I would like to come back to discuss with all of you about the pools.

I'm currently only eth mining , and I've split my rigs between Ethermine and Dwarfpool.
I made some maths, and I got bad news : I'm loosing about 10% profit from what is expected with coinwarz.

About Ethermine, they always consider lower hashrate tha reported. They have the good reported hashrate , as shown in claymore, but the effective current hashrate is lower and profit reduced..

About Dwarfpool, their "Current approx.speed" is right, but "Earning in last 24 hours " is always 10% to 20% lower than expected from coinwarz.

I suggest everybody check his pools (if it's not already done).
Is there any ETH pool that pay as expected from the mining calculators ?

I use ethpool.org. I like that they pay uncles and every once in a while. You can hit. Big blocks. 8 or 9 coins vs 5.

All pool calculators tend to be far off since they go short term. Not long term so they are not accurate.

I have been using Ethermine. It says that It pays uncles, yet I have never seen one. I really like the ability to change the payout rate, but I am going to switch back to Ethpool.

WOW! Bitcoin Drop from $1066 to $931 in last hour and now back up to $980 due to China blocking all withdrawals in 2 exchanges.

and now the danger of centralization becomes more easy to see.

Would love to see China seize and destroy all gear in China would make for a really interesting year.

That would really make for a interesting year!!

Well gulf power finally came out of the closet and said they want to move rates up to 20c kWh so they can pay for food stamp users power bill
That's probably going to kill my mining days for awhile

Ouch! Sorry to hear that.

It seems like bitcoin is starting trend upwards a bit, the china news is having less and less of a impact on the price. The news was a pretty big bomb to drop on people, next thing will be if they decide to start locking down accounts or seize btc from people they think are breaking the laws. Since the begging of the year china keeps dropping negative news, but they can't seem derail the price train.

Hey if they did seize and destroy all the farms, imagine how crazy profit would get. Also how would you even go about doing such a thing, fill up a couple of barges then light it on fire in the ocean? lmao

Looks like India picking up pace on Bitcoin recently too -- imagine Chinese farms migrating overseas -- this will also boost up major ISP and hosting - esp the ones with cheap power.

In case Bitcoin would become complicated for chinese people, where do you guys thinks they will invest ? They surely won't stop trying to send their money outside China, and BTC in not the only way.
Maybe it could be interesting to speculate about the others Alts chinese people would use instead of Bitcoin if laws become too hard. Even if the Alts would follow shortly.

NB : thanks all for the advices about my little GPU problem, I'm going to check this week end. And thanks to Arielbit and Lonerangir for the interesting info about faulty risers and soldering flux.

speaking of a failing riser...i have one that i fixed last night (it was from 2013-2014 mining days)..

the symptom was, the card is detected (windows 7 64bit), but when it started mining the driver crashed, and that specific card will not mine like the others..

in troubleshooting:
usb 3.0 wire - good
power connections of riser to PSU and GPU to PSU - good
plug a good card - failed too
plug the card with issue directly to motherboard - it runs fine.

solution:
i removed the cover underneath the riser, there was no burn..it was the white stuff solidified along the soldered parts of the riser, i think it was from the soldering paste used in manufacturing those risers (must be creating shorts)...i just used a fine steel brush and brushed those white stuff away and everything is fine again.

That stuff is most likely soldering flux.

i made a typo error btw, i mean "and that specific card will not mine unlike the others.."

anyway...just pointing out a place where we can look for troubles

Corsair 750w (for 3 RX470)

I have the same problem even if I disable the 2 good working cards.

I have no idea left .. no big deal, just one GPU, but I like to have everything perfect !

So 1 card stand alone on the rig.

And it still does this?

Is it one of the ones I sold you?

Is it running on the evga mobo I sold you?

Basically sounds like a failing card.

Or a failing mobo.

Or a falling psu.

or a failing riser.

Risers have caps. And caps are like a rechargeable battery if they are failing they can cause your symptom.

I lose track of the inventory I sell. I know I sold 5 xfx 1 fan short 470s. They were flawless.

I also sold quite a few blower style cards to you. Sapphire if I recall. They were weird at times. Is it one of them?

Just received a new RX 480 sapphire nitro 4gb from newegg.

