cmpunlocker v0.5 Unlocks ECC + 4 SMs on CMP170hx: 1.5TB/s for Half a DGX Spark's Price
chemist_slime · reddit · 2026-10-07
cmpunlocker v0.5 is out, adding ECC support and 4 extra SMs for free on the CMP170hx mining card (gen3 unlock reportedly coming), with 1.5TB/s memory bandwidth versus the 64GB DGX Spark's 273GB/s at less than half the price. The author frames it as a response to Nvidia hiking the 128GB DGX Spark from $4.7k to $7k while launching a 64GB version at $5k. Project: github.com/amoghmunikote/cmpunlocker/releases
