What´s the best FPGA to mine? I have $10,000.00 to spend with miner.

First, there is no "best" FPGA.
Second, there is a whole subforum for FPGA topics.

IMHO you should purchase $10,000 worth of BTC's, wait until the price doubles, and then sell $10k of your BTCs to buy hardware.

Cost/Mhs the best is BFL.

Yes, and you will get your BFL 3 months after you order it, and it isn't usable with p2pool.

Yes, that's why I'm still use GPUs.

And what about Icarus (lancelot)?

It's a little out of date, and does not include specs for BFL, but here is a small comparison: http://bitcoinfpga.com/

Instead of asking what is the best, it would be more ideal for you to do some research yourself. For example, we could tell you "BFL is the best", but then you would be subject to shipping delays, and would be using a LOT of power. Or, we could tell you "Ztex is the best", and then you would find out that it costs significantly more than other solutions for less speed, even though it will sip electricity and has a 2 year warranty.

If you want to spend that much, get someone else to invest alongside, and get a larger device such as LargeCoin, or the BFL Mini-rig. Or, as others have said, learn some trading strategies and start playing the market, you could even invest in Pirate's operation (Bitcoin Savings and Trust), if you want to earn interest.

Like everyone here has already point out; you need to do some more research on to see what suits your needs. Having said that, let me point in the direct of a few good products:

1.) www.fpgamining.com - X6500 (Dual Spartan 150's), right now its at 400mh/s for about $580 USD + accessories. It consumes about 16-19w of power per unit and since Rev. 3.0 hit the market it's definitely a solid product (tempurature sensors and push-pin mounts for DIY north-bridge heatsinks.

2.) www.ztex.com - Ztex Quad ( Quad Spartan 150's), so far is the only quad spartan FPGA on the btc market. Not much info on it yet, but looks pretty sweet in terms of its performance (800mh/s+), the price tag not so much ($1000 EUR / $1300 USD)

P.S. Butterflylabs is an option as well, but I'll let others cover that one.

Ztex does have a 2 year warranty,but ROI is about 14 months.190-210mh/s @ $414 , 8-10 watts

X6500 has no warranty & the same ROI time frame.360mh/s @ $580 , 20 watts

Those two are great but the ROI spoils it for me.They both use alot less power though.

I don't think either of those comes with a power adapter,so you need to get a wall wart or buy cables to adapt to a PSU.

BFL has a 6 month warranty (not great,but better than none),ROI is about 6 months,include 2-3 month ship time & its around 9 months.Comes with power adapter. 830mh/s @ $ 600 , 80 watts.

Thats the way I look at it  8)

Why not? Is it a software or a hardware issue?

Firmware and software - but BFL has stated that they are working on modifications to the firmware so that it can support P2Pool, and then the associated software would need to be changed to support it.

So do all BFL products use proprietary software and hardware? As in, they will not work with 3rd party miner software?

No, the API is open, and cgminer and ufasoft's miner both work with it (and others too, possibly). They are developing their own software, but it hasn't been released yet.
The hardware and firmware are not open though.

I use CGMiner with mine, currently in BAMT

Icarus 469$ (multiple of 30)

Stable : 380 MH/s  (or use 400MH/s not stable)

bitminter has support for bfl

As does MPBM

bfl's work great on bitminter

that's right. it was the easiest way and it's the fastes, too.

depends on what part of the world you are and how many pieces you are willing to buy.

my personal choice that can be bought right away(there are still some pieces being sold): as a Brazilian I know the high kw/h price and high temperature are revelant and I would not wait BFL queue time.

BFL time delivery chart is going down, and I got mine today  8)

Option 1: (Easiness 9/10)(convenient 9/10)(Power 9.5/10)(Money:4/10)

And BFL is the best to go, I just got one and for only $599 it yields 832 Mhash/80 Watts.

With $10,000 pick up 14 of these super units.
They are very small like 1/5 of a video card I have one
and it runs really well. Plug them all into one computer, and done!

This would yield you 11648 MHASH


Option 2: (Easiness 3/10)(convenient 1/10)(Power 3/10)(Money:10/10)
Though the complete best for pure money making will require risers + PSUS + 5830s, rewiring of your house,
using heaters splitting the wires you can get 3000 Watts from heaters.
At least for some.


If done right you can yeild over 30 Giga hashes.

Which I am getting 2.4 Ghash trade of 5830s in exchange for my Single BFL unit.
And plan on trading my other 4 which I can yeild over 11 giga hashes for as little as $2500.


Though the option one that I suggest is the easiest.

Wait, let me get this straight: You're buying BFLs, and trading them for large amounts of cheap video cards (5830s and 5850s) and wiring said cards into a hacked up 3000 watt space heater to save on not buying PSUs?

regardind BFL/x6500/icarus/lancelot being sent to you

you may want to consider shipping costs from USA or China, the size of each packets(number of boards within) and posture of the customs for these packages. But remember, due to the general large volume of work and lack of people at Correios I believe that everything that comes from China is easier to go unnoticed and not get caught by the tax man

I am still buying PSUS, just this is the only way I Can get enough power in the house, and properly for some of you.
I am plugging a out plug into where the heater is, removing the heater, using the wires that are 240 V, splitted them off, two red wires, into 120 V and yielding 3000 Watts.

I will still need PSUS to power the mother boards and gpus, and to get the power from the wall alone.
But thats my hacked version of power in a house with not so much power.

Read up on it;
This Below is basically What I am doing, very simple.
