Will the bcu owners need to get the DC1613A dongle for hash boost like the vcu's?
Latest information on Discord is that DC1613A is not needed for BCU.
They have received a go from xilinx to control the voltage via the application ?

Yup via the BMC

What is BMC?  Is this an application from xilinx outside vivado?

 Board Management Controller

Need special cable for that?  Accessible through which software?

to op, your website only has  0xbtc and nexus available for download.  where do we get these bitstreams?

Keccak (Smartcash, Maxcoin): 136GH/s (17GH/s per card x eight) ($160/day at Apr-30 prices)
Tribus (Denarius, Virtus): 16.8GH/s (2.1GH/s per card x eight) ($304/day at Apr-30 prices)
Phi1612 (Luxcoin, Folm): 5.2GH/s (650MH/s per card x eight) ($456/day at Apr-30 prices)
Skunhash (Various coins): 10.4GH/s (1.3GH/s per card x eight) ($261/day at Apr-30 prices)

The Sapphire Radeon RX 580 8GB provides hashrate of 800 Hash/s for CryptoNote at Coreclock 1150 MHz and Memoryclock 2150 MHz while consuming 90 watts.
 Gpu Specs

The AMD Radeon RX 580 8GB is a graphics card by AMD. It comes with GDDR5 memory and has 256 bit memory interface or bus width.


The Sapphire Radeon RX 570 8GB provides hashrate of 25 MHash/s for Ethereum at Coreclock 1420 MHz and Memoryclock 2250 MHz while consuming 130W watts.


 Gpu Specs

The AMD Radeon RX 570 8GB is a graphics card by AMD. It comes with GDDR5 memory and has 256 bit memory interface or bus width.

here is the link fore more info

https://miningchamp.com/gpus/150/Sapphire-Radeon-RX-570-8GB-hashrate

My system with 3 RX 570 4GB ETASH bios mod.
Idle: +/- 105W
Etash, +/- 92MH/s: 440W. Around 110W/ 30,6MH/s per card.
CN V1 variant 7 (monero type) around 2750-2800H/s 330-340W. So around 80W per card.

monero settings?

That's neat.  Is the s9 different than the s9i?  s9i already mines at 14.5 per bitmain.

What are you guys mining with the 3 Gb version in Windows 10 besides X16R which is a good addition to latest Nicehash and makes about 0.40 USD per card, I know it sucks but you can't expect more from a 3 Gb version now, with Zcash being totally dominated by the ASICS.

I am also afraid for the first time since I started mining that this maybe the end for SOHO-Small Office/Home miners. I hope I am wrong.

ethereum still works in linux/hive.  Moved a few to Monero now....though performance is weak

Odds Xilinx partnered w/Bitmain and would do a pre-emptive release of ther FPGA hardware before this one?

Odds Bitmain got a hold of some of these boards, figured what parts to "hog" and bought the bulk of the stock?

The pump doesn't have to involve shilling if you got billions to cause bullish action by purchasing an asset, artificially decreasing supply and increasing demand.

In other words: semantics.

That's not pump and dump. That's something else.

Also, keep in mind that trying to manipulate a market by buying large amounts is very risky. If you buy a huge amount, you pay the higher price, and you only make money if the price continues to rise. If the price doesn't continue rising, you will lose money when you sell your huge position.

bumping thread...

I just got a setup stable mining @30/card (ethereum only), but seems to be consuming ~140w/card.  Anyone have similar numbers at lower wattage? Thought these things would mine high 20's at 80 w?

one click bios

1200 core
877 mv
2100 memory

~140w per card seems a bit much.
Have you undervolted both core and memory?
If not, try undervolting memory to 900mV, and if it's stable, try lowering voltage until you find max undervolt.
On this link there is tutorial how to undervolt using OverdriveNtool https://mining.help/

He uses 877mV.
If you undervolt memory to 900mV you can save like 10W at wall, depends on memory type with Samsungs you can go even to 850mV or with most of them. Under 100W with RX 5xx you can go only when you mine Monero and other CN coins. Not really with ETH.
Go below 1180MHz and try 800mV you should be hitting 120W or maybe a bit higher like 820mV depends on card.
Overdriventool is great.

