Vengeance® LPX 32GB (4x8GB) DDR4 DRAM 2666 MHz C16 Memory Kit Review (CMK32GX4M4A2666C16)

AIDA64

AIDA64 Extreme is an industry-leading system information tool, loved by PC enthusiasts around the world, which not only provides extremely detailed information about both hardware and installed software, but also helps users diagnose issues and offers benchmarks to measure the performance of the computer.
AIDA64 Extreme has a hardware detection engine unrivaled in its class. It provides detailed information about installed software and offers diagnostic functions and support for overclocking. As it is monitoring sensors in real-time, it can gather accurate voltage, temperature and fan speed readings, while its diagnostic functions help detect and prevent hardware issues. It also offers a couple of benchmarks for measuring either the performance of individual hardware components or the whole system. It is compatible with all 32-bit and 64-bit Windows editions, including Windows 8.1 and Windows Server 2012 R2.

AIDA_Copy

AIDA64 sees the Ripjaws 4 mid-chart and churning out 55183 MB/s and coming in ahead of the Corsair 2666 MHz kit which has looser timings. When we apply the Corsair Vengeance’s secondary XMP it jumps ahead of the Ripjaws. We suspected the wheat in the chaff here was the secondary XMP provided by Corsair to turn the Vengeance kit into a 2666 MHz killing kit. RAM is a bit different from a lot of products. Many reviewers talk about one kit kicking another kit’s butt, but the winning kit is rated at 3 GHz and the losing kit is rated at 2.4 GHz. The only loser in that equation is the reviewer and the reader who is losing out on an honest evaluation of the kits. You can really only treat review comparison as win or lose when the speeds and timings are exactly alike and that happens rarely.

Aida_Latency

The Vengeance kit jumped to third spot on the Latency chart turning in a great Latency of 71.7ns. Perhaps the CL 16 tighter timings are holding the kit back a little.

AIDA_Read

The Read benchmark inAIDA64 sees the Corsair Vengeance kit low on the chart running at 2666MHz but throw on the secondaryXMP and it climbs to second behind the Kingston 3GHz kit which thus far has topped the charts in every test. Like we mentioned earlier RAM is all about timings and rated speed. The higher the speed the faster it processes data, but the timings tell the RAM the interval at which it can do each operation so the tighter (lower) the timings the better. Often you will get just as productive a result from tightening the timings of a ram kit as overclocking it to insane speeds. Somewhere in the middle there you can fins a good OC with timings tightened  hair. When tuning RAM always check your tuning results with your favorite RAM benching program. We tend to use a quick and dirty 4M SuperPi because it’s fast and ultra sensitive to RAM speed and timing changes 

Aida64_WriteA

Here in the AIDA64 write test the Ripjaws came in ahead of the Corsair Vengeance LPX 2666 MHz kit by under 200MB/s . However clock the Vengeance kit up to its secondary XMP of 2800 and it comes out ahead. Think about it for a second, we are talking in the 45 – 49000 MB/s range moving data around. Unless you’re doing some serious spread sheeting, rendering or something extremely data intensive (and boring) you’re not going to see much difference to the human eye between the various kits.
