ASUS P8P67 PRO REV 5v surging to 7.8v - Page 2

post #11 of 16
Did you actually read the 5v rail with a multimeter?

Also, at 4.6GHz and 1.36V you're probably not going to notice much of a difference. Just experiment when you get the board. What I noticed from less VRMs and lower quality ones is that once you get over a certain power limit the voltage swing gets large (which limits overclocking).

 

I'm simply going off what DeXel said, I heard the vrm's weren't actually half bad on this. Board will be here in a day or two, I'll get the chip to 4.6 or so and if the VRMs get hot then I'll just throw a case fan blowing air on them in there. Curious to see where the overclocking wall is on this thing, with my PRO I could not get past 5Ghz no matter how many volts I threw at it (Could've also just been the chip's wall as well) I will post my findings here thumbsupsmiley.png

On the power supply? Or a voltage reading point on the motherboard? I have a multimeter at the ready so I'd be willing to try that. Is it possible that the 5v reading could somehow be 'stuck' at 7.8v? I tested both powersupplies on a friend's rig and they were working fine which confirms it's the motherboard atleast. I found a buyer for the TX650 as well so I will keep the SeaSonic unit for it's modularity (that a word?) Cheers! Hope you guys don't mind my asking all these questions redface.gif

don't count phase quality in the phase count, that is just ridiculous because there is no specified quality for phases, just pretty easy to meet minimum requirements.

Pro has 12 phase VRM design doubled from 6 and it's digital.

Extreme4 has 8 phase VRM design doubled from 4 in a weird way (not every mosfet has a driver), and it's analog.

Moreover, mosfets used on Asus board are much better than Extreme4. In fact, you won't find Asus and Gigabyte (and few others) using that type of mosfets on any of their current boards for VRM except maybe the low end, non-OC boards.

You can check this list made by Sin0822 for more info thumb.gif.

Well then I probably will rma my PRO and then have the E4 as backup. In the meantime it'll do me fine just for a light overclock and some folding. Thanks for all the help guys, greatly appreciated! +rep

Folding really benefits from high clocks though. Would be ideal if you could get your 2500K at 4.8GHz+
