  • Patriot Signature Line 32GB (2 x 16GB) 288-Pin DDR5 SDRAM DDR5 4800 (PC5 38400) Desktop Memory Model PSD532G4800K CAS Latency: 40 Voltage: 1.10V Timing: 40-40-40-77 Buffered/Registered: Unbuffered 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. 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. In addition, the latest on-die ECC (Error-Correcting Code) further enhances the acc...

RAM First Word Latency Table (nanoseconds)

Latency is measured in nanoseconds, which is a combination of frequency and CAS. Both frequency increases and latency decreases result in better system performance (when latency is the same, always prefer higher frequency if possible).