Thanks; got to roughly ~120w/card after compensating for losses @ the power supply. 
1150
850mv
2100 memory
mostly hynix, one elpidia

Simple mining nor Hive have memory  undervolting option so may have to try the overdriventool.

It looks like you don't know what "pump and dump" means. Read this:

What is 'Pump And Dump'

Pump and dump is a scheme that attempts to boost the price of a stock through recommendations based on false, misleading or greatly exaggerated statements. The perpetrators of this scheme, who already have an established position in the company's stock, sell their positions after the hype has led to a higher share price.


The pump doesn't have to involve shilling if you got billions to cause bullish action by purchasing an asset, artificially decreasing supply and increasing demand.

As far as I know the "property" definition changed in the 2017 tax cuts act.  Now it must be declared as a quasi-currency following forex rules.  Meaning take a hit on every trade that made gains.

Being a multi-billion dollar company that's proven to be pretty cunning, does anyone know if they have a crypto trading desk/s?  With the amount of mining power they possess, it wouldn't be that difficult to prioritize one coin over the other, and dump money to trigger cascades of protections.

I posted a video on the modded KU040 board:
https://www.youtube.com/watch?v=cim1-ubz4oE

It does work remarkably well, and with over-volting the hash rate could be quite amazing (compared to the low price of the board), but as it stands it requires a few further tweaks in order to be stable.  I need to add a potentiometer to the voltage control to raise the voltage AFTER the bitstream has started hashing and I also need to implement the gradual-power up feature.  Without these, the board is extremely sketchy/unstable and prone to freezing and requires reprogramming and several tries to get it to start up properly.  Not viable for large scale mining (at all), currently.

Running at 600MHz it only starts getting errors around 0.86V (default core voltage 0.95V since it is a 20nm FPGA).  With my heat sink holding the FPGA at a remarkable 40C, there is massive room for hash increases.
I believe it can run at more than 750MHz at higher voltage and maybe even 800MHz.  In the video it is running at 600MHz (x4 cores = 2.4GH/s).



#teamNexysVideo?

are the ku04 sold out everywhere?  Decently sized for immersion cooling

Bumping this thread.

Link to drive is dead, no link to download OS.  Ended up getting it off some other mining site but doesn't seem to work.  I boot to Ubuntu just fine, bash starts up, goes to "miner in screen -r" but when I type that in, no miner is seen.

cards recognized, basically seems to get stuck after fan speed is defined.

I posted a basic oneBash that can be used to replace the one from the stopgap img on GitHub: https://github.com/hartmanm/rxOC/blob/master/oneBash

It should work and can be changed to support any client or pool.

I no longer have any AMD GPUs and will not update rxOC anymore; it is End of Life.

I managed to get it running yesterday by editing the bash file and running claymore 11.9.  I was unable to manually overclock the cards so hash was lower than on hive...And today it just refused to boot up after updating drivers to blockchain ones.  Re-imaging drive now.

Why ditch AMD?  Seems like decent bang for buck ATM...

I got one way back when white listed it as a possibility.  ROI was about the same as the xilinx per his numbers.  Been collecting dust as I hope white will have time to release bitstreams some day Sad

I, for one am glad I got in b4 the 25% Trump tariff on semi-conductors...

Though perhaps Xilinx builds in Taiwan?

The tariff is paid when the product moves from China to the US (imported), not when the product is purchased.  





Point being?  You think xilinx uses all made in USA components?  I don't even know if they assemble domestically.

That is my point.  We could be screwed with the Xilinx delay.  If they are assembled in China, and arrive after the tarrifs are in place.... someone will have to pay the 25% tarrifs.  And I can't imagine that would be Xilinx.

ah, gotcha....I guess I was under the assumption that the boards' final assembly was done state's side and were waiting for a few smd's.  Which in retrospect sounds dumb/inefficient.
