Test Rig
For our tests, we used our Test Rig which consists of a Gigabyte Z790 AORUS PRO X motherboard, along with an Intel Core i9-14900K and a GeForce RTX 4080 SUPER graphics card.
One thing to take into consideration is that not all motherboards will take higher capacity ram, so be sure to check the QVL list on the motherboard’s website, and also update the BIOS to the latest version. You also need to be aware that some motherboards may not support memory speeds above 6400MT/s… in most cases, 8000MT/s is the maximum that can be stabilized on AMD and Intel motherboards.
* ALL tests are conducted at specified default speeds and settings.

Installation
The memory modules slotted in nicely on to our Gigabyte Z790 AORUS PRO X motherboard with no issues at all. Remember to installed them on DIMM slot A2 and B2 to enable quad channel mode. Please refer to your motherboard manual for more information.
BIOS Setup
To get the ram to run at DDR5-6600 speeds remember enable XMP 3.0 Profiles. Just select the XMP Profile 1 and the BIOS and “Save” and that’s it! No more messing around with voltages or memory timings. 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 3300 MHz which gives you the default speed of DDR5-6600. It also supports AMD’s EXPO and Intel’s XMP 3.0.
The other thing you’ll notice is that the ram is now running in Quad channel mode (4 x 32-bit). 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 Viper Elite 5 TUF Gaming RGB DDR5-6600 48GB Memory Kit uses memory chips produced by SK Hynix. CAS latency is reported at 34-40-40-84 operating on a voltage of 1.4V, which is one of the lowest we’ve seen.
