SKU CH-VCBT-9E3XZ

8GB DDR4 2666MHz CL19 260-pin SODIMM adds fast, low-voltage memory for compatible HP laptops

  • Capacity8GB
  • Type260-Pin DDR4 SO-DIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.20V
  • ECCNo
  • 8GB capacity adds multitasking headroom for everyday workloads
  • DDR4 2666MHz speed matches PC4-21300 system requirements
  • CL19 latency at 1.2V delivers standard JEDEC performance
  • 260-pin SODIMM form factor fits compatible HP laptop slots
  • Non-ECC unbuffered design suits consumer notebook platforms

Compatible DDR4 SODIMM for HP part numbers

This 8GB DDR4 2666MHz CL19 module replaces HP part numbers 3TK88AA, 3TQ35AA, 4VN06AA and 937357-800 among others. It fits laptops, notebooks and all-in-one systems that accept 260-pin DDR4 SODIMMs. The unbuffered non-ECC design operates at the standard 1.20V voltage.

Suitable for single-slot upgrades.

Buyers who need error-correcting code memory or registered modules should look elsewhere because this stick is non-ECC and unbuffered. Systems limited to lower DDR4 speeds will still run the module but at the platform's maximum supported rate. Users requiring more than 8GB per slot must choose a higher-capacity part.

Speed rating PC4-21300 confirms 2666MHz operation

The PC4-21300 designation matches the 2666MHz data rate and CL19 latency specified for this module. Verify your system's supported memory speed before purchase to ensure the correct match.

商品問答

Will the 260-pin DDR4 SO-DIMM fit my HP laptop that uses the 3TK88AA part number?

Yes, this 260-pin DDR4 SO-DIMM is a compatible equivalent for HP part numbers including 3TK88AA, 3TK88AT, 3TQ35AA, 4VN06AA, 937236-855 and 937357-800.

What is the correct way to seat the SO-DIMM, and what step do people often miss?

Align the notch on the module with the slot key, insert at a 30-degree angle, then press down firmly until both side clips click into the notches — the step often missed is pressing down hard enough to engage both clips.

Does this 1.2V DDR4 module need any firmware updates or periodic replacement?

No firmware updates are required; the module is a passive component with no moving parts and is covered by a lifetime warranty, so it does not need scheduled replacement.
