Hello everyone.
I have a PC of the Microstar brand, with an Intel I7 6700 mounted on the following motherboard, a MEDION H110H4-EM, and the BIOS is the following, AMERICAN MEGATRENDS INC. 110EMW0X.102 from 04-03-2016.
1. Can you tell me if this board is ATX, microATX, etc.? I want to change the cabinet and I don't know which to choice
2. I would like to know what is the most current BIOS that exists to install it and where to find it, in case you think it is interesting to change it.
3. I would also like to know until which DRAM frequency I can install for optimal operation, I currently have running an 8mb slot at 2133mhz.
Thank you very much for your time and answers.
