Ok, I know I'm a few days late but I finally have the numbers for the Sapphire Fury Nitros I promised last Thursday/Friday.  I was dragging my feet after Claymore hinted that v11.1 would include compatibility for asm with the 16.11.3 driver set.  I busied myself tweaking my eco rom for 16.11.3 which appears to have been wasted effort.  The implication being that I am unsatisfied with the performance of the "eco" rom, but will post the data with the caveat that I strongly believe there is room for improvement (and will work on further tweaks this week).

Disclaimer: This rig has several components that are overkill.  I have plenty of 'computer crap' collecting dust so I don't hesitate to grab things that work.  I guess I'm pleading that I don't have to waste time responding to posts about how i5s are stupid and/or PSU density is a waste of money.



CPU: i5 4570
MB: ASRock H81 Pro BTC R2.0
RAM: 8GB G.Skill Ripjaws X series DDR3 1600 Mhz
PSU: EVGA 1600 G2 (PSU1) & EVGA 1300 G2 (PSU2)
HDD: 128GB SSD with 20GB virtual memory
OS: Windows 10 Pro
GPU: x6 Sapphire R9 Fury Nitro 100379NTOC+SR
Risers: x5 Version 6 USB 3.0 PCIE Riser 1x to 16x
Riser: x1 Shielded 16x Riser Ribbon
Driver: Radeon Software Version: 15.12
Cooling: x4 Noctua NF-F12 IPPC 3000 (blowing on cards)
Cooling: x2 Corsair SP120 High Performance Edition (blowing on MB)

Configuration:
PSU1 - 3 Cards, 2 Risers, MB (including ribbon riser for the 3rd card), CPU, HDD, Fans
PSU2 - 3 Cards, 3 Risers

Required Info: The kilowatt meter on the left is PSU1.  The kilowatt meter on the right is PSU2.  Each GPU was delivered to the door for $271.81/GPU.

RESULTS

Bone Stock
1050/500



Hashrate: 2,503 H/s
Power: 1,657 W at the wall.

Analysis: Each card is drawing 271.33 W from the wall and producing 417.16 H/s.  The system is drawing a measly 30 W (the Noctuas are basically just idling).

H/W = 1.54
H/$ = 1.53


"Eco" Rom Installed
900/400 with -171mV & 50% PL



Hashrate: 2,025 H/s
Power: 885 W at the wall.

Analysis: Each card is drawing 142 W from the wall and producing 337.5 H/s.  The system is drawing 33 W.

H/W = 2.38
H/$ = 1.24

Summary: The goal is to crank the wattage down to 100 W at the PSU resulting in ~110 W at the wall.  To accomplish this I need to shave another 30 W per card, which appears doable.  The sticker is that I would like to keep it at or above 1,800 H/s in pursuit of a H/W ratio of 3.  If anyone has a Fury rom they wouldn't mind sharing I would be greatly appreciative.  Likewise, I am willing to share what I've been working on (more work to come).

Oh wow I have been away for a while due to work catchup and see that there is now a Claymore's Zcash GPUminer v11.1 I was last using 9.2 when I did some mining.

Hello, does anybody know about a good tutorial on how to install ubuntu and drivers for rx cards? i've been trying for three days without good results.

Power consumption  is the same on my RX480. However, on my 4 x 79xx consumption increased by 50 W. I measured with energy meter.

Simple explanation. Ping/traceroute from the location with the rejects.  I suspect you have high latency/bad Internet. Rejects tend to come from things like bad internet.

Also try a different data center for the pool you use. Most pools have more than one datacenter. One may be closer to you.  

In windows open a CMD prompt as admin.

type "ping your.pool.address"

Should spit out some numbers if any are 100ms+ that's bad.

For example:


You can also run traceroute.  In windows the command is:


Traceroute shows you every individual hop between you and your pool. Each hop will show how many milliseconds it takes for that hop. The higher the number the worse your connection to the pool.  Often times you have to go through one slow internet hub that slows down your whole connection.

Traceroute will also show you how many hops between you and your pool. The more hops the worse your connection will be. 10 is probably ok but 20 means you're more likely to have more bad connections between you and the pool.

If you use a different datacenter or pool you just change that part of the code.

Claymore, How could i set a low target, as you do for your mining fee?

ver 11.1 power on 4*470 refs
(not sure, but possibly it spikes a bit less now)



EDIT: one card there is with samsung memory and it goes up to 86W on VRM, while the rest are Hynix and all top at 92W (same settings for all)

My 290x at 1050/1500 do 315 h/s on 11 and 320 on 11.1. How do your cards do?

Hello Claymore, we are releasing new ethOS version soon. At the time of release, we will include the fastest linux miner available. If it is Optiminer, it will be Optiminer. If it is Claymore, it will be Claymore.

We have 5000+ rigs on ethos, that means your mining fee will be the equivalent of 100 rigs. Will you release linux version soon? The choice is yours.

6 RX 470
+ 5-10 sol. increase per card

Not bad

If you use Linux, stick with optiminer guys. You get max speed out of rx series.

Claymore has also made it pretty clear that no Linux version will follow.

Ok, so can you release the linux version that has no such limitations to what you can do with the asm, instead of continuing to develop for crap windows first?

For me v11 vs v11.1-
280x: 240-->245 S/s (2%)
390:   325-->355 S/s (9%)

Overall is speed improvement, depends of cards, for me notable speed increase is for 290/390

linux version please...

There will be.. Just time will tell.. Until they find how to optimize it.. Plssss claymore..

There must be a way

with v11.1 i am getting ZecMiner64 low memory error message but with v11 i dont get any low memory error messages.

going to stick to v11 for now.

RX 480 8gb OC Nitro+ stock bios -75mV

V11    = 260h/s
V11.1 = 270h/s

watt
v11 = 120watt per card
v11.1 = 140watt per card

stock Speed 1342/2000

11.0 -> 11.1
280 1000/1500 250 -> 260
290 1050/1250 330 -> 360
