I increased the overclock of the i5 4690k to 4.2ghz stable at 1.200v and achieved 4.6ghz stable at 1.365v on my Asus H81M-Plus. Why do folks keep saying you can't overclock these boards when mine does? Here are some links for reference:
Uncertain about the source of the warning, it's clear the H81M-Plus can be overclocked, as confirmed by even the ASUS highlights. AI Suite 3 offers "supervising overclocking" on this board. Other H81 variants might not support it, which likely explains the information you received.
RealBeast:
Unclear who said you can't overclock the H81M-Plus, since it's common knowledge the H81M-Plus can be overclocked. Even ASUS mentions this. AI Suite 3 lets you "monitor overclocking" on that board. Some other versions of the H81 might not support it, which likely explains the confusion. Trust me, search online for "overclocking on a h81 board" and see what others say. It's generally accepted that K series chips work well, except for higher-end models like i5 4690k and i7 4790k, which usually need a Z board to be overclocked.

Unclear who gave you the idea that you can't overclock since it's widely understood the H81M-Plus can, even ASUS mentions this.

Some other versions of the H81 might not support it, which is likely why you heard that.
I'm not sure why it specifies a 3.5ghz base clock and a 4.4ghz turbo clock.
Nick_120 shared some insights about overclocking on the H81M-Plus. He mentioned that while some sources claim it can't be overclocked, others suggest it is possible, especially with certain boards like AI Suite 3. He noted that some versions of the H81 might not support it and that higher-end chips usually need a Z board for full performance. He also warned that not all online information is accurate and recommended checking reliable sources.

I'm not sure why it lists a base clock of 3.5ghz and a turbo clock of 4.4ghz—that's not correct. Rely on CPU-Z, not just the graphics card details that just copy from the CPU info.
I changed many settings but it still stays at 4.4ghz all the time, never dropping below it—it feels like it's stuck in turbo mode, which is strange because I need 1.25v. It really bothers me.
I changed many settings, but it still stays at 4.4ghz all the time—it never drops below that, which is strange since it feels like it's stuck in turbo mode. It’s weird because I have to maintain 1.25v. You can’t just tweak a few values and call it done. You need to adjust gradually while monitoring temperatures and voltage. The best approach is to start a separate thread for overclocking to fine-tune your settings.
