The H61 mainboard supports the following cpus:
< br >
Celeron G1620, G1630, Pentium G2030, i3-3220, 3240, i5-3450, 3470, i7-3770.
< br >
The corresponding CPU slot is of the LGA1155 type and can be used by any processor of the corresponding interface type.

The CPU interface supported by the H61 chipset is LGA1155, so the fourth generation core i5 and i7 is impossible to support, only the second and third generation i5 and i7 can be installed, but the i5 3570K is some waste, H61 does not support overclocking, it is recommended to i5 2500 or i5 3470 on the line.
