Soldo is Soldo - nothing happens.
It will be mined as before - CPU solo only.

You can mine Goldo like Soldo - just download Goldo apps.

If you had Soldo at the your local wallet you have the same amount Goldo already.
Just open old Soldo wallet with Goldo apps and transfer all of the coins to new Goldo wallet address.

Its like ETH and ETC - different coins but with the same roots........
So which one is now fully supported by the devs? Future development will be made for which coin?

Copied from different forum, nonetheless thoughtful reading.



"am very concerned about incorrect and misleading information I am seeing posted on forums and the Internet in general about electrical specification for GPU mining. There are a lot of new miners building rigs and the AMD shortage is pushing people to use 1080 ti's and other Nvidia cards (up to 250 watt cards stock). You need to accept that there are individuals on these forums that make a profit off of your inexperience, and want to sell you stuff. That is not a bad thing by itself, but if facts are distorted and people make incorrect decisions, bad things can and will happen.

I am an electrical engineer with 30 years experience and I will simply present the facts in this post. I sell no mining equipment and have no motives other than to keep people safe in their mining endeavors. You need to make up your own mind what you think is safe for you, your rigs, and your home or facility.

1) New risers have NO power connection to the mobo, only data via the USB cable. They make their own 3.3V on the riser from the 12V rail. You NEED to test your risers to confirm this. Ultimately you are responsible for building your rig in a safe and reliable way. Not me, or any other person on this forum. Having said that, each GPU should be powered from one PSU (both riser and 8 or 6 pin connector). IF you power the riser from the mobo PSU and the 6 or 8 pin connector from a different PSU you can potentially tie together the 12V rail from two PSU's. They will fight to regulate the 12V rail if they are just a little bit off. No one, especially you, wins that battle. This can cause melted cables and fires. Others on this forum insist you must power the riser from the same PSU as the mobo. This is not correct and ties back to very early Bitcoin mining when the risers had power connections from the mobo. Just because you wire it wrong and it works does not mean you are OK. Most GPU vendors have circuitry to isolate the PCIe 12V rail from the 6 and 8 pin 12V rail.... if you have it wrong, and you find one that does not, you will not be happy.

2) SATA connectors and therefore SATA risers are rated for 4.5 amps on the 12V rail. The PCIe 3 specification allows a GPU to draw 5.5 amps from the PCIe 12V bus. A 1080 ti GPU draws 4.4 amps at 80% power (link below), and more than 4.5 amps at 100% power. Therefore a 1080 ti at full power draws more than 4.5 amps and you are drawing too much current through a SATA connector. Anyone who says that its fine, and perfectly safe to use SATA cables on risers with more than 4.5amps draw, has no idea what they are talking about, and absolutely no electrical engineering experience.



The older 4 pin molex connectors are rated at 11 amps for the 12V rail. Therefore, do NOT use the molex to SATA adapters. Run a 4 pin molex cable from your PSU directly to your riser get rid of the SATA adapter. Even if you power two 1080 ti's, and they draw 5.5 amps each (the maximum), you are still within the rating of the 4 pin molex cable and connector. Its simply not worth the risk to overpower a connector when it is so easy to use the right connector.

3) In the US an 8 GPU 1080 ti rig will draw about 90% load on a 20 amp circuit. In the US 80% maximum continuous load is code, and can deal with inrush current. Circuit breakers have one purpose: to keep the wires in the wall from catching fire from too much current. They could care less what is plugged into the line, if its on fire, or not, as long as it does not draw more current that the wires can handle. So circuit breakers do NOT protect your rig or your house from a fire, they are not designed to do so. Keep total current draw on a rig to 80% of the breaker. If you want to build big rigs with 250 watt cards run 20 or 30 amp dedicated lines. Don't try to plug different PSU's into separate residential 15 amp lines. Other countries with 220V mains line voltage is different.

A 7 GPU 1080 ti rig at full power draws 79% continuous load, perfect for a 20 amp line.

4) plugging multiple PSU's from the same rig into different circuits / breakers is a bad idea. If one breaker blows and its not the master PSU, you have half a rig powered. While not normally an issue, it could damage your cards, depending on how you have your rigs wired.

5) Molded SATA connectors (like the ones sold with risers) are known to have the internal crimp connections that can move in the molding process and can be close enough to each other to eventually short (even at normal SATA loads, not over rated). Heat will help to facilitate this. While this can take months or years, once you get a short, the SATA connector WILL burst into flames. Now, you have a fire. Don't use them, especially on 1080 ti's, just use the 4 pin molex connectors and cables from your PSU, or buy non molded SATA connectors for use with GPU's that draw 4.5amps or less.



6) Just because something works on one GPU from one vendor does not mean in will work on another. I do use SATA cables to power my Nitro Sapphire RX480 rigs (they draw less than 4.5 amps on the 12V PCIe bus, one SATA cable / GPU, non molded adapters). However, I do NOT use SATA on the XFX RX480 cards. The XFX cards draw more power from the PCIe 12V bus and will get warm SATA connectors. So each vendor has different power draws and you need to be very careful. If you do not know how to measure, just use the 11amp molex cable and don't worry. I have had a SATA connector get very hot on an XFX card (you could smell it).

