If you plan to push the OC limits, you'll want to have the current V1.90 BIOS and the V1.80 BIOS on a flash drive so when the system hangs and the BIOS goes into a "stupid loop" you can install the other BIOS and then switch back to V1.90. Otherwise the system will not actually make the BIOS changes you set. If you're not pushing to find the highest CPU/RAM OC then you won't need this option.
If you are running RAM @2133 MHz. or higher then you'll need to contact Asrock about a modded if you desire to increase the CPU-NB above the default 2200 MHz.
While the BIOS will allow you to change the settings, it doesn't actually make those changes with BIOS V1.90 (and possibly earlier BIOS versions) when the RAM is run @ 2133 MHz. and higher.
You will find when stress testing under P95 or similar with an overclocked, over volted 8-core FX processor that the VRM circuit will cut in and out if the VRM overheats. This is to protect the VRM circuit from burning up. This will only occur in stress testing when you run the test for longer than ~45 minutes with good CPU cooling. It will happen sooner with low CPU cooling.Edited by AMD4ME - 3/6/13 at 12:01pm
