Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[Xardas2014]

Hi I just recently picked up a few msi rx470 4gb and they run very stable but I'm running about 20mh with stock clocks and no mods what is the best way to get some more speed I'm used to playing with r9s so the rx cards are new to me thanks for any help

The real starting point is to mod the vbios. Short of that you are just tweaking your command line and clocks, which will only do so much without the mod.

All of my DCR shares are getting rejected using 9.0. I mine on supernova (dcr.suprnova.cc)...any idea why? It has been working fine with 8.1.

I believe this problem is related to this pool, sometimes it does not send response to auth message for some reason but still sends jobs, so miner mines but pool does not accept shares.
Miner will reconnect automatically after 10-15 invalid shares, usually the pool accepts auth message at second attempt.

Suprnova Decred pool is complete and utter garbage.  It should be blacklisted from the internet. I would get 95-100% rejects on most rigs, best case like 5-10%. Switched to coinmine, now get under 1% reject.

Some suprnova pools are ok, many are junk.

Totally agree!  In fact, I tried both DCR suprnova & decredpool.org and both were all over the place and far from producing consistent results!  After changing over the coinmine.pl it has been rock solid! Very few rejects and very consistent results day over day that match almost exactly to mining calculators. I was very impressed with coinmine on my Baikal FPGA and have been equally so with their DCR pool! Highly recommended!

Is there any reason to upgrade to 9.0 if you've got old GPUs? (280/290 etc)

Huge DCR performance boost on 290 when dual mining, you might be power limited though.

I have R9 390 and I'm using 8.1 but there's no rela difference from 7.4. When I try v9 it only works with same or less eth speed and same dcr speed, it can double the dcr speed but no matter what I do, it crashes the whole rig in about 10-20minutes, tried lower ethi, lower dcri, more vdcc, if it has more hash than 8.4, it crashes.

Something is limiting it, you need to find it yourself. No crashes here, it just starts throttling when it hits power limit. +50% to numbers below and still power limited.

How much more power does V9 draw compared to the previous one? right now I'm testing with -3.3% eth speed, +33% dcr speed, removed undervolting completely and gave +20% powerlimit, haven't checked the wallmeter but if this needs 40mv more, that's gotta be at least 10% more power.

Hi Guys, this is my first post here on bitcointalk.

I have been using claymore 8.1 for a while now, on a rig with 6x RX470 with modded bios, and was getting around 169Mh/s stable.

with claymore 9.0... this is awkward, i can't seem to get more than 44Mh/s, tried dcri from 1 to 40, no changes whatsoever
Increased ethi to 16, same thing.. nothing changes.

Am I doing something wrong here?

You didn't mention your rig stats, such as PSU, OS, your command line etc. so I'll take a WAG at it. Version 9 draws slightly more power than 8.1. so I would suggest using the -li command line option. If the rig runs better at something like -li 5 you can toy with that to get the best speed you can........and know your PSU isn't enough now. Other than that, I got nothing for ya.

Thanks a lot for your input, I fixed it, anyway, the rig stats are 2xEVGA 750W PSU's, 1 for each of the 3 cards, and one also has the mobo, 6x RX470 Nitro+ bios modded (didn't push too much, they were making 28.1/2 mh/s stable for weeks now, only ETH

The problem was that i hit the stuck 300Mhz GPU Bug for some reason, DDU + 16.11.5 drivers (the last ones that accept modded bioses)

Re-tested, and now using -dcri 4, and doing around 171MH/s total

ETH - Total Speed: 171.024 Mh/s, Total Shares: 17, Rejected: 0, Time: 00:07
ETH: GPU0 28.469 Mh/s, GPU1 28.524 Mh/s, GPU2 28.508 Mh/s, GPU3 28.502 Mh/s, GPU4 28.491 Mh/s, GPU5 28.530 Mh/s

I Noticed this because when I went back to Claymore 8.1, it was slow as hell, so... checked the monitors/sensors, and almost slit my wrists, stupid driver bugs that shouldn't even exist!

