Hi all. Got this retro build for some old games I picked up at a charity sale. Changed cpu 3.00ghz clock speed in bios to 3.1 to test. Pc does not post on first attempt then after 2nd time does boot into Windows but clock setting is ignored. Any ideas? No other settings changed. Would have thought vcore or anything else would be ok on default settings to achieve 3.1. Temps, benchmarking, ram, gpu....all good.
