Test Rig
For our tests, we used our Test Rig which consists of an Z790 PG SONIC motherboard, along with an Intel Core i9-13900K and a GeForce RTX 3090 graphics card.
* ALL tests are conducted at specified default speeds and settings.

Installation
No issues during installation. Just make sure you align the notch to the DIMM slots on the motherboard and insert firmly.
Please take note, as I’ve said before DDR5 ram is not compatible with DDR4, the notch on the memory module is positioned slightly different.
BIOS Setup
To set the default speed of DDR5-6000 using XMP 3.0 Profiles. Just select the XMP Profile 1 and the BIOS and “Save” and that’s it! All other settings were left untouched on AUTO.
CPU-Z and SPD Information
As you can see from the CPU-Z screenshot, the ram supports both EXPO and XMP 3.0. The DRAM frequency is running at 2992 MHz which is correct for the default speed of DDR5-6000. The other thing you’ll notice is that the ram is now running in Quad channel mode. Here’s a quick reason why … DDR5 gives you two 32-bit wide (40-bit wide, with ECC) channels per stick, which means that you get a quad-channel configuration when running two DIMMs.
AIDA64 Memory Information
The SPD information on AIDA64 shows that the Lexar ARES RGB DDR5-6000 uses memory chips produced by SK Hynix. A high CAS latency is expected when running DDR5 ram. CAS latency is reported at 34-38-38-76 …
Full Load Temperatures
Load temps reached a high of 61 degrees Celsius which I was a suprise to see. I was expecting something much lower. Having said that, we didn’t encounter any issues. The heatspreaders seems to be doing an adequate job of cooling the ram.
