Crucial Ballistix Elite DDR4 16GB 2666MHz Memory Kit Review


Memory Bandwidth and Latency Benchmarking

SiSoftware Sandra 2014 SP3:


Sandra needs no introduction as it is the most popular memory performance benchmark available!


Benchmark Results: At 2400MHz we were getting around 50.45GB/s of memory bandwidth. With the Crucial Ballistix Elite DDR4 2666MHz running at its rated speed with 16-17-17-36 1T timings we were able to get around 54.34GB/s of memory bandwidth, which is a nice 7.7% bandwidth improvement when stepping up from 2400MHz to 2666MHz. Things got even more interested when we manually tightened the timings on the kit down to 11-10-10-28 1T as we were able to get 59GB/s of memory bandwidth from the quad-channel 16GB kit at 2666MHz!


AIDA64 Extreme Edition 5.00 Beta:

AIDA64 Extreme Edition 5.00 software is an excellent benchmarking tool for looking at memory performance on any desktop PC.


Benchmark Results: AIDA64 showed that the Crucial Ballistix Elite DDR4 16GB 2666MHz memory kit was good for about 59.2GB/s read and 46.9GB/s write speeds. With the timings tightened up we were able to improve these scores up to 62.7GB/s read and 47.0GB/s write. The tight timings also showed that they helped the copy test as we went from 62.3GB/s to 67.2GB/s by just lowering the timings in the UEFI.


Benchmark Results: When it comes to memory latency we were getting 68.4 ns at 2400MHz and then 64.2ns with the XMP profile at 2666MHz. By manually tightening the timings we were able to get down to 54.9 ns at 2666MHz with full system stability!
