Test, 1, 2, 3, test! Is this raffle still on?
Seems you lost steam...

Looks like 56 tickets have been sold now.

So I've seen advertising for this raffle but no more ticket sales. Cablepair, what is you plan to finish out this raffle with no sales made in the last 3 days?

Is there is safe and well known service that offers a very safe and storage for btc? Like a vault? 

Thanks.

- Buy a used laptop.
- Reformat the drive and install ubuntu.
- Install the bitcoin client and download the block chain.
- Create an address in the client and write it down.
- Send BTC to the address to test everything.
- Close the bitcoin client and shut down the computer.
- Take the computer to the bank and put it in a safety deposit box.

This is what I would consider very safe storage for btc in a vault.

p_shep - thanks for the Rev3 pics!

gigavps - are the Rev 3 (assuming Rev4 is a typo) running any cooler?  Can't tell what is what on the mgpumon display...

lol. I have no idea which is which either! I was told by BFL that the temps displayed can vary quite a bit. The most important thing is for the singles to not start flashing their front LED at the ambient temp while mining.
1944  Economy / Securities / Re: [GLBSE] Bitbond 20Gh/s - the only 110% PPS mining bond on: April 14, 2012, 08:54:33 PM
Well, if you say you are backing this bond with 20 GH/s, it might be even a bad business decision instead of just marketing talk - imagine a 1000% PPS deal for 1 GH/s backed by 100MH/s for example... Wink

Amazingrando is one of the very few miners to be able to offer a deal like this at scale. If he needed to throw 40Gh behind this venture to make it successful, he could easily do it without batting an eye.

As for what to call his offer, 110% may not mean much if you only own 10 bonds, but for the larger investors who have put their faith and BTC into his offering, it is a bonus OVER what they were expecting. Amazingrando is under promising and over delivering for the investors who believed in him.

Just imagine what this community would be like if everyone tried to do this.

Agreed Grinder, not a single one of 15 my cards running at 0,95V can do above 740 24/7 stable so it would either have to be one crazy bin or the card simply isn't running at that voltage.

I now have 10 cards running 850/150/.959v! Two are running 825/150/.959v.

http://gigamining.com/mgpumon/

See rigs 100, 107 and 110. The 110 rigs has 5k shares on each card.

I think the .959v over .95v makes a big difference.

Hi Zubilica,

I just worked through this issue with my 17 device rig. Follow the instructions below to fix it. I'm sure lodcrappo will have a patch for us soon.

  • run the command: nano /opt/bamt/mgpumon
  • press the keys: ctrl+w
  • type: 4000
  • press enter
  • change the value 4000 to 8000
  • press the keys: ctrl+x and then y (this will leave the editor and save)
  • back at the command line run: killall mpgumon
  • then run: mgpumon /etc/bamt/mgpumon.conf &

This will fix your issue.

Well this is interesting. I have two 5870s on miner100. I set them to run at 800/150/.959v but for some reason they are running at 850 core!

http://gigamining.com/mgpumon/

Anyone know why that would happen? Or better yet, I'm wondering if I can run all my 5870s at 850/150/.959v.   Shocked
1948  Bitcoin / Hardware / Re: FPGA Rig Photos on: April 13, 2012, 09:44:04 PM
11 x Rev.2 and (in the back) 4 x Rev. 3, if I count correctly?

The count is:

Rev1 == 4
Rev2 == 7
Rev3 == 4

The ones closets to the PC are Rev1s. They're taller than Rev2 because they use just the big heatsinks on the bottom.

It's that time again. Moved some things around a bit.

1951  Economy / Services / Re: Gigamining / Teramining on: April 13, 2012, 06:28:57 PM
It does make sense in a way.....thanks for taking the time to respond.  If nothing else, it is highly creative and allows you to retain ownership of all equity. 

I wish you luck on the mini-rigs.....I am skeptical that they can hit those specs given their records on the singles.  It will be very interesting to watch the timeline. 

The bond makes sense for all involved. A win/win if you will. The idea of the perpetual bond is not mine, Meni deserves credit for it. I only took it to scale.

I have been in contact with BFL for months. They are an excellent team and I have been impressed with their efforts thus far. I would not have put this bond together if I did not believe they could deliver. I can understand how you might be skeptical by reading others uninformed opinions.

Hopefully we can keep this thread on topic now.

Thanks,

Giga,

I have been following this thread with a lot of interest.  I am curious what you hope to accomplish with the bond? 

If you are paying out 100% of the PPS earnings on your 50 GH/s, aren't you eating the power cost?  How about inevitable replacement needs?  The time you spend keeping everything running smoothly?  Is this a one time cash-out by you in order to monetize your (extensive) effort?

Perhaps you are just a benevolent benefactor for the entire community?? 

