Overview

The Crucial Ballistix BLS2KIT8G3D1609DS1S00 is a 16GB dual-channel DDR3 kit built around two 8GB 240-pin UDIMM modules rated at 1600 MT/s with CL9-9-9-24 primary timings at 1.5V. For DDR3 platforms, 1600 MT/s represents the performance sweet spot: it's the highest natively-supported speed on most Intel Sandy/Ivy/Haswell boards and AMD AM3+ platforms without requiring aggressive overclocking. The certified Intel XMP 1.3 profile means one BIOS toggle takes the kit from JEDEC-default 1333 MT/s to its rated 1600 MT/s configuration without manual intervention.

This kit is the right choice for anyone maintaining or refreshing a DDR3 desktop — upgrading from 4GB or 8GB on a still-capable i5/i7 Haswell system, or populating all slots on an AM3+ board to maximize dual-channel bandwidth. The 2 x 8GB configuration ensures dual-channel operation in standard two-DIMM setups, extracting the full 128-bit bus width of the platform. It is not a performance product for new builds — DDR4 and DDR5 have long superseded it — but as a legacy platform upgrade, it hits the required compatibility, capacity, and stability marks without overcomplicating the selection process.

Frequently Asked Questions

This is DDR3 UDIMM in 240-pin form factor, rated at 1600 MT/s (PC3-12800). It is compatible with desktop platforms using DDR3 slots — primarily Intel Sandy Bridge, Ivy Bridge, and Haswell platforms, along with AMD AM3/AM3+ boards. It is not compatible with DDR4 slots; verify your motherboard's supported memory standard before purchasing.
Yes — it carries certified Intel XMP profiles. In practice, this means you enable XMP in the BIOS and the kit automatically loads its rated 1600 MT/s / CL9 timings without manual sub-timing configuration. On boards without XMP, it will default to JEDEC standard speeds (typically 1333 MT/s) until you enable the profile manually.
The rated timings are CL9 (9-9-9-24) at 1.5V. These are standard DDR3-1600 timings — not particularly tight, but stable and widely compatible across the DDR3 platform range. For maximum bandwidth extraction on Intel platforms, tighter-timed kits (CL8 or CL7) exist, but the performance delta in real-world workloads is marginal.
Yes — dual-channel mode effectively doubles the memory bus bandwidth by activating two 64-bit channels simultaneously (128-bit effective width). For CPU-intensive workloads including gaming and video encoding, the bandwidth improvement over single-channel is measurable in benchmarks, and in some CPU-bound scenarios, tangibly faster in practice.
The heat spreader on this Ballistix kit is a low-profile design by DDR3 enthusiast standards. It should clear most tower CPU coolers without issue, though extremely large air coolers with overhanging heatsink bases on slot 1 may require physical clearance verification against your specific cooler's dimensions.
