Well some one just ran off with 32 million eth due to a weakness in a wallet type.

Ouch!^

Some issues...
Firstly, my CPU doesn't appear to be throttling properly. Even with the high performance power plan selected, sometimes it gets stuck at 1600MHz running CryptoNight. This cuts my hash rate by slightly more than half with that algorithm. At this time, C1E was already disabled in the BIOS.

Secondly, it seems my computer doesn't take two GTX1070s mining very well. All seemed good the first few days, but I woke up this morning to a black screen, which I had to hard reset from to restore normal operation. When I came home from work, it looked like my computer randomly rebooted. Power supply issue? It's a Corsair CX600w. 46A on the +12v rail for a total theoretical max of 552w +12v power... should be enough for 2 1070s, right? They're only rated to draw 150w each...

Bluescreenview tells me there was an x116 BSOD. dxgkrnl.sys crashed.

Pretty sure you're refering to the 7 million ICO heist. No wallet weakness that I am aware of. Otherwise, link please.

Anyone see about that McAffe guy thinks bitcoin is gonna be worth 500k in 3 years? Personally I think that's a bit on the high side.

I hope you don't mean Crazy Mcafee of anti-virus fame. He's nuts. There are very legitimate people predicting 50k by the end of 2020 though.

Finally got 3x580s I've had on preorder nearly a month and a half , it is quite tempting to put them on ebay but i quite like the look of these saphire pulses :).
I would sell them, they go for 1070 prices. Pick up some 1070s on auctions and snipe it at the last moment or find some cheap 1070s, I see some on ebay go for 400-420 sometimes.

Why would anyone care about him? It's just a random guy on the internet.

There is a positive probability for BTC to be worth anything in [0;+inf) in the future.
Done - now we're covered on the fortune-telling.
There are very legitimate people predicting 50k by the end of 2020 though.
You mean this guy Ronnie Moas? Legitimate? Oh come on...
The only argument he has is the limited supply of BTC, which is true, but irrelevant in the long run.

Strange issues over here. I had another BSOD last night apparently, so I turned my system off as I planned to reinstall Windows this morning. So, I go to my computer this morning and... nothing. It turns on, but black screen, and neither video card fan is spinning. Tried each card one at a time, nothing. Tried onboard graphics (not sure if it was ever actually enabled or not, I tried clearing CMOS, but it looks like CMOS never actually cleared), nothing. Tried my old 660 Ti... it boots. Tried one GTX1070, it boots. Tried both, it boots. Fired up Nicehash, crash to black screen in 5 seconds. Reboot, fire up Nicehash again, running fine so far.

I'm thinking power supply issue... but that doesn't explain why my computer wouldn't even start up this morning. It would explain crashes to me, but not why it wouldn't even start up. I did accidentally run the video memory at +600 for a moderate period of time (8 hours or so), but it ran fine that whole time and I've since reset it, as soon as I realized it was doing that.

Ugh, reinstalled Windows and now I'm seeing the miner (sometimes, not always) crash immediately upon startup. Fans locked at 100%, sometimes the desktop comes back, sometimes black screen.

You got SLI enabled while mining?

I was having some issues also but because SLI was enabled. Once I disabled it, all was good.

My gaming rig I left it enabled without issue, but I had one come into the shop with problems because it was enabled. Seems to be related to the driver loads from what I can tell.

Nooooooooo, never. I'm totally against multi gpu setups (at least SLI/Xfire, running multiple compute cards like this is fine by me).

To recap, some quick bullet points (and some updated information)

•Ran fine for a few days until issues arose
•Issues include BSOD, hard locked black screen, driver crash, PC not booting after shut down
•PC can fail to boot even with my old GTX660 Ti installed, no GTX1070 in system
•Already reinstalled Windows, issues persist
•GPU temps always under 80*c, usually hover at 70*c

So... leaning towards power supply issue, but I can't see how, when the system fails to boot (some fans come on but no signal, neither video card fan spins, same thing happened with my 660 Ti when I tried it, no signal, fans didn't spin), and I should have plenty of +12v power with this power supply for what I'm running. I know the CX600 isn't the greatest power supply, but it should handle two 1070s. I can't see how it could be a motherboard problem considering I've had this board for ages with no issue, or a problem with either 1070 when the system fails to boot with the old 660 Ti. o_O:nutkick:

I think you answered your own question hat. Youve had the system forever and you introduce a couple of cards and mine for coins.. think of it this way, the machine has many many hours on it and the added stress was just to much for it to take... Personally I think the mobo took a bad shit at the worst time possible for ya. Or the psu took a dump, it happens all the time.. but I'm leaning on the mobo.

You did say you re pasted them cards.. all went well?

