How to control voltage on Asus P67 boards

[Cydia]

Hey, I have an Asus P8P67-M Pro board and am currently at 4.5Ghz on all auto settings with a voltage of 1.43v/1.44v. I have absolutely no idea on how to bring the voltage down on these intel cpus. I am used to overclocking AMD cpus through a standard bios, and not using a UEFI bios.

Please can you help me control my voltage output.

I have attached a thumbnail with an image of what I get with OCCT.

You have to set that up in BIOS mate.

Go to BIOS than chose advanced mode and there you will find all you need

Hey raVen, I understand that but I am not sure what effects occur when I disable CPU spread spectrum, or how the offset voltage works. According to the BIOS, my default VCCIO is 1.05v aka default dictated by CPU. I also don't understand load line calibration either. How do I decrease the amount of voltage added under full load. I get 1.06v idle, but at full load it's maxxes out at 1.45v which I know isn't too healthy for my processor.

did you use the Asus Autotune?

 

[Cydia]

No, the only value I adjusted was the turbo multi to 45. I don't want to change any of th voltage setting below since I don't understand how much they will increase the voltage; and accidently fry my CPU. On the AMD boards it was so much simpler.

Take a look at theese guides:

General Asus SB OC guide: http://tinyurl.com/7hqkauw

OC using offset vcore: http://tinyurl.com/6nbmzdh

Edit:

For benching there is no reason to use offset mode, just turn of speestep, EIST ect, but theese can be vary usefull for a 24/7 setup.

So, after reading through these I have come to the conclusion that I need to turn CPU Spread Spectrum to [OFF], and it has brought my voltage down from 1.43-1.45 to 1.36v and it has also brough my temps down (obviously) and for a overclock of 4.5Ghz. Now I just need to figure out how to use CPU Offset to try and bring the voltage down a little bit at a time to see how low I can get it. I am currently running Large Data Set in OCCT checking for errors. Then I will be running Linpack mode with 90% memory and see how that holds out. Or maybe try a higher overclock?

Any tips on what else I can do?

for grins, you should see how the ASUS AI autotune proofs its overclock on voltages to use.

simply adjust manual CPU VCORE to a lower setting. what it is, depends on the CPU. thats

why the autotune can do that for you and then you can analyze the factors. the demo ASUS

uses for its autotune was quite interesting. gave a safe 4.5OC and if you wanted to adavnce

the OC press a button and it'll forward the OC to a tested safe rate.

I cannot specify a manual cpu vcore. The only voltages I can specify in the BIOS are VCCIO, DRAM and CPU OFFSET. I think it may be because I have the matx version of the P8P67 Pro, or atleast thats the only conclusion I can come to.

I will have to have a look as the ASUS AI Autotune, but would rather do everything via the BIOS if possible.

 

[airdeano]

thats noble, but if you could see what to change in the BIOS to achive it.. thatd

be a plus in your favor. then push the limits.. with more overclock.

ps +1 for a fellow Midi owner!

 

[Cydia]

That's very true. Always have had a midi case. Full size are too big, mini too small unless I'm carrying it around. Anyhow back on topic, I'm used to using gigabytes for OC'ing. This is my first Asus board. On my GB I managed a stable OC of 4.4Ghz on a 555BE. But when unlocked could only manage 4.2Ghz because heat then became the deciding factor.

Managed to get 4.6Ghz at 1.4v at the moment too, but seems abit too much voltage for a little increase, need to work out how to bring it down.

I will install Asus AI suite tonight after work. Been looking at 2 new boards too. GA-Z68XP-UD4 or Intel Z77D something, the extreme edition. Any advice?

 

[airdeano]

if your gunna swap a board, then use the new technology. you may not need the new tech, yet, but you'll

be ready in the future. another thing would be pricing. i've been seeing the Z68 stuff kinda in a down

price and thats good but going from a P67 to Z68 isnt really worth the $$ for anything other than video

trans coding. the stats are pretty much the same between P67 and Z68 and even Z77 on the gaming side.

ive got the Z68UD4 and its a fine board, a lil under phased for nasty overclocks the 5 or 7 are stuipidly

stable but are so over the top in price point at the moment.

the only reason for you to level up would be that the performance of the system is lacking in areas

(ie gaming, work related, video photoshop power, etc..) but from your sys specs youve got it, just gotta

master it..

Hey, I have tried using the AI Suite, but it seems useless to me. It managed to get a lower overclock than me, and also it gave me two BSODs. So I am un-installing it and just going to go about it manually.

Unless anyone on here has a P8P67-M Pro matx board and has experience overclocking on it.

 

[Cydia]

Managed to get my voltages to stabilise at 1.34-1.35, but after 55mins of OCCT large data set, core 1 failed. Does it mean I need to increase the voltage slightly?

 

[kilobravo]

Yes try increase a nudge or two.

Have you enabled cpu pll overvoltage?

 

[Cydia]

Yes PLL Overvoltage has always been enabled. I just want to get a stable high overclock, as close to 5ghz as possible.

EDIT: I have disabled PLL Overvoltage and it has given a little more stability to my voltages, now to see by how much and see if I can do 1hr of OCCT Large Set

 

[Cydia]

I cannot get any higher than 4.6Ghz at best. My temps stay well under control at around 63c. I mean I can get into Windows at 5Ghz, but I then BSOD as soon as I go to check the voltage in Core Temp. I see about 1.56v and then BSOD. I cannot even get into Windows at 4.7Ghz, think that is my mystical black hole number. Think I need to get a better motherboard that is designed for overclocking with more voltage control options rather than relying on my CPUs presets.

Sorry about double/triple post. It fails stating CPUTIN breached 95c. It starts off at around 80c when idling and then drops to 30c when underload.

EDIT: Do you think it may help if I remove 1 stick of ram. They are both 4GB sticks.