P.S.: this is my cmdline : EthDcrMiner64.exe  -dcri 4 -cclock 1150 -mclock 2050 -retrydelay 5 -tt -85,-85,-85,-85,-85,-85 -epool eu1.ethermine.org:4444 -ewal 0x31158768c36b20d84cE69354E52c25490ED4282e.Rig1 -epsw x -mode 1

Pretty profitable to mine ETH+DCR currently on the 470 4GB. Pretty much less than 2 months ROI. Probably won't last.

28.4MH/s ETH + 764MH/s DCR  (DCRI 27) (Default ASM setting)

[gaalx]

At 9.0 there are now such saws. 480 8 ref 1150/2100. At 8.1 was not. Driver 16.6.

@Claymore, what does it mean? Which GPU? There are 6 ones. Why? ( I expect GPU5 because of the temperature, but...

Every GPU has two threads.

I mean this:

Code:

18:01:21:376	13a8	WATCHDOG: GPU error, you need to restart miner :( 

It does not say, which GPU is failed.

Yeah, its been like this for a while now, when altcoins started geting crazy, although decred was a bit behind.
Still not sure if this is just a bubble or not, the prices seem to be holding on for a while now.

Can I write -allcoins UBQ? This command will work only with DUG UBQ?

Hi! My first post. v9.0 is rock solid on my rigs  Yesterday I bought 3 rx480 GPUs. Is is possible to both have 280X and rx480 on the same rig (Ubuntu)? Searching on the internet gives me both yes and no.

[Stingfisher]

Can risers with SATA connectors handle ETH+Dcr power use at default (no underclocking)?
I have power reserves, but afraid that risers might give up.

Anybody with sapphire Nitro 470RX 4gb, 8gb and/or MSI RX 470 4gb gaming X ON RISERS doing this double mining at the default power?

Whether you ETH solomine, dual mine, or even overclock your RX series it makes no difference in the amount of power from the PCIe motherboard slot because it only powers the memory, the rest is taken from your PCIe 6/8 pin power.

I think it always used 50 Watts last time I measured the current.

In my opinion 50 Watts is too much going thru SATA. It was ok with a R9 280X because those used max 25 Watts from the SATA connection, with a RX its never a good idea.

Nice to know. Does this apply to both the 8GB and 4GB versions of RX?

Hello ,

Remote manager is not compatible android?

You do not know an application capable of doing the same work as remote manager?
thank you

[Dowper]

At 9.0 there are now such saws. 480 8 ref 1150/2100. At 8.1 was not. Driver 16.6.

Nearly the same for me with a rx 480 red devil 8gb 1200/2250 and Driver 17.3.3 i guess

Same with Sapphire RX480 8GB Refference, the memory controller load is going to 75% for a few seconds and then again to 100%. There was no such problem with 7.3 which I was using before 9.0.

hi guys
link claymore v9 for windows is not here?

not see

look on 1st page

@Claymore,

Could you please check memory controller load? As others stated some cards randomly gets lower load on memory controller and this causes decreased hashrate.

For instance, my average hash rate should be around 264,5 MH/s for my 9 gpu rig. But it displays effective hourly rate around 205.0 MH/s.

I have tested this for more than 7 hours and this is the case for me. Even on ETH only mining using fine tuning and low power bios.

If you see low values on pool, miner must show low speed too. If you see that speed is not constant in the miner, change -dcri value, there are some border -dcri values where it can have unstable speed.

Thanks for the reply.

I have already specified -dcri value and found the best setting with -7 for ETH only and -25 for dual mining. However, even using these settings speed on miner drops and goes back to actual rate from time to time. So to confirm you, speed on miner drops and pool is affected from this as a result.

I'd think my gpus are bad but as soon as i switch to an older release (8.1 or 7.3) ETH only mining is stable. Dual mining is also stable but I'll lose the speed boost you provide with 9.

Also it can be bios or throttling. If you are sure that it's not the case, use "-asm 0", I don't see this behaviour on my GPUs and don't have other ideas how to fix it, sorry.

Is that nVidia?
