I frequently observe the GPU usage dips to 0% for 0.5 second and recovers to 100%. My hash rate should be about 27.8Mh/s, but with these dips happening, it sometimes drops to 24Mh/s or even 8Mh/s
Anyone notice this? I'm running on Rx570 with moded BIOS.

Which PSU is best for 6x rig with AMD RX5xx series, MB will be Biostar TB85.
Why not 2 of 750W ? I found some German (not Advance) with PFC at 50€(55$) . you can connect them with some ATX coupler (AddPSU, Dual PSU)There is some controversy about whether you should plug the card and the riser on the same PSU or oppositely all risers with the MB, and card where you can.
By the way, be careful before starting, ETH have gone so high, mining power exploded, and then difficulty. My date of benefit get worse since the bull rally (I got 1.9-2/month, now 1.6-1.7/month). Be careful. Dual Mining seems interesting.

what is now best for ETH, RX480 is sold out, RX570 or RX580 ??
I need 24-25pcs of cards for 4 new rigs.

Buy just 1 RX5xx first. Make sure that you are happy with these. I have found that they are MUCH LESS EFFICIENT that the previous RX4xx Series! Do this before you buy 24-25pcs of cards.
As far as the PSU, EVGA is always a good choice with a little higher price. This is my favorite on Amazon:

Less efficient when underclocked to the same same clock/voltage? I could swear I saw reviews online testing both @ 900mhz and the 5XX had >20w less power usage.

Hi there, msi rx470, with 16.11.4 I have blue screens and frezze , with 16.10.1 and 16.9.2 100% fans issuses. I'm mining for a year with these two versions of drivers, but now I have problems with one rig. What driver version is recomended, can anyone help me? All cards working at 0.98v, msi ab controls fans, clocks and voltage, hynix 1100/1900 and samsung 1100/2000. Rig with problem is Intel g1840, h81m plus, 4gb ddr3, 4 x msi rx470 4gb hynix.
MSI RX + Hynix ram = 5 weeks and counting RMA for me. MSI sucks balls.

I have 2 rigs now on ethOS. Today I decide to make another 4 rigs on ethOS all with Claymore miner exactly. I have combinet electricity, solar panels about 6-7kW (maybe I add next 2-3kW this year) and pay electricity for about 0,15 EUR/kW.
But I do not find on stores some good RX480 8GB (XFX, Sapphire,...) and I need 24pcs for 4 rigs. Do you have some tips where to find them or they are sold out ?
If yes, what to buy ? RX570, RX580 or RX470 ?
RX5xx series have 1x 6 pin and 1x 8 pin power supply, which PSU is best for 6 card in one rig ?
thnx for help

can you tell me more about your solar panels? How is it all configured? Do yo have batteries? What happens when there is not enough sun?
I have this: https://apsystems.com/
30pcs panels each 270Wp, 15x mikroinverters, without batteries, when no sun or not enought sun power, electricity go automatically from electric network
whats the total kwhr rating on your system, solar omly works for small installations not even a mid sized farm

If you guys are using ethos you should choose sgminer-gm as your default miner NOT claymore! You will get more hash rate for the same or less power consumption but without Claymore's fee.
I have an ethos rig with 3 x 290, 2 x 290x and 1 x 390. They are all clocked at core 1100 mem 1125 and sgminer-gm gives me 188mh/s while claymore gives me 180-183mh/s
I try it tonight ..... and write

When I use ETh solo mining I get a very stable 69 to 75° for my cards.
When I use dual-mining ETH+DCR, though, temperatures raise above 80° and beyond super quickly.
Now, I already use undervolting for all cards, but even when I tried to reduce the + GPU Frequency from about 5 - 7% to 1.5 - 2.5% it still raises in temperature very quickly. Is this normal?
Do I need to decrease mining intensity?

Yes its normal, it uses more power so it will generate more heat.
Try increasing fan speed manually if you are concerned.

Anyone else having their effective hashrate drop this low? It was like clockwork for months.

Yes, mining is like gambling Sometimes you are lucky and find a lot of shares and your effective hash rate goes way up, but sometimes you have unlucky streak and your effective hash rate will go very low. In the end it should average to your actual hash rate or very close to it over time.
Here is my current chart.
https://image.ibb.co/kyyLLk/hash_chart_eth_09may17.png
Same here.
I doubt it's an unlucky streak, since I know several people that are experiencing the same thing since a couple of days.
The number of shares just dropped by about 20% a couple of days ago on ethermine.org pool.
What could be the reason?
I'm also on ethermine and my last 24 hours looks like yours. The higher your hash rate the more noticeable the drop. My effective hash rate went from just under 1GH/s to 942MH/s. If you look at the stats for the top 10 miners on ethermine, you'll see that almost all of their charts show similar drops.

Hello;
I started mining some weeks ago and modded rom of my RX480
Sapphire RX480 8GB Nitro OC+ (11260-01-20G)
with Dual Mining
ETH 30+ mhs
DCR 840+ mhs
GPU-Z power Draw around 100W
%30 Fan Speed for 70 degree Temperature
Can you give any idea of these values are OK?

Although I doubt fanmin works at all because Claymore miner never report a fan speed @ 80%, always less. Usually 70-75% and one card at 50% fanspeed
On my Sapphire 480 and my former MSI 470 -fanmin have been definitively working, but speed was always a little lower than set.I also used -tt to target temperature, and it works.
however I never seen anything change, good or bad, speed, stability, power, heat, by changing mclock or any over/under clocking, under/over volting (-cclock -mclock -powlim -cvvdc -mvddc) .
I use latest amdgpu pro v17 drivers (Claymore advise v15 but it does not work on my Ubuntu 16.04), and maybe it does not work.
I've heard of atitweak to tune GPU in Linux, but it seems no more maintained.
If you are on Windows, maybe does a tool like Wattman or trixx, afterburner, who update your GPU config behind the scene?
With trixx I noticed the same behaviour. (I could actually see the Mclock value changing back to 2000 instead of the 2150 I set trough the commands). I will try it with MSI AB maybe that helps.. Thanks!

Hey all,
I'm new to Eth mining. Just wondering what I should expect from two Sapphire 7950's @ stock speeds? I'm presently getting 11 Mh/s from each card...
I'm using Claymore on a Windows 7 x64 Machine with the latest Catalyst Driver.
From reading previous posts I see people getting 20 Mh/s but is that from many DAG Epoch's ago? Just curious what folks are getting these days with 7950's
Let me know, thanks!
The best way for you to mine ZEC and take about 280Sol per card. It is more profitable.I'm new to Eth mining. Just wondering what I should expect from two Sapphire 7950's @ stock speeds? I'm presently getting 11 Mh/s from each card...

Indeed... I have mostly RX480 cards but I still have 2x 7950 and 1x 7970 from mining back in 2013 and those cards only do well on ZEC. So I leave them on that all the time.

Hi all, I have a weird issue with one of my rigs and I hope some may sound familiar and can be fixed;
I have one rig with 6x rx 580's (with bios mod) happily dual mining in windows 10. With bios mod they to 27 mhs, with parameters set in the config file they do 29.5 mhs. It appears that overtime, it can be 5 minuts or 12 hours, something kicks in and resets the values I have given the miner in commands and they go back to 27 mhs.
These are the parameters;
-cvddc 980
-mclock 2150
-fanmin 80
Although I doubt fanmin works at all because Claymore miner never report a fan speed @ 80%, always less. Usually 70-75% and one card at 50% fanspeed
