It's a shit ICO with the worst names I have ever seen in crypto:

XtraBYtes
STaTiC - Services, Transactions and Trusted in Cointrol nodes
VITALS - Virtual Information Transmission ALigning STaTiCs
PULSE - Ping Unified LEdger Synchronization Equalizer


...
I fail to see how PoSign is any different from PoS.

It should be dead and burried, there's no point trying to sugarcoat shit, it's still shit.

And if the tech is really that good it should be forked/relaunched with a proper initial distribution, eg. not ICO.

I keep getting this error message randomly when mining on a couple of rigs:



at which point the card crashes and sometimes even the rig crashes.

I get this mostly on a 4 card 1080 Ti rig and a 4 card 1070 rig.

It mostly happens if I OC just a tiny bit (+20-40 Mhz) and if I set the power target close to 100% instead of the usual ~70%.

I'm suspecting it has to be the PSU but it doesn't make sense since they are EVGA SuperNOVA 1300W G2 in both rigs. And I have a rig with 6 x 1070 with the same PSU without any issues. I tried switching around the risers but didn't help.

You mean the Sata to molex cables?



If so, they're fine as long as:
 - you don't connect more than 2 GPUs to a single cable coming from the PSU;
 - you don't use cards that are very hungry on the PCI-E front. For example overclocked GTX 750 Ti without 6-pin or any card reflashed with a badly configured BIOS.

1. Sure, but I'd suggest getting some powered USB risers so that you can put the cards further (if you can) from each other so they don't boil each other.
2. I have no idea about that specific motherboard but it should be fine. With risers each card only uses 1x PCI-E lane, but even without risers you don't need SLI to mine, in fact you should always disable it when you're mining.
3. AFAIK that 1060 has a maximum of 120W consumption and most aftermarket 1070s have 180 watts. 120+180+180+140(CPU)+60(other parts) = 680 watts if you're pushing everything to the maximum which you're not going to do so you should be fine with a single 750 watt PSU.
4. Sure you can.

Yeah, bunch of coins are pumped by various pump groups I think.

With a decent power supply, no overvoltage and decent temperature limit (~70-75°C) it's probably at least 4-5 years I guess. The fans will give in in that time though in a dusty enironment.

It should come with 8 x PCI-E 6 + 2-pin cables as per the bottom of this page: http://www.thermaltake.com/This/Toughpower_Series_/Toughpower_Grand/C_00001718/Toughpower_Grand_1200W/Design.htm

If that PSU has only 2 cables for GPUs then it probably can't handle much more.

High capacity PSUS tend to have enough cables.

I usually just set the fan speed to 100% on the GPU I want to isolate and check myself.

ICO, cloudmining and hosting? Sounds like the trifecta of bullshit.

I wouldn't trust giving a bunc hof GPUs to someone to run them and not run off with them.

And even if you do find someone you can trust, it will probably cost a lot of money.

This just my experience/preference:

Poloniex: it's grown too big of an exchange, meaning that it makes or breaks coins. It's near impossible to get a coin listed on polo as they don't have time to bother with new coins being busy counting their money. Regardless, if you ignore all the FUD, recently more and more people have issues with polo in one way or another. They also somewhat strictly oblige by KYC/AML which means they require IDs even from people outside the US. I never, ever given even my real name to exchanges, let alone ID scans. Not because I have anything to hide, it's just I don't trust them and identification goes against crypto. Anyway, with fake name you can withdraw $2k per day per account. Ever since the first reports of polo users getting their accounts locked due to something along the lines of the source of their deposits seems malicious I'm avoiding that exchange as much as I can and only hold as much funds as I wouldn't mind losing that much. I mean I'm not condoning hacking or stealing but they're an exchange, they shouldn't play judge and jury based on where you deposited the funds from.

Bittrex: probably my favourite exchange, or was in the past but in the last few months it's getting worse. They used to have a Distribution tab showing the top holders for each coin but they silently removed that feature for some reason. They also removed Joincoin with an announcement that they will do that at a set date instead of a warning that they expect more trading volume (therefore more profit from fees). So there was nothing to do by the community so they pretty much killed Joincoin. When I pay with bitcoin for goods and services I usually do so straight from Bittrex but recently the authorized withdrawals are taking long while it was used to be instant. They're also planning on changing their UI to a pretty terrible one if you ask me.

Kraken: I have zero experience with it.