It's 2017. Good quality graphic cards are almost noiseless and well within acceptable temp thresholds. Seriously, why take the risk of damaging the card while changing the TIM? :eek:
Also, I assume that this voids the warranty as well. There goes the mining profitability...

My issues also might have stemmed from having too many PCI-E lanes going on, was doing past 20 on this Z170. Once I ripped the last card out and disabled SLI I didn't have any drama's.

Changing thermal paste is acceptable by most manufacturers.
I know sapphire, and xfx will still respect their warranty. I had mailed them about it.

TBH the poor quality paste that they used to give, needed to be changed after 1.5 years.

If you are unsure, you can drop a mail to them.

Ronnie Moas wasn't even on my rader, really.

And aparently 500,000 is right if you ask some:

http://www.businessinsider.com/bitc...0-by-2030-first-snapchat-investor-says-2017-3
Again, this is built around the limited supply of BTC. And these guys aren't making a stock recommendation. They are SELLING you Bitcoin - they're both invested in the idea.

But most importantly: they estimate a market cap for BTC of 10 trillion USD (10^13) in 2030.
First, a quick reminder: M1 money is all cash and instantly available bank deposits (so what you can instantly pay with). This is the monetary aggregate which BTC mimics.
Just to show you how absurdly large this is: M1 aggregate for USD is ~3 trillion USD.
But it's get better. M1 money for the whole world is estimated at ~29 trillion USD.
So BTC would have to replace 1/3 of world's money (1/4 if you include 2% inflation).

And keep in mind a lot of M1 is locked in banks.

The scenario they're dreaming could be possible (but far from sure), if BTC was the only electronic payment method. It isn't and it's unlikely it will ever be.
It's way more probable that we'll get many new blockchains that'll compete with it.

Changing thermal paste is acceptable by most manufacturers.
I meant that damaging a card as a result of changing the compound will not be covered.
I don't think it'll void the warranty instantly, but I'm sure it's a lot harder to have a successful RMA afterwards.

E.g. flooding electronic equipment doesn't void the warranty as such, but next time you'll send it for repair/refund, they'll tell you that there are signs of water inside and you've used it inappropriately.

Yeah, I'm sure both 1070s are fine considering the system does the same with my old card. It's mobo or PSU and not sure which. Personally leaning on PSU myself... We'll see.

It sounds like the system tries to boot, loses power, tries to boot again, loses power... So on and so forth like that. I can tell by sounds made by HDD and optical drive. While this is going on, I can watch the PSU fan spin, stop, spin again... My case fan never spins.

Welp. I'm changing my vote to "catastrophic failure".





I'm guessing its motherboard and PSU replacement time. This begs the question, how did this happen in the first place? Was the power supply bad? Did the graphics cards draw too much power? Mobo or PSU at fault here?

What I'm not understanding is the graphics cards shouldn't really have been pulling much power from the board. They take 8 pin pcie connectors (which look completely undamaged by the way) which are rated for 150w, which is what these cards pull. If pcie provides 150w and the cards pull 150w, why is it pulling so much from the board?

Ah, was just a bit of a high resistance connection Hat, it would have been getting hot anyway and the extra bit of current pushed it too far. The cable side of the connector springs around the pin and if it's a bit loose or some dust gets on the pin it can cause a high resistance connection. They heat up which increases the resistance further which makes it get gotter... And so on until the connector melts and the connection breaks down. I bet other than the connectors that'd be fine.

If it's a modular psu you can get a new 24 pin cable and give the pins on the motherboard a close look, give the affected pins a scrape to get any crud off them, maybe use a paint brush with some isopropyl alcohol too.

Bet you it'll work again ;)

Shit, son. Your post saved me a lot of trouble. I just cleaned up as best as I could and put it back together and it works. But now, how do I not burn it up again? As I said before, I see no reason for it to burn up at all... the GTX1070s eat 150w each, but the 8 pin pci-e power connector provides exactly that, so they shouldn't be drawing much power from the board.

Some things I'd like to go over:
The board only takes a 4 pin CPU power connector, not an 8 pin. Is this just for the CPU, or does this power also go elsewhere? In other words, would a board with an 8 pin CPU power connector be more reliable when it comes to not burning up the 24 pin while mining?

My board has no additional power connectors. I've seen plenty in the past that had a spot to plug in an extra molex or even floppy power connector, but my board has nothing of the sort. Is this sort of thing a requirement for running multiple video cards?

I thought the whole idea behind building a mining computer was cheap board, cpu and ram, but badass video cards and power supply. How can two GTX1070s burn up a 24 pin when they only draw 150w and the power connector provides 150w, and others are stuffing computers to the gills with 4 or more cards?
