  • Tested 4800MHz frequency ensures reliable operation

Capacity and purpose

This 8 GB DDR5 module is built as a direct replacement for the PNY MD8GSD54800-TB. It targets desktop owners who need a single stick to restore or expand system memory without changing platform.

Speed and voltage limits

The stick runs at 4800 MT/s with a CL40 latency at the standard 1.1 V DDR5 voltage. The PC5-38400 rating defines the maximum bandwidth the memory controller can sustain, so the module will not exceed that ceiling even if the board supports higher data rates.

Installation notes

The 288-pin DIMM seats in any standard desktop DDR5 slot; no heat spreader means a low profile that clears most CPU coolers. The usual mistake is mixing this unbuffered non-ECC stick with registered or ECC modules, which prevents the system from posting. Verify the motherboard accepts 4800 MT/s DDR5 before fitting.
