PC2700

PC2700 is a designation for a family of DDR SDRAM memory modules designed for desktop computers, standardized by JEDEC as part of the DDR1 era. It corresponds to DDR-333, meaning the memory supports 333 million transfers per second. The PC-2700 label denotes a theoretical peak bandwidth of about 2,700 MB/s (approximately 2.7 GB/s); the actual transfer rate is typically 2,664 MB/s (333 MT/s × 8 bytes).

Form factors and electrical characteristics: PC2700 modules use the 184-pin DIMM form factor and operate at around 2.5 volts, with some modules tolerant to slightly higher voltages. Typical module densities ranged from 128 MB to 1 GB, and common configurations included various latency timings such as CL2.5–3–3–7, depending on the specific module.

Compatibility and usage: These memory modules require a motherboard with DDR1 (184-pin) DIMM slots. They are not compatible with newer DDR2, DDR3, or DDR4 systems due to different pinouts and signaling. PC2700 was commonly used in mid-2000s desktops, often alongside processors and chipsets that supported DDR1.

History and status: PC2700 was introduced around 2002 as the successor to PC2100 (DDR-266) and preceded PC3200 (DDR-400). It provided higher bandwidth within the DDR1 family but has since become obsolete with the advent of DDR2 and later generations. Today, PC2700 is primarily of interest for legacy systems and retrocomputing.
