AMD EXPO Explained - New Memory Overclocking Standard

by Hilbert Hagedoorn on: 08/31/2022 09:21 AM | source: | 4 comment(s)

Together with the new AMD Ryzen 7000 series motherboards and processors, AMD used the occasion to introduce AMD EXPO, a new technology.

AMD EXPO is a technology that is comparable to or equivalent to Intel XMP, also known as Intel Extreme Memory Profile. This protocol lets you overclock (tweak) DDR5 memories to achieve peak performance with a single click.

According to AMD, 15 DDR5 kits have already been verified for AMD EXPO, indicating they are 100% compatible with Ryzen 7000 and AM5 motherboards. After selecting the option in the BIOS, they will automatically apply the frequency adjustment profiles and the times, using values that have already been validated as stable for that memory. Memory capable of reaching 6400 MT/s will be available at launch, while AMD claims that kits with latencies of 63 nanoseconds will be available. Despite the announcement of additional support, AMD will continue to support XMP profiles, allowing DDR5 memory configurations that have shown to be stable to be used within the Intel protocol.

AMD EXPO will be available alongside the Ryzen 7000 on September 27, as well as the X670 and X670 Extreme motherboards.

well the 7nm apus can do up to ~2400 with enough voltage, I think its safe to say that it will clock higher than that with a 6nm i/o die.

what got to with if/infinity fabric maxing out at 2000mhz and being at 2-1??? makes u wonder if they ever can use 8000mhz ram unless u can go 4-1 later

The desktop only chips (5900x,5800x) ect top out at 2000fclk since the I/O die is 14nm, the 7nm apus (no I/o die) (5700g/5600g ect) can do 4800mt/s with ddr4 in 1:1 mode (2400fclk) and > 6000mt/s in 2:1 mode( limited by the ram).

presumably the zen 4 chips can do more than that because they use 6nm i/o die(similar to the apu) ,I don't think amd will need 4:1, even for > 8000mt/s
