2GB DDR2 SO-DIMM for HP Presario CQ50
This 2GB DDR2 667 MHz SO-DIMM module is built for select HP and Compaq Presario CQ50 notebooks. It uses a 200-pin unbuffered layout with CL5 timing and runs at 1.8V. The single stick provides a straightforward capacity increase for compatible systems.
Suits owners of listed Presario models needing
The module is validated for the Presario CQ50-139WM, CQ50-140US and CQ50-142US. Machines that require ECC or registered memory cannot use this unbuffered non-ECC part. Buyers whose laptops accept only 1GB per slot should look elsewhere. Systems limited to lower DDR2 speeds will not run this module at its rated 667 MHz.
200-pin DDR2 SO-DIMM form factor decides fit
Only notebooks with a 200-pin DDR2 SO-DIMM slot can accept this upgrade. The physical notch position and pin count are fixed by the DDR2 standard. A laptop keyed for a different pin arrangement will not seat the module.

Preguntas sobre este artículo
Should I choose the 2GB single module or add a second stick for the 8GB maximum?
The system supports up to 8GB across two slots; this 2GB stick fills one slot and leaves the other free for a matching module later.
What does the PC2 5300 rating mean once the module is installed?
It runs at 667 MHz with CL5 5-5-5 timing at 1.8 V, delivering the standard DDR2 5300 bandwidth for the compatible Presario models.
Which 200-pin DDR2 SO-DIMM standard does the slot use and what speed does it cap at?
The slot accepts 200-pin DDR2 SO-DIMMs and the module operates at the DDR2 667 (PC2 5300) speed specified for these Presario systems.
