HELP!!! Cannot overclock FX-8350 on Asus Crosshair V Formula

As the title suggests, I'm unable to overclock. I'm taking this guide as reference

http://rog.asus.com/216552013/crosshair-motherboards/guide-overclocking-fx-8350-to-4-8ghz-on-crossha...

I am unable to do the first step where you need to change the CPU Ratio. I cant change it. Its set to auto and when I try to change it, it wont change. I click on enter but nothing happens. Its as if the cpu ratio option is greyed out.

Can you suggest what I should do?

Hi tremonade and Welcome to ROG

Not sure where your at with your OCing.
Best to use D.O.C.P initially with system selected settings, then do a stress test for stability.
You can then tune for performance.
In Extreme Tweaker menu, Do you have AI Overclock tuner set to manual.
Change by keying desired OC ratio in manually using CPU ratio field.

Hi. Thanks for yor answer. I just had to enter the number in that box. I was pressing enter on my keyboard instead. I feel embarrased now.

Hi tremonade and don't be embarrassed, Its usually the most obvious that has us stumped sometimes.
Don't forget too that some values in Bios will only be accepted using the + and - Keys.
Thanks for reporting back.

Hello. One more thing, I use the Corsair H100i Cooler, but the temps I get under idle(without OCing) is 42-43 Degrees Celcius. Don't you think it's high considering the fact that I'm using a liquid cooler?

You mean the BIOS temps? IIRC, those arent idle temperatures---you have to go into Windows for that, so that you can read the temps in C6 state (idle throttling) and/or core parking. Try CoreTemp, you can get it free online.

Hi. I overclocked it to 4.6Ghz with Voltage at 1.42V. The temp im getting on load after running prime95 for 15 mins is 68C. Is it normal or is it high? Tj max is shown as 90C in coretemp.

Hi tremonade
Temps at 4.6GHz are acceptable if a little high at 68C under P95 on small FFT, if that was your test.
Now raise your multiplier to 24 for a 4.8GHz OC ,Key in static CPU voltage to whatever is shown in Bios, and test again.
If successful, What are your temps now?

Hi. I am currently running at 4.6Ghz with 1.375V with max temp 63C. I cant get to 4.8Ghz. I tried different voltages, starting from 1.42V upto 1.5V. But the system crashes once i start the prime95 test. So I guess my chip can only handle upto 4.6Ghz.

68C is a bit high for that low a voltage/speed...for example, with the H110 and the voltage hitting 1.53-1.57 under load on my 9590, the temps never get that high. Now, that H110 is a bit better than your H100, but it shouldnt be THAT much of a difference. Make sure you have the fans pulling in fresh air from outside the case, not pushing air out or pulling air from inside the case.

If that is all good, you may need to clean and redo the thermal paste/grease.
