Introduction

Silicon Power (SP) is a Taiwanese hardware manufacturer founded in 2003, with a wide range of consumer and industrial products. In the consumer market the company is known for providing high-quality flash storage.

Silicon Power currently offers an assortment of memory products ranging from laptop and server solutions to the newest technologies and consumer products like DDR5. Using the well established DDR4 Zenith product line, Silicon Power updates their product, reusing the name and design for the DDR5 iteration. Available with RGB, and without; configurations include 16 GB (2x 8 GB), 32 GB (2x 16 GB) and 64 GB (2x 32 GB) kits with frequencies ranging from 5200 MT/s to 6000 MT/s.


In this review, we will be taking a closer look at the Silicon Power Zenith RGB DDR5-5600 memory kit. Equipped with modest timings of 40-40-40-76 operating at 1.25 V for the 5600 MT/s X.M.P profile. This memory is well-suited for a wide range of computers due to a lower operating frequency which is ideal for a truly hassle-free experience for both AMD and Intel-based platforms. Marketed towards a wide range of users, we will benchmark this this Silicon Power Zenith RGB DDR5 32 GB kit and see how it stacks up to the competition, along with some overclocking as well!

Specifications

Packaging

Silicon Power Zenith RGB DDR5-5600 memory comes in a blister pack, which is quite uncommon to see in the western market, but it does provide excellent protection from scratches and theft prevention to a degree. The front of the packaging shows the memory branding (Zenith RGB) along with the rated XMP (DDR5-5600), DIMM configuration and RGB software support for ASUS, Gigabyte, MSI and ASRock. The back mentions that this memory supports the latest Intel XMP standards and guarantees compatibility in multiple languages. One crucial missing component is information relating to the applied XMP timings and voltage. This is generally found on the back of the packaging / barcode or visible on the memory DIMMs themselves. Unfortunately the sticker placed on the memory itself is on the opposite side and cannot be seen without opening the packaging.

A Closer Look

Silicon Power Zenith RGB modules are available in white and black. The sample we received is the white version, Having both variations for consumers to choose from allows Silicon Power to support different types of themed computer builds.


Silicon Power puts the XPOWER signature brand logo in the bottom center on the heatspreader. In the top right corner both sides has "DDR5 GAMING MEMORY" written.


On one side of each DIMM module is the identification sticker listing the SKU, rated XMP operating frequency. This are lacking critical information such as full XMP timings and the applied voltage. It is not necessary to have since the SKU is listed, which can be used to look up the details on Silicon Power website. This is just an inconvenience for those that handle a lot of memory on a daily basis.


Laying the DIMMs on the side, you can see the XPOWER logo in the center, along with "DDR5 RGB" written in the corner.


The Silicon Power XPOWER Zenith RGB DDR5-5600 kit weighs in at 44 grams on my scale. For Z-height, it is 39 mm rounding up with my calipers.


After taking the heatspreader off, we see that these are single-sided DIMMs with eight 2 GB ICs. This is as expected for a DDR5 32 GB kit since densities increased with DDR5. The thermal pad covers all the memory ICs. This particular kit does not have any coverage for the PMIC and surrounding components. On the back of the PCB is where the RGB LEDs are located.


A closer look at the ICs shows that these are SK Hynix (H5CG48MEBDX014). Currently, Micron, Samsung, and SK Hynix are the three suppliers of DDR5 ICs. When it comes to overclocking, the general consensus is that SK Hynix does provide the highest frequencies, scales better with higher voltage and has the ability to offer low primary timings that are equal, if not better than the rest. The newly released SK Hynix A-Die can go even further. The kit we have here today is using M-Die, which is the predecessor, but is still quite good in regards to overclocking. In fact the timings can go a bit lower versus A-Die, but the modules can't clock as high in frequency and require more overall voltage for similar timings and configuration.


With DDR5, one of the major changes is how the motherboard directly provides 5 V to the memory module's PMIC, which is then stepped down and split accordingly. No longer is the motherboard responsible for regulating the voltages, as with DDR4. The PMIC has the part number "0D=8KJ4N." Software reports this as Richtek being the manufacturer. Internet investigation provides no additional information.
