DDR2667DDR2800

DDR2667DDR2800 is not a standard memory specification and does not align with JEDEC naming conventions used for widely adopted DDR memory generations. The exact meaning of the term is unclear and references are sporadic, often appearing in informal contexts, catalogs with unclear notation, or possible miscommunications. Because there is no official specification tied to this exact label, its interpretation can vary by source.

Possible interpretations include that DDR2667DDR2800 denotes two different speeds within a single listing (for example a dual-kit or mixed-speed pairing), a manufacturer’s marketing code, or simply a typographical or formatting error intended to represent other designations. It could also be a concatenation of two separate labels, such as DDR266 or DDR2800, rather than a single standardized standard.

For context, standard DDR memory designations follow established tiers. DDR (DDR1) memory had common speeds like 266, 333, and 400 MT/s (often written as PC-2100, PC-2700, PC-3200). DDR2, DDR3, and DDR4 use speeds expressed as MT/s such as DDR2-800, DDR3-1600, DDR4-3200, with actual performance dependent on motherboard, memory controller, timings, and overclocking. A cited speed of 2667 MT/s would be unconventional within mainstream JEDEC tiers, though enthusiasts sometimes describe nonstandard speeds in overclocked configurations.

If this label appears in documentation, it is advisable to confirm the exact model number, memory type, and compatibility with the target motherboard or system from the manufacturer or reliable sources, since the lack of a formal specification makes interpretation and validation uncertain.
