Looks Cool, Acts Cool

The jet wing-inspired design of XPG Z1 combines the carbon texture used for race cars, symbolizing the pursuit of extreme performance. It also features excellent cooling and stable data transfer due to Thermal Conductive Technology and 10-layer PCBs with 2oz of copper to effectively reduce electric resistance and consume less power, which greatly enhances the quality of signal transfer.

Advanced Heatsink Design for Better Cooling Efficiency

Our specifically designed heatsink has better cooling efficiency when compared to the most popular “heat spreader” design on the market.

The Best Choice Gamers & DIY Users

For gamers and DIY users who are always asking for better performance while remaining cool, the XPG Z1 Series module meets their requirements.

2OZ Copper 10 Layer Black PCB

First adopted in DRAM modules by ADATA. This feature was first introduced to the motherboard market by Gigabyte. ADATA was the first to use 2oz of copper in the production of DRAM modules.

Lower Resistance, Lower Temperature, Better Stability

2oz of Copper 10 Layer PCB is helpful in lowering the electrical resistance which comes with the great benefits of a lower temperature, better signal integrity, and better stability.

The evolution of memory is depicted in the picture below. Memory used to require up to 3.3 V to operate, but improved technology has brought us incredible increases in speed and impressive power efficiency.

Amazing Performance with Great Power Efficiency

DDR4 outperforms DDR3 with improved performance and lower power consumption. The operating voltage has decreased from 1.5V to 1.2V, which is a 20% reduction of power, and keeps the system at a low temperature for stable operation. It only requires 1.2V to achieve high clock frequency of 2800MHz for overclockers. Additionally, the SPD (Serial Presence Detect) of XPG Z1 allows direct application without changing settings in the BIOS, facilitating usage and system stability.

Packaging and Product Tour

The memory kit comes in a blister pack with a graphical cardboard insert. The front of the package gives you a good look at the memory through the clear plastic and also offers up a few high level features and specifications. At the back, you’ll find a sticker with the timings, part number, and voltage requirements printed on it. The other two modules can be seen from the back of the package, along with contact information for ADATA’s home office in Taiwan. The cardboard insert unfolds and contains installation instructions and warranty information inside.

Testing for Stability at Rated Speed/Timings

With the memory installed in our test bed, we start off with a stability check at the advertised speed/timings/voltage. To perform the stability check, we use our Ultra-X R.S.T. Premium USB memory tester. The folks at Ultra-X provided us with the tester, and we’re proud to be one of only a few review sites that have one. The reason we like the Ultra-X memory tester so much is because, quite frankly, it’s a memory module’s worst nightmare. This bootable USB device is a relentless, memory pounding animal that will definitely find any weakness or potential problem a memory kit may have. The five passes we like to run can take quite a while to complete depending on the capacity of the kit being tested. It took just over 7-1/2 hours to test this 16 GB kit, and it finished with no errors found.

Ultra-X R.S.T. Stable

Our in-OS testing is performed with a 32M run of HyperPi, which is a great stability test in its own right. We didn’t expect a problem after the kit passed the Ultra-X R.S.T. test, and none were found. Looks like we have a perfectly stable set of memory on our hands!

The Corsair kit was tested using the ASUS X99 Deluxe motherboard, and all the other kits on the ASUS Rampage V Extreme motherboard. Both motherboards were set to use the memory’s XMP Profile, and the CPU was at stock settings for all tests. Given that all the other components used are identical and both motherboards utilize the ASUS OC Socket, results should be consistent between the two different motherboards.

The graphs below show percentage values with the ADATA XPG Z1 2400 MHz (today’s review sample) being the basis and therefore, always 100%. For the scored benchmarks, a higher percentage is better, while for timed benchmarks, a lower percentage is better. Below each graph is a table with the raw data used to compile it.

Synthetic Testing

Our first set of benchmarks come via AIDA64 and its read/write/copy/latency tests. Even though the ADATA kit has the slowest out-of-box MHz rating, it managed to hold its own here and actually top a couple of the faster kits in a few of the tests.

All in all, a great showing for the ADATA kit as it had no problem keeping up with the faster and more expensive kits in the comparison group. Definitely nothing to complain about here.


Overclocking the ADATA XPG Z1 DDR4-2400 MHz kit proved to be simple and quite rewarding. By setting the BCLK to 125 and raising the voltage to 1.35 V, the kit was perfectly stable at 3000 MHz. Incidentally, those are the same settings ADATA’s DDR4-3000 MHz kits are rated at, just as many other manufacturers DDR4-3000 MHz kits are as well. That certainly adds a ton of value to the kit.

3000 MHz - 16-16-16-39 Stable
HyperPi Stable @ 3000 MHz – 16-16-16-39-2T

We wanted to see just how high we could set the speed and get to the desktop to complete a suicide run of SuperPi 1M. By setting the voltage to 1.45 V and the timings to 18-18-18-39, we got to 3250 Mhz. The system wasn’t stable at these settings, but we did manage to complete the SuperPi 1M run.

SuperPi 1M @ 3250 MHz - 18-18-18-39
SuperPi 1M @ 3250 MHz – 18-18-18-39

Returning the memory speed to its default 2400 MHz, we went to work on the timings. About the best we could do here was 13-14-14-36-1T at 1.4 V, which is still pretty impressive. The timings could probably be reduced even more if you’re willing to toss more voltage to the kit, but our results definitely show this kit overclocks quite well on both the the MHz and timings front.

HyperPi Stable @ 2400 MHz - 13-14-14-36-1T
HyperPi Stable @ 2400 MHz – 13-14-14-36-1T


ADATA has a 16 GB kit to be proud of in the XPG Z1 DDR4-2400 MHz. It’s a great performer at stock speeds, but is more than willing to accept pretty hefty overclocks to both speed and timings. Aesthetically speaking, it’s a nice looking kit that would fit in nicely with a variety of different system builds.

The lowest price we found for the kit is $199 at Amazon, which is an attractive price for a DDR4 quad channel kit that can overclock like this. Certainly nothing to complain about on the pricing front.

Excellent performance, terrific overclocking, and an attractive price means ADATA checked all the right boxes with this XPG Z1 DDR4 kit. We have no problem recommending this kit to anyone looking for enthusiast-level DDR4 memory… Overclockers approved!
