Here is the formula we’ll use for true memory latency: True memory latency (ns) = (2000/RAM Speed) (ns) x CAS latency. Therefore, true memory latency of DDR4-3200 CL22 = 13.75 ns and. true memory latency of DDR5-4800 CL40 = 16.67 ns. However, it doesn’t stop here! What is a 1rx8 ram stick… what is a 2rx8 ram stick.. these are not normal terms used to describe computer memory. Usually when describing RAM for compatibility reasons, they are described by Size, Speed, and Type. So, in my computer, I would say, I have 2 sticks of 16gb 3200Mhz RAM no clue what you’re description about the RAM you have means. Overview of Memory Chip Density. Data that is being managed by a memory module is stored on cells contained in the small black DRAM chips attached to the memory module's printed circuit board. As memory technologies mature, more of these cells can fit into a chip. This allows for the same memory capacity in fewer chips, or higher total memory Memory. The XPS 8930 has four DIMM slots. Your computer supports 8 GB, 16 GB, 24 GB, 32 GB, and 64 GB UDIMM DDR4 memory (up to 2400 MHz for i3 processor and up to 2666 MHz for i5/i7/i7k processors). NOTE: Use slots DIMM1 and DMM3 if you need to use two memory modules. Lower latency means faster ram. Latency is usually shown on spec sheets as CAS or CL. This is important. This is the reason you shouldnt mix different ram sticks. Latency is generally represented by a number, for consumer ram its usually between 14 and 19 with 14 being on the higher end and 19 being on the lower end. . 359 91 480 227 202 236 286 138

can you mix 8gb ram with 16gb ram
