System-specific DDR3 upgrade for HP desktops

This 8GB kit from Computer Memory Solutions targets owners of HP Business Desktop 4000 Pro, 500B and 505B systems who need more memory for everyday workloads. The two 4GB modules arrive as a matched pair and carry a limited lifetime warranty from the manufacturer.

DDR3-1333 CL9 1.5V unbuffered non-ECC

The kit runs at DDR3 1333 (PC3 10600) with CL9 9-9-9 timing at 1.5V. Each stick is a 240-pin 2Rx8 DIMM without a heat spreader, built on major-brand components and validated for the listed HP platforms.

Dual-channel pair for four-slot boards

The motherboard provides four DIMM slots; modules may be installed one at a time but must be added in like pairs to enable dual-channel operation. A 64-bit operating system is required to address the full 8GB, otherwise the system may report 3.5GB or less. The memory bus operates at 1066MHz per HP documentation. Buyers needing ECC, registered modules or capacities beyond 8GB should look elsewhere.

Questions about this item

Will the 1333 MHz modules actually run at that speed in my HP 4000 Pro?

HP documentation states the memory bus runs at 1066 MHz, so these DDR3-1333 modules will operate at the lower 1066 MHz speed once installed.

Does the PC3-10600 rating match the motherboard's DDR3 slot specification?

Yes, PC3-10600 is the standard designation for DDR3-1333, and the 240-pin DIMM form factor fits the DDR3 slots in the listed HP Business Desktop models.

Will the two 4 GB sticks fit the four DIMM sockets in my 500B Microtower?

The kit provides two 240-pin DIMMs; the system has four sockets and requires modules to be added in like pairs for dual-channel operation, so this pair occupies one channel.
