Everytime I try to overclock the cpu it just keeps Reverting back to the default 3000gz, all other settings are accept just fine but not the Cpu. I have updated the bios to its latest version but again no success.

any ideas?

What settings are you using to get over stock speed? Are you just increasing the multiplier? Any voltage increases? Also, do you have XMP enabled? If so, I'd set your RAM back to 2133 defaults, as OCing can be affected depending on memory frequency and CPU Strap being used as well.

so these are the settings I change

Your voltages are similar to mine. I do have my input Voltage at ~1.91V though, with LLC on 8. Maybe try adjusting those. If that doesn't help, just to try it, maybe reset CMOS and try the 5Way OC in AIsuite III. Also, are you using the 100, 125, or 166 strap for CPU? Is your PCI-E at 100mhz as well?

 

[sihall69]

Using the 125 strap and yes PCI-e is at 100mhz, tried your settings and no different, also just installed and tried the 5way oc in the ai suite, but when it restarts I get the 'overclocking failed'message and have to restore bios defaults to be able to boot the pc up again.

 

[1LiquidPC]

OK, I'd try a few things to narrow things down. I'd leave the RAM at stock 2133 for now to narrow down RAM speed as any kind of problem as anything over 2133 is technically overclocked. I would try to OC using the 100 strap instead of the 125. It's known that some CPU's just don't like any other strap than 100 for OCing, while others work fine. Leave uncore at 3000 as well. Also, for reference, 2400, 2666, and 3200 RAM frequencies play nice w/ the 100 Strap and have trouble w/ 125 to my knowledge, while 2800 and 3000 don't, though some have better luck than others. Another thing, though I think your using manual voltage already, is that Adaptive voltage only works on the 100 strap, vs Manual for all of them.

Tried those settings but to no avail.

I assume the yellow text are the results the settings should yield, but after saving them and restarting the cpu will not budge (hardware settings on the left)

 

[1LiquidPC]

Your are correct. The Yellow text is what it "should" be if everything goes to plan. My X99 Deluxe UEFI is very similar to your Rampage. Since your trying to boot to 4.2Ghz, and that doesn't work, have you tried something lower, even 3.5 or so. If you can try 3.5, try lower volts as well as I've read to much can cause problems as well, maybe 1.25V Can you budge at all from the stock 3.0ghz frequency? Are there any other OC related settings you adjusted in UEFI other than the boot order, ect? Turbo itself isn't disabled or anything I'm guessing. Also, your not the only one I've seen in forums w/ the same problem, some people can't OC at all regardless of settings. BTW, what Q-Code are you seeing on your board?

 

[1LiquidPC]

I forget to ask about a good bit of other settings, just remembers this morning. Are you using speedstep/c-states when trying to overclock? If so, try disabling since your using manual voltage. This can be argued as this is considered old school, but I still see conflicting ingo on whether this is needed or not. I'm using this method myself. Also, do you have CPU Current Capability raised to 140% instead of stock 100. Even with increased vcore, you still need this limit raised. Also, set CPU Power Phase Control to extreme. CPU Switching Frequency to Auto, VRM Spread Spectrum to Off. Also, turn Active Frequency mode to Off. Of course LLC to 6 or more though I think you adjusted that already. Hopefully this will help.
