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

[merc84]

server PSUs are NOT setup like what we are talking about here. they have special load balance/failover circuitry.

you CAN fry stuff with multi consumer PSU setups.

but... suit yourself

As i said I am no expert so I simply ask the questions so i can understand, if you can explain the reason for this then please do so but "suit yourself" is not helpful thanks for nothing...

Edit: There seems to be some miss information going around, someone earlier posted an example that shows setup as I have currently used, if what I have setup is incorrect i would like to fix it, if you can elaborate on the reason that all powered riser should be connected from primary psu then please do so.

my apologies. no disrespect meant.

the different psus will have slightly different 12 volt outputs. that difference can lead to current flowing between the 12 volt outputs. the current can even be backwards from normal. if that current goes through the wrong component damage can happen.

its too much to explain simply, and its easy to get away with doing it wrong. and loads of misinformation on the net, so its easy to get overloaded.

Thanks for the reply, i do believe you as i have had some risers die (only after a year or more of use however) though if anyone can chime in with a detailed explanation so i can fully understand it I would appreciate that. Meanwhile I will correct my setup so that all pcie risers are powered from the primary psu. Does anyone know how many amps powered risers draw? Googling around suggest 3amps per riser.

I know this is slightly OT but it seems relevant to all us miners regardless of which coin we mine or which miner software we use.

My only concern is that powering all riser from the primary psu may exceed its rating on the 12v rail, I have 1000w Enermax Plat psu which is rated at 83amps on the 12v rail.

you are talking about the add2psu adapter?

just multi psu setups in general.

whats a add2psu adapter? got a link?

sorry bit busy today in this dang Real Life (tm) thingie.

EDIT: oops getting a bit OT here. sorry claymore.

anyone want to start a separate thread?

there are 3 config for multi psu:

1. connect mb, all riser, ssd and leftover gpu on pss1 and psu 2 only gets all gpu it can handle
2. connect mb, only the riser from the same gpu, ssd and gpu to psu1 and psu2 gets gpu + the same riser

which one is unsafe? 1 or 2

3 connect both psu to the same ground http://add2psu.com and dont worry about where to connect, use config 1 or 2

I would not be running more than 2 gpu from that psu it has a max rating of 62amps on the 12v rail. 3 gpu may well be drawing more than 62amp depending on model and clocks etc.

thanks i didnt consider this.. this may be the reason why 6 gpu dont work and 5 do on my h61!?

but 5 gpu, 4 riser i only draw 883w ..

this is my gpu
http://www.sapphiretech.com/productdetial.asp?pid=B520A2A6-4D37-4499-9584-B6BE8823AAC0&lang=eng
no mentions of amps on the 12v rail

Googling around suggest a 280x (same as 380x) draws upto 38 amps, the technical specs on ur 750w psu say the 12v rail is rated for 62 amps, if it is true a 280x draws upto 38 amps u could already be close to or exceeding this with just 2 gpu connected and nothing else.

hmm.. im currently running 5 of the saphire gpu, 3x gpu on psu1 including riser ssd and mainboard molex and 2 x gpu + riser, 3rd (6th) gpu gets recognized in linux but mining quits with memory access failure

yup claymores miner must rock on multi gpu systems. Im just mining on my single gpu daily driver pc.

if youre gonna go hardcore with powerful systems look into server psus

sidehack has some good kit:

Hello fellows. Is anyone using nanopool? i have few questions. does reported hashrate working for you? and how to setup email notification?
thanks

You're creating a feedback loop with your current setup.  PSU1 needs to power MB, CPU, and All Risers.  SSD or HDD may not have to be on PSU1, I have it both ways and they work fine.  PSU2,3,etc need to just power the cards.

See here    https://www.reddit.com/r/litecoinmining/comments/1dvit7/the_powered_riser_problem_is_there_a_hardware/c9vmjpw

just google feedback loop powered risers and you'll find more info.

anyone this miner on windows 10 with a 390x ?
want to know if you get lower then 30mhs i'm on windows 7 atm

[bradli]

How can i fix load usage(100%) on gpu ?
It s move up and down.
Does Anyone know ?

I get 30 Mh I have 2 x 6 card 390's on windows 10.  Works like a champ.

[ExcelThroughKnowledge]

can anyone fill me in how does solo mining work?

When we find a block, we definitely would get the reward just that we need time to solve as compared to pool?

Or when you find a block, there are also possibilities that others found the same block and is rushing for the solution together and it all depends on who gotten the solution first? hmm..? I'm currently pool mining but would wanna  try out solo mining to see how it is..

Thanks in advance, sorry for such noob questions.. I'm still new!

Is there a mining pool that has both DCR and ETH that Auto exchanges to BTC? Mining Pool Hub is almost it but it does not have DCR.

Crashed my psu. Working dual miner ( 4.3 ) after 1 hour.
My rig: 3x R7 370 . Psu coolermaster 600w.
-
Dual miner 4.3 calistirdiktan 1saat sonra psu yandı. Tam yanma aşamasında kokudan farkettik kartları zor kurtardık. Anakart ve psu pert.
Kartlarin cektigi watt hesaplamasini dikkatli yapmak lazim. Benim gibi ucu ucuna yeten psu kullananların riski büyük.

I want to tryout https://minergate.com/ pool, which was one of my favorite from XMR mining, but I cant run your miner even with allpool option. Does your miner support this pool?

What did you expect with CM 600W...

It's not fault of CM 600.
R7 370 can suck up to 150W when in dual. 75W can come from PCI-e 6 pin, so another 75W (6,25A) must flow through PCI-E slot from motherboard. And this is only for one card! Make it times 3 and you get almost 20A flowing through motherboard. Risers powered directly form psu are resonable idea in that case.

It seems it supports HTTP only, so it is not supported. Anyway, mining Ethereum via HTTP is a bad idea.

May want to watch them I have been waiting for over a month on payouts and they just say keep sending email. Not to mention how fked the system is with miscount shares and disappearing hashrate and stratum configuration problems.

What effect on GPU does the the frequent restart miner in program EthMan. when I want to replace pool ?

It's not a problem for GPU if miner restarts often. But why do you want to change pools frequently?

[GRinvest]

You can make a change to the EthMan without having to reboot? make the a pool manager
