Running at a moderate pace, half the usual speed.
Hello, I'm trying to figure out my RAM issue. For about a year now, my 8GBx2 setup has been running at 1333MHz instead of the rated 2666MHz. I've looked in the BIOS and it says 2666MHz, but Task Manager shows 1333MHz. My machine is an AMD Ryzen 2600X with 8GB DDR4, installed on an Asus B450-F Gaming motherboard.
DDR typically shows half the advertised rate because it operates at double speed. Updated November 20, 2020 by Dissitesuxba11s
The actual frequency is 1333MHz, but the effective speed is 2666MHz (or MT/s), which explains the name DDR – Double Data Rate. It's strange that Task Manager displays it this way, but it's not an issue.
TL;DR: Your RAM operates normally now. It runs at 1333 MHz, handling two transfers per clock cycle, totaling 2666 MT/s. The advertised 2666 MHz is accurate, though some sources may list it as 1333 MHz. Software tools and motherboards confirm the correct figure.
The issue lies with the fact that my friends using 3200MHz RAM also display 3200MHz in their task manager. I didn’t realize my own RAM was running at 2666MHz during the first three months after installation. After roughly three months, it dropped to half and has stayed that way ever since.
I've been checking other discussions too, and most agree with what I said. Could be a coincidence or maybe I misheard something.
It seems you received the same response multiple times, which likely indicates it's correct. You might have misheard or misread the answer. Let me know if you need further clarification!
