Q4 2026 buying checklist: DDR4 tail, DDR5 allocation, microSD grades
DDR4 supply is thinning, allocation is the constraint on DDR5, and microSD buyers are being asked to justify endurance grades. A short checklist for the quarter.
Read moreDDR5 has moved from early adoption to mainstream volume. Here is how to plan capacity, frequency and price across the next two quarters.

Capacity planning comes first. The densities that clear fastest are the ones in the middle of the range — 16 GB and 32 GB per module in UDIMM, 16 GB in SODIMM. Ordering those early is what protects a programme from a mid-quarter shortage; leaving them to the last container is what turns a routine reorder into a premium buy.
Frequency is the second decision, and it is usually overthought. DDR5-4800 and DDR5-5600 cover the great majority of commercial, white-box and OEM builds. Above 5600 you are paying a gaming or workstation premium that most channel customers will not notice, so keep the fast bins for the SKUs that advertise them.
Price discipline is the third. Contract what your forecast supports, keep a second source qualified on the same density, and avoid single-lot commitments on fast-moving parts. Buyers who locked DDR4 allocations earlier in the cycle are the ones with room to negotiate today; the same will be true of DDR5 a year from now.
