A Closer Look

Once the memory is out of the packaging, we can get a closer look at the Lexar THOR memory. Currently, only sold with Matte Black heatspreaders, it does not have any RGB elements to speak of either.


The name "THOR," along with the pattern design, gives the impression that it is taking inspiration from Norse mythology. Thor, the thunder God, along with Mjölnir, the hammer. The patterns on the sides are a nice addition, though once installed into the computer, they will no longer be visible.


On one side of each DIMM module is the identification sticker listing the rated XMP operating frequency, corresponding voltage of 1.30, and XMP / EXPO related primary timings. Lexar does not have the SKU number printed directly on the memory, which could be a point of confusion for those trying to look up more information without having to install the memory modules.


Laying the DIMMs on the side, we can see that these do not have any RGB elements and the top is also completely void of any text.


The Lexar THOR DDR5-6000 Z-height is 40 mm after rounding down with calipers and weighs in at 55 g on the scale.


After taking the heat spreader 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 coverage for the PMIC and surrounding components, but the lower voltage of 1.30 and a lifetime warranty will put at ease those who are concerned about component longevity.


A closer look at the ICs and Lexar covering up the actual vendor with its own silkscreen. Currently, Micron, Samsung, and SK Hynix are the three big suppliers of DDR5 ICs. CPU-Z tells us this is SK Hynix and, from overclocking, these are the A-Die revision. Though, because Lexar (Longsys) is rebranding these, this could be different from batch to batch.


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 "0P=AFKG1." Software reports this as Richtek being the manufacturer. Internet investigation provides no additional information.
