System-Specific Upgrade for IBM x3850

This 8 GB kit contains two 4 GB DDR2 registered DIMMs built for the IBM System x3850 models 8863 and 8864-xxx. It targets administrators who need to expand server memory with guaranteed compatibility. The modules are new and validated for these specific platforms only.

Verify Registered DDR2 Slots and Population Rules

Before ordering, confirm the server uses 240-pin DDR2 slots that accept registered ECC modules at 400 MHz (PC2-3200). Check the system documentation for maximum capacity per socket and the required population order across the four expansion-card sockets. The kit operates at 1.8 V with CL3 3-3-3 timing.

Replaces Slower or Smaller Registered DDR2 Modules

This kit upgrades from lower-capacity or slower registered DDR2 DIMMs when the workload demands more memory within the 64 GB system limit. The jump is worthwhile when current modules restrict virtualization density or database caching on the supported x3850 servers. It does not fit systems requiring unbuffered or newer DDR generations.

Preguntas sobre este artículo

Does the kit contain only the two 4 GB modules or are any brackets or cables included?

The package contains exactly two 240-pin DDR2 registered DIMMs; no brackets, cables or additional hardware are supplied.

Should I choose the CL3 400 MHz kit or look for a different latency for the x3850 8863?

The x3850 8863 and 8864-xxx systems are qualified for this CL3 400 MHz registered ECC kit; a different latency is not required.

Will the 400 MHz rating run at that speed once installed in an x3850 8864?

The modules operate at DDR2 400 (PC2 3200) with CL3 timing when installed in the supported IBM System x3850 8864-xxx.
