HGCHIPS 96GB DDR5-6400 ECC RDIMM (HGD5R series) is the pin-to-pin compatible replacement for Samsung M321RYGA0PB2-CCP — the 2Rx4, CL52, PC5-51200R server module that current Intel Xeon and AMD EPYC platforms identify directly, with no board change and no firmware change. The 96GB tier is the tightest spot segment of the DDR5 RDIMM market: broker pricing runs US$3,641–4,851 per module versus contract references of US$1,310–1,600, after 80–120% quarter-on-quarter increases. The HGCHIPS replacement ships from Shenzhen stock at ¥21,000/pc tax included (≈ US$2,950) — about 30% below the spot mid — within 48 hours, every lot functionally tested on a DDR5 platform with traceable records. Small-batch board validation before full import is recommended; samples ship immediately.

Yes — same 288-pin RDIMM form factor, 2Rx4 organization and CL52 speed profile; current Intel Xeon and AMD EPYC platforms identify it without board or firmware changes. We recommend a small-batch board validation (samples available) before full production import.
Trailing fields are packing/revision identifiers (CCP = standard bulk; CCPKC / CCPW are packing variants of the same module). Electrically the HGCHIPS replacement matches the base M321RYGA0PB2-CCP specification; send your exact BOM line and we confirm suffix equivalence in writing.
¥21,000 per module tax included (≈ US$2,950) — about 30% below the current spot mid of ≈ ¥30,000. Shenzhen stock ships within 48 hours; every lot carries a traceable functional test record.
