Test Rig
For our tests, we used our Test Rig which consists of an ASRock Z790 Taichi Lite motherboard, along with an Intel Core i9-13900K and a Radeon RX 7900 XTX 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. Also make sure you install these modules on DIMM slots A2 and B2 of the motherboard.
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. Also please read this article on How to Install Your DDR5 Ram Correctly (in the correct slots) in Order to Run XMP Mode.
BIOS Setup
To set the advertised speed of DDR5-7600 using XMP 3.0 Profiles. Just select the XMP Profile 1 in the BIOS and “Save” and that’s it! All other settings were left untouched on AUTO.
I was quite surprised to see that our test rig booted up flawlessly, and loaded straight in to Windows without any issues whatsoever. Not many motherboards can do this. The ASRock Z790 Taichi (Lite) seems to work great with these memory modules.
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 3800 MHz which is correct for the default speed of DDR5-7600. 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 Patriot Viper Xtreme 5 DDR5-7600 uses memory chips produced by SK Hynix, which are known to overclock very well. CAS lastency is reported at 36-48-48-84 … a high CAS latenct is expected when running DDR5 ram.
Full Load Temperatures
Load temps reached a high of 52 degrees Celsius which seem a littl high. I was expecting something a little lower. But having said that, the heatspreaders seems to be doing an adequate job of cooling the ram. So all good. During our tests, we didn’t encounter any issues whatsoever.
