As far as I know AMD forced daisy chain for all X570
MSI is usually running daisy chain and Asus on X470. I don't expect any change there. MSI has been making all the memory records on Intel lately as well.
X470 Pro Carbon holds the X470 record right now at 2032MHz (4066MHz effective CL20) on water in terms of MHz: https://hwbot.org/submission/3973686...ram_2032.1_mhz
Crosshair VII Hero has had ~2GHz (4000MHz effective CL18) at 60°C (i.e. not LN2) https://hwbot.org/submission/3956314...sdram_1995_mhz
Asrock supposedly has T-topology on X470 Taichi per techpowerup guide https://www.techpowerup.com/reviews/...g_Guide/4.html
However, on X370 they had some of the best memory overclocking since the Crosshair VI Hero was also T-topology and the TI NexFET powerblock for memory VRM is just outright better than what other vendors were using.
Generally Gigabyte has had the worst memory overclocks on their midrange due to the T-topology unless you run 4 DIMMs. People have gotten 3400-3600 regardless of this. I've seen someone over on hwbot get 1900MHz
(3800MHz effective , C18) on their X470 G7 at 62°C CPU though (i.e. not LN2).
If you're buying in anticipation for Ryzen 3rd gen, AMD states that 3600C16 is the "sweet spot" for Ryzen 3rd gen and that over 3733MHz runs the Infinity Fabric at 2:1 ratio which is suboptimal for latency.
In other news it looks like the X570-P is as I expected , it looks to be 10x powerstages for VCORE which is weaker than the 12x used on ~$10-15 more expensive TUF Plus:
60% (6 of 10) are on the main VRM heatsink whereas 7 of 12 (~58%) are for the TUF so it's relatively equal
As a comparison for the lower midrange: The X570 Steel Legend has all 8
on the main VRM heatsink , MSI Pro carbon has 6 of 10 on the main VRM heatsink as well (60%) but theirs is covered in plastic bits and is using Dual-N fets instead of powerstages, and Aorus Elite has 9 of 12 (75%) on the main VRM heatsink
B450 Pro Carbon had all 8 sets of mosfets on the main "extended" VRM heatsink , the new Gaming Plus / Edge boards have it split 6 on the main VRM heatsink and 2 on the SOC VRM heatsink.
