Patriot Signature 16GB (DDR5-4800, CL40) Desktop RAM

Description

DDR5 Signature Line Features

Patriot’s Signature Line DDR5 memory modules are designed to deliver an immense performance improvement for next generation Intel platforms. Requiring only 1.1V of power, Signature DDR5 modules consume less power and emit less heat despite the increased frequency and speed.

The DDR5 Signature Line introduces several architectural improvements beyond the DDR4 Signature Line worth noting:

Enhanced power improvements include an onboard Power Management IC (PMIC), which provides better control of local voltage regulation while delivering increased threshold protection, simultaneous monitoring, intelligent voltage, and power management.

The Signature Line DDR5 series includes onboard thermal sensors to monitor and protect against thermal issues and better overall reporting. The SPD Hub with I3C/I2C sideband access enables system-level thermal and power management communication — a DDR5 platform standard not present on any DDR4 module in this range.

The latest on-die ECC further enhances the accuracy of data-processing and your overall system’s stability.

Performance Profile

The PSD516G480081 is a 16GB (1×16GB) DDR5-4800 (PC5-38400) 288-pin UDIMM running at 40-40-40-77 timings at 1.1V, unbuffered and non-ECC. Speed is JEDEC-native at DDR5-4800 — no XMP profile, no BIOS configuration required. The module will run at rated speed on any compatible DDR5 platform straight out of the box.

⚠️ No XMP on this module: DDR5-4800 is achieved via JEDEC specification natively — no BIOS tuning required.

Patriot Signature DDR5 vs DDR4 Signature Line

The DDR5 PSD516G480081 is a generational step up from the DDR4 Signature Line modules listed elsewhere in this range — delivering 38.4GB/s bandwidth (50% higher than DDR4-3200), lower operating voltage (1.1V vs 1.2V), on-die ECC, PMIC voltage regulation, and onboard thermal sensing, all at 16GB single-stick capacity. For DDR5-capable systems, this is the entry-level Patriot Signature upgrade.

DDR5 Platform Requirements & Part Number Disambiguation

DDR5 is not compatible with DDR4 motherboards or slots. A DDR5-capable motherboard and CPU is required. Note that the PSD516G480081S (with trailing S) is the SO-DIMM laptop variant — confirm you have the correct 288-pin UDIMM desktop variant (PSD516G480081) before purchasing.

⚠️ DDR5 is not compatible with DDR4 slots: Verify that both your motherboard and CPU support DDR5. Many Intel 12th and 13th gen boards were available in both DDR4 and DDR5 variants — confirm your specific board’s memory type before ordering.

⚠️ Desktop vs laptop variant: The PSD516G480081S (with trailing S) is a 262-pin SO-DIMM laptop module. This listing is for the PSD516G480081 288-pin desktop UDIMM. Confirm the correct variant before purchasing.

⚠️ Single stick = single channel: For dual-channel bandwidth, install a second PSD516G480081 in your motherboard’s recommended paired DIMM slots. Refer to your board’s manual for the correct slot configuration.
