The G.Skill Ripjaws V F4-2400C15D-32GVR 2x16GB, being a part of the newest mainstream performance DDR4 line from the company, utilizes a set of medium profile heatspreaders. It is designed to draw attention with its sharp red color scheme, and styled with a more traditional, mid to late 2000's stance. The Ripjaws V's aluminum pieces are distinctively shaped and molded to give it a little more visual flare and complexity. Aluminum is lightweight, and serves as a decent heat conductor, while the ventilated heatsink design improves air ventilation for faster heat dissipation (Although it is probably more for style in this particular application). The Ripjaws V is only about one centimeter taller than modules with no heatspreaders at all. This is useful for systems equipped with side mounted CPU heatsink fans adjacent to the memory slots, as it can piggy-back off the generated airflow. Since the heatspreaders' height is relatively moderate, it is still entirely possible for the Ripjaws V to fit under a well-designed cooler with sufficient clearance room. Whether you like to call it marketing gimmick or whatnot, it is almost impossible nowadays to find performance memory without any form of a heatspreader attached, haha. They do undeniably serve a purpose in dissipating heat, but for most memory modules, unless run at a voltage significantly over designed voltages -- which you will not, special thanks to integrated memory controllers on Intel processors -- this feature is certainly not a requirement. But I will admit they look pretty cool in any windowed chassis.
The heatspreader design of the G.Skill Ripjaws V modules is symmetrical when looked at straight on and also symmetrical between sides, which is fairly logical, because memory ICs reside on both sides of the slick black PCB. Besides functional purposes, it also improves the look. The company's logo is printed directly onto the red plastic piece at the top, while the full product line branding is printed onto label near the middle of one of the main faces. Meanwhile, a specification label is placed on one side of each module. It lists the kit name (F4-2400C15D-32GVR), frequency, latencies, bandwidth, voltage, and the module's memory capacity. The serial number underneath the bar consists of a long string of numeric characters; the last digit is consecutive to the value listed on the other module to indicate that they come from the same box. Our particular unit was manufactured in February 2016.
As you can see more clearly in our photo above, the G.Skill Ripjaws V F4-2400C15D-32GVR 2x16GB has a very nice black PCB. Meanwhile, its heatspreader is composed of two separate metal components, which are aligned two interlocking clips at the top. The heatspreader is held to the module itself by a strip of thermally conductive adhesive. The adhesive force between the two heatspreader and memory ICs is not particularly strong, but if you ever do take them off, keep your hair dryer around for a safer procedure.
From our above photo, it should also be clearer on how the heatspreaders are designed. It slopes up from both sides, and flattens out and bevels down about one-third of the way in to create a simple arch shape. A series of slots are methodically cut into the aluminum pieces in order to improve ventilation, as well as increasing visual complexity by creating distinctive lines. Since the pieces are made from thin aluminum, it does not hold a lot of heat, therefore dissipating the heat energy relatively quickly into the surrounding environment. In the end, if you are going to be pushing your system to the limits with high memory voltages, the heatspreaders may be beneficial to improve system stability and overclocking potential (But you probably will not, thanks to Intel as aforementioned). On the other hand, you may need to remove them if it does not clear your processor heatsink, the fact that the RAM will function just fine without the heatspreaders is something to keep in mind.
A closer look at the memory chips on the G.Skill Ripjaws V F4-2400C15D-32GVR 2x16GB dual channel memory kit. The photo above should be quite clear -- it says "K4A8G085WB" on each IC. These are Samsung manufactured chips, with eight 1GB chips on each side for a total of 16GB on each DIMM. They are identical to the ones found in the Patriot Viper Elite PC4-24000 2x8GB I reviewed last year, except the Viper Elite is single sided. As mentioned on the previous page, these RAM modules run at a frequency of DDR4-2400 with 15-15-15-35 latencies. They operate at a stock voltage of 1.20V, which is below the Core i3/i5/i7 maximum safe limit of 1.35V. Here is a table of specifications for the ICs, as obtained from Samsung's website:
