Dell Optiplex GX240 Memory Upgrade

This 512 MB PC133 SDRAM DIMM is built for the Dell Optiplex GX240 series. It runs at 133 MHz with CL3 latency and 3.3 V unbuffered operation. The 168-pin module uses major-brand chips in a 2Rx8 configuration. It installs directly into the system's two available sockets.

Suits owners expanding a GX240 to its 1 GB limit

Buyers needing ECC or registered memory should look elsewhere, as this stick is non-ECC and unbuffered. Systems requiring DDR or faster SDRAM standards cannot use this module. The single-stick package also means a second unit is required to fill both slots.

168-pin PC133 interface determines fit

The 168-pin DIMM form factor and PC133 speed rating are the decisive specifications for GX240 compatibility. Only modules matching this exact pin count and signalling standard will seat and function in the motherboard slots. Verify the 168-pin requirement before ordering.

Questions about this item

Does the 3.3V CL3 DIMM run cool and quiet in a Dell Optiplex GX240 that stays on all day?

Unbuffered SDRAM has no moving parts and draws little power at 3.3V, so it adds negligible heat and makes no audible noise during continuous operation.

What must the Dell Optiplex GX240 already have for this 168-pin PC133 module to work?

The system needs a free 168-pin DIMM slot and a motherboard that accepts PC133 SDRAM at 133 MHz; the GX240 provides two such sockets and supports up to 1 GB total.

Can I keep the original 133 MHz SDRAM sticks and add this CM6464133DIMM module alongside them?

Yes, the GX240 has two DIMM sockets and a 1 GB maximum, so this 512 MB stick can fill the second slot while the original module remains installed.
