I have successfully overclocked the FusionSilicon X2 (myr-groestl, blake2s, keccak) using V4 control boards. Hashrate is now up to 369 GH/s myr-groestl, 1.5 TH/s blake2s, 92 GH/s keccak - approximately $10/day at current prices.

There are two versions available, up to 23% increased hashrate at 860W draw (at the wall). Please contact me on discord - eureka#4339 - if you would like a copy of this firmware. No dev fee, send me a one time donation for unlimited installs of the firmware.

[11 W]

Interesting new miner from DaYun... specs are very weak, seems to be maybe an old model from their days as PinIdea that they just want to get rid of?

Groestl	2.6 GH/s	200 W
Myr-Groestl	4.3 GH/s	220 W
LBRY	1.536 GH/s	11 W
Pascal	2.3 GH/s	3 W
LYRA2rev2	192 MH/s	25W

Interesting to see how low the draw for LBRY and Pascal are.. perhaps this machine was a testbed for each of the chips they made? Or perhaps to keep the hashrate per device low enough that nobody suspected them secretly mining.

If anybody gets their hands on one of these, I would love to check the firmware image to see how long they have been using them. When PinIdea launched the RR-200 I was able to confirm they had chips in hand and mining Cryptonight as early as August 2017, long before anybody started pointing fingers at secret ASICs.

I have approximately 40 L3+ hash boards available for sale. During their operational lifespan they were never exposed to temperatures above 50c and were continuously operated in the same datacenter environment until they were decommissioned. These boards are all manufactured in July 2017. Due to their age they have been modestly overclocked - all boards are known to operate flawlessly at a minimum of 155 MH/s (nearly 25% above stock). No filth, corrosion, burns or discoloration - having only run in a proper environment means these hash boards are nearly mint condition.

Price is starting at $200/ea for one board, $175/ea for two to four boards, and $150/ea for five or more. Free shipping to the lower 48. BTC or XMR preferred, fiat can be handled via eBay...

I am interested in trading 3 boards in exchange for a PinIdea RR-210 or Baikal Giant N. Contact me if you're interested in trading equipment or are just looking for more detailed photos.
