High-Uptime Mining Hardware, Reviewed Before You Buy

We burn in ASIC rigs on Jeju Island, document failure modes, and deliver procurement briefs that buyers can take to their finance team without guesswork.

What We Measure Before You Sign

Every unit we review must clear the 0.05 PH/s floor. Our field reports cover thermal headroom, firmware stability, fan redundancy, and observed uptime across a minimum 72-hour burn-in window.

72-Hour Burn-In

Every review unit runs under controlled load for a minimum of three days. We log hashrate variance, board temperatures, and unexpected shutdowns before issuing a score.

0.05 PH/s Floor

We only assess machines that meet or exceed 0.05 petahash per second. Below that threshold, uptime economics rarely justify the review cost for commercial buyers.

Procurement-Ready Reports

Deliverables include thermal photography, fan duty-cycle charts, and a plain-language recommendation — not a marketing datasheet reprint.

Review Services

Procurement support built around physical inspection, not brochure specifications.

Buyer Voices

Their burn-in caught a batch of boards that throttled above 38°C ambient. We renegotiated with the supplier before wiring the deposit — saved us roughly three weeks of rack downtime.

— Min-jun Park, Operations lead, Busan colocation facility

The report was thorough and the recommendation was clear. I would have liked faster turnaround on the firmware section, but the thermal data alone justified the fee.

— Sarah Whitfield, Independent miner, Seoul

We used their facility audit before signing a two-year hosting contract in Jeju. They flagged an undersized PDU that the host had not disclosed in the brochure.
