1  Economy / Computer hardware / Re: [WTS]2.5Mhash/s Mining Rigs/ R9 290s on: March 30, 2014, 12:25:51 PM
Sorry guys, these rigs have all been sold locally for close to the offer price.  I do have 1 left, however it's not likely to last long.  If anyone is still interested, more than happy to put a picture up here with my forum name.

FYI, these probably won't be cheap to ship out of Australia, so shipping to Australia is preferred.

For the past 8 hours LeaseRig has been reporting just under 28Mh/s, which is just about right: https://i.imgur.com/oo95QlE.png

My own internal monitoring is showing us sitting just above 28Mh/s.

Keep in mind per my post earlier, I did update the LeaseRig proxy part way through your lease which means the more recent results are more accurate.

NOTE: I'm using the LeaseRig proxy for my rigs.  From time to time the LeaseRig proxy reports significantly less than the advertised hash rate when mining low difficulty coins.  Please check your pool for the actual hashrate if you notice this occurring, my rigs are most likely mining at the correct hashrate, it's just the LeaseRig application reporting back incorrectly.  Any questions, shoot me a PM Smiley

Just out of interest what are you running for 28MH?

Just about to rent Tongue

Renting for the past hour and it hasn't topped 23mh?

asicbeast01 (28mh/s) is running:

11 rigs, each running 3 x 290Xs = 28.05 Mh/s
1 rig, running 1 x 7950, 1 x 7970 = 0.9 Mh/s
Total: 28.95 Mh/s

This should easily hit the 28Mh/s mark, however I've seen it report much lower when using low difficulty coins.  I think this may be the way the LeaseRig proxy is reporting back to LeaseRig.  I've just asked LeaseRig to take a look at this, and let me know why this happens Smiley

FYI, asicbeast02 is actually running ASICs.  50 x GridSeed miners.  Originally asicbeast01 was running them, but had to do some reshuffling so if you want asic based miners then check out asicbeast02.

Let me know if you have any other questions!

And you may want to manually add my pools as below. I simply cannot add pools to your rig

stratum+tcp://pool-eu.hash.so:1337/
stratum+tcp://pool-us.hash.so:1337/

username = laudney.1
password = x

I sent you a PM to refund you for the time when you weren't up and running on your pools.  Strange you couldn't update, I'm using the leaserig proxy - so completely controlled by leaserig in terms of how it works.

Thanks!

Is it just me, or are others noticing a decent amount of dust inside the miners?
8  Economy / Computer hardware / Re: [WTS] ATX PSU to 2.5 or 2.1/5.5mm 12V coaxial plug power cables [New Product!!] on: March 04, 2014, 11:41:03 AM
My preference is 15-18 leads per PCI-E cable, and scrypt only.  I would not run these in dual mode.  Having an inline fuse would be useful in case of mistakenly enabling dual mining mode.

As for length, I'd go up to 1 meter for flexibility. With a single cable going from 20cm and scaling up in groups of 2s or 4s to 100cm.

I'm ready to purchase enough for 50 miners right away, and likely for another 100+ miners in the near future.

seerhaad, this should have been fixed some time ago and missed hours have been added to your order.

2. Can you tell me how you wired this up?

If using a stand alone PSU, on the 20/24 pin connector:
1) Optional: Put a high wattage resistor across a red (5 volts)and black (ground) wire. Pins 23 and 3 work well. This puts a 5 volt load and stabilizes the 12 volt rail.
2) Short pin 16 (green: power on signal) to a black wire (pin 19 works well). This turns the PSU on.

For all PSUs:
3) Take a drive connector. The yellow wire is 12 volts, and the black wire is ground. On the miner power cable, the Red Miner Wire connects to Yellow PSU wire, and the White Miner wire connects to the Black PSU wire.

Although the Drive wire connector is rated for 11 amps (130 watts), I wouldn't put more than 4 amps (50 watts) on a single wire. Although that would be all 10 miners in LTC only mode, to be safe, I wouldn't put more than 2 miners per Drive wire.
[/quote]

I'm thinking of using a standard PC power supply to power the miners.

