AIDA64 Engineer Edition

“AIDA64 Engineer 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 the performance of individual hardware components or the whole system. It is compatible with all 32-bit and 64-bit Windows editions, including Windows 10 and Windows Server 2016.”

AIDA64 shows us that adding a couple of virtual ram slots doesn’t seem to impact bandwidth in any negative way. The Shield DC comes in right around the rest of the 3200MHz kits in our list.

The unusual architecture of the DC DIMMs might make a small impact here, but nothing noticeable, 56.6 ns is quite good.

 

 Passmark Performance Test - Memory Mark - Threaded

“Fast, easy to use, PC speed testing and benchmarking. PassMark PerformanceTest ™ allows you to objectively benchmark a PC using a variety of different speed tests and compare the results to other computers.”

Passmark’s Threaded Memory Mark gives us a score of 37,189, quite good.

 

SiSoft Sandra

“SiSoftware Sandra provides a robust package of diagnostic tools for testing your system and teasing out its problems--or potential headaches.”

SiSoft shows solid bandwidth coming in at a little under 35GB/s.

 

7-Zip

"This form allows you to measure the performance of your computer. The benchmark shows a rating of MIPS (million instructions per second). The rating value is calculated from the measured speed, and it is normalized with results of Intel Core 2 CPU with multi-threading option switched off. So if you have modern CPU from Intel or AMD, rating values in single-thread mode must be close to real CPU frequency. There are two tests, compression with LZMA method and decompression with LZMA method. Once the total passes reach 100, the score is taken.”

ZADAK pulls off the highest dual-channel 7-zip score we’ve gotten yet with well over 68,000 MIPS.

 

Super PI Modded 1.5

“In August 1995, the calculation of pi up to 4,294,960,000 decimal digits was succeeded by using a supercomputer at the University of Tokyo. The program was written by D.Takahashi in collaboration with Dr.Y.Kanada at the computer center. This record should be the current world record. (Details are shown in the windows help.) This record-breaking program was ported to personal computer environments such as Windows NT and Windows 95. In order to calculate 33.55 million digits, it takes 3 days with a Pentium 90 MHz, 40 MB main memory and 340 MB available storage.”

The low latencies and high speed make for a quick Super Pi time of under 7 minutes.

 

Overclocking

Ram overclocking is something almost everyone does, albeit unknowingly, when they apply XMP settings.

XMP for this kit is 3200 MHz at 1.35V at 14-16-16-36 timings.

We start out going up one step at a time, from 3200MHz to 3466MHz.

Unfortunately, we couldn’t make it any further. Even 3500Mhz at 1.4V just wouldn’t boot, and pulling the timings down any at all caused some system instability.

266MHz might not seem like much, but it makes a significant impact. Our read bandwidth climbs from 44.3GB/s to 49.6GB/s, writes go from 47.3GB/s to 52.9GB/s, and copy rises slightly from 42.9GB/s to 47.8GB/s. Latency sees a significant drop from 56.6ns to 51.1ns.

We might not have broken any OC records here, but a small bump makes a very noticeable impact.
