I have solved the asus cold double boot problem

[blackened23]

So some asus motherboards have a problem where, if you do a cold boot, it will boot/fan spinup and then do it again. Ergo, cold double boot.

I found that disabling the marvell sata controller in the bios removed this problem for me. I use my SSD's on the intel ports so, if you're using fewer than 2 SATA 6gb/s drives maybe this will help you.

This is on the asus p8p67 motherboard, I hear it affects the P8z68 as well.

I know you're not a noob. I had seen forum posts elsewhere with people puzzled by the P8Z68-V-[Pro/Deluxe/etc.] behavior. And of course you would know the boards have their own TPU "processor" and EPU which manage the clock settings and voltage regulation . . . I'm not sure exactly what they do when switched off.

So when I cold boot, the fans fire up full throttle, then the system almost seems to go dead until the keyboard etc. initialize. I've noticed that changing clock or BIOS settings may have the board go through a couple cycles of this.

I think some people expected it to work according to their experience with LGA-775 or socket-478. These boards seem much more stable than for prior generations, but some processes [like unhinging the ISRT cache drive] can take long enough that a user can panic and hit the reset button (as I did last week).

The only time I've ever had the system lock up so I really needed to hit that reset button was with BSOD's during the over-clocking process. And of course, "reset" doesn't solve that problem all the time.

I just suspect that some folks see the board behaving in unexpected ways, and jump to conclusions about it.

No such issue on my P8Z68V-Pro and I have the Marvell SATA controller enabled for my DVD drive.

This is a well known problem specific to the P8P67 boards that asus has admitted to. I guess the Z68 boards aren't affected.

Basically what happens is if you cold boot, your fans will spin up and then your PC will turn off and cycle through 1 more time. The PC works fine, but just double boots on cold boots.

It didn't really affect my daily use because my system is fine...just drove me crazy that every cold boot was a double boot :awe:

I got this same exact issue on on my Asus p8p67 pro.

Hardly ever have it down so hardly a issue but once in a while i'll get a failed oc error on the auto oc it does and i have to reset it and put it back and it will be fine for a while.

Overall a nice board still iv'e never had issues with asus and this as a first for me is forgivable.

This was also a problem BITD on P35 chipset boards. I had an Abit IP35-E and it was a huge issue back then. AFAIK it doesn't hurt anything, but people flipped out over it. Deja vu with these Asus boards.

You think that was bad? How about a Gigabyte K8N51GMF-9 (damn, old Gigabyte mobos have hilarously cryptic model naming) that takes a dozen PSU power cyclings to make it cold boot, but works perfectly fine as long as you don't cut the AC power to the PSU.

This is all very reassuring to me! My Gigabyte board sometimes does not finish its first cold boot (when it happens, it always fails to detect the second harddisk at POST, and then never finishes the "Verifying DMI data...", doesn't get to the bootloader), and I have to hit the case's reset button, then all is well.

At least now I know it's not so strange AND is not even an intense problem at all.

Still sounds a bit like my very routine and familiar Z68 reboot. Maybe it's a more subtle variation. All I can say -- without firsthand knowledge of P67 -- is that these boards are much easier for handling / recovering from unstable over-clocks. Since the Z68 brings in the best of P67 and one other chipset as a sort of "hybrid" -- it's entirely possible that they DIDN'T iron out this or that quirk. I can't say. Maybe we "think" it's a quirk, but it wasn't meant to be . . . . Can't say definitely about that, either . .
