Red Hot RAM

With the launch of Intel’s X99 consumer-grade hardware, production of DDR4 memory has ramped up quite a bit as gamers and enthusiasts look to build hardcore PCs built for overclock and gaming. The impending arrival of Intel’s Skylake processors also make this an opportune time for memory manufacturers to start cranking out their offerings, much like how ADATA has with the ADATA XPG Z1 DDR4 RAM sticks.

The kit that we received from ADATA is a 4GBx4 kit, which gives us 16GBs of DDR4 memory, and whilst the kit does stat that it runs at 2,400MHz, this particular feature needs to be unlocked using the Intel Xtreme Memory Profile, which can be accessed via your motherboard’s BIOS page.

One of the XPG Z1’s claim to fame is its cooling performance, which in turn should help out when users begin to experiment with overclocking the RAM. This particular set features a 10 layer PCB with 2oz of copper that reduces electric resistance, hence consuming less power. This, coupled with the XPG Z1’s red-coloured cooling fins with contoured designs symbolises ADATA’s pursuit for extreme performance.


At stock, it’s operating voltage is set to 1.2V, which is quite low as some of the DDR4 memories we’ve seen so far are usually set to either 1.35V or 1.5V. Overclocking is one of the XPG Z1’s stronger suits, as ADATA claims as under the right circumstances, it should be able to clock up to 3,333MHz.
And overclocking the RAM without tinkering too much with the voltage and latency numbers isn’t too much of a hassle either as we managed to get it to run at about 2,800MHz with no issues.

We’re fairly certain if you can manage to tweak and experiment with the numbers even more, you should also be able to breach the 3,000MHz mark.
Another compelling feature about the XPG Z1 is that the kit comes in several varieties, including a variety of sizes, ranging from 4GBx2 to 4GBx4 kits to ones that have speeds of 2,133MHz right up to 3,333MHz right out of the box.

CHIP CONCLUDE: The ADATA XPG Z1 is an excellent memory set that should satisfy the cravings of an overclocker a fair bit, thanks to its low voltage requirements and overclocking headroom that allows even the lower speed kits to be boosted up a fair amount.
