The 128MB GRP and L.C. Upgrade Kit (MEM-GRP/LC-128) is a factory-tested memory expansion module that adds 128MB of high-performance GRP and low-latency cache to supported systems.
This upgrade kit is compatible with all devices and controllers that support standard 72-pin SIMM GRP expansion and low-latency cache slots as specified in the product datasheet.
Power down your system, open the chassis, locate the GRP and L.C. memory slots, align the module’s gold pins with the socket, press firmly until it clicks, then reassemble and power on.
No special tools or advanced expertise are required; a Phillips-head screwdriver and adherence to standard electrostatic discharge precautions are sufficient for installation.
You will experience faster data access, reduced latency in memory-intensive tasks, and overall improved system responsiveness in mission-critical applications.
Yes, the kit is fully plug-and-play; once installed, the system auto-detects the additional 128MB memory without requiring BIOS configuration changes.
GRP stands for General Read/Write Performance memory, and L.C. denotes Low-Latency Cache, both engineered to enhance throughput and reduce access times.
Yes, each 128MB module undergoes rigorous burn-in testing, error-checking, and validation to ensure compliance with industry reliability standards.
The kit includes a one-year limited warranty covering defects in materials and workmanship under normal operating conditions.
Yes, we offer a 30-day return and exchange policy for unopened, unused kits, subject to our standard terms and conditions.
No additional firmware or driver updates are needed; the system firmware automatically recognizes and utilizes the new memory.
The module measures 5.25" x 1.0" x 0.3", weighs 0.4 oz, and features a 72-pin gold-contact edge connector operating at 5V.
Standard ground shipping delivers within 3–5 business days in the continental U.S.; expedited options are available at checkout.
The additional 128MB module draws an extra 0.75W under load, a negligible increase that does not significantly impact overall system power usage.
