Test Rig
For our tests, we used our Test Rig which consists of an Z790 PG Riptide WiFi motherboard, along with an Intel Core i9-14900K and a Radeon RX 7900 XTX graphics card.
* ALL tests are conducted at specified default speeds and settings.
| CPU | Intel Core i9-14900K |
| Cooling | Thermaltake TH360 V2 Ultra ARGB AIO |
| Motherboard | ASRock Z790 PG Riptide WiFi |
| Ram | Lexar ARES RGB DDR5-7200 32GB Memory Kit |
| XMP 3.0 profiles | YES |
| SSD | Lexar NM800 Pro 2TB PCIE Gen4 NVMe |
| PSU | Gigabyte UD850 – 850W Gold PSU |
| VGA card | Radeon RX 7900 XTX |
| OS |
Windows 11 |
Installation
Remember, DDR4 ram is NOT compatible with DDR5 ram. So make sure you install them on motherboards that support DDR5 ram only. No issues during installation. Just align the notch to the DIMM slots on the motherboard and insert firmly.
BIOS Setup
To set the default speed of DDR5-7200 using XMP 3.0 Profiles. Just select the XMP Profile 1 and the BIOS and “Save” and that’s it! All other settings in the BIOS were left untouched on AUTO.
CPU-Z and SPD Information
As you can see from the CPU-Z screenshot, the ram supports XMP 3.0 only. The DRAM frequency is running at 3591 MHz which is about right for the default speed of DDR5-7200.
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 DDR5-7200 uses memory chips produced by SK Hynix. CAS latency is reported at 34-42-42 operating on a voltage of 1.4V.
Full Load Temperatures
Load temps reached a high of 57 degrees Celsius which is as expected for the higher voltage and faster speed.

0000 Thank you
Hi,
Could you please share the full timings report of Extreme memory profiles. I’d like to see how it looks with the profile for 6400 for the 7200 module.
Thanks in advance.
