Lexar 16GB DDR5 5600 SODIMM – LD5S16G56C46ST-BGS, 262-Pin Laptop RAM, CL46, 1.1V, On-Die ECC, for Laptops & Intel NUC

The Lexar 16GB DDR5 5600 SODIMM is Lexar’s 16GB DDR5 laptop memory module, part number LD5S16G56C46ST-BGS, rated at 5600 MT/s with CL46-45-45-90 timings on just 1.1 V. It uses the 262-pin DDR5 SODIMM format, carries on-die ECC, and is aimed at current laptops, all-in-one PCs and Intel NUC-style mini computers that take removable DDR5 memory. It is in stock in the UAE and ships from Totot.

Why choose the Lexar 16GB DDR5 5600 SODIMM

Recent laptops and mini PCs increasingly ship with a single 8GB or 16GB DDR5 stick, which leaves the second slot empty and runs the memory in single-channel mode. Adding the Lexar 16GB DDR5 5600 SODIMM either doubles a 16GB system to 32GB or brings an 8GB machine to 24GB, and on most platforms filling both slots also lets the memory controller work in dual-channel mode. Lexar describes the module as a way to power up a laptop with next-generation DDR5 performance and says lower power draw helps efficiency and keeps the system cool.

The module is a single stick (1 × 16GB). Lexar also sells a matched 32GB kit (2 × 16GB, part LD5S16G56C46ST-BGD) and a 32GB single module, for buyers who want to replace both stock modules at once.

5600 MT/s, CL46 and 1.1 V on the Lexar 16GB DDR5 5600 SODIMM

Lexar lists a data rate of 5600 MT/s, based on its internal testing, with timings of CL46-45-45-90. The voltage is 1.1 V, which Lexar notes may vary by production batch along with the timings. In plain terms, 5600 MT/s is the current mainstream DDR5 laptop speed, and the low 1.1 V rating is part of why DDR5 laptop memory runs efficiently on battery.

A laptop sets its memory speed from its processor and BIOS. If your laptop’s platform supports DDR5-4800 or DDR5-5200 rather than 5600, the Lexar 16GB DDR5 5600 SODIMM normally runs at that lower supported speed, so you still get the extra capacity. Lexar’s product page lists the module under the JESD79-5A DDR5 standard.

On-die ECC and stability

On-die ECC (error correction code) is built into the DDR5 chips themselves. Lexar highlights it as a stability feature that helps the system stay reliable when pushed. It corrects certain errors inside each memory chip; it is not the same as full ECC server memory, which needs ECC-capable modules and a supporting platform. For a laptop owner, the takeaway is simple: the Lexar 16GB DDR5 5600 SODIMM is designed for dependable everyday operation under heavy multitasking.

Laptops, all-in-ones and mini PCs

Lexar names three kinds of systems for this module: laptops, all-in-one computers and Intel NUC mini computers, plus other systems where space is tight. The module measures 69.6 mm × 30 mm × 1.2 mm per Lexar, the standard compact SODIMM footprint. That makes the Lexar 16GB DDR5 5600 SODIMM a good fit for a home-office mini PC behind a monitor, a gaming laptop whose 16GB fills up during streaming, or a work laptop running virtual machines and large spreadsheets.

Lexar gives an operating range of 0°C to 85°C measured at the module surface and a storage range of -55°C to 100°C.

Before you order the Lexar 16GB DDR5 5600 SODIMM: DDR5 and slot checks

Confirm three points on your laptop’s spec sheet or service manual. The machine must use DDR5 SODIMM: a 262-pin DDR5 module will not fit a 260-pin DDR4 slot because the key notch is in a different position, and the two generations are not interchangeable in either direction. The memory must be socketed; LPDDR5 and LPDDR5X memory in thin laptops is soldered and cannot be upgraded. Finally, note the maximum capacity per slot.

Lexar says it does not guarantee rated specifications when a module is paired with another manufacturer’s DRAM as a dual kit or mixed with other kits. If your laptop came with a different brand, the Lexar 16GB DDR5 5600 SODIMM will often still work, but matching two Lexar modules is the dependable route.

Fitting the module

Power the laptop off completely and disconnect the charger. Remove the base cover as your service manual shows, ground yourself on bare metal, slide the Lexar 16GB DDR5 5600 SODIMM into the SODIMM socket at about 30 degrees with the notch lined up, and press it down until both retaining clips click. DDR5 systems often spend extra time on the first boot while the BIOS trains the new memory, so let it finish without forcing a restart.

Who This Is Not For

The Lexar 16GB DDR5 5600 SODIMM is not for DDR4 laptops, for desktop motherboards that need 288-pin UDIMMs, or for laptops and MacBooks with soldered LPDDR memory. Lexar does not list XMP or EXPO overclocking profiles for this module, so it is not an enthusiast kit for manual tuning. It is a single 16GB stick; if you want a ready-matched pair, Lexar’s 2 × 16GB kit is a separate product.

FAQ

Does the Lexar 16GB DDR5 5600 SODIMM fit a DDR4 laptop?

No. It is a 262-pin DDR5 module; DDR4 laptops use 260-pin SODIMMs with a different notch position.

My laptop supports only DDR5-4800. Will it work?

Yes, in most DDR5 SODIMM laptops it will run at the lower speed the laptop supports, typically 4800 MT/s in that case. Check your laptop’s memory specification first.

Is on-die ECC the same as ECC server memory?

No. On-die ECC corrects errors inside each DDR5 chip; full ECC memory is a different module type that needs platform support.

Can I use it in an Intel NUC or mini PC?

Yes, if the mini PC takes DDR5 SODIMM. Lexar names Intel NUC mini computers and all-in-one PCs as target systems.

Does it support XMP or EXPO?

No. Lexar does not list an XMP or EXPO profile for this module; it is rated at 5600 MT/s, CL46, 1.1 V.

Should I buy two Lexar 16GB DDR5 5600 SODIMM modules for dual channel?

Yes, if both slots are free or you are replacing the stock memory, two matching Lexar modules are the safest dual-channel setup. Lexar also sells a 2 × 16GB kit.
