System-specific DDR2 SODIMM for Dell Inspiron 400

This 2 GB module is built for the Dell Inspiron 400 (Zino HD) desktop. It uses a 200-pin DDR2 SO-DIMM form factor running at 800 MHz with CL6 timing. The stick is unbuffered, non-ECC and operates at 1.8 V. Computer Memory Solutions guarantees compatibility with the listed system.

Suits owners upgrading a compatible Dell desktop

Buyers restoring or expanding memory in a Dell Inspiron 400 (Zino HD) will find this part validated for that chassis. It is a single 2 GB rank in a 2Rx8 configuration using major-brand chips. Systems requiring ECC, registered modules, a different pin count, or a memory technology other than DDR2 cannot use this module.

200-pin DDR2 SO-DIMM interface decides fit

The 200-pin DDR2 SO-DIMM edge connector is the sole physical and electrical interface that determines whether the module seats and functions. Matching this exact pin layout and DDR2 signalling to the motherboard slots is the only specification that confirms correct installation.

Questions about this item

Should I pick the single 2GB SODIMM or look for a different capacity for my Inspiron 400?

This module is a single 2GB stick; the system supports up to 8GB total across its two slots, so you can add a second identical module later if you need more memory.

What does the 800MHz rating mean once the stick is installed in the Zino HD?

The memory will run at DDR2 800 speed with CL6 timing at 1.8V, delivering the rated data rate for everyday desktop tasks.

Is the 200-pin DDR2 SO-DIMM interface the limiting factor for performance?

Yes, the 200-pin DDR2 SO-DIMM form factor and PC2-6400 specification set the maximum transfer rate this module can achieve in the system.
