IBM 8MB 72-pin SIMM RAM – Parity, Vintage 9-chip Module Rare

IBM 8MB 72-pin SIMM RAM – Parity, Vintage 9-chip Module, Untested
Selling an IBM 72-pin SIMM RAM module, 8MB capacity with 9 chips (8 data + 1 parity), part number IBM89X8922.
11 cm long, 72 pins IBM part number: 89X8922, vintage 1990s Parity (ECC) for business-class PCs and workstations Untested, pulled from a vintage system
Great for retro PC builds, IBM collectors, or restoring period-correct machines.See photos for details. Sold as-is. Main Chip Code: IBM89X8922
This is an IBM-manufactured or branded DRAM chip, made specifically for IBM (hence the IBM code). The “8832 0376” and “98 98” are likely batch/date codes (probably 1991 manufacture).

PCB Markings: 65X6239, 65x6254, 6266, F 2506 8579: These are IBM part numbers for the PCB design—common on IBM memory modules, especially PS/2 series and other business PCs. 01-880E 91 aim-MI0 RU 94V0:
“94V-0” is a PCB flammability standard. The other codes are internal IBM designations.




Capacity Estimation 9 chips:
Most 30-pin SIMMs with 9 chips are 1MB or 4MB modules (parity). Given IBM’s tendency to use parity in business machines, it’s likely a 1MB 30-pin SIMM (9-chip, with parity) or possibly 4MB if the chips are “large” (for the era).
If you can give me any more numbers printed directly on the chips themselves (sometimes under “IBM89X8922” will be a smaller code like “41256” or “414400”), I can try to be even more precise.But IBM modules like this, with parity and these codes, are most commonly 1MB 30-pin SIMM.