Hi yochdog,

As was pointed out in my feedback thread, the 50Gh bond will be run by two Butterfly Labs mini rigs. I bought them at the early bird price of $12.5k each. Each BFL mini rig is spec'd to pull 1250w to generate 25Gh in mining power. With my electricity costs at $0.07104 and assuming 745 hours in a month, the electricity will cost ~$135 per month. I am willing to pay out 100% PPS because I run all my equipment on GPUMAX and have confidence that the service is only going to get better with time.

There are other risk factors involved in running a bond like this which you have pointed out. Since all of the costs the mini rigs add will be incremental costs (aka I already have a working farm and have already purchased the mini rigs) the barriers for me to do this are pretty low.

My ultimate goal was to create more working capital while offloading some of the risk of running the equipment. This has been accomplished and my first priority is to make sure bond holders are justly rewarded.

Hope this helps.

Best,
gigavps

I saw in your contract:

Quote
Percent of majority  
to change contract:   1
for general motion:   1
to issue shares:      1
What is this mean? Anyone, who has 1% of total shares can do anything?
Or only you have ability to make a proposal to a vote?
If yes, then, you (with only 1% of shares) can do what you want?
Or I missed something? Please, explain how this works.

Hi rastapool,

This is an issue with the glbse interface. I have offered and sold a "bond" not shares in the company. A bond has not voting right, cannot change the contract in any way and there is no need for motions.

Best,

1954  Other / CPU/GPU Bitcoin mining hardware / Re: Undervolting a 5870 at 0.95v on: April 13, 2012, 10:31:43 AM
I have 2 under-volted 5870's.

One at 840/155 and 1v = 384 mh/s
The other at 755/155 and .95v = 347 mh/s

If I try to set the first card to .95v I have to set the engine clock too low to around 400, otherwise it crashes.
The 2nd card is happy as can be at .95v

That's a 5% drop in power usage and 10% drop in hash rate, not very attractive IMO

But of course if you have plenty of hash power and want to reduce the noise/heat, it will help

All my 5870's are set at 1.000v and 825/150 clocks.  So each rig (5 cards) gets about 1850Mh/s @ 650W.

Do you mind running a rig at 800/150/.959v as seeing what kind of power draw your are getting?
1955  Bitcoin / Mining / Re: [105% TESTING] I want your hashing power! "Project #2" on: April 13, 2012, 10:24:00 AM
The BFL singles do better than GPUs... Why I do not know. 1% or less is what we want over time but 2% or less is very reasonable.

When it this thing kicking into high gear?
1956  Bitcoin / Pools / Re: [551GH] ABCPool PPS - Proxy Pool For High & Steady Mining Rewards on: April 13, 2012, 10:23:18 AM
i think if ABCpool implement merge mining for namecoin mining would be better

because almost all other pool has merge mining feature !

You are missing one small fact.......

ABCPOOL sends your hashes to other pools.

They are already making nmc from other pools like ozco.in. They just don't pass them on to their users.
1957  Other / CPU/GPU Bitcoin mining hardware / Re: Motherboards: What Works w/Four or More GPUs? List Them on: April 13, 2012, 10:21:09 AM
I have the same board, and it does work with 4 GPUs.  I am actually running 5 on one right now.  (same CPU too)

BUT, the last two I have bought have a bunk PCIe x16 slot!  Both of the last two I bought had a bad PCIE4 slot, that is the middle x16 slot.  I have a third coming from NewEgg right now...  I hope it works, because I like this board otherwise!

I've had a couple of the asrock 970 boards come a little flaky. I just bought 20 of them so I had extras when I was building out my rigs.

They also sell these boards at amazon. If you have prime, you can same of the shipping charges.

http://www.amazon.com/ASRock-MB-970EX4-970-CrossFireX-Motherboard/dp/B0058HUQJ0

If you only need 4 PCIe slots on a board, you could also check this one out as it is $30 cheaper.

To all gigaminers,

I have updated the gigamining home page with the amount of the first coupon payment. There is an extra bonus that will be paid out every time the difficulty changes. Since I don't want to spend too much time on calculating coupon payments every week, the day of the difficulty change will go to the lowest difficulty.

You can see the first coupon payment amount here -> http://gigamining.com/

You will also notice that there are only 5k bonds being paid coupons. I have struck a deal with a large bond holder to hold back receipt of the bonds for a couple weeks which will help with coupon payments until the mini rigs arrive in 4-6 weeks (yes, that is both a joke and the actual time frame).

I have also bought back the remainder of a mining contract I sold for 10Gh to make sure enough bitcoins are being produced to make coupon payments. On top of this, my glbse.com account will always hold, at a minimum, two weeks of coupon payments.

Why am I telling you all this? I want to be as transparent as possible so that you can have confidence in me and this bond.

Best,
gigavps

Hey gigavps,   what kind of savings do you get from the rig going from same clocks at stock to the new .95V?  Is there a substantial wattage savings?

I am thinking of starting to undervolt my rigs as electricity is killer but stability is real concern.  Smiley

Not sure to be honest. I don't have a kilawatt that works on 208v. My main concern with undervolting is better stability and longevity of the cards. Also seeing a decrease in my power bill is nice.
