Best Overclocking DDR5 RAM for 285: G.Skill Trident Z5 RGB
Which RAM Is Compatible With the Core Ultra 9 285?
Memory Generation Supported by the 285
The Core Ultra 9 processor 285 only supports DDR5 memory. Other generations of memory are incompatible.
The generation of memory (e.g., DDR3, DDR4, or DDR5) must match what is supported by your motherboard. Motherboards only support a single generation of memory.
To learn more about the difference between DDR5 and DDR4, check out our article: DDR4 vs. DDR5? Which You Should Buy.
Maximum Memory Speeds Supported by the 285
The maximum speed at which you can run PC memory depends on your CPU, motherboard, and the memory itself.
When using DDR5 memory, the Core Ultra 9 processor 285 officially supports memory speeds up to 6400 MT/s. This maximum speed means that stock DDR5 performance will be maximized using DDR5-6400 memory.
When overclocking memory, such as with an XMP profile, you can exceed these stock speeds officially supported by CPUs. We've found that motherboard specifications indicate their supported overclocked-memory speeds. To be able to overclock DDR memory, your motherboard chipset needs to support memory overclocking.
Find which chipsets support overclocking in my article, Which Chipsets Work With Intel's Core Ultra 9 processor 285?.
RAM can also be underclocked to achieve compatibility, which can be a practical solution in certain situations. Underclocking is particularly useful when you have memory that operates at speeds faster than what your CPU or motherboard supports. However, to underclock with precision, your motherboard must support memory speed adjustments. Without such support, the memory may default to a slower speed than the maximum supported speed. We recommend using the maximum speed that both your motherboard and CPU support to achieve optimal memory performance without requiring overclocking support.
To confirm compatibility, you can check the motherboard's specifications. Additionally, we've found that motherboard manufacturers often list compatible memory kits on their websites, making it easier to verify support.

285 ECC Memory Support
Most gaming and general-purpose desktop setups do not use ECC memory.
Error correction code (ECC) memory is a more expensive form of memory typically used for critical server and workstation use cases. The purpose of ECC memory is to detect and correct when a single bit in memory gets flipped unintentionally.
ECC memory will not work unless the motherboard and CPU both support ECC.
The Core Ultra 9 285 supports unbuffered ECC memory with a compatible motherboard.
While the 285 CPU technically supports ECC memory, it requires a server/
When desktop motherboards support ECC memory, it's typically limited to "unbuffered ECC" memory. Server motherboards may support "registered ECC" memory, which allows for additional memory modules.
Before Buying RAM
Before purchasing memory, we suggest that you review your motherboard specification to verify which speeds are supported. For example, if a DDR4 motherboard stated that it supports "DDR4 3400(O.C.) / 3333(O.C.) / 3300(O.C.) / 3200 / 3000," that would mean that it could support DDR4-3400, DDR4-3333, and DDR4-3300 with memory overclocking, and DDR4-3200 and DDR4-3000 at stock speeds. Motherboard specifications also indicate the maximum capacity per stick of RAM (DIMM) and across all slots.
