Kit 4GB (4x1GB) DDR2 PC2-5300 667MHz
Elpida EBE11UD8AGWA-6E-E
HP 377726-888 UDIMM Non-ECC
Kit includes 4 Elpida EBE11UD8AGWA-6E-E 1GB RAM modules, for a total capacity of 4 GB. These are DDR2-SDRAM PC2-5300 memories designed for desktop computers with DDR2 UDIMM slots. The modules are Unbuffered (UDIMM) and Non-ECC, which are typical features of desktop systems of that era. Each module uses a 64-bit data bus, operates at the standard voltage of 1.80V, and features a Dual Rank configuration.
Key Make, Model, and Features
The modules are produced by Elpida with part number EBE11UD8AGWA-6E-E and HP Part Number HP 377726-888. Each module has a capacity of 1 GB, for a total of 4 GB in the kit.
The memory type is DDR2-SDRAM Unbuffered (UDIMM), Non-ECC, with a 64-bit width and Dual Rank configuration. The operating voltage is SSTL 1.8V.
According to the SPD data, all four modules were manufactured in 2007, week 24.
Frequency, Voltage, and Timings
The memories support DDR2-667 (PC2-5300) frequency, corresponding to 333.3 MHz real clock and 667 MT/s in DDR mode.
The main profile detected at 333.3 MHz is:
- DDR2-667 (333.3 MHz): 5-5-5-15
- CAS Latency: CL5
The SPD also indicates the following supported profiles:
- DDR2-533 (266.7 MHz): 4-4-4-12
- DDR2-400 (200.0 MHz): 3-3-3-9
The motherboard will automatically select the appropriate profile based on its settings and memory controller specifications.
In-Depth Timings
Timings regulate memory access latency. For operation at DDR2-667, the SPD profile indicates 5-5-5-15, with tRCD 15 ns, tRP 15 ns, and tRAS 45 ns.
Lower frequency profiles feature tighter timings: 4-4-4-12 at 266.7 MHz and 3-3-3-9 at 200 MHz.
These parameters are stored directly in the module's SPD Revision 1.2, allowing compatible systems to automatically recognize its operating characteristics.
Compatibility and Configuration
These modules are intended for desktop motherboards with DDR2 UDIMM slots compatible with PC2-5300 / DDR2-667 memory.
The kit consists of four identical 1 GB modules, providing a total capacity of 4 GB. This four-module configuration is ideal for systems featuring four DIMM slots.
If supported by the motherboard and chipset, installing the modules in the correct slots enables Dual Channel operation, increasing available memory bandwidth.
Final compatibility depends on motherboard specifications, chipset limitations, and the maximum supported RAM capacity.
Item Condition
All four modules were pulled from the same desktop computer and verified via their SPD data. The technical specifications listed match the data retrieved from the modules, including brand, part number, capacity, frequency, timings, voltage, and configuration.
