Fixed, thanks. Screen shot of bfgminer showed the correct hash rate.

Sold the rig to sandrig for 2 BTC.

Sold the broken blade and connector to broketech for 0.14

Will be opening a new thread for extra parts.

EDIT: Main rig (7x blades, backplane, PSU) is sold. Broken blade sold.  New auction for remaining parts to open soon (new post).




(Fan, ethernet switch, Raspberry Pi, RPi power adapter, Airport Express, power strip, and tables not included in auction but PM me for a price if you really want them.)

I'm selling because I've since expanded to higher speed/volume mining and these aren't high enough hash rate to be worth my trouble any more. They work fine, except as specified.

You may bid for one or more of the items listed below.  If you only want your bid to apply if you win all the items you bid for, say so, otherwise you may win some items but not others.

1. 7 ASICMINER v2 blades, running fine for the past month or so. Total hash rate on eligius is 71.05 GH as reported by bfgminer.

2. 1 ASICMINER blade backplane, used with above blades

3. 1 ASICMINER blade backplane, new in box and unused.

4. 1 HP server power supply, used to power above blades, includes 120 V power cord.

5. 2 HP server power supplies, unused brand new, no power cord included.

6. 1 apparently-fried ASICMINER blade (I think I plugged it in backwards to the backplane). It doesn't work but maybe you can change a fuse or otherwise fix it? Buyer assumes risk item is unrepairable.

7. 7 ASICMINER blade molex power adapters. I haven't used these because I'm using the backplane but if you want one or two blades they might be a better choice. Otherwise you might want to buy one for each blade to have for resale value.

8. 7 1' ethernet cables, useful for hooking up blades.

I will choose which bids I accept at close of auction (within a week, I will give warning when closing it). Bids for more of the items will get a slight preference at my discretion as it is less work for me. Cost of shipping and handling for priority mail is included with bids. USA only. Buyer assumes risk of lost or damaged shipments and may request insurance (again at buyer's expense).  Payment is in advance, escrow allowed at buyers expense subject to approval of escrow agent by seller.

EDIT: See post #2 for update on leading/winning bid.

EDIT 2: Everyone seems to want to include shipping in their bids so I'm now including basic priority mail shipping and handling at no extra charge. If you want different shipping and/or insurance that will be actual cost to be determined after the close of bidding.

I'm STILL (after 3+ weeks) missing about 0.5 BTC from a failed withdraw (database error). I've emailed support in english and chinese, PM to freeworm. Nothing.

Don't use this site if you value your money.

Can we get some kind of minimal NMC stats, like a list of payouts?

Good pools to use other than eligius (which seems to be down right now)? I've tried several others that give high rejects.

Down from here, using backup pool

I'm not criticizing the pricing or value at all (I have quite a few shares in multiple DZ group buys so I obviously think the value is there), just pointing out that these individually use much less power than industrial class machines like Jupiter or the upcoming Prospero X-3.

I'm seeing fluctuating power draw between 725 W and 730 W (not overclocked). This is at 120 V; at 240 V the power usage would likely be slightly lower.

They theoretically only use <400 W each (non-overclocked) which isn't anywhere near what the industrial class rigs use. Two of them together being one "rig" makes more sense. I have a Kill-a-Watt so I can get an exact measurement of my two Ant miners (which are on one 80+ Gold power supply) if that helps.

Same here.

The financial sector is roughly 10% of US GDP so 2% isn't automatically a "wasteful" number. It might be, depending on how much more efficient the rest of the financial sector becomes, or how much incremental wealth is created by people using bitcoin.

Also, the issue with 25 BTC/block is entirely temporary. When the block reward gets cut in half in ~2 years your 2% estimate instantly drops to 1% (and then 1/2% at the next reward drop). Of course that ignores transaction fees.

They apparently bumped the version of cgminer in their latest firmware.  I haven't tried with p2pool yet though.

I have 1600 MMC, will trade for BTC.

Terms: Slightly below bter market price (currently I would sell the lot for 0.0007, higher for smaller pieces). You send first, but we can break up the trade if that makes you more comfortable.

EDIT: sold

US has 0% duty on computer equipment so this is a non-issue. There might theoretically be an issue with state sales tax.

Is that 275/month per Antminer or 275/month for both?

I had bent frame on one of mine, but no damage to the board. I think the packing material is not adequate to protect these devices during shipping.

P2pool is doing fine. It's on the chart linked above, but it's too small. The problem with p2pool is that the interface is not really user friendly and it can be finicky to get working especially with certain miners. If you really want to help the pool concentration problem, volunteer to help with p2pool. That doesn't have to be coding, it can be better guides and cheat sheets, pretty stats sites, etc.

Arguably it is still a marketplace problem in that there may be lack of confidence that the pool is honest, will stay honest, and won't be compromised by (internal or external) dishonest actors.

The pool model is highly problematic and isn't solved by starting a new low-fee pool as someone else suggested because a new (presumably smaller) pool will have payout variance that is too high. There are some very nice smaller pools right now that don't even reliably solve one block per week. The incentive for the individual miner is always to sign up with the bigger pools to get consistent payouts, and that's bad for the system as a whole.

The way out of this trap is with p2pool (or build a new system like it if you don't like p2pool).

Not exactly "not legitimate" but the red flag for me would be that they don't even suggest a ship date. They say they will be collecting the other 70% of payment 8-10 weeks before shipment which tells me that shipment will be quite a bit longer than that (otherwise just collect the money now). That seems like a minimum of 4-6 months, best case with no further delays.

Given the current high profitability of mining with GPUs and the fact that they are still available (somewhat hard to find, but available) for immediate purchase I would expect scrypt difficulties to continue to rise at a high rate for the foreseeable future (absent a price crash). I don't really have a 4-6 month forecast though.
