roco_smith 7003 Bios apply to my CH6Extreme , so far the best Bios working on my motherboard , very stable 1800X oc to 4.0GHZ with offset mode , I notice a drop on my cpu temps compare to the previous one

Most C6H top out mem around 3466MHz (with stability) while from what I've seen more C7H users are able to stabilize 3600MHz or slightly higher for every day use.

C7H has XFR2 but I have not seen any substantial higher every day OC's using it compared to my 2700x/C6H running PE3 OC with a 101.8 Bclk. 4275MHz all core, 4428MHz single/multi with memory running 3466MHz C14. It also has a second NVME slot.

The C6H is known for many to have sensor reading issues (granularity) but is easily corrected by offsetting values in SW (etc HWinfo) when compared to manually probing the Probelt Points with DMM.
This has been my only issue with the C6H and TBH it's not that big of deal.

If the budget allows go for the C7H, but if Ryzen 2 is not in your future and funds are currently tight yes the C6H would be fine.

I'm still happy with mine, well at least for two more weeks Come on 7-7-19

Some differences between the boards:

  • C6H has AM3 cooler mount holes, C7H has not
  • C6H has 2 more SATA ports, C7H has one more NVMe but it takes PCI express lanes from the PCIx16 top slot
  • Different layout (bottom vs top) of the internal Start/Reset on board buttons
  • No PS2 port on C6H and C7H has one (useful for W7 install)
  • C7H has slightly better thermals on a slightly more efficient VRM

I'm running C6H and those 2 extra SATAs are useful, also running 4x dimms, never had an issue with the board, thermals working fine.

None of these mobos is a bad choice. Performance wise are the same, also neither will get PCI-x 4.0 seems like.
Thank you for all information!
Before ask here, the differences that I noticed was about better memory clocks and slight better VRM (10+2 phases X470) compared with (8+4 phases) on x370.
Know all my questions are solved! Thank you so much for so detailed informations

I'll try find one used, probably will be better than I need and the prices are very good!
