ADATA XPG DDR3 2133 Memory Kit

« Page 2 | Page 4 »


Currently I am limited to a few memory modules to test the ADATA DDR3 21300 Memory kit against and I have nothing that is close to DDR3 2133. The highest performing memory kit that I have on hand is a Kingston Hyper X T1 kit. The specifications of this kit is DDR3 1600 with timing of 9-9-9-27. To compare these two memory kits, I manually set the timings on the ADATA kit to match the timings on the Kingston kit. Without the XMP profile enabled in the BIOS the ADATA DDR3 2133 kit runs at DDR3 1333 with timings of 9-9-9-24 at 1.51v.

Testing Methodology:
System setup:

CPU Intel Core i7 3770K @ 3.5GHz  
Cooler Thermaltake Water 2.0 Pro
Motherboard Gigabyte GA-Z77X-UD3H
Hard Drive Primary: OCZ Agility 3 120 GB SSD
Secondary: Seagate ST2000 2 TB SATA 3
Case Thermaltake Level 10 GT

In our testing we used a few synthetic benchmarks and true application benchmarks. Synthetic benchmarks show off the performance difference that may or may not be noticed in daily usage. We chose software that could test the memory, although CPU performance plays a factor in the benchmarks as well since the memory controller is now located on the CPU.

Synthetic Benchmarks

AIDA 64 is an application that displays information about the hardware in the PC. It includes a Cache and memory benchmark as part of the software. With the timings the same at DDR3 1600 the Kingston kit leads the ADATA kit in all three tests. Kick the ADATA DDR3 kit to the rated 2133 and the ADATA kit clearly out paces the Kingston kit.

MaxMemmis a synthetic benchmark that measures bandwidth of the memory subsystem. The results are delivered in Gigabytes per second or GB/s. Just like we saw in the other graph, the Kingston kits takes the lead when the ADATA kit has the timings manually set to match the Kingston kit. Once again, when the ADATA kit is brought up to DDR3 2133 the lead is erased and the ADATA kit regains the lead. 


Application Benchmarks

Next we move on to real work application testing. WinRAR is a compression application. Compressing files stresses the CPU and memory subsystems. The ADATA kit lags behind the Kingston kit at 1600 but when at 2133 ADATA takes a commanding lead. 


Euler 3D is a fluid dynamic simulator that is based on an aeroelastic test wing. The wing has been tested at the NASA Langly research center as is the standard test used for validation of compressible CFD codes. Euler is extremely sensitive to timings, chipset, and CPU performance. So why do we see the Kingston kit beat the ADATA kit, even at DDR3 2133 speed. Simply put the timings are better on the Kingston Hyper X kit. The timings of the Kingston Hyper X are 9-9-9-27 where as the timings of the ADATA Kit are 10-11-11-30. In this test memory bandwidth and speed are not as big of factor as timings.
