A Closer Look

The KLEVV CRAS XR5 DD5 is only available currently with white heatspreaders and a Intel XMP memory profile. Besides a color swap and a slight name change, the DDR5 version closely resembles KLEVV DDR4 CRAS XR memory with a unique Circular light bar at the top, glossy black strip below and the textured heatspreader to give it that signature brand recognition. Plans for AMD EXPO kits or other colors have yet to be announced by KLEVV.


Across the glossy black strip is the product name and DDR5 written in white. Both sides have this text.


On one side of each DIMM module is the identification sticker listing the SKU, rated XMP operating frequency, corresponding voltage of 1.30, and XMP related timings. KLEVV keeps the information in an easy to read format, which is great for those who aren't that tech savvy and will have a hard time deciphering a block of text into something useful.


Laying the DIMMs on the side, we can see this isn't the standard RGB lighting setup. Instead of the entire top being illuminated, the center is blacked out, leaving just the outer ring for RGB lighting to be seen.


The KLEVV CRAS XR5 DD5-6200 Z-height is 43 mm after rounding up with the calipers and weighs in at 60 g on the scale.


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. Upon closer inspection, all LEDs are on the opposing side of the PCB.


A closer look at the ICs shows that these are SK Hynix (H5CG48MEBDX014). Currently, Micron, Samsung, and SK Hynix are the three big 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. This of course greatly depends on the IC quailty too.


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=98M4B." Software reports this as Richtek being the manufacturer. Internet investigation provides no additional information.
