What to Do If Your RAM Is Actually Underperforming The number you see in CPU-Z is the MHz frequency presented at the undoubled speed.Īnd that’s it! No need to panic, request an RMA number, or spend countless hours troubleshooting a problem that doesn’t actually exist. Introduced way back in 1998 clever engineers devised a way to strictly control the timing of the RAM and, in the process, double the bandwidth.Īlthough some interfaces you’ll come across, such as the memory tool baked into the Windows Task Manager will report the RAM speed at the rate you expect to see-the double data rate-tools like CPU-Z that provide raw spec data about your machine don’t. The modern RAM we used in PCs today is DDR SDRAM (the number after the DDR part, like DDR4 or DDR5, simply refers to the generation of the RAM).ĭDR SDRAM stands for Double Data Rate Synchronous Dynamic Random-Access Memory. When we unpack the acronym we use to refer to RAM, however, the mystery is solved.
