Yes, a strong VRM and motherboard are essential for memory overclocking.
Yes, a strong VRM and motherboard are essential for memory overclocking.
I watched the GamersNexus video on the new i3 10100 and i5 10400, plus a test comparing RAM speeds for AMD CPUs. It looks like fast RAM really does matter for the CPU, no matter the brand. Would you think a budget motherboard—like the base model of an overclockable memory board such as the Gigabyte B450 DS3H or the Asus B450 Prime—can perform well in that way?
Lower-end boards offer reduced performance. The GB DS3H is extremely poor; steer clear of it.
