The Ultra ULT31908 2GB Kit DDR2 800MHz PC2-6400 desktop RAM consists of two 1GB modules, providing a total capacity of 2GB. This RAM operates at a bus speed of PC2-6400 (DDR2-800), making it suitable for enhancing the performance of desktop computers requiring DDR2 memory. Designed by RAM, this product offers reliable and efficient memory expansion for your computer system.

Ultra ULT31908 2GB DDR2 desktop memory kit consisting of two matching 1GB modules. Both sticks have been tested and confirmed working and are being sold together as the matched pair shown in the photos.

Each module is labeled ULT31908 and the original label identifies the kit as 2048MB PC2-6400 800MHz DDR2 (2x1024MB). These are full-size 240-pin desktop DIMMs intended for compatible systems that use DDR2 memory. The modules feature silver metal heat spreaders covering the memory chips, giving them the classic performance-memory appearance common to enthusiast DDR2 kits of the era.

This is a useful replacement or upgrade kit for older desktop computers, retro PC builds, legacy workstations, repair projects, and systems that specifically support 240-pin DDR2-800 memory. DDR2 is not physically or electrically interchangeable with DDR, DDR3, DDR4, or DDR5, so buyers should verify their motherboard or system specifications before purchasing.

Compatibility depends on the motherboard, chipset, BIOS, supported memory density, speed, and other system requirements. A system may operate DDR2-800 memory at a lower speed when required by the motherboard or processor. The ULT31908 part number and PC2-6400 specification are clearly visible in the photos to help with compatibility verification.

Only the two memory modules pictured are included. No retail box, manuals, motherboard, computer, or other accessories are included.

Condition Assessment: Very Good. Both 1GB modules are tested and confirmed working. Clean overall with intact contacts, PCBs, labels, and silver heat spreaders. No significant scratches, dents, corrosion, or physical damage observed.