Since I got into it I'll add a few more:

C-cex: not that big of an exchange but they're pretty great I think. At least I never had any issues with them. I especially love their UI, compact, to the point information.

Yobit: alias Aw, Snap Chrome ran out of memory while trying to display this webpage - because they don't put their site to sleep when it's in the background so whatever page you're on inside of yobit it still refreshes all the rapid bot activity of all the coins on the side until it crashes that tab in a hours, maybe days. Massively bot infested mass-shitcoin collecting exchange but it's a great medium size exchange with some crazy surprise pumps.

cryptopia.co.nz, coinexchange.io, empoex.com, coinsmarkets.com, novaexchange.com: the smallest of fishes I can barely differentiate.

Likewise. I don't have any cases yet only open rigs so I'm just writing what I've read and what I assume and your tests are informative.

Can't wait for my cases to arrive so that I can also experiment!

It's not the blocktime.

I've been told the forks were caused by coin-server (which hosts a lot of masternodes) going down.

Apparently every time a significant amout of masternodes go offline at the same time a fork could happen due to the masternode payment enforcement.


This is a serious problem I think.

Sure, people shouldn't use centralized masternode hosting services but realistically, people won't move their masternodes to other more reliable but more expensive hosts.

Something should be done to make sure the network is unaffected if/when a lot of masternodes go offline simultaneously. Otherwise the network can be attacked any time.


I might be wrong though but what's clear that it's a bad timing to have forking issues.

Gigabyte GTX 1070 G1 Gaming (GV-N1070G1 GAMING-8GD)
Gigabyte GTX 970 OC (GV-N970WF3OC-4GD)
Gigabyte GTX 970 mini (GV-N970IXOC-4GD)
Gigabyte GTX 750 Ti Windforce OC (GV-N75TOC-2GI)
Gigabyte GTX 780 Ti (GV-N78TOC-3GD)

These are the cards I had and ALL have crappy sleeve bearings. And they got progressively worse (except for the 780 Ti) with each iteration until AORUS came along with its superb fan design.

You can tell if a GPU has crappy sleeve bearing fans by: just touching/moving them and they feel like a plastic toy from a Kinder Surprise, seeing the product pages (ball bearings are always a heavily advertised feature) or by just watching them spin slower and slower after months.

Edit:
GeForce® GTX 1070 Xtreme Gaming 8G (rev. 1.0) - GV-N1070XTREME-8GD
GeForce® GTX 1070 Xtreme Gaming 8G (rev. 2.0) - GV-N1070XTREME-8GD
AORUS GeForce® GTX 1070 8G - GV-N1070AORUS-8GD

Only these 3-fan Gigabyte 1070s have double ball bearing, every other one has sleeve bearing.

I just forked again...

The wallet was working fine for weeks until these last couple of days.

These cards are amazing at cooling but they're not designed to have airflow going parallel to them:



These cards want air from where you would normally put another GPU in case of mining and as you can see the direction of the heatsink blades and the plastic cover, pushing air to them lengthwise from either direction is pointless.

In a typical gaming computer with one card there's plenty of space to pull air from.

Let's look at this typical 4U server case setup sketch:


Orange = GPU
Green = air direction the cards are desidned
Red = case fan air direction

As you can see if anything, the case fans might even work against the GPU fans. And the output of the hot air on the top and bottom is also blocked in a closed case which makes it even worse.


And they're also very wide cards (5,5 cm) so in a typical 445cm 4U case there will be only 1,43cm between cards and the walls in case of 6 cards. And that 1,43cm is where they're trying to pull air from.


I have a couple of these cards in an open rig with about 6-8cm in beween them and they're the coolest. I'm also trying to move away from open cases to server cases because of dust but I'll be leaving these cards in open frame rigs because these cards - unlike its predecessors - have double ball bearing fans so dust is not as much of an issue. If you dedust them frequently of course with an air compressor. I have Gigabyte GTX 1070s with already replaced fans because they're so poor quality even low quantites of dust kills thems, meanwhile I still have 970s of the same design with more or less working fans.

@strasboug

Turns out I didn't have staking disabled (typo) which is why I kept forking but now it's fine.

Is there a plan to remove staking with a fork (until it's stable on testnet) and reenabling sweepstakes?

In case of a single rail setup if the PSU can't deliver as much as you're trying to pull it will just shut down and not burn anything so it has to be something else.

How is that possible to plug them in backwards?
