I had about $60 worth of Steem on Steemit and must have written down the password wrong, I am still auto-signed in but I cant log in on any other PC or transfer the money without the password.

Not a massive loss but slightly annoying.

In case you're using Chrome try Manage Passwords from settings or ChromePass which reads all your "encrypted" passwords.

And I forked again...

Why?

Blockexplorer is just not working properly again, and must be resynched.



Currently at:
[2017-05-30 19:35:36] jackpot block 66064, diff 6.35, net 379.04 MH/s

Can someone confirm this?

I think I had a similar block height with the difficulty of ~11 which was suspicious, compared it to the block explorer and I was a couple hundred blocks AHEAD. It's getting pretty annoying that the block explorer is always the de facto correct fork everyone should follow. The longest or even just the most popular fork should be chosen as the one, not just some arbitrary, random non-mining node. Always going by and trusting a known, random node is a form of centralization.

Anyway, now I can't ven resync from scratch, stuck at block 37257 after several tries and half a day later:

ProcessBlock: ORPHAN BLOCK, prev=5b001f93d60b72e46747
>> nHeight = 37257, nPoWHeight = 19226
>> nHeight = 37257, nPoWHeight = 19226


This coin is just bloody awful.

Lost about 0.8BTC due to gambling last year , damn I feel dumb after that .. And I never go gambling again , probably greed already consuming me last year .. I'm so sad and depresses lol ,.. Maybe I'll go invest on some promising alts

(…)

After watching the free money drain down to nothing in 5 minutes, it makes me wonder how people can even get into gambling... at least the machines. If you're good at poker, blackjack, or have a lot of knowledge about sports or horse racing, that's different. A Milwaukee talk show guy named Mark Belling is into horses and posts his picks on the web.. he's gotten a few really big long odds winners in the last year which could have netted a person several thousand dollars on a 20 dollar bet. That's skill. Sitting at a slot machine, that's just flushing money down the toilet.

Poker, Horse racing and all that only works, because there are people who lose and people who win. If everybody was a pro, nobody would be able to do more than break even.

My biggest loss… well, counting possible future wins (apparently we do), I had 3100 Stratis, which I sold for around 0.4 BTC. It's around 7 BTC right now.

But looking at it like this is living in the rear view mirror. If I added all the trades which could have been better, I would be up like 1000% of what I'm actually up. That doesn't seem to be a good way to look at things.


Could have, should have, would have doesn't matter.



Now that would be 126 BTC today but I don't care. It's not just absolutely pointless to get stuck on what if's, that money at the time was very very valueable to me.

I think we should stick to realised trades and not what if's.

I think I saw someone manage to put 10 cpu on a system with that same PSU connecting all the cards.
Some where coming out of the case. But still they worked. Wink
Stabily? Well that is another story. Undecided

Would it be wise to split one VGA port and use it to power 2 cards?



Certainly not wise but you could contact them and buy some more 8+6 cables fairly cheaply. That's what I did.
But the problem is I do not have enough ports Cheesy

What would be the best idea for a 7th GPU?
Are you using 4xx or 5xx GPUs?

I basically just asked the same question regarding a 1200W PSU and have ordered a 1300W PSU but now it looks like it will be underpowered as well. One of the responses on my thread was to use two 750W PSUs joined. But I'm so iffy on doing that.
Yes I am using 5xx

I'm not familiar with AMD hardware so take my comments with a grain of salt, but:

Assuming you use RX 570's, each of them only require one 8 pin connector: 6x8 is a given and the rest can be plugged in with the likely provided 2x6 into 1x8 ping merging cables.

BUT, there's a reason why so many cables are on any give PSU.

Let's assume each 570 uses 170 watts based on a guru3d review, so it's 1190+70 watts for the rest of the PC is 1260 watts which means an 1300 watt PSU far from enough for 0-24 load.

And 580's are eating way more (8+6 ping). You either need fewer cards, a bigger PSU or multiple PSUs.
905  Alternate cryptocurrencies / Mining (Altcoins) / Re: Slow Hashing Rate Using Riser Cable [Nvidia] on: May 30, 2017, 10:38:08 PM
Hello all,

I have a couple of Nvidia G1080 cards and a MSI Z170 motherboard with 7 slots, and the hashing rate decrease significantly when I use a riser cable. When I plug the card directly in the PCI slot, then it hashes at full speed. Does anybody know of a solution?

