US-West (Silicon Valley), US-East (NY), EU-West (London), and EU-East (Germany) are now all online.


I submitted my info a few days ago with no listing yet. Not sure how long it typically takes, but I figured I would at least get a post up in the forums and keep on top of discord while I waited.

Hey guys, I got tired of seeing all the hash at flockpool, especially now that xmrig is out eliminating the financial incentive. So I have started a pool with 1 stratum on the US west coast and 1 stratum in London. I will launch a US East coast stratum tonight as well. Perhaps one in Germany too for continental Europe.

The pool is free until April 2022 at which point it will only increase to 0.25% with a 3 monthly increase of 0.25% to a maximum of 1%. I am willing to eat the cost of these servers just to get people off of flockpool and support decentralisation of RTM.

I will also consider additional stratums if there is a demand. You can email me at admin@cpu-miners.com to discuss it further. Come on guys, help me spread some hash around, and pay nothing for doing it.

Have you sold the S9?

Fury runs best on 15.12 with asm enabled.  Stock clocks and bios gets you around 415 H/s

Buy orders total 1 BTC and the 24 hr trade volume is 10 BTC.  What are you pumping, your milk money??

Stock bios runs 2,500 H/s @ 1650W for $2,200 = ~1.51 H/watt and ~1.14 H/$ (price and power is entire rig)
'Eco" bios runs 2,000 H/s @ 885W for $2,200 = ~2.26 H/watt and ~0.9 H/$ (price and power is entire rig)

The 'eco' bios has a 50% PL with -125mV at 900/400.

I have a 6 Fury rig that runs 1650W at the wall with Gold rated PSUs (stock bios).  When I load an 'eco' bios on the secondary switch the rig runs 900W at the wall.  You may be able to get away with a single 1600W PSU, but if you're going to drop that kind of cash you may as well pick up a 1000W G3 and a 800W G3 for the same price.  You'd get a bit more overhead on the PSU to keep you under 80% (stock bios) and even get close to your 50% sweet spot if you under-volt.

Edit: The multi-PSU approach with new generation G3 also ensures that every single VGA cable has an 8-pin power plug.  An EVGA 1600 G2 only has nine (9) 8-pin power and then five (5) 6-pin power.  You'd also have to purchase a few adapters if you go with a single 1600W as you will need twelve (12) 8-pin for a 6 Fury rig.

I think in the short term this is going to hurt ZEC/XMR/ETC miners as difficulty increases.  That said, bolstering the physical infrastructure of a network usually leads to increased investor confidence.  I don't think enough new money will flow in to offset the difficulty, but I don't think it will 'kill' GPU mining in the long term.

Get ready to tighten your belts a bit and be on the lookout for incredible deals on GPUs from panic sellers.  Where some see doom, I still see opportunity.

Great have a great day

As others have said, "set" does not persist across boots whereas "setx" persists across boots.  I believe your error comes from not having the '='

set GPU_FORCE_64BIT_PTR=1

1100/500 -48mv should be a safe place to start.

I run a 6xR9 Fury Nitro rig with stock bios at 2,500 H/s rock solid.  The card on the ribbon riser does run about 7C above the other 5 cards (settles in at 75C while other cards sit at 68C).  This pushes the fans from a gentle 31%-44% up to 70% on that one card.

I have a meeting I need to run to but this thread I found may have some useful information in it.  I will keep digging when I get back as well.

https://forum.ethereum.org/discussion/5195/riser-1-to-3-pci-e-1x

Edit 1:

After reading through the above thread and taking a look at Intel's specs on the h81 and z87 it would appear that the max PCIE lanes through the h81 chipset is 6, whereas the z87 chipset can handle 8.  The 1x PCIE slots run through the chipset, but the 16x slot runs straight to the CPU. 

I would think that you could run 6 GPUs max through the chipset while running the remainder of your GPUs through the 16x slot using the CPUs remaining availability. In this scenario you could only ever use a 1x2 card in one of your 1x slots.  If you moved the 1x3 card to the 16x slot then you could run 5 GPU through the chipset and 3 (or more depending on CPU, driver, OS) through the 16x PCIE straight to the CPU.

But that doesn't seem to be your experience.  If you have the 1x3 card in the last 1x PCIE slot then the 7th card you plug in should be the 6th card running through the chipset.  Theoretically you should be able to run 7 cards with your setup, but not 8.  And you can't.

So I'm wondering, perhaps we have a bottleneck somewhere else?  Out of curiosity, what CPU are you using?

http://ark.intel.com/products/75013/Intel-Z87-Chipset

https://ark.intel.com/products/75016/Intel-H81-Chipset

Which PCIE slot are you connecting your 1x3 card into?

It is my understanding that each GPU requires a minimum of 1 PCIE lane/pipeline to transmit data.  That means you would have to plug the 1x3 card into a slot with at least 3 lanes/pipelines (in the real world that means a 4x, 8x, or 16x slot).  The H81 Pro BTC has a single 16x slot and five 1x slots.  You could only ever run the 1x3 card on the 16x slot.

If I'm wrong on this I am open to correction.  I've actually been wanting to play around with the exact setup you describe.

I have an 850 G3 and 1000 G3 coming in on Thursday. I can report back on my experience pushing furys. You may be able to find a deal on 2 850s for close to the same price as a 1300 G2. Or pick up vga splitters.

Why can't that be true? Because you've never heard of it? 50% - 70% is usually the best efficiency for a PSU.  Depends on the PSU and curve.  85% or less is recommended for a longer life-cycle.  I always aim for ~50% load on PSU understanding that demand usually increases.

Edit: And I currently have an 800W load on a 1600W PSU.  So I guess it is a thing.

I think the easiest way to disable auto updates is through the group policy editor.  Only need to select automatic updates and switch it to disabled.

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.

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).

I broke my only kill-o-watt meter around CM v8.0 or so and haven't replaced it.  I will get one next day delivered so I can update you.

Pure speculation from my previous tinkering and what others have reported: each card can easily get 300 H/s @ 100W (this was achieved in CM v9.0).  Running full bore at 400 H/s I'd guess it's 200W.  Again, this is pure speculation.  I will update when the new meter shows up.

Edit: Have 2 kilowatt meters arriving tomorrow.

I have 6 Sapphire R9 Fury Nitro on Windows 10 with 8 gigs of RAM and an i5 (I know it's overkill, it was just collecting dust though).

CM Version: 10.0
Drivers: 16.11.5
a: 2
i: 6
Hash: 375 H/s

CM Version: 11.0
Drivers: 15.12
a: 2
asm: 1
i: 6
Hash: 397 H/s

The 16.11 series drivers were always about 10% faster than 15.12 for the Fiji.  It makes me wonder if asm was compatible with the 16.11 family drivers could we get as much as 420 H/s from the Fiji?  Also, not sure if -asm overrides -a, haven't done any testing with it and the documentation is pretty bare.

Which driver version are you using?
What is your -a set to?

I have Furys that went from 345 H/s to 375 H/s (v9.3 to v10.0).

I have Win10 running 16.11.5 drivers with -a 2

Edit: I run -i 6 using stock bios and all stock clocks. Fijis are Sapphire Fury Nitro.
