Lexar ARES RGB LD4EU008G-R4000GDWA Review

If you're after a white DDR4-4000 kit and specifically searching for the Lexar ARES RGB white edition, the LD4EU008G-R4000GDWA hits one of the highest DDR4 clocks Lexar sells while matching a white-themed build.

4000MT/s at CL18 is genuinely near the top of what DDR4 does at all, this is a good option for late-life Intel platforms (10th-14th gen) with strong memory controllers, since Intel handles high-clock DDR4 more gracefully than Ryzen's Infinity Fabric constraints do.

Intel vs AMD Fit

4000MT/s DDR4 kits generally make more sense on Intel platforms, which don't share AMD's Infinity Fabric coupling and can just take advantage of the raw bandwidth; on Ryzen you'd typically decouple the fabric clock at speeds this high, eating into the benefit.

Comparison to Alternatives

This is Lexar's higher-clocked sibling to the LD4BU008G-R3600GDLA above, same 16GB capacity but 400MT/s faster at the same CL18 for a white-colored build. If you're on Intel and want the extra bandwidth, this is the better pick; on Ryzen, the 3600MT/s kit is the more sensible choice.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Expert rating6.9 / 10

A genuinely fast DDR4 clock bin best suited to Intel platforms, but the 16GB capacity limits who it's really for.

Best for

Intel 10th-14th gen platforms with strong memory controllers
White-themed DDR4 builds wanting the highest available clock
Bandwidth-sensitive DDR4 workloads on Intel

Not for

Ryzen builds (Infinity Fabric coupling limits the benefit)
Users needing more than 16GB total
DDR5 systems
