2GB DDR3 1600 SODIMM for HP Omni

This 2GB DDR3 1600 CL11 SODIMM module is built for HP Omni 220-1130a, 220-1155xt and 220-1185qd all-in-one PCs. It runs at 1.5V with unbuffered, non-ECC operation and a single 1Rx8 rank. The 204-pin form factor fits the factory memory slots in these specific models.

Upgrade from lower capacity or slower DDR3

The module replaces the original memory stick when the system shipped with less than 2GB or with slower DDR3 speeds. Moving to PC3-12800 CL11 is worthwhile when the board supports 1600MHz and the workload needs more headroom for multitasking. JEDEC and RoHS compliance ensures the upgrade is warranty-safe.

Suits owners of the listed HP Omni models

Buyers with an HP Omni 220-1130a, 220-1155xt or 220-1185qd can install this module directly. Systems that require ECC, registered DIMMs, a different voltage, a higher capacity per slot, or a different DDR generation will not accept this part.

Questions about this item

Does the 204-pin SODIMM fit the HP Omni 220-1130a memory slot?

Yes, the 204-pin DDR3 SODIMM matches the slot used in the HP Omni 220-1130a, 220-1155xt and 220-1185qd all-in-one PCs.

What is the correct orientation when inserting the module into the SODIMM slot?

Align the notch on the module edge with the key in the slot, press firmly until the side clips click, then verify the system reports 2GB at 1600 MHz.

Will the 1.5V DDR3 module need a firmware update or voltage adjustment later?

No, the JEDEC-standard 1.5V DDR3 module runs at its rated voltage without BIOS changes; only replace it if a memory test reports errors.
