Err,
ngzhang ? Weren't you supposed to deliver a faster bitstream for the Lancelot any time ?

He seems to have moved on to catch bigger fish. A shame really.

Hmmmm... I haven't blown up any FPGAs lately. This is bitstream-compatible with Icarus, right?

AFAIK yes; Yes it is. The difference between cm1 and icarus should be https://github.com/ngzhang/Icarus/blob/master/FPGA_project/Src/fpgaminer_top.ucf# UCF for a Nexys2 500K board NET "osc_clk" LOC = "J1"; # serial port receive & transmit NET "RxD" LOC = "D1"; NET "TxD" LOC = "B1"; # TTL level serial port: ja3 = rxd, ja2 = txd NET "extminer_txd<0>" LOC = "D22"; NET "extminer_rxd<0>" LOC = "B22"; there is a chance your bitstream to work on one core only.... makomk, what do you think about that? Will your bitstream work? |

Don't bother loshia. Spartan3 500k will not perform faster than 2MH/s....

Under development Modular UPGRADEABLE Miner (MUM). Looking for investors.
Changing one PCB with screwdriver and you have brand new miner in hand... Plug&Play, scalable from one module to thousands.

it is spartan 6 and it is performing...The git file source has been edited probably and what i see is commented |

is the new bitstream project just stale or cancel?

400MH/S from DUAL spartan6 with two cores each. That is FUCKING tragic.
I'm moving my 'demo' single XUPV5 with SINGLE core FROM 160MH/s to 200MH/s later today.
so based on that, two XUPV5 should give me 400MH/s, therefore Two spartan 6 with dual core should be hitting 800MH/s!!!
Plus the shit XUPV5 is only hitting 43 deg. C with an ambient of 25 Deg. C.
HC.

Spartan-6 chips are actually quite a bit worse at Bitcoin mining than comparably-sized Virtex ones, it's just that the price difference more than makes up for it. |

Word. I'm running -3I chips and max out at 300Mhps per chip. |

https://github.com/ngzhang/Lancelotall hardware documents released. also released a 460~ 520 MH/s bitsteam for Lancelot. for test purpose only. please carefully test it with the bit file before flash the MCS file into the EEPROM. Temporarily no technical support for the new bitsteam, Busy with Avalon.

With cgminer 2.4.2 (which I know is not showing HW errors) and --icarus-timing=90 GPU 0: 70.0C 1893RPM | 327.7/342.3Mh/s | A:24 R:0 HW:0 U: 4.22/m I: 4
ICA 0: | 344.2/451.4Mh/s | A:43 R:0 HW:0 U: 7.56/m
I have no idea if this is good or bad |
