Re: THIS IS AN ISSUE: Bitcoin mining network uses a min. of 257 Megawatts per hour.
It will be nice to see a comparison - something like this:
Cost of running bitcoin network VS sum of all bank transfers fees on annual bases around the world

Cool, thanks. How stable are they? Do they need to be babysat?
More likely in the 3.5TH range, with overclocking. Unless you live in the arctic, the Bonus Neps like to overheat/shutdown due to KnC not including thermal pads. You'll want to install good heatsinks, or upgrade the fans, or both, depending on how much you want to spend. (listed in order of cheapest to pricey) Once you get them running, they tend to stay running fairly well. They can lock up every once in a while though.Cool, thanks. Has anyone sourced replacement thermal pads? Fucking KNC.
The pads are 5mm thick I believe. Just search on ebay - there are a couple different brands available. Get the ones with the best w/mk thermal conductivity. The other option is to get some 5mm tall heatsinks and mount them onto the vrms. Here is an example: http://www.ebay.co.uk/itm/8x-Pure-Copper-Memory-Chipset-Cooler-HeatSink-Heat-Sink-For-IC-DDR-RAM-VGA-SDRAM-/171317955844?pt=LH_DefaultDomain_3&hash=item27e3588d04
Hope this helps.
Re: [ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs
I have around 9 Corsairs AX1200i . That is the best PSU I have seen and used by far. Although recently I started to use IBM BladeCenter DPS-2000BB server PSU. I am modding them myself with 4 6 pin pci-e connectors and using each of those to power one sp20. They are a single raid 91+ gold psus and are relatively cheap compared to the ATX ones.
Hmm, strange ... I have 2 rigs with 970s - one with 6 cards and one with 5 cards. They both seem to find block on a regular bases without any rejected issues. Driver is 344.75
Its from the Miner Operator software that BA provides on their website:
http://www.blackarrowsoftware.com/store/download.html
You run it on a PC that is on the same subnet as the miners. It will automatically scan the network and it'll find the devices, from there you can choose from the dropdown menu in the bottom right corner of the software different options for the devices.

Well that's new! Have you done any tests with lower voltages? That could really help people out if the efficiency can be improved.
I haven't tbh, but when I upped the voltage from 0.81 to 0.85 I noticed a significant drop in the errors count on all 4 machines. Also there are quite a bit options offering different voltages all the way down to 0.5v. The max is 0.9v
Its in the Miner Control Software. Will post a screenshot later today if you still cannot find it. Cheers.
I'd like to see it. I don't have access to the software.

Cheers!
The voltage can be adjusted with blackarrow's software. Just tried that on my X3 miners and it works like a charm.
Never seen that setting. Got a screenshot?

Could you have underclocked it more? How is the noise level at those settings? I can't find a proper review of these anywhere...
They don't adjust voltage, so they're 1 J/GH at all clockspeeds. Noise-wise they're quite loud.

The mass changing of the addresses, combined with no lockdown on the accounts point towards a direct database injection (also known as SQL Injection). Chris mentioned that he will be doing some migrating on the website, that of course includes databases migrating. I highly doubt this was malicious database injection and most likely the actuall reason is an error during the migration or some wrong command executed.

The payment was in LTC - yes. I'm not comfortable in sharing amounts ... etc.
Would you mind sharing/posting the transaction ID? please
Sure, here you go:

fully paid by now (except for ref payments, no idea when that is supposed to come through..)
(except for ref payments, no idea when that is supposed to come through..)Usually - monday.
Re: LTCgear.com, the best scrypt/scrypt n/X11 cloud mining service, ROI 2 months
You received just a fraction maybe because the payment was till 10th of Dec. You can see that in your account - (Dec 4 - Dec 10) referrals payout . Anything past that date is still to be paid.
Re: LTCgear.com, the best scrypt/scrypt n/X11 cloud mining service, ROI 2 months
I'm still waiting for my payout, I'm upset about this and Chris' "news" are no relief.
Now it's my fault as my account is suspicious, or what? I didn't change my
payout address or payout method for many weeks, but now I'm told the delays are
basically my own fault because I made "last hour address changes".
True, ltcgear provides a good ROI opportunity, but what is going on here is
customer deterrence instead of customer service. If (and I say if) I'll eventually get
any of my payout, I will certainly think twice if I'll reinvest here or not.

I completely understand you. However, no1 said it is you that did some last minute changes to your account or you made it look suspicious. There are a lot of ppl confirming that they payout addresses were changed somehow, so accounts with such issues were audited manually. Accounts with many login attemps from different IP addresses are being investigated manually aswell. Chris is implementing a mail confirmations upon changing addresses in the accounts. The update will be live soon.

This is relevant aswell:
"Hi,
There are still some payments waiting to be verified and sent.
" share payout while BTC was indicated?" - as I explained earlier, there was suspicion about minute changes before payout, so parameters like address and coinchoice were extracted from backups. If payout was executed in shares, it probably means the user chosen shares then he may have changed his minds and changed to BTC.
What else is left missing (which is narrowed to percents of customer base) - it was really suspicious and requires address setup under new policy / address change mode."
