  • Four 4 GB modules enable dual-channel operation

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.

Questions about this item

Should I choose the 16 GB kit or the single 4 GB module?

The 16 GB kit contains four matched 4 GB modules for quad-channel bandwidth, while the single module adds 4 GB to an existing bank.

What does the 1333 MHz rating deliver in a real desktop?

It provides DDR3-1333 transfer rates at CL9 latency, matching the PC3-10600 bandwidth ceiling for typical desktop workloads.

How does the 240-pin DDR3 interface limit performance?

The 240-pin UDIMM slot caps speed at DDR3-1600 (PC3-12800), so this kit runs at its rated 1333 MHz without headroom for higher clocks.
