Overview
The Infineon HYS64V8300GU-7.5-C is a 64MB PC133 SDRAM module sold under the HP OEM part number 1818-8149. This classic memory module is designed for legacy personal computers and server systems that require Synchronous DRAM (SDRAM) at 133 MHz bus speed. The 168-pin DIMM form factor and CL3 latency make it suitable for systems built in the late 1990s through early 2000s era.
Key Features
- 64MB capacity — standard density for legacy PC and workstation upgrades
- PC133 speed — 133 MHz bus speed matching legacy motherboard specifications
- Non-ECC, unbuffered — compatible with standard consumer-grade systems
- CL3 latency — typical timing for SDRAM modules of this era
- 168-pin DIMM — standard physical form factor for ATX and legacy platforms
- Infineon manufacturing — reliable OEM-quality memory chip
