1600mhz RAM performance at 800mhz as shown in Task Manager
The original post contains a misunderstanding about DDR specifications. DDR refers to Double Data Rate, but the actual speed is defined by the effective frequency, not just MHz values. The laptop’s label mentions "8 GB DDR4-2400 SDRAM," indicating it operates at 2400MHz effectively. This means the real clock speed is double that number, which is 4800MHz. The distinction lies in how manufacturers present data versus the technical reality. Windows’ displayed frequency can vary based on version and settings, so checking Task Manager or using tools like CPU-Z provides accurate readings. Adjusting XMP profiles can also influence what appears to be the speed.
You're right to double-check this, but your laptop and desktop readings seem inconsistent. The task manager shows a high frequency, while the desktop reports a lower one despite more sticks and XMP settings. It's possible the stick configuration or driver settings are affecting the display. Confirming with another tool might help clarify what's happening.
Task Manager isn't a good choice for tracking frequencies. Use CPU-Z to collect that data and share the results. I'll include the relevant screenshots from CPU-Z along with the information about DDR. This data is confirmed through research on DDR memory.
