DDR5 SO-DIMM to DIMM adapter

The Yoetaun JET-5669 adapter lets a desktop motherboard with 288-pin DDR5 DIMM slots accept 262-pin DDR5 SO-DIMM modules normally used in laptops. It is built on a six-layer printed circuit board designed for low noise and complies with the JEDEC MO-337A specification. The card supports memory speeds above DDR5-4800. Installation mirrors a laptop SO-DIMM insertion before seating the adapter into the desktop slot.

Check desktop DDR5 slot and clearance

Verify that your motherboard provides a standard 288-pin DDR5 DIMM socket and that the board layout leaves enough space around the slot for the adapter’s 133.7 by 27.5 millimetre footprint. The system BIOS must be able to initialise the installed SO-DIMM modules at their rated speeds. No extra power connectors or drivers are required for the adapter itself.

Six-layer PCB and JEDEC compliance

The six-layer construction reduces signal noise and helps maintain stability at higher DDR5 frequencies. JEDEC MO-337A compliance ensures the SO-DIMM pinout and electrical characteristics match the desktop DIMM interface. The package contains only the adapter card; no mounting hardware, cables or software are included.

Questions about this item

Does the JET-5669 adapter come with a DDR5 SO-DIMM module or must I buy the memory separately?

The package includes only the adapter card; you must supply your own 262-pin DDR5 SO-DIMM module.

The card is listed as JET-5669 — are there alternative versions or capacities I should consider?

JET-5669 is a single model; there are no other versions or capacity options for this adapter.

The description says the adapter supports more than DDR5-4800 — what does that mean for actual memory speed in my desktop?

It means the adapter can pass through DDR5 modules rated above 4800 MT/s; the final speed depends on your motherboard and the installed SO-DIMM.
