You technically can, but it will limit your ability to overclock them so you may not hit the rated speed anymore. Also you would alternate them (8+16+8+16), not group them together. Unless you really need >32GB, I would stick with the 16+16 alone. 3. Triethylborane. 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. It'll give you 8gb dual channel RAM (faster) and 8gb single channel RAM. And not entirely sure which video ofa LTT, but a single 16gb stick is indeed slower than 2x8 (because of dual channel). Single ranked 16gb vs single ranked 8gb is not faster or slower. Exactly the same. If there are 4 RAM slots, then you're all set. You should ideally already have your two 8gb sticks set as dual channel, each channel running 8GB for 16gb total. Slot in your new sticks and it'll be 16gb each channel for a total of 32gb. Posted January 26, 2016. This will most likely work completely fine, no need at all to worry. PC SPECS: CPU: Intel Core i7 3770k @4.4GHz - Mobo: Asrock Extreme 4 (Z77) - GPU: MSI GeForce GTX 680 Twin Frozr 2GB - RAM: Crucial Ballistix 2x4GB (8GB) 1600MHz CL8 + 1x8GB - Storage: SSD: Sandisk Extreme II 120GB. 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 Mixing RAM With Different Speed and Latency. Technically, you can install memory units with different speed and latency. But whether the system boots is uncertain. All the memory units installed in a motherboard run at the same frequency. If your system already has slower RAM, there is no point in adding faster RAM. I believe you can just make sure your mobo supports such individual sticks. 32 gigs in a single stick is not very common. I think you can but consider just buying 2x16GB sticks at a higher spees and using just them if you have a Ryzen CPU. Ideally 3200 or 3600MHz. JUM2.

can you mix 8gb ram with 16gb ram
