Kingston Technology Corp. KVR26S19D8/16 ValueRAM DDR4-2666 SODIMM 16GB REG CL19 1.2V laptop RAM

SKU CH-6Y40-JBAEW

Registered DDR4 SODIMM running at 2666 MHz with 16 GB capacity, CL19 latency and 1.2 V operation

  • Registered design improves data integrity in heavy workloads
  • 16 GB capacity expands multitasking headroom for demanding applications
  • DDR4 2666 MHz speed delivers responsive system performance
  • CL19 latency at 1.2 V balances timing and power efficiency
  • 260-pin SODIMM form factor fits standard laptop memory slots

16 GB DDR4 SODIMM for registered-memory notebooks

This 16 GB DDR4 SODIMM runs at 2666 MHz with CL19 latency and 1.2 V operation. It uses a registered, dual-rank x8 organisation on a 260-pin module. The stick is built for notebooks that require registered memory rather than standard unbuffered SO-DIMMs. Buyers should confirm their platform accepts registered modules before purchase.

Sustained-load behaviour with registered design

The registered buffer adds one clock cycle of command delay, which steadies the memory bus when all ranks are active for long periods. CL19 timing at 2666 MHz delivers PC4-21300 bandwidth without the voltage headroom needed for higher speeds. Thermal output remains consistent because the module operates at the standard 1.2 V DDR4 level.

Verify registered-memory support and slot count

Check the laptop manual or vendor specification sheet for explicit registered SODIMM support; many consumer notebooks accept only unbuffered modules. Ensure a free 260-pin DDR4 slot is available and that the system BIOS recognises registered DIMMs. If the platform requires unbuffered memory, this module will not function.

Questions about this item

How much power does the 16GB DDR4-2666 module draw at its rated 1.2V voltage?

The module operates at 1.2V, which is the standard low voltage for DDR4 SODIMMs, reducing power draw and heat during continuous all-day use compared to higher-voltage memory.

What laptop slot and chipset features are required to run this registered 260-pin SODIMM?

The system must provide a DDR4 SODIMM slot that accepts 260-pin registered modules and a memory controller that supports registered DIMMs; consumer laptops typically do not support registered memory.

Will this CL19 registered stick work in an older notebook that only takes unbuffered DDR4 SODIMMs?

No, because this module is registered (buffered) and older notebooks designed for unbuffered DDR4 SODIMMs cannot use registered memory.
