Built and OCed 3x I7 - 7700k gaming rigs (4.9-5.2ghz)
Posted: Mon Jan 30, 2017 2:20 pm
I was rebuilding my home pc (CPU/RAM/Board/SSD), a friends (CPU/RAM/Board/SSD/Case), and another full build for another friend. Was able to boot at 5.3ghz, but not stable above 5.2ghz, setting a personal best ghz record. Then backed each chip off 100mhz for long term stability, followed up with a 24hr test. Figured I would share my results and some pics!
