Topic: [WTB] FPGA Miners (Read 1323 times)

Upgrade to ASIC, folks!  The price of bitcoin is out of control - If you're still mining FPGA, please consider selling them off to me.  You can instantly buy even more hashpower in ASIC and save yourself quite a bit in electricity cost, heat, and overall hassle.  Bad fans?  No problem, I have a ton of fans in the post right now.

I just got a great lead on another interesting (non-mining) FPGA endeavor, and would like to scale to at least 100G of equivalent hashrate in FPGAs.  That means I need at least two more sizable rigs, so if you have one and are interested in upgrading let me know here or in PM.  Thanks!

Well I have collected a shit ton of FPGA miners of all types, but I would really like about 10-20GH more.  Still buying if you folks are selling.

Have a bunch of working Icarus here, one dead Lancelot(some components oxidated), and 3 dead Icarus.
Buy some working units I throw in a dead one.

Im open, shoot me one PM.

Ok, the diff is up and lifetime earnings for a single FPGA is sadly down to $1 USD per 200MHz/10W chip.  My bitstream is working on x6500 and the next target is ZTEX.  I'd love to have more of either of those, and I am looking for a group of 5 or more Icarus/Lancelot boards, or perhaps Enterpoints for UART-based workers.

You can safely ignore my previous offer of 3x, at current diff the shipping would cost more than the board at those rates!  PM me and we'll negotiate a fair price that gets you a shitload more hashpower of ASICs or the equivalent in BTC for the ride to the moon. 

Also looking for developers.  If you have the tools and can code (verilog, please), I'm happy to ship you a board in exchange for your work in porting to it.  Keep in mind that Webpack cannot build for xc6slx150.

Note: The BE rig is gone, thanks for your interest.  Much thanks to all sellers so far!  Everything is in great condition and just waiting for my new bitstreams.  Which I am debugging, ugh.

I'm interested in getting my hands on a fairly sizable rig > 20GH.  If you have one, let me know.

Thanks!

I have 12x Cairnesmore1 FPGA's (Quad Spartan). I've tested lots of different bitsteams on 2 of the 12 units but they rest run pretty stable @ ~840/ea

Also interested in broken FPGA boards!

Also looking for a good deal on an rpi or two

I forgot to mention - if anyone wants to get rid of FPGAs but still keep mining, I also have 5.4GH of block erupters that I would trade for an FPGA rig.  You can keep hashing at a fraction of the electricity cost.  And the arctic fans I have on them are a whisper - not like the leaf blower sound of a bunch of those little northbridge fans.

Would you accept 0.1 BTC for one?

8x Ztex 1.15y for sale from EU

What's the absolute minimum offer that you'd consider for an Icarus?

I have 3x X6500s, 9x Icarus, 10x Ztex 1.15y

PM me an offer if you're interested in any/all.

Have 4 Ztex clones.  Hashing right now @3500Mh.  Reasonable offers accepted.

I'm placing a standing offer for FPGA miners.  The offer is usually around 3x or 4x what your GH will make in an infinite lifetime, with no electricity costs, if price of bitcoin were to rise to $300 USD, using present diff and 120% increase per month.  You may notice that every single one of those factors is heavily weighted in your favor, then the total price is multiplied by 3!

Go check it out on genesisblock, you can use those numbers or just the real current values.  Multiply by 3, that's our starting negotiation.  I will happily offer more for complete rigs, board I don't have, or just because I'm feeling generous.  Feel free to send the offer you think is fair, and we'll go from there.

Full disclosure - I will reuse the FPGA's for other computation.  I would like to get a few GH worth of each type of board in order to do testing on, to make sure my bitstreams are actually compatible with each type, and nothing crazy happens when they're clustered.  I can't offer the equivalent of a development kit price, because FPGA miners aren't development kits - only a few of the hundreds of IO's are pinned out, there's no way to feed in multiple or other clocks, and the interface is hardwired to whatever the board was built to.  They're only good for bulk computation (if you can develop the bitstreams) or pulling and reballing the FPGAs.  My prices are better than the resale of reballed xc6slx150's.

i have 4 ztex 200mh and 6 x6500 400mh boards. all offers considered  shipping would be from the US
