2   Hash chip type: BM1580

3   Total quantity of hash chips: 135 PCS

4   Total quantity of hash boards: 3 PCS

5   Total hash rate: 4TH ±5%

6   DC voltage input: 11.60~13.00 V

7   DC current input @12V DC: 79.59 A +10%

8   DC Power @12V DC input: 955 W +10%

9   220VAC Power @25℃ ,93%: conversion efficiency of APW3, 1027 W +10%

10   220VAC Power efficiency @25℃,93% conversion efficiency of APW3:  253mJ/MH+10%

11   Weight（without package）: 3.05 kg

12    Operation temperature: 0-40 ℃

13   Storage temperature: -40-85 ℃

Just checking if the choosing one of the above make any future issue?

As with Ledger wallet it provide the option for both as was recommended to moved all from legacy to Segwit.

At Yobit the trading of BCD already on.

Will this be another surge like BCH/BTG?

or it will be a quickie RIP

Like to ask is it a great advantage with SDD as OS drive?

If using HDD, apart from the higher watt used, any other know disadvantages?

Reason is I have many HDD so if not necessary then will save the $ to use the HDD instead.

Thanks

Something cooking and out soon??

I have 2 GPU running with no issue.

When I added the 3rd GPU, the boot up not fail. it just gave a second beep as message.

Normally with one beep and it will start the booting up.

Any setup I need to do at BIOS?

Thanks

Updates:

Solved: just upgrade the MB BIOS and now have the option of 4G. Enable it and bingo!

Setup this discussion so we know the best way to max out the potential for this expensive GPU.

We know from time to time the profitability shift, so hope here can get advise and suggestion for near optimum profit.

Best Algo/hashrate:
Which pool:
which mining software:
current expected daily profit before electricity:
Any OC (core/memory):

Or any tips on extra mod:


23/Dec posted:
Maybe as we get this discussion further, I will group the list of Algo and coin that is most used by the 1080ti. To do this, might need some help from all of you as I might missed to capture what you have posted.

Could be like:

Current reported profitable coin:
- Date / Coin / Algo / maybe link to the coin or the miner?
- to ensure the list not too long, we will keep it within the top 20 reported by date. Any older date will be moved out (or I might put this to a google spreadsheet link)

As for the setting of the OC, I think just have to do own test as the variance just too large and every card is not the same

What other key info you believe should be in the 1st page?

I know many dont like to share the profitable coin as when it got listed here, likely is taking away the profit from them. but just post only if you are willing to help.

Any pointer here as i tried to follow the step to mod the BIOS.

But after success flashed and rebooted, the miner cannot see any OpenCL device and the same too MSI afterburner or GPUZ.
When I reflash to the original, all back to normal but the RX480 is still only with 24MH/s

Step is:
save the original BIOS as backup
Polaris editor to load the BIOS and edit by copy 1750 timing to 2000, save to a mod bios file
ATIflash and program the above and all shows success and reboot.

Then its not running as OpenCL device. I also upgraded to latest driver 17.xx and still not working.

Any pointer are appreciated.

Cheers

additional: this is Asus Strix 480 with 8G
CPUZ read it as Ellesmere

Current config
- Win10 64 bit
- using single RX480 fro the mod
- with latest 17.xx driver

Edit:
Updated the title to read clearly
added more detail of my issue and setup

With consideration of Power Cost and also the Cost of the card, which option has better ROI?

1. Single 1080Ti
2. multi RX (470 or 480), 3 or to one 1080TI?

3. consideration of near future GPU mining that support more on nVidia or AMD?

Thanks for the expert sharing and hope this clear the way to start a more profitable mining.

Electricity cost at 0.15 per kWh.
