Non-Binary Memory FAQs

What is “non-binary” memory?

The density of DRAM chips increases periodically in order to keep up with memory capacity demand for computer systems. Historically, the density doubles (e.g. 4Gbit to 8Gbit, 8Gbit to 16Gbit), however with DDR5, we have an intermediary density called 24Gbit, also referred to as “non-binary” memory. The term “non-binary” comes from the divergence of doubling the density. To increase the density, DRAM semiconductor manufacturers must continually improve the design and shrink the silicon wafer process (measured in nanometers or nm) to increase the number of memory cells, within the same package (chip) footprint as the previous generation. By doing this, the same JEDEC PCB (Printed Circuit Board) designs for memory modules can be utilized.

Why choose 24Gbit (non-binary) based modules over 16Gbit?

In client computing, as PC gaming and productivity evolves, so do application requirements. It is not uncommon to see the latest gaming titles recommend or require a minimum 16GB of RAM, with 32GB recommended for smoother game play and multitasking. In data centers applications, such as those driving AI, demand for higher capacities has also increased to process more data in memory. 24Gbit DRAM enables 24GB, 48GB and 96GB DDR5 Registered DIMMs, providing a noticeable bump in capacity across multi-channel memory architectures and more capacity per core, without breaking the bank investing in higher capacities using expensive 3DS stacked DRAM modules (128GB/256GB 3DS RDIMMs).

What systems are compatible with 24Gbit-based modules?

All DDR5 platforms from Intel and AMD are enabled to support 24Gbit memory. However, a BIOS update may be required prior to installing the 24Gbit-based modules.

Can you mix 24Gbit-based memory with 16Gbit?

For JEDEC spec (industry standard) memory modules (ValueRAM, Server Premier, non-overclock), mixing across banks is okay, but we do not recommend mixing memory within the same bank group. Doing so on PCs/laptops disables channel architecture optimization, forcing the memory to perform at half the potential bandwidth. On servers, mixing within a multi-channel bank group is not permitted. If adding memory to the second bank group, it is always recommended to put the higher capacity memory in the first bank. Mixing memory modules or kits in a PC/laptop using overclockable memory (Kingston FURY) is never supported.