What algo?

I mined over 40 algos on nvidia over the years and only one algo was slower on a riser due to 1x PCIE speed and I can't even remember which one was that so you likely have another issue.
906  Alternate cryptocurrencies / Altcoin Discussion / Re: Price vs Percent (which do you go for?) on: May 30, 2017, 10:33:52 PM
So, what do you go for in a coin say do you go instantly and buy a coin that is cheap (but shows volume and value of course) or you dont care about price and just go with whatever makes you more percent (hoping for)?

For example,

1. Buy $1,000 worth of SiaCoin at        0.00000353 BTC
2. Buy $1,000 worth of Etherium at      0.08974848 BTC

Why do you chose one over the other?

If that's your main deciding factor you might as well just flip a coin; price absolutely doesn't matter.

I know it is fully psychological, but I don't like investing in expensive coins.

For speculating, I like to earn %, so I like coins that are churning a lot.

For investing, I like a coin where I can own a large % of the market cap. For instance, if you own 1% of some crap coin and it hits a $billion dollar cap someday, then you own 1% of a $billion dollars.

Most of those crap coins that you can easily own 1% will likely end up in the shitter so what you're simply saying is that you prefer very high risk high reward coins.

That doesn't mean you can earn more with them long term than with a stable coin going 2x.

Pre-ICO a preliminary to ICO .  ICO gives you ideas for . It's good for bonuses to be higher .

ICO bonuses are scams in and of themselves.

It's basically telling "give me your money quick and I'll give you more coins I have just pulled out of thin air for free if you do".
908  Alternate cryptocurrencies / Altcoin Discussion / Re: Your biggest loss with cryptocurrencies? on: May 30, 2017, 10:25:39 PM
My biggest lost was definitely Josh Garza's fucking Paycoin scam. Second biggest was pbmining. Third is me being a dumbass and running random wallets on my main computer left and right without sandbox or VM and getting fucked by a malware years ago thinking it wouldn't happen to me.

Learned my lessons on all these fronts; not trusting anything remotely centralized (paycoin, cloud mining) ever since and always only run wallets in VM or in a restricted sandbox.

910  Alternate cryptocurrencies / Mining (Altcoins) / Re: Nvidia to release mining-only GPU? on: May 30, 2017, 10:12:20 PM
Here are my thoughts, some of which might be wrong;
 - display ports are cheap and easy to put on cards so it's kind of a pointless excercise to remove them;
 - virtually nobody is mining with stock nvidia cards; aftermarket cards is where it's at;
 - knowing nvidia, I can't imagine these cards not just costing less than their gaming counterparts, they'll very likely be more expensive for maybe slightly more cores but there's no way they'll be better in terms of price per performance. Every specialized (enterprise) cards are disgustingly overpriced;
 - nvidia not liking miners is just nonsense; GPUs owned by miners rarely ever get faulty, maybe only a couple of percentages more RMA than regular users but the increased number of sales should more than make up for it. (There's a reason as to the length of the warranty periods);
 - nvidia might have zero idea what features mining cards need, therefore they could be useless outside of a few coins (similarily to ASICs);
 - but if they do, what would be scary/awful is if nvidia would also provide their closed source miners.
 - these cards would have massively reduced resale value, just like ASICs.

I certainly don't hold my breath and kind of certain/hopeful that it will flop.

The single most beneficial thing of GPU mining is that virtually everyone has one which can be used for mining, eg. distribution of GPU-friendly PoW coins is great. Introducing a specialized hardware for miners would turn GPU mining into the same old  lifeless industrial world of ASICs with poor coin distribution since not everyone is going to have one of these.

912  Alternate cryptocurrencies / Mining (Altcoins) / Re: Poll: Mining Room Top Temps on: May 30, 2017, 12:57:23 PM
I just checked and my garage is 42.8°C/109.04F. Outside it's 29°C/84.2F in the shade.

Not much I can do for now.

Woah 109 degrees Fahrenheit!!!! That is running pretty hot. My mining room usually stays in the 78 to at most 89 degree range and I live in Florida. However, I do use a dedicated air conditioner to help keep the room cooler and if you use that option it adds maybe 25-30% to your energy costs for the rigs. 

