Goldshell CK5 CK6 Control Board Brand new replacement Controller

Goldshell CK5 CK6 Control Board Replacement | Brand New Controller for Nervos CKB Miners

The Goldshell CK5 / CK6 control board is the OEM-spec replacement controller for the Goldshell CK5 (12 TH/s Nervos CKB, 2400W) and CK6 (19.3 TH/s, 3300W) Eaglesong miners. The board is the brain of the miner: it coordinates the Eaglesong algorithm operations across the hashboard chain, manages chip frequency and voltage, exposes the miner's web interface, and drives the cooling system. When the controller fails, the miner stops generating Nervos CKB rewards — making a pre-tested replacement controller a high-priority repair part.

Standard failure modes on Goldshell controllers include component aging on the SoC voltage rails, network controller damage from power surges, and capacitor degradation after 12-18 months of continuous duty. The replacement board ships with 72-hour stress testing and pre-configured firmware — plug-and-play installation with no technical setup needed for stock Goldshell firmware.

When to Replace the CK5 / CK6 Control Board

• Miner stops hashing or shows errors on the web dashboard — controller cannot drive the hashboards.
• Miner unreachable on the network — IP not responding, web interface not loading despite power LED on.
• Boot loop or watchdog reset — controller boots, fails self-test, reboots, never reaches mining state.
• Communication errors between hashboards — controller cannot establish stable signal to the chain.
• Visible damage — burnt components, scorched PCB, lifted ICs from surge events.

Specs and Features

• 72-hour stress tested before shipping — verified under sustained load.
• Pre-configured firmware — plug-and-play install on stock Goldshell setups.
• Industrial-grade components — built for 24/7 mining operations.
• Full Eaglesong support — optimized for maximum Nervos CKB mining efficiency.
• Prevents communication errors between hashboard chains.
• Anti-static bag included for safe handling during installation.

FAQ — Goldshell CK5 / CK6 Control Board

Q: Will this fit the CK6 SE variant?
A: The CK6 SE (17 TH/s, 3300W, 194 J/TH) uses the same control board family but check the specific revision against your existing controller before ordering. Email us with photos of your existing board if unsure.

Q: Does this work on the Goldshell HS5 or KD5?
A: No — HS5 (Handshake) and KD5 (Kadena) use different control boards with different algorithm support. The CK5 / CK6 board is specifically for Eaglesong / Nervos CKB. We carry separate replacement controllers for the HS5 and KD5 / KD6 platforms — see related products below.

Q: How do I diagnose control board vs hashboard failure?
A: If the miner has no IP / no web interface / power LED stuck (not blinking through boot pattern), the control board is likely failed. If the IP responds but hashboards report communication errors, the issue is downstream — possibly hashboard chain failure. A bench test fixture is the fastest way to confirm.

Q: Do I need to re-flash firmware after installation?
A: For stock Goldshell firmware, no — the board ships pre-configured. If you're running custom firmware, re-flash via SD card after installation.

Q: Bulk pricing for fleet operators?
A: Yes — email contact@lys-sz.com for volume pricing on Goldshell CK-series control board stock.
