What to watch in DDR5 server memory pricing
Memory pricing moves in cycles, and the signals worth watching are not the ones that make headlines.

Transceivers used to be the easy line on a bill of materials. Several things changed at once, and buyers are still adjusting.
For most of the last decade an optical module was the line item nobody worried about. You picked a reach, picked a coding, and it arrived. That assumption has quietly stopped holding, and it catches out project managers who have not bought optics in a year or two.
Three things happened together
The first is that AI fabric build-outs consume optics in quantities that no enterprise network ever did. A single large cluster can absorb more modules than a mid-sized bank's entire estate. When one of those orders lands, it moves the queue for everybody else.
The second is the shift to higher speeds. Manufacturing capacity that used to produce 100G parts has been redirected toward 400G and 800G, and the older lines are not simply idling in reserve.
The third is coding. A module coded for one switch vendor is not interchangeable with the same optical part coded for another. Fragmenting demand across codings means that being out of stock on the exact variant you need is much more likely than the aggregate numbers suggest.
What buyers can do
- Order optics at the same time as switches, not after the switches land
- Confirm the coding on the purchase order, not in a phone call
- Ask whether the reach you specified is actually needed, since single-mode and multimode availability differ week to week
- Keep a small spares pool on site for the codings you run
None of this is exotic advice. It is simply that optics now deserve the same planning attention that switches and servers have always received.
