Dell PowerEdge 1300 upgrades

Soldered memory: none. There are also three 5.25-inch external bays (diskette drive, optional IDE CD-ROM, one other device). No SATA, SAS, NVMe or M.2 support; modern drives would need adapters the sources don't cover.

168-pin DIMM sockets (DIMM_A to DIMM_D) 4 × DIMM · up to 1 GB total · 100 MT/s · ECC

PC100 72-bit ECC SDRAM (not DDR), 64/128/256 MB modules. Max is 1 GB and needs four 256 MB registered DIMMs; unbuffered tops out at 512 MB. Do not mix registered and unbuffered. Fill DIMM_A first with the largest module. Out-of-spec DIMMs may trigger an out-of-rev alert.

Internal SCSI drive cage 4 × HDD 3.5" (Proprietary)

Parallel SCSI (68-pin Ultra2/Wide), no enum value, so marked proprietary. Cage holds up to two 1.6-inch plus two 1-inch drives, or four 1-inch drives. The 3.5-inch form factor is inferred from the drive heights, not stated in the sources. No documented capacity limit.

Internal IDE hard drives 2 × HDD 3.5" (Proprietary)

Up to two EIDE hard drives instead of the SCSI cage (two 40-pin EIDE connectors), marked proprietary since parallel ATA has no enum value. The 3.5-inch form factor is inferred. A BIOS capacity limit is possible on a system this old, so test large drives first.