What is your reasoning behind only putting 2 miners per drive wire?  From my understanding 130 watts should support at least 15 miners.

Can the PCI-E cables be used at all?
11  Economy / Service Discussion / Re: Support a Bailout for (MT)Gox.com on: February 26, 2014, 07:29:27 AM
Mt Gox needs to go down, they were poorly run from the beginning and they shouldn't be in business.  If they are bailed out people will still have lost faith in them.

On top of that, I don't think anyone in their right mind would bail them out - considering that most people will leave and stop using Mt Gox once they have been bailed out.

Mt Gox is bad for bitcoin, and they must fail - so much of the price fluctuations has occurred due to them.
12  Economy / Service Discussion / Re: How many BTC's did you have stored at MtGox? on: February 26, 2014, 07:21:53 AM
0 BTC, after having some stuck in there for a month just to get verified I quickly realised this wasn't the place to be storing my bitcoins.
13  Bitcoin / Hardware / Re: LightningAsic usb miners based Gridseed GC3355 Tech Support Thread on: February 26, 2014, 04:29:52 AM
Can anyone confirm they've removed the fans on these things, and they don't run too hot in LTC mode?  Please confirm your ambient temp, and if you use any other kind of cooling.

Thanks!

With some help I managed to get into the controller, and get ssh working. It is indeed off by default.

However, I instinctively changed the root password as soon as I got in, so I can't really help with the password hash Tongue

I uploaded the binaries of cgminer/minerd from the /www/soft directory here: https://drive.google.com/file/d/0B7cOfhzHSYKJWWVOTF9uN0RxcHc/edit?usp=sharing maybe somebody can use those (I don't).

This is the /lib/modules dir: https://drive.google.com/file/d/0B7cOfhzHSYKJeGh3YUxfOHpjWDQ/edit?usp=sharing

Please let us know how you got in Smiley

Also, if you have any steps/scripts you used to get cgminer up and running that would be huge help as well.  I'd rather run cgminer if I could, but don't know any of the details on getting them running on the controller.
15  Bitcoin / Hardware / Re: LightningAsic usb miners based Gridseed GC3355 Tech Support Thread on: February 24, 2014, 10:39:46 PM
Does anyone know of a way to setup a backup pool in the controller (this is a non-LighteningASIC version, I'm waiting on an order from asiabtc now)?

Right now I can only setup a single pool, which means no backup.
16  Alternate cryptocurrencies / Marketplace (Altcoins) / Scrypt Hashing Mining Contracts on: February 24, 2014, 12:37:01 PM
I have a mining farm available for rent, at this stage I have 11 rigs running at 2.5Mh/s, and bringing on a few more rigs over the next week or so running at 3.3Mh/s.

At this stage I'm testing out interest, and will make more rigs available over time:

Rigs:

as01 3.3Mh/s - Available

Price: 0.0199 BTC/1 Mh/24 hours

Rental Periods Available:

3 days
7 days - 5% discount
14 days - 10% discount

If you are interested, please contact me via PM with your preferred rental period.

My reputation thread can be found here: https://bitcointalk.org/index.php?topic=434032

At a later stage I'll make 30-50Mh/s available via a single lease for those who are interested.
17  Bitcoin / Hardware / Re: Gridseed Tech Support Thread on: February 22, 2014, 03:53:53 AM
Also, does anyone know if it is possible to run 10 miners in LTC mode off a single power supply?  Or more, say 20 or 40?

I'm thinking of doing something to others in this thread, use a 4U case and remove the fans.  Run 20+ miners, and use some fans at the front/rear of the case.
18  Bitcoin / Hardware / Re: Gridseed Tech Support Thread on: February 22, 2014, 03:52:39 AM
Can anyone figure out how to get into the controller?  Is it possible to hook up via USB to the computer and access the filesystem somehow?

A few questions if anyone can answer:

Are the packages from Jack meant to include everything to get up and running?  Including USB hub, etc?

Is there a flash update for the controller?  If yes, how is it installed?  In the same way the miners work?

Anyone?
