System-specific DDR3 kit

This 32 GB kit contains four 8 GB DDR3 ECC unregistered DIMMs rated at 1600 MHz with CL11 timing and 1.5 V operation. It is built for the IBM System x3250 M5 5458-xxx and uses major-brand chips on 240-pin modules.

Suited for server upgrades

The kit targets administrators expanding an x3250 M5 to its 32 GB maximum across four sockets. It is not for systems that require registered or load-reduced DIMMs, nor for platforms limited to non-ECC memory or a different DDR generation.

Four-module convenience

Supplying four matched sticks in one package removes the need to source individual modules and ensures identical rank and timing across all populated sockets. The vendor provides a limited lifetime warranty against manufacturing defects when purchased directly.

Questions about this item

Does this kit require the IBM System x3250 M5 5458-xxx to have four free 240-pin DDR3 slots?

Yes, the server provides four sockets and the kit contains four 8 GB modules, so every slot must be populated to reach 32 GB.

Will the ECC unregistered modules work if the server currently runs standard non-ECC DDR3 memory?

The x3250 M5 supports ECC unregistered DIMMs; mixing ECC with non-ECC is not recommended and may disable error correction.

How can I confirm the memory is running at DDR3 1600 CL11 after installation?

Enter the BIOS or use a system-information tool; the memory should report 1600 MHz speed, 11-11-11 timings and 1.5 V voltage.
