Please read first: this is an engineering sample (ES), not a retail chip. AMD EPYC 7742 engineering sample, OPN 100-000000053-04, on a blank lid with no model text. It fits Socket SP3 server boards for EPYC 7002 (Rome). Engineering samples need a board and BIOS that accept them; ours runs on a Supermicro H12SSL-NT with BIOS 3.7. Please confirm your board supports Rome engineering samples before you buy.

64 cores / 128 threads, 256MB L3 cache. A unit from this same production batch (BB 1913/1914, March-April 2019) runs in our own Supermicro H12SSL-NT, where Linux reports it as "AMD Eng Sample: 100-000000053-04_32/20_N": 2.0 GHz base, 3.2 GHz boost (retail is 2.25 / 3.4 GHz), stepping 0, all 8 memory channels active, and not vendor locked.

Not vendor locked. These were sold to us as unlocked engineering samples (no Dell, Lenovo or HPE PSB lock), and the unit from this batch running in our server confirms it.

Pulled from a working system. Lids are clean with a light thermal-paste haze; each CPU ships in its green AMD SP3 carrier frame. The photos show the actual lids and serials of the CPUs for sale.

Sold as working pulls. No-returns listing; Money Back Guarantee still applies to items not as described.

You receive one CPU in its carrier frame, no cooler. Ships from Minnesota in a static-safe clamshell inside a padded box.
