HP desktop compatible 8GB DDR3 SODIMM

This 8GB DDR3 module is built for HP 6300 Pro, Elite 8300, Pro 4300, EliteDesk 800 G1, ProDesk 400 G1 and 600 G1 systems. It uses the 204-pin SO-DIMM form factor required by those platforms. The unbuffered, non-ECC design matches the memory architecture specified for these business desktops. Buyers needing ECC error correction or registered modules for server platforms cannot use this product.

Standard DDR3 voltage and speed

Operating at the DDR3-1600 PC3-12800 standard, this module runs at the JEDEC 1.5 V specification for this memory generation. Power draw and thermal output are consistent with typical DDR3 SO-DIMM operation at this frequency. No additional cooling or voltage adjustment is required beyond the system defaults. Systems limited to lower memory speeds will downclock the module automatically.

204-pin SO-DIMM physical fit

The 204-pin edge connector matches the SO-DIMM slots found in the listed HP desktops. Installation follows the standard keyed insertion method for this form factor. The module height conforms to the SO-DIMM outline used in these chassis. Builders working with full-size DIMM slots or proprietary memory boards cannot install this module.

Questions about this item

How do I install this 204-Pin DDR3 SODIMM in an HP EliteDesk 800 G1, and what step is often missed?

Power off the HP EliteDesk 800 G1, unplug it, open the chassis, align the notch on the 204-Pin DDR3 SODIMM with the slot key, press firmly until the side clips click, then close the case before powering on — the step often missed is fully seating the module so both clips engage.

What maintenance or replacement will this 8GB DDR3-1600 module need over time?

No routine maintenance is required for this 8GB DDR3-1600 SODIMM; replacement is only necessary if a memory error appears or if the HP ProDesk 400 G1 or Elite 8300 PC is upgraded to a platform that uses a newer memory generation.

What limit appears first when this PC3-12800 SODIMM runs sustained workloads in an HP 6300 Pro PC?

The DDR3-1600 speed and 8GB capacity set the performance ceiling; sustained heavy workloads on the HP 6300 Pro PC will hit the bandwidth limit of PC3-12800 or the capacity ceiling before any thermal throttle occurs on this unbuffered non-ECC module.
