DongGuan Ramaxel Memory Technology — 4 prefixes (MA-L, MA-M)

A MAC address beginning with 8C:2A:8E, B0:4F:A6, or 2C:DA:3F belongs to DongGuan Ramaxel Memory Technology (Limited), a Chinese memory and storage ODM based in Songshan Lake, Dongguan, Guangdong. The company also holds a smaller MA-M block, E8:B4:70:0. These prefixes are typically seen on enterprise or consumer SSDs, DRAM/SDRAM modules, or server and storage hardware built for OEM data-center customers, rather than on end-user client devices.

This is not a bare single-OUI shell registration. DongGuan Ramaxel Memory Technology holds four distinct IEEE prefixes under its own name — three MA-L (24-bit) blocks plus one MA-M (28-bit) block — and a related legal entity, Ramaxel Technology (Shenzhen) limited company, holds a fifth MA-L block, 04:4A:50. External sources corroborate a real, established manufacturer: founded in 1997, reportedly China's top DRAM maker for 14 years and the world's #2 independent DRAM module supplier, with 3,000+ employees and 1,000+ R&D engineers, 122 patents credited to the DongGuan subsidiary, and named partnerships with Intel and onsemi for server-class hardware.

No vendor documentation ties a specific NIC or storage-controller chipset model to these exact OUI blocks; the device-type attribution above is inferred from Ramaxel's product line (DRAM modules, SSDs, flash cards, motherboards, and complete server systems for cloud/data-center OEMs), not confirmed by a spec sheet. IEEE's public OUI/MAC registry data publishes no assignment or registration date for any of these blocks — any third-party "date registered" figure from lookup tools is a database artifact, not an IEEE fact.

IEEE assignments

MA-L 8C:2A:8E, B0:4F:A6, 2C:DA:3F; MA-M E8:B4:70:0, all → "DongGuan Ramaxel Memory Technology (Limited)" [Confirmed] — the IEEE MA-L registry (lines 1018, 23857, 31026), the IEEE MA-M registry (line 2971)

Registry / block sizes

MA-L (24-bit OUI, 3 blocks) + MA-M (28-bit, 1 block) [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry

Related registration

MA-L 04:4A:50 → "Ramaxel Technology (Shenzhen) limited company" — a related legal entity, not counted in this vendor's own prefix total [Confirmed] — the IEEE MA-L registry (line 19724)

Registered address

Primary — No.32, Industrial East Road, Innovation Park, High-tech Industrial Development Zone, Songshan Lake, Dongguan City, Guangdong, China, 523808. A related-entity address (Shenzhen office, 2-5/F North Block Southeast Industrial and Commercial Building, Houhai Road, Shekou, Shenzhen) also appears in the registry data under the sibling registration.

[Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry

Registration date

Unknown — IEEE's public OUI/MAC registry data (Registry, Assignment, Organization Name, Organization Address only) contains no assignment or registration date field; any "date registered" shown by third-party lookup tools (maclookup.app, hwaddress.com, udger.com, etc.) is a database artifact, not an IEEE fact.

[Confirmed] — IEEE MAC address registry specification

Company status / substance

Active, established manufacturer — founded 1997; reported #1 China DRAM maker for 14 years and #2 independent DRAM module supplier worldwide; 3,000+ employees, 1,000+ R&D engineers, 122 patents (DongGuan subsidiary) [Confirmed] — patsnap.com company profile, storagesearch.com

Device types / product line

DRAM/SDRAM memory modules; enterprise and consumer SSDs (2.5in, mSATA, PCIe); flash cards; motherboards; complete server systems for cloud/data-center OEMs [Confirmed for product line; Likely as the source of any specific MAC hit] — storagesearch.com, Intel partner storefront page

Named partnerships

Intel (partner showcase listing); onsemi (server-design customer relationship, 2021 press release) [Confirmed] — intel.com partner storefront, businesswire.com

Website

Unknown — no verified official company domain was found in the sourced research; do not publish a guessed URL [Unknown]

Security context

No CVEs or vulnerability advisories found for Ramaxel/DongGuan Ramaxel hardware or firmware. One dated, low-confidence anecdote (storagesearch.com editor, January 2018) reported Norton/Google warnings against Ramaxel's corporate website at that time — a site-level report, not a hardware finding, and unverified as a current condition.

Special note

Do not publish any third-party "date registered" value as an IEEE registration date for these blocks — IEEE publishes none for MAC/OUI assignments. [Confirmed] — IEEE MAC address registry specification

Related vendors

Ramaxel Technology (Shenzhen) limited company (MA-L 04:4A:50 — related legal entity, same corporate family) [Confirmed] — the IEEE MA-L registry

Analyst note

No vendor documentation confirms a specific NIC or storage-controller chipset model for these exact OUI blocks; the device-type list is inferred from Ramaxel's broader product line, not a confirmed per-prefix spec. Treat device-class attribution as directional (enterprise storage/server context), not a hardware-model identification. [Likely]
