Module identity
The Mushkin Enhanced 991556 is a 2GB DDR2 667 desktop memory module built for systems that require PC2 5300 memory. It targets owners of older platforms needing a direct replacement or a capacity increase.
Bandwidth ceiling
The DDR2 667 interface delivers up to 5.3GB per channel, which is the practical throughput limit of this standard. Higher speeds or larger modules would need a different memory generation and compatible motherboard.
Deciding specification
The 1.80V operating voltage and CL5 5-5-5-15 timing define whether this module matches the board’s memory controller requirements. A mismatch in voltage or timing will prevent the system from posting.

Questions about this item
Should I pick the 2 GB module or add a second one for 4 GB?
Each module is 2 GB; installing two gives 4 GB total if your board has a free slot and supports that capacity.
What does the 667 MHz rating deliver inside a desktop?
It provides up to 5.3 GB/s bandwidth per channel at CL5 5-5-5-15 timing.
Will the PC2 5300 DDR2 interface limit speed on my motherboard?
The module runs at DDR2 667; the board's memory controller caps the actual data rate.
