2488H V5: BIOS Memory Capacity Short by One DIMM

Observed capacity difference

The source’s 2488H V5 POST/BIOS screen reports less memory than physically installed:

Its comparison screen shows the expected total:

The difference is 32768 MB, matching one of the 32 GB modules in the source inventory. Both screens identify BIOS 6.83, release date 06/29/2019 and a 2488H V5; their existing system-number masking remains intact.

Inventory does not establish usable capacity

The source says BIOS/BMC inventory lists 32 installed modules, with no BMC memory alert. Its English inventory excerpt lists 32768 MB modules and other empty slots:

An enumerated module or absence of a SEL alert does not prove that every rank was enabled for use. An AC power cycle did not clear the discrepancy in this case.

Serial initialization evidence

The source prose says Socket0/Channel0/DIMM0, but its pictured log explicitly says Socket0, Channel0, Dimm1, Rank0 and Dimm=0x1. The final service location given by the source is DIMM001. This translation preserves the actual log and identifies the prose mismatch rather than relabeling Dimm1 as Dimm0.

Case conclusion

The source attributes reduced usable memory to isolation after an initialization fault and recommends replacing the module at DIMM001. Confirm the physical location using the exact platform’s slot map and complete diagnostic evidence; this case is not a universal socket/channel-to-label conversion. Recheck usable capacity, inventory and new error logs after the approved service procedure.
