FAQ
What HP notebook models is this memory module compatible with?
This Axiom SODIMM is compatible with multiple HP notebook series including HP Notebook 240 G6, 245 G6, 250 G5, 250 G6, 255 G5, and 255 G6 models; HP EliteBook 725 G4, 745 G4, 755 G4, 820 G3, 820 G4, 830 G5, 840 G3, 840 G4, 840 G5, 850 G3, 850 G4, and 850 G5; HP ProBook 430 G3-G5, 440 G3-G5, 450 G3-G5, 455 G3-G4, 470 G3-G5, 640 G2-G4, 645 G3-G4, 650 G2-G4, and 655 G3; and HP ZBook 14u G4-G5, 15 G3-G4, 15u G3-G5, 17 G3-G4, and Studio G3-G4 mobile workstations.
What is the difference between DDR4-2400 and PC4-19200?
DDR4-2400 refers to the memory technology and data rate of 2400 megatransfers per second (MT/s), while PC4-19200 indicates the theoretical peak bandwidth of 19,200 MB/s. These are two ways of describing the same memory performance: DDR4-2400 specifies the DDR generation and transfer rate, and PC4-19200 specifies the resulting bandwidth calculation (2400 MT/s × 8 bytes = 19,200 MB/s). Both designations appear on this module to ensure compatibility identification.
Is this memory ECC or non-ECC?
This is a non-ECC (Error-Correcting Code) memory module. It does not include error correction circuitry, which makes it suitable for consumer and business notebook systems where ECC is not required. The module uses unbuffered signal processing, which is standard for notebook memory and provides direct communication between the memory controller and DRAM chips without additional buffering components.
What does CL17 CAS latency mean for performance?
CL17 indicates a CAS latency of 17 clock cycles, which represents the delay between when the memory controller requests data and when that data becomes available. While higher CAS numbers indicate more latency cycles, DDR4-2400 operates at a faster clock speed than previous generations, so the actual time delay in nanoseconds is competitive. CL17 at 2400 MHz provides a balanced combination of bandwidth and responsiveness suitable for notebook applications.
Can this SODIMM be used in desktop computers?
No, this module uses the SODIMM (Small Outline Dual In-line Memory Module) form factor with 260 pins, which is specifically designed for notebook and mobile workstation systems. Desktop computers typically use the larger DIMM (Dual In-line Memory Module) form factor with 288 pins for DDR4. Attempting to install a SODIMM in a desktop DIMM slot will not work due to physical size and pin configuration differences.
What warranty coverage does this Axiom memory module include?
Axiom Memory Solutions provides a lifetime limited warranty for this memory module. This warranty typically covers defects in materials and workmanship for the life of the product, though specific terms may vary. The warranty supports the product's reliability claims and provides assurance for long-term deployment in HP notebook and workstation systems where consistent memory performance is essential for business operations.
