SC1 manufacturer historical baseline

Obelisk’s May 2018 engineering update gives 550 GH/s at 500 W based on final-preproduction core testing. No tolerance was published, and later firmware improvements were anticipated.

Physical and acoustic boundary

  • 15.3 × 6.5 × 5.6 in (approximately 388.6 × 165.1 × 142.2 mm)
  • Approximately 9 lb (4.08 kg)
  • Final measured acoustics were not published. DCR1 had an early target below 65 dB, not a final guarantee.

Hashboard, electrical and firmware boundary

This comparison lane follows the authenticated installed SC1 hashboards. Obelisk later offered board conversions, so enclosure appearance alone cannot prove algorithm. The original shipment included a PSU and country-specific cable, but facility voltage, current and connector were not published.

Legacy OB1 controller recovery instructions apply only to authenticated first-shipment SC1a/DCR1a hardware. No generic firmware CTA is exposed. Current network compatibility, revenue, profit, home suitability and heat-use conclusions are unavailable.
