Asrock x370 gaming k4 and max mem clock

   Remember, Ryzen is nit-picky concerning memory.

All ASRock MBs now state 3200MHz is supported. Supported, not guaranteed, as much rides on just what memory you might be using.

	I really don't think the max memory supported speed is 2933MHz. Like you said even the B350 support 3200MHz

	You may be able to run 3200MHz even now, even with dual rank sticks. But it'll be hard to get it stable, and quite possibly it'll be slower than a good 2933 setting at this point. As others said, the platform will have to mature and the hopes are on AMDs next AGESA update.

	For any Ryzen board, maximum memory speed is a function of support in the UEFI/BIOS. At this point, that is in the hands of AMD and the code updates they provide to mother board manufactures for use in the UEFI/BIOS. The specs may simply be a case of the X370 GK4 being at the low end of the X370 model boards. But the main reason may be the specs just haven't been updated. Given the state of Ryzen memory support from the memory manufactures, and the results I have had with memory supposedly designed for Ryzen (3200 memory that won't work above 2933), the memory speed specs are not guaranteed limits or even guaranteed to be reached. Memory support and compatibility is the biggest issue we have with Ryzen at this time, for any mother board manufacture. Memory that uses Samsung B-die memory chips has the best chance of working at 3200, but the memory model better be rated for at least that speed. Ryzen is not a mature platform at this point. CPU microcode updates from AMD are still being provided to mother board manufactures, one is known to be coming some time in May.

	I asked ASRock Tech support this very question over 3 weeks ago. Lets hope they answer. Even the B350's support 3200.

	I'm really interested in this board, seems almost perfect to me, except for the memory speed: it seems to be one of the few boards not supporting memory speeds up to 3200mhz. Why did you decide to support only up to 2933mhz and are there any plans to add support for 3200mhz on this board in the future?
