Review: GeIL EVO X DDR4-3200MHz CL16 2x8GB Memory Kit



The GeIL EVO X memory kit ships in a compact and colourful cupboard box with the front dominated by a beautiful image of the memory module illuminating in red colour. While there’s a GeIL logo on the top left, you can also see words on the top right saying that the memory kit is thoroughly tested with GeIL’s own DYNA 4 SLT tester for maximum compatibility and reliability. Below it is the product name followed by two badges to the left indicating that the memory kit supports ASUS’s Aura RGB and MSI’s Mystic Light Sync lighting technology with the compatible RGB motherboards from both companies. Under these badges GeIL highlights the key features of the EVO X series, which are the sliding hot-switch RGB mode change, compatibility with motherboard’s RGB UI software, and GeIL’s Hybrid-Independent-Light-Module (HILM) technology.



On the reverse side, you will find a window that reveals the label sticker of one of the memory modules inside. There’s also sticker next to it that indicates part number and specifications of the memory kit so that you can do a double checking. Above it is a picture of the blue-illuminated EVO X memory kit sitting on the ASRock Z170 OC Formula, the same motherboard that we are going to use in this review. To the right is the product name, followed by information about the package content, and GeIL mailing address and official website. Across the bottom, once again you can see the DYNA 4 SLT sign, alongside two badges indicating the health and safety standards and the country of origin which is Taiwan.

Inside the retail packaging, you will find the two memory modules in which each is well protected in an individual transparent blister pack. Also in the box are an installation guide as well as a pair of 12V RGB power cables and a fan power cable.

In terms of documentation, certainly GeIL has provided the most comprehensive installation guide ever for a memory product. Inside the guide, GeIL explains in more details regarding the Hybrid-Independent-Light-Module (HILM) technology as well as the procedures on how to use the sliding hot-switch and software control by the motherboard RGB UI utility.



Looking at the memory modules themselves, the GeIL EVO X looks stunning and most probably one of the best looking memory kits that we have ever seen so far. The first thing that you will notice is that the translucent light bar that’s spanning across on top of the memory modules. There’s also a translucent EVO X logo that will illuminate when the system is powered up. Next would be the black heat-spreaders which cover full length of the PCB to provide a huge area of heat dissipation and keep the temperature as low as possible. The heat-spreaders are made by pure aluminum to protect the PCB from bending while forcing the memory modules into the memory slots. The PCB used comes in matte-black colour that looks very nice and neat in any setup.

Standing at a total height of 60mm, GeIL’s EVO X series has emerged as the tallest DDR4 memory modules that we’ve ever seen so far. It is significantly taller than Kingston’s HyperX Predator DDR4 and Corsair’s Vengeance LED DDR4 memory modules, both have an overall height of 55mm. The extraordinary height could lead to incompatibility issue with some large CPU coolers in the market. Good thing is that the EVO X memory can still fit well under our massive Noctua NH-D15 cooler that offers up to 64mm clearance in single fan mode.



Flipping over to the other side of the memory modules, it doesn’t look as aggressive as the front, without any EVO X logo but just a barcode sticker containing technical specifications of the memory kit. These include the model name, model number, part number, operating voltage, and the country of origin which is Taiwan. Both modules come with the same serial number so there’s no way to distinguish them from each other.



You can also see a red-coloured sliding hot-switch at the top of the memory module, which allows you to select the LED colours in a choice of Red, Green, Blue or RGB cycle.



Conforms to the DDR4 standard, each module is made by 288 pins of gold contact fingers. Like any other DDR4 memory module, the GeIL EVO X also features golden fingers in a slightly convex shape with a cut-out on the middle.

Each memory module features a 4-pin 12V RGB header that is compatible with motherboards supporting ASUS’s Aura RGB and MSI’s Mystic Light Sync technologies. For instance, the ASUS ROG Rampage V Edition that we’ve reviewed not long ago is fully compatible with this feature in which you can control the RGB LED lighting via the Aura software.

For motherboards which doesn’t have the RGB header, fear not as you can use the 3-pin 9V/12V Y-power cable and connect it to the fan headers on your motherboard.



The heat-spreaders make contact with the memory chips by a piece of adhesive pad on each side. As usual, we used the hair dryer method to dismantle the heat-spreaders from the PCB. Once the heat-spreaders are pried opened, we saw a single-sided PCB with only one single side of the PCB containing the memory chips.



There are a total of eight memory chips on the PCB, each marked CG4L1GM88BA093A1. Each chip is 1024MB giving a total capacity of 8,192MB or 8GB. According to the GeIL representative that we’ve contacted, the chips are actually manufactured by South Korea-based SK-Hynix which is one of the world’s largest memory chip manufacturers.

Aside from the main PCB, you will find a tiny board that is responsible for controlling the RGB LED lighting. The RGB PCB sports a switch that is then connected to the red sliding hot-switch on top of the memory module.

Putting everything back into the out-of-the-box condition, we tested the RGB LED lighting featuring GeIL’s HILM Technology. Since our ASRock Z170 OC Formula motherboard comes without the RGB header so this is the only way to power up the RGB LED lighting. The illumination results turn out to be impressive with the single-colour mode worked flawlessly. Somehow when we switched to the RGB mode, it appears that the LED colours from two memory modules didn’t sync perfectly between each other. Apparently this is the common weakness if you use the power from the fan header, the lighting is not easy to be synced. It happens simply because of the controller IC located on each memory module has its own frequency. In contrast, if you’re using the power from the RGB header, there won’t be such issue because the RGB header will have signals which tells the controller ICs on the modules when they should blink in what colours.
