To the public / openly or just 'selling'?

Anyone just selling. Would like to get some chips to evaluate developing custom PCB and cooling.


Probably if you got the cash to make them deal with you.

ASICMiner, Avalon, Bitfury, Bitmain, Spondoolies, and if your daring KNC

Not cash heavy at the moment but can buy sample chips to evaluate some PCB designs

Do you ship to italy?

I will ship anywhere once the buyer is willing to pay for it. Shipping will be from the US.

Are you interested ?

Yes, i'm interested in 2-3 pieces if you can lower the price to 70-80 usd/pcs. Too low or still feasible?

Too low. Can get it sold for $85 right now from a previous offer without the hassle of international shipping.

332  Bitcoin / Development & Technical Discussion / Re: Parallel computing in Bitcoin on: February 13, 2015, 09:56:19 PM
Parallel computers are often used to analyze complex systems in supercomputers. It seems that blockchain analysis has similar complexity that would benefit from supercomputers. They could be used to track outputs for metacoins and optimize wallets to minimize transaction size. If SHA256 ASIC coprocessors were added to a conventional parallel computer, it could be optimized for blockchain analysis.

The ASICs on the market are already optimized and parallelized.

I have a 500 core (Xeon E2600 v2) compute cluster machine at my university.

If I had that at full power for a month, I reckon I'd mine a few cent.

OP is not talking about using hpc [clusters]/super computers to mine BTC. He is talking about using hpc [clusters]/super computers to do analysis on the  data  in the blockchain.

That is my understanding. OP can correct me if I am wrong.

335  Economy / Computer hardware / [SOLD] 1X PowerColor Radeon HD 7950 Boost State on: February 04, 2015, 12:48:56 PM
Hi Guys


Would like to sell PowerColor Radeon HD 7950 Boost State cards for $150  $85 each. These are solid cards that have not been used to mine for more than about 2 - 3 weeks last year before shutting down.

They are available  refurbished from NewEgg for $229 . See the link http://www.newegg.com/Product/Product.aspx?Item=N82E16814131540&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Desktop+Graphics+Cards-_-N82E16814131540&gclid=CjwKEAiAo8emBRCX_OqU4qek6y8SJACzgf8fDRmxRVd9Y4VLEBFU4Vo7T_rcc7aAYLurQ8p5zfTXdhoCWbnw_wcB&gclsrc=aw.ds

I am only asking for $150  $85  USD each.

338  Bitcoin / Hardware / Re: Cointerra AIRE Miner 16nm PreOrder on: January 27, 2015, 07:11:09 PM
The good thing is none of this matters any more since Cointerra filed for bankruptcy   http://www.coindesk.com/bitcoin-mining-firm-cointerra-files-chapter-7-bankruptcy/


The preorder was obviously an attempt to try to save themselves. Guess the community choose to spend their money else where . Hopefully all manufactures that have screwed and continue to screw over their customers have a similar fate [KNC]
339  Economy / Computer hardware / Re: WTB/WTT Any Nvidia GTX 760 or greater series on: January 27, 2015, 03:18:00 AM
Any interest in watercooled cards? Have an Nvidia Hydrocopper 780.
Would i have to do any kind of maintenance besides plug and play ?  If it runs smoothly no problem. 

The cards i have for trade are basically brand new SAPPHIRE DUAL-X  280X http://www.newegg.com/Product/Product.aspx?Item=N82E16814202088

PM me the details if your interested in trade or sale.
