64MB DDR2 667MHz DIMM for Dell 537

This 64MB DDR2 SDRAM module runs at 667MHz with PC2-5300 bandwidth. It uses a 240-pin unbuffered non-ECC design rated at CL5 5-5-5 timing and 1.8V. The stick is built with major-brand chips in a 2Rx8 configuration and carries the CMS limited lifetime warranty.

Ideal for restoring a single slot in a Dell

The system accepts up to 4GB across two sockets so this module suits a light capacity top-up. Machines that require ECC or registered memory cannot use this unbuffered non-ECC part. Builders working on any platform other than the specified Dell 537 series should verify compatibility before purchase.

240-pin DDR2 interface decides fit

The memory physically fits only DDR2 240-pin DIMM slots keyed for PC2-5300 operation. A motherboard with a different pin count or a newer DDR generation will not accept this module.

Questions about this item

Will the 240-pin DDR2 DIMM fit the Dell Inspiron 537 desktop memory slots?

Yes, the 240-pin DDR2 DIMM matches the two slots in the Inspiron 537 desktop.

What is the correct way to seat the module, and what step do people often miss?

Align the notch with the slot key, press down firmly until both side clips snap shut; the step often missed is checking that both clips are fully engaged.

When should this 64MB DDR2 stick be replaced?

Replace it if the system fails POST, shows memory errors in diagnostics, or if you upgrade beyond the 4GB maximum supported by the motherboard.
