With cgminer 2.4.2 (which I know is not showing HW errors) and --icarus-timing=90

Quote

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

U 7.56/m means 550MH/s

Then this is good

ALtho, it's probably an illusion from some statistical variance

GPU 0: 70.0C 1894RPM | 326.8/331.8Mh/s | A:141 R:1 HW:0 U: 4.22/m I: 4
ICA 0: | 282.6/424.1Mh/s | A:200 R:2 HW:0 U: 5.99/m

That's 430 MH/s

Wow ! very good news ! Thank you Ngzhang !

I'll try that asap

ps: it's named "42" of course

https://github.com/ngzhang/Lancelot

all 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.

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.

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!!!

Nope, single core each. 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.

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.

LancelotQC runs with around 32°C on the original bistream. i would like to run the x6500 overclocker bitstream, does someone know if that bitstream is adjustable for lancelot??

If you are interested in buying Icarus boards to mine today, then upgrade it to ASIC whenever avalon ASIC is available, check my Icarus sale thread here: https://bitcointalksearch.org/topic/sold-discounted-icarus-fpga-upgradable-to-avalon-asic-115154

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

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

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?
