Performance issues with RAM not meeting advertised speeds.
Performance issues with RAM not meeting advertised speeds.
Hey there, I got a similar issue too. I installed the GB450 B450 sh2 with a Ryzen 5 2600 and 16GB Corsair Vengeance LX3200M RAM. In the BIOS I chose XMP and saved, but when checking in CPU-Z the DRAM frequency shows 1596.2 MHz instead of the actual speed. What should I try next? Thanks!
TL;DR: your RAM operates at the right frequency. It runs around 1600Mhz, meaning it makes millions of ticks per second. Each tick moves two data units, which is why DDR technology uses double data rate. Manufacturers often label it as 3200Mhz for simplicity, but it's actually 3200MT/s.
CPU-Z displays a lower figure rather than actual performance; it reflects the memory makers' claims of double speed. This happens since each MHz equals two transfers, meaning the real rate is higher than what appears. One could say the true speed is 3200MHz, but in practice it operates at about 1600 ticks per second. This comparison highlights how different the perceived and actual performance can be.
