Hello Seagrey, thanks for joining the Intel Community.
Based on the motherboard information, you will be able to use an I7-3770 since it is compatible with it. However, the motherboard supports memory up to 1333 GHz.
Please check the information available in our site http://ark.intel.com/products/50098/Intel-Desktop-Board-DH67BL
The use of memory out of specifications will decrease the lifetime of the unit and it could generate damage.
Thank you Sylvia for your reply.
Yes I've checked the compatibility informations but I had a doubt about the BIOS since I couldn't find such informations in the release notes.
So the maximum supported RAM frequency for the DH67BL is 1333 even with the latest BIOS and 3rd Generation CPU.
All right and thanks again.
That is correct Seagrey, the memory you should use is 1333 MHz.
