What are XMP and EXPO?
When you install memory in a system, there is a set of standardized speeds/timings your memory will run at. This standard is called JEDEC. This is why you see DDR4 and DDR5 memory speeds like DDR4-2133, DDR4-2666, and DDR5-4800. These are standardized speeds that all memory manufacturers adhere to. Outside of JEDEC are additional performance … Read more
DDR4 vs DDR5 RAM
DDR5 memory bandwidth is initially at 4.8 Gbps per pin, compared with DDR4’s 3.2 Gbps. Future versions are expected to double DDR4’s, going up to a maximum of 6.4 Gbps. DDR4 frequency ranges from 1866 to 3200 MHz (without overclocking), while DDR5 ranges from 4800 to 6400 MHz initially. DDR4 maximum density is 16 Gb … Read more
