Cisco Memory Issues – Field Notice

Field Notice
Cisco has issued a field notice alert for UCS 16GB, 32GB, and 64GB memory DIMMs. This hardware failure is due to a deviation in the memory supplier's manufacturing process -– most DIMMs were manufactured in late 2020.

From Cisco:

“Most DIMMs with this manufacturing deviation will exhibit persistent correctable memory errors. If left untreated, the DIMMs might eventually encounter an uncorrectable memory event. If encountered during runtime, uncorrectable errors will cause a sudden unexpected server reset. If encountered during Power-On Self-Test (POST), the DIMM will be mapped out and the total available memory reduced. In some cases, a boot error might be seen”

Do you have an affected DIMM?

If you believe you have an affected DIMM(s), please feel free to reach out to your Vista Account Manager to discuss possible replacement options!