Yeah, I can't pull more electricity now but I'm planning on moving soon with a better solution than what I have now. I don't like these temps either.
913  Alternate cryptocurrencies / Mining (Altcoins) / Re: Can anyone suggest cost effective UPS for minning rig on: May 30, 2017, 12:54:12 PM
A quick look suggests that it would cost you about $480 to get a UPS that can handle 500 watts for two hours: http://www.apc.com/us/en/tools/ups_selector/home/load.
But they're not designed to be frequently discharged. Recharging and mining at the same time after a power outage also increases your power consumption greatly until the batteries are full.

Also, there are two main types of UPS:
 - line interactive: it passes the power from the outlet through to your mining rig and only switches to the battery if there's a power outage. This is the cheaper/simpler solution and depending on your PSU in the mining rig the UPS might not switch to the battery quick enough so your rigs could restart. Unlikely, but possible especially with lower end computer PSUs.
 - online or double conversion: the UPS converts the input voltage to the battery voltage and converts it back again to 120/230V or whatever you can set it up to. This is more expensive, there's a few percentage of loss during the conversion (just like with a regular PSU) but it doesn't have to switch, it continously provides electricity. It also helps with bronwouts (when voltage is just low) but you don't need help with brownouts that since your computer PSU very likely can handle lower voltages but it's nice to have with other appliances.



I'd rather just setup the rig to continue where it left off after a power outage:
 - "Restore on AC/Power loss: Power on" in the BIOS so the computer turns on automatically as soon as it gets electricity;
 - put a shortcut of your miner (.bat) in start menu/programs/startup so that mining starts when the system boots.
 - don't run wallets on that computer as their blockchain will eventually corrupt and require a resync or restore if you have a backup.

https://etherscan.io/ether-mining-calculator

https://badmofo.github.io/zcash-mining-calculator/


Otherwise for one hour it's: your_hashrate / network_hashrate * 3600 / blocktime * coins_per_block

So for example Zec with 20000 sols it's:

20000 / 114250338 * 3600 / 150 * 10 = 0.004201 ZEC per hour.
917  Alternate cryptocurrencies / Mining (Altcoins) / Re: How to calculate coins per hour? on: May 29, 2017, 09:30:22 PM
Think the title explains it well enough, im trying to calculate coins per hour on ETH and ZEC but haven't found the formula for it, everything on google says use one of the tools, this is not my goal here.

Total coins per hour or your mined coins per hour?
918  Economy / Computer hardware / Re: WTS GPU server cases on: May 29, 2017, 06:12:03 PM
Hey, anyone who has similar cases can tell me what are the temperatures of the cards compared to the usual open rig with plenty of space between the cards?



I have bought around 10+ cases. Very good quality and nice cases indeed. Stackable. Smiley I use for cooling 6 x Scythe ultra kaze 120mm fans.

About temps:


MSI RX480 open rig:
 GPU0 t=68C fan=28%, GPU1 t=71C fan=30%, GPU2 t=72C fan=28%, GPU3 t=69C fan=30%, GPU4 t=72C fan=29%, GPU5 t=59C fan=29%

ASUS RX480 in case:
 GPU0 t=64C fan=37%, GPU1 t=63C fan=29%, GPU2 t=61C fan=29%, GPU3 t=64C fan=49%, GPU4 t=64C fan=39%, GPU5 t=64C fan=49%

Thank you. I put in an order a couple of days ago for two for starters. Can't wait.

how to trigger shutdown /f /t 5 if miner has problem, i don't want to restart the miner because sometime one card stop working and only restart the pc can solve it

Not sure but a card crashing that only a restart (or nvidiainspector.exe -restartdisplaydriver solves) is usually caused by too high overclock.
920  Alternate cryptocurrencies / Mining (Altcoins) / Re: Thinking for a trouble free build 6 GPU max on: May 29, 2017, 12:19:22 PM
These ones come to mind that can handle mining: Asus PRIME Z270-A, Biostar TB250/TA320/TA350-BTC.

Personally, I have ASRock H81 boards working fine so I'm sticking with them. It's nice to keep a farm uniform.
