What is the best memory frequency for GA-970A-UD3P with Ryzen Ryzen 7 9700X?

For the Gigabyte GA-970A-UD3P motherboard and AMD Ryzen 7 9700X processor pairing, the optimal memory sweet spot is None running at latency timings of None. This matches standard gear settings (1:1 memory controller clocks), delivering maximum bandwidth and lowest latency.

Does this setup support CUDIMM DDR5 memory?

Yes, CUDIMMs are physically pin-compatible and will fit. However, on this consumer hardware configuration, the integrated memory controller runs CUDIMMs in "Bypass Mode," disabling the clock driver chip. It operates identically to a standard UDIMM module, so we advise against paying a premium for CUDIMMs.

⚡ Gigabyte UEFI DualBIOS Dashboard Instructions

All RAM ships running at stock low JEDEC speeds. To activate full rated None overclock speeds, follow these Gigabyte-specific BIOS configuration steps:

1Tap the "Delete" key repeatedly during the splash screen to open the UEFI dashboard.
2Locate the "Tweaker" tab (on some models, click "Advanced Mode" first).
3Find the "Extreme Memory Profile (X.M.P.)" or "Active EXPO" option.
4Change the setting from "Disabled" to "Profile 1".
5Confirm that System Memory Multiplier is set to Auto (matches EXPO speed).
6Press "F10" to save configs and exit.
