventually myself, but this is the way of technology.  Suggesting that Claymore not update this for current gen GPUs so that you can keep your "edge" with older cards really comes across as sour grapes.

you need to use either your payement ID or the full wallet.paymentID if you wish to see your XMR wallet on dwarf

so either this
https://dwarfpool.com/xmr/address?wallet=5acbcd29dcb4c9b0789feb4ef37d4cd8216514f361672f22d9f7c6dca9e68797

or this

https://dwarfpool.com/xmr/address?wallet=47sghzufGhJJDQEbScMCwVBimTuq6L5JiRixD8VeGbpjCTA12noXmi4ZyBZLc99e66NtnKff34fHsGRoyZk3ES1s1V4QVcB.5acbcd29dcb4c9b0789feb4ef37d4cd8216514f361672f22d9f7c6dca9e68797


I think the minimum payout is 0.1 XMR, so maybe you weren't there when payment occured today, see tomorrow if it's paid or not now that you've reached 0.1+ ? if still not open a ticket to them Smiley

whats the min. payout from dwarfpool, if using exchange address? Is it 5.0 or 0.2 xmr? Website is confusing. 5 xmr would need at least 40 480's

Well i think that's pretty clear

"If you mine direct to an exchange, then payment will be from 5 XMR once an hour or once every day"

So if you have a very very powerfull mining farm, they will pay you 5+ XMR per hour.

If you are a normal miner and generate less than 5 XMR/day , you will be paid your mined XMR once a day.

to sums up

+5XMR/day = payout every hour as long as you have 5XMR or more unpaid.
-5XMR/day = payout every day.

Yes, if you switch to daily payouts you'll get paid as soon as you reach 1 XMR so no need to wait for 5.

Isn't the daily payout the default ? but yeah you could check if you are indeed in daily payout mode (in your dwarfpool wallet page, you need to enter IP/mail in the lower left box to change things like autopayout, make a manual payout and so on)

Like I said in an earlier post - I worry about the upgrading of this miner because of all the possible RX cards it will potentially add to the XMR network - making the difficulty skyrocket just like it did when they all appeared on the ETH network, but I guess it's inevitable and Claymore wants/needs his dev fees - he doesn't have to worry about difficulty, he just wants as many miners using his software as possible.

Anyway - I'm hopeful the upgrade will add features and improvements for those of us who have been using this already for a while on R9, R7 and even earlier cards.

Does anyone have any tips or suggestions for the -a and -h settings for R9 380 (4GB) cards with this software. Right now I have them at -a 4 and the default -h and they hash at about 550h/s. I have them core underclocked to 800 (just because it always made no difference when I mined ETH and saves wattage).

Does XMR respond to memory over/underclocking much? It doesn't seem to matter if I have my 290s at 1125, 1250 or 1375. Or my 380s at 1425 or 1500.

On your 380s, copy the 1500 memory strap to the next higher one and run the miner at 1070/1600, should get you at least 610.

when you say "copy the 1500 memory strap to the next higher one" is this something requiring ROM modification or can I just put -mclock 1600 -cclock 1070 into my startup bat? I read a lot about "memory straps" all over the place but haven't done a lot of research into what that actually means. I have been running them at core 800 mem 1500 just using -cclock and -mclock

ROM modification.  Look here for more info: http://nerdralph.blogspot.com/2016/09/advanced-tonga-bios-editing.html

If your system stays stable you can push the memory to the top of that strap with 1070/1625 for about 617 h/s.
