4 GB DDR4 2666 SODIMM for laptops and NAS

This 4 GB DDR4 module runs at 2666 MHz with CL19 latency and 1.2 V operation. It uses the standard 260-pin SO-DIMM form factor and is unbuffered non-ECC memory. The stick is designed as a direct replacement for QNAP part numbers RAM-4GDR4A0-SO-2666, RAM-4GDR4T0-SO-2666 and RAM-4GDR4T1-SO-2666. It suits laptops, all-in-one PCs and compatible NAS units that accept DDR4 SO-DIMMs.

Fits 260-pin DDR4 slots and runs at 1.2 V

The module installs in any 260-pin DDR4 SO-DIMM socket and will down-clock to 2400 MHz or 2133 MHz if the platform requires it. No heat spreader is fitted, so it clears tight spaces in thin laptops and compact NAS appliances. Because it is unbuffered and non-ECC, it works in consumer platforms but not in systems that require registered or ECC memory. The low voltage helps keep power draw minimal in portable devices.

Replaces slower DDR4 or fills an empty slot

Use this module to upgrade from 2133 MHz or 2400 MHz DDR4 where the system supports 2666 MHz operation. It also adds capacity when a free SO-DIMM slot is available. The jump is worthwhile when the platform can run at the higher 2666 MHz data rate and the workload benefits from extra bandwidth. Buyers needing ECC, registered DIMMs or capacities beyond 4 GB per module should look elsewhere.

商品問答

How does the CL19 latency at 2666 MHz affect sustained throughput?

At CL19 each access waits nineteen cycles; at 2666 MHz that is the primary timing limit you hit during long workloads.

What heat or noise should I expect from this module running all day?

The stick has no heat spreader and draws 1.2 V, so it runs silently and adds minimal warmth inside a laptop or NAS chassis.

Which slot and voltage must my system provide for this SODIMM to work?

It needs a 260-pin DDR4 SO-DIMM slot operating at 1.2 V; the module is backward compatible with 2400 MHz and 2133 MHz buses.
