Antminer L7 guide

VNISH firmware for Antminer L7

Antminer L7 is a Scrypt miner, so it needs different tuning expectations from BTC SHA-256 models. Use this page for L7-specific install checks, safe first-run tuning and tool selection.

MonitoringWatch HW errors and temperature deltaErrors often reveal bad boards or over-aggressive settings

L7 first run

After flashing, restore pools, let the miner run at conservative settings, then let autotune finish before changing frequency/voltage targets.

When to avoid overclock

Avoid aggressive overclocking if the PSU is marginal, ambient temperature is high or one board already shows higher error rates than the others.

Fleet use

For multiple L7 units, create one known-good preset from a stable miner and roll it out in small batches instead of applying a high-power profile to every unit at once.

Frequently asked questions

Does L7 use the same VNISH package as S19?+

No. L7 is a Scrypt miner and needs L7-specific firmware.

Can VOU help with L7 installs?+

Yes. VOU helps discover and manage supported miners, but the firmware package and method still must match the model.

What should I check after L7 flashing?+

Pools, worker names, fan response, temperature spread, HW errors and reject rate.
