SK hynix HMT351U6CFR8C-H9 16GB DDR3 1333MHz 240-pin UDIMM

Kit Capacity and Purpose

This kit provides 16 GB of DDR3 memory across four 4 GB modules for desktop systems that use 240-pin UDIMM slots. It targets owners of older platforms who need to reach the maximum supported capacity without adding heat spreaders that could interfere with large CPU coolers.

DDR3-1333 Interface Limits

The modules run at 1333 MHz with CL9 timing under the PC3-10600 standard, so bandwidth is capped by that specification regardless of faster JEDEC profiles the silicon may support. Systems limited to DDR3-1333 will not benefit from higher-rated speeds, and the unbuffered non-ECC design prevents use in servers that require registered or error-correcting memory.

Plain Module Build and Daily Fit

Each stick lacks a heat spreader, keeping the profile low enough for tight clearances around oversized air coolers or compact cases. The standard 240-pin UDIMM form factor ensures direct insertion into consumer desktop boards, while the 2Rx8 organisation works with typical dual-channel controllers without special population rules.
