The Dell PKCG9 is an 8 GB memory module for compatible PCs and servers. It provides one memory module in a 240-pin DIMM form factor, for systems designed to accept this type of memory.
The module uses DDR3L memory and runs at 1600 MHz, with the PC3L-12800R designation. It is registered (buffered) and supports ECC, making its configuration suitable for systems that use registered error-correcting memory. Its rated memory voltage is 1.35 V.
This is a single 8 GB module, identified by the part number PKCG9. Its practical role is to add memory capacity to a compatible PC or server; the exact platform must support registered DDR3L DIMM memory.