Ok so that is all I have for now. I expect some backlash from this post, but if I can help one person avoid a dangerous situation I will be more than happy."


I'm using RX570s and 1080tis. Each power line coming from the PSU to the risers is connected to 3 risers using a SATA power cable. Some of the risers use molex connections (using SATA => molex adapter), some (moulded) SATA connections. Does this mean I'm also overloading these lines? O.o
Also: I'm European, so 230V here.

Grounds are connected through Add2PSU btw.

I would like to suggest one other possibility if you have a very manual procedure, use MSI AB and you are a tired solo operator.

It's possible on a fresh system reboot, if you use MSI AB to set the TDP and accidentally omit running MSI AB, when you run whatever mining software you are using, you are running your GPU's flat out.
Thank you for your comment.
I've had this in the past: forgot to lower tdp with ab. Luckily my PSUs detect overloading, and it shut off power.

In this case however, the system was shut down or in the process of shutting down, putting an enormous load on that one power cable to the mobo.
4  Alternate cryptocurrencies / Mining (Altcoins) / Re: My Asrock H110 Pro BTC+ caught fire on: March 15, 2018, 08:45:55 PM
This power indicated as "Extra power 3" must also be from PSU1.
Otherwise the connection is ok, I have this as well.
I think so too, but I have to be sure. I don't want to risk this anymore, it's scared me to see my equipment burn up and potentially burn down my house :s

Similar thing happened to me, but luckily I have seen the damage on my PSU cabal before it has started the fire. What went wrong for me was that, I put too many GPU's on one PSU. Because of that, there was too much stress on PSU's wires, which lead to damaging of wires. Maybe you have same problem. Maybe your PSU is not strong enough to support those 12 GPU's that you have.
I'm using 2x Corsair RM1000x PSUs of 1000W a piece. 6 GPUs are on PSU1, 6 on PSU2 Smiley

Hi guys,

Today it seems I fried my Asrock H110 Pro BTC+ mobo... Damage on the 12 connected GPUs I still have to assess Sad

The connector of one of the 3 power supply cables to the mobo caught fire. Luckily I had the reflex to pull the power cord from the socket the moment I saw the flames... You can see the damage in this picture. The connector and part of the power cable have melted and the mobo is scorched.

https://www.dropbox.com/s/44e5scw4gkqxfwv/Foto%2015-03-18%2019%2022%2020.jpg

Before replacing the mobo, I want to know what went wrong. I don't want to die in a fire because my rig acts up at night.

The wiring scheme:

https://www.dropbox.com/s/vv8s1lhvuuvcojh/rig%20sata-molex.png
The red line indicates the wire that caught fire.

What happened:
- I shut down my rig using remote desktop
- After a minute, I went to check if it was really shut down in the other room. I wasn't, it was on fire.

What I think happened: the mobo shut down PSU1, together with the connected GPUs to that PSU. However, somehow PSU2 failed to shut down, still powering the GPUs.
The GPUs tried to draw power from the mobo, which was only supplied by the one power line from PSU2 which got overloaded and caught fire.

Any thoughts on this?

Hi.

What is the default scan-time when you are mining from the daemon?
12 seconds.
Overridable in sldm with --scan-time switch.

Is it just my bad luck these last few days or is it a little harder now to find blocks after the upgrade?

Global hashrate has increase x2, x3 the last week. Makes it statistically 2x 3x harder to find a block Smiley

It's because the SLD chain is under attack right before the hardfork.
Things should get normal again after block 375000.

is it minable by an old laptop?
It is not.
SHA256 is an algorithm that is used by ASICs. (Even strong) CPU/GPUs cannot compete with ASICs.

The chain is not moving.
Stuck @ block 11


Target spacing is 60 minutes - so it's normal a block is only generated each hour Wink

Mined the blocks disappear !! what is the reason??
Probably the blocks you mined were not accepted by the network... happens if someone else mined the same block approximately the same time you did.

Two important pieces of information came out:
1. KYC mandatory for the NET -> NIMIQ conversion
2. Denomination: instead of 1 NET -> 0.1 NIMIQ it will be 1 NET -> 100 NIMIQ. Total supply will be 21 billion NIMIQ instead of 21 million.

Release of the mainnet is still pencilled in for Q1 2018. Before that, there will be another update to the testnet.
Anything concrete yet the conversion?
Also: I'm concerned about giving personal information and ID to a party I don't know and is not a well known well secured exchange.
Glad I didn't buy NET yet.

OP here. I went with the add2psu device, and been running flawlessly for over 2 months.
The device effectively copies power state (on/off/reset) from the main psu.

read the fucking rules of this forum.

asshole.
Do you have like a mental illness or something? Are you actually aware of the fact that you're constantly swearing?
I checked your last posts using the link on your profile: literally always swearing. Are you also like this in real life?

Found 2 blocks but they was not accepted:

Code:
Block found for difficulty: 2609757
Couldn't submit block: ac4d1e0efe4962cde13f01c48570b2abc4343092239eb6a4aa892b0d9
262ac70
Reason: Block not accepted - probably too late :(

Why???
Someone else found the same block the same time you did, but it got submitted to the network earlier. Unfortunate, but it happens Smiley
