ASUS P8P67 Series Overclocking Guide and Information

[fmkenner]

I have the Asus P8Z68 Deluxe board and the BIOS looks like its the same. Could I use the same methods for my board? I'm sorry if its a dumb question, I'm just now jumping into the game and trying to learn to do it myself. I had someone help me get to 4.5Khz, and its stable, but it would be nice to know how he did it. I'm also curious what my CPU/MB will do. Thanks in advance.

Hi i was just wonder if pll overvoltage is safe, i can OC to 5ghz with HT off...but was wondering if its safe to use the pll overvoltage and will it cause degradation

Yes use PLL Overvoltage for any Multi over 47. Once enabled youll probably be able to lower the CPU voltage a little bit.

Most recent BIOS update and ASUS Suite2.

Just bought my new mobo and cpu and am having issues OCing. Previously had Sabertooth 990fx so Im familiar with the UEFI BIOS.

CPU without touching the voltage just DIGI+VRM is stable at 4914mhz for 10min in Prime95 with max temp of 61deg. Which is great! But. Any higher and I get a hard crash of BSOD. Which is fine. But I can not manually set my voltage and want to have that ability but also to go higher with my OC and see what my chip can achieve. Everytime I set the voltage, whether it's with the offset or manual setting in the BIOS or in ASUS Suite2 my mobo is giving my CPU more volts than it should. If i set it to 1.4 it gives it erratic numbers like 1.68 or higher and it BSODs. (by the way I'm checking and monitoring my voltage and temps with ASUS Suite2)

So this brings on the question, why is my mobos voltage setting not working? Why when I set it to a certain value (which should be a simple task) does it give my CPU more or too much voltage and crash my computer? Why does it not set at 1.4 when I set it at 1.4?

Somebody please help.

Try setting what you need via the BIOS rather than AI Suite II. It could be to do with the LLC setting that adds voltage to compensate for vDrop under load. Sometimes a combination of lower vCore + high LLC or visa-versa works, depending on the chip and system.
