Notes

Bank, Rank, DIMM, and XOR Interleaving is supported.
Options include two DIMMs from the same vendor with the same SPD and speed.
FRUs include two DIMMs from the same vendor with the same SPD and speed.
Only CPU 0 DIMMs are accessible in a single CPU system (CPU 0).
Memory is mapped globally and is accessible by any CPU in a multi-CPU system.
Do Not mix DIMM speeds, manufacturers, or part numbers in the same bank.
Mixed speed or mixed SPD DIMMs on the same board is supported in OBP.
Mixed speed or mixed SPD DIMMs in the same bank is not supported in OBP.
Mixed speed DIMMs in different banks serving the same CPU run at the lower speed.
2GB DIMMs are only supported on the faster processor speeds in V210 and V240:
V210 (1.33Ghz)
V240 (1.33/1.5Ghz)

FRU Notes

DIMM 371-1116 was added to 540-6229 and 540-6400 in October 2007.
DIMM 371-1117 was added to 540-6230 and 540-6401 in October 2007.

* The first Netra 240 OBP was 4.11v4. The first Netra 440 OBP was 4.13v0.
** System Board FRUs without OBP 4.16v1 may require removal of mixed banks until OBP is updated.

1GB DIMM Note

Sun Fire V210 systems with the following manufacturing part numbers require Fan Upgrade Kit X7418A when upgrading to 1GB DIMMs:
602-2307-01
602-2307-02
602-2394-01
602-2394-02
The manufacturing part number can be found on a sticker on the right rear side of the system (as seen from the front).

UltraSPARC IIIi Notes

The Memory Control Unit is integrated in the UltraSPARC IIIi.
UltraSPARC IIIi supports 128MB to 1GB single bank DIMMs.
UltraSPARC IIIi supports 256MB to 2GB dual bank DIMMs.
Two DIMMs of the same bank size (single or dual) and memory size form a bank.
Memory error reporting identifies a failing Bank, not a single failing DIMM.
If a memory bank is mixed with single bank and dual bank DIMMs, the memory bank will fail POST. Always replace DIMMs as a pair in the same bank. Do not move single DIMMs between banks unless all DIMMs are identified as the same.

Sun Fire V125 Notes

Factory configurations with 512MB DIMMs may include 370-7972 or 371-1116.
DIMM 370-7972 is a manufacturing substitute for 370-1116 in V125 assembly 602-3652-01.
