Targeted HP Omni upgrade

This 4GB DDR3 SODIMM is built specifically for the HP Omni 220-1130a, 220-1155xt and 220-1185qd all-in-one systems. It addresses the memory ceiling on those models with a single JEDEC-standard module that installs without configuration changes. Buyers needing higher total capacity than one 4GB stick provides should verify their chassis slot count before ordering.

204-pin DDR3 form factor

The module uses the standard 204-pin SODIMM edge connector and runs at 1.5V unbuffered, matching the electrical requirements of the listed Omni platforms. CL11 timing at 1600 MT/s aligns with the PC3-12800 specification so the memory controller trains at rated speed automatically. No heat spreader is fitted, keeping the profile low for tight all-in-one chassis clearance.

JEDEC and RoHS compliant

Compliance with JEDEC and RoHS standards means the upgrade is warranty-safe for the supported HP systems. OWC validates every module in its own lab and backs the part with a limited lifetime warranty plus free technical support. The package contains only the memory stick; no tools, cables or software discs are included.