They changed the design and removed features.

No led lighting just a chrome sapphire badge now

No dual bios switch, so single bios now.

Samsung vram

The card default core clock is higher now at 1326 mhz

I looked in the bios and it looks nearly identical to rx 470 bios but is different from the previous rx 480 4gb bios. What I mean is that in the bios you see straps for 2 types of memory (hynix and elpida) but in my 480 it had one type of memory strap only (samsung). The memory types that show up...it doesn't look like the bios editor is showing the samsung or sapphire has hidden the samsung memory straps to prevent bios modding.

I can't recommend the 4gb 480 for now, originally got it over the 470 due to that it was the same price. Go for the 470s if you buy cards, it makes no sense they would change the bios like this.

(edit I use a modified bios editor that works on 470 dual vram bios, it will probably have to be modified again to work for this 480)

That sucks. I have chosen to not do any bios mods. Just ends frustrations you and many others have.

I am running all gear with simplemining. Xmr stable simple easy.

If I could see what good a low volt stock clock bios mod does I would consider doing one with low power in mind more then over lock.

I made a mistake had the wrong adapter. For some reason the adapter number in atiflash is different from my miner. I modded it and it is working fine.

I make simple mods, I copy over the memory straps which gives me a nice boost in speed on eth and very mild bump in monero. Then I use afterburner to drop the voltage and that gives me good results, a hard coded voltage mod in the bios would reduce it further but this method is rock stable and imo good enough.

Also I run full headless with no hdmi plugs and gpus on the pci x1 ports I can't OC the memory on those cards via software. So I bump the memory speed in the bios to what I want (1900mhz) and it runs at said speed.

If I could see what good a low volt stock clock bios mod does I would consider doing one with low power in mind more then over lock.

I use 2 "low energy" custom roms from Eliovp.
RX480s (ETH-29MH-low-energy) and R9-Nanos (-100mV rom)
Working very well, and saves me on power bill.

Although I have access to hydro power at my ISP in Labrador/Crytoboreas for my other BTC farm.... I cannot send my open cage rigs over because its not secured in a suitable chassis. The Pandaminer was a good solution but that's another story all together.

Since having the modded roms, I dont mess with Afterburner, Wattman etc. anymore.
And since moving my rigs to smOS Linux -- the custom roms were perfect marriage since no fiddling with Windows 10, GPU utilities, etc. And smOS will use use native AMD settings with the custom roms at Linux/Ubuntu/hardware level.

If you are not comfortable with modded roms, you can still use Afterburner etc to control the wattages. Ideally, you should try one of Eliovp's custom rom on 1 rig to compare notes. You can always change back to stock roms if unsatisfied.

For me, I took the scary jump to custom roms ever-since I saw my first power bill during the ETH craze a year ago....

I'm looking into modifying my own custom ROMs, but it's not for the faint of heart. Need to know the ROM layout, know which parameters to modify, and in the case of adding a negative voltage offset, know where in the ROM to add the offset. After all that, you have to regenerate the checksum of the file.

All possible, but takes a bit of a curve to figure out how to execute.

There seems to be a minority of people that are in the know, and they don't openly share how to do it. You can pay for customization, or figure it out on your own, or settle for what they openly share. I can't blame them, when it comes down to it, but I don't have to like it Tongue

I, too, use the LowEnergy ROM for the reference 480s I own, but I'd like to add a negative offset to some of my other "aftermarket" cards (480s and 470s) so I can move to a 6-card linux rig, and not have to deal with "windows", and enjoy lower energy usage.

https://www.macrumors.com/2017/02/07/apple-webkit-community-metal-on-the-web/

nice catch.. I will be interested to see how well the chips do.

my thoughts at for asic mining we stay at this size 14/16 maybe a second better chip by by bitmain. in summer 2018

then
2020 a 10nm
2022 a better 10nm

2025 a 7nm
2028 a better 7nm and at this point we would be done for shrinkage of chips.

I just seen on the news today as the press was reporting in the white house with President Trump and a bunch of CEOs of several corporations; the CEO of Intel Mr. Krzanich announced the building of a manufacturing plant in Arizona for the production of 7nm chips. I would expect the usage in GPUs, but I am wondering if someone is thinking that these may be used for mining?
