16GB (1x16GB) 1333MHz 2Rx4 PC3L-10600R DDR3L ECC Registered VLP Very Low Profile Server Memory

This 16GB VLP server memory module provides one very-low-profile DDR3L-1333 ECC Registered DIMM for compatible blade servers, dense compute platforms, storage appliances, and standard servers that accept its electrical specification. The approximately 18.75mm-high PCB is designed for systems where an ordinary 30mm RDIMM is too tall. It is not a SO-DIMM, ECC UDIMM, LRDIMM, HyperCloud DIMM, or standard-height RDIMM.

⚙️ Fit Notes

✓ Confirm that the system requires or accepts a 240-pin DDR3L ECC Registered VLP RDIMM
✓ True VLP height is approximately 18.75mm, compared with approximately 30mm for the standard module
✓ The word “LP” in some IBM, HP, DPN, and reseller descriptions does not necessarily mean VLP. Confirm the actual module height or VLP part-number family
✓ A shorter VLP module can physically fit a slot with standard-height clearance, but exact OEM, BIOS, SPD, thermal, and population qualification still applies
✓ IBM HS22 and HS22V require Xeon 5600-series configurations for this 16GB VLP family
✓ IBM HS23 E5-2600 v2 and HX5 type 7872 are not approved for 46C0599 in IBM’s official compatibility matrix
✓ NetApp appliances should use the exact OEM-qualified VLP FRU because generic DIMMs may fail firmware or SPD validation
✓ PC3L-10600R is not the same as PC3L-10600E
✓ Do not mix VLP RDIMMs with UDIMMs, LRDIMMs, HyperCloud DIMMs, or incompatible rank organizations
✓ This 16GB module uses 4Gb DRAM technology. Older systems limited to 16GB 4Rx4 PC3L-8500R memory may reject it
✓ Update the BIOS, System ROM, or firmware before installing higher-density memory
✓ A second processor must be installed before its attached DIMM sockets can be populated
✓ The module may downclock to 1066 or 800 MT/s where required
✓ Follow all OEM channel-balancing and memory-population rules
