I use 1502
hmm..try setting vccio to 1.12-1.16
And as for that pll lowering stuff..Hogwash.Set it to around 1.77-1.845
Read this guide.Written by someone@Asus..not a guy who thinks he knows it all on OCN who I'm not naming atm.
Having actually reached 5GHz with a 2600K, that advice isn't the best.
There's no reason to disable Turbo. That has been proven to have no effect on an OC's stability.
For my processor, I had to lower my PLL voltage to 1.625 in order to get it to work. At higher PLL voltage, I was unable to get my computer to stress for more than a few hours. Given the high variability in the different voltage settings required to reach a stable 5GHz, I strongly recommend that you test each and every PLL voltage setting. It's time consuming and a pain in the ass, but I would never have reach stability if I hadn't. Both of the settings +/- one step are not as stable as 1.625 on my mobo at 5GHz.
I agree with the VCCIO voltage recommendation, but again, what you're looking for is stability, not voltage overload. More volts =/= more stability. In fact, your stability problems might be because you are putting too much volts in right now. Not necessarily that it is
the solution, but that it might be.
If you haven't, head over to the so-called "know it all" munaim's Sandy Stable Club (see sig link). Other than totally not being a know-it-all, Munaim's generous advice helped me (and countless others) get to a stable OC.
The hard forum guide isn't bad, but to follow it blindly wouldn't have given me the results I got. Like I said, there's a lot of settings that each have a lot of options, so read all the advice you can get, and figure out what works for your
CPU. Unfortunately, there isn't a one-size-fits-all solution, and not all processors can do 5GHz stably. If you have questions about any OC settings, the Sandy Stable Club thread is a great place to ask.
