HP 497158-C01 Compatible DDR3 Upgrade

This 4GB DDR3 1333MHz PC3-10600 DIMM is an A-Tech replacement module built for HP systems using part number 497158-C01. It runs at 1.5V with CL9 latency and uses an unbuffered non-ECC design. The 240-pin form factor fits standard desktop DDR3 slots for straightforward installation.

Sustained Load Behaviour

Under continuous workloads the module maintains its rated 1333MHz frequency and 1.50V operating voltage without throttling. Unbuffered operation keeps latency predictable during extended multitasking or background tasks. Quality assurance testing validates reliable performance over long sessions rather than brief bursts.

DDR3 Interface Limits

The DDR3 standard at 1333MHz caps theoretical bandwidth at the PC3-10600 level regardless of module brand. CL9 timing represents the minimum cycle delay the interface allows at this speed. A single 4GB rank cannot exceed the density ceiling defined by the DDR3 JEDEC specification for unbuffered DIMMs.

Questions about this item

How much heat does the 1.50V DDR3 1333 module add when running all day?

At standard 1.50 V DDR3 voltage the module produces only modest warmth; a normal case airflow is enough to keep temperatures in check during continuous use.

What must my desktop already have to accept this 240-pin DIMM?

A free DDR3 DIMM slot on a motherboard that supports 1333 MHz unbuffered non-ECC memory at 1.5 V.

Will this CL9 4 GB stick work alongside my older PC3-10600 modules?

Yes, it matches the 1333 MHz speed and 1.5 V voltage, so it will run at the same timings as existing PC3-10600 DIMMs.
