Sandra needs no introduction as it is the most popular memory performance benchmark available!
Benchmark Results: The Sandra Memory bandwidth benchmark found that the Corsair Dominator Platinum Series 16GB 3200MHz memory kit had an aggregate memory performance score of 59.21GB/s with its default Intel XMP 2.0 profile settings, which is a significant step up from what you will find on your typical 2133MHz or 2400MHz memory kit. Manually tightening the timings helped improve the aggregate memory performance to 61.45GB/s. Last week we reviewed the Crucial Ballistix Sport DDR4 32GB (4 x 8GB) 2400MHz memory kit and found that we were able to overclock that kit up to 2666MHz while dropping the timings to an astonishing 12-12-12-30 1T. We kept those results in the chart as we wanted to see how that kit of memory with super tight timings would compare to a higher clocked kit with looser timings. Both kits had right around 61GB/s of memory bandwidth.
AIDA64 Extreme Edition 4.70 software is an excellent benchmarking tool for looking at memory performance on any desktop PC.
Benchmark Results: AIDA64 showed that the Corsair Dominator Series 16GB 3200MHz DDR4 kit with the XMP profile settings had about 63,179MB/s of read bandwidth and 48,498MB/s of write bandwidth. With the manual tightened timings of 15-16-16-30 1T we were able to improve that to 64,220MB/s read with virtually no change at all to the write speeds. The copy test showed we went from 69,201 to 71,112 MB/s, a difference of 2.7 percent. Tightening the timings doesn’t make a significant impact on performance, but enthusiasts crave the best of everything and a 2.7% gain in multiple areas on a system can add up.
Benchmark Results: When it comes to memory latency we were getting 69.9 ns at 2133MHz and 2400MHz with looser timings. We were able to improve that to 58.9ns with the Corsair Dominator Series 3200MHz memory kit with stock settings and then we we got it down to 56.2ns with the manually tweaked timings.
