Server memory kit for Dell PowerEdge T20

This 8 GB kit contains two 4 GB DDR3 unregistered ECC DIMMs rated at 1600 MHz with CL11 timing. It is built specifically for the PowerEdge T20 and targets administrators who need error-correcting memory for entry-level server workloads.

240-pin DDR3 modules without heat spreaders

The sticks use major-brand chips at 1.5 V and a single-rank 1Rx8 organisation. Unbuffered design keeps latency low, while the standard 240-pin layout fits the four DIMM slots on the T20 motherboard without clearance issues.

Matched pair simplifies dual-channel population

Two identical modules are supplied so the system can run in dual-channel mode straight from the box. Buyers who need more than 8 GB or who require registered memory for other platforms should look elsewhere.

Questions about this item

What speed does the DDR3 1600 PC3-12800 rating cap the memory at in practice?

The kit runs at 1600 MHz with a PC3-12800 data rate and CL11 11-11-11 timings at 1.5V.

Will these 240-pin DIMMs fit the four slots in a Dell PowerEdge T20?

Yes, they are 240-pin DDR3 unregistered DIMMs validated for the PowerEdge T20 which has four DIMM sockets.

Do I need to install the two 4GB sticks in specific slots for dual-channel on the T20?

Populate the two sticks in matching-coloured slots (usually 1 and 3) to enable dual-channel; the common mistake is placing them in adjacent slots.
