P8Z68-V Pro slow to POST

[snuuggles]

Hey all, I have recently built a system with the following:

Asus P8Z68-V Pro
2500k
8 GB ram (corsair xms 3)
580gtx
Corsair Froce 3 120GB SSD
seasonic x-650 PS

I notice that the system seems to hang when I hit the power button, it takes a good 10-15 seconds for the Asus logo and POST to show. It then sits there for a good 5 seconds and moves onto the windows loading screen - this takes ~15 seconds which is fine, it's really the time before the POST even shows that's a head scratcher to me.

Any ideas? I'll likely flash the MB and GPU at some point, but I hate doing it, so if there are any settings in the bios you can suggest before I do those lmk!

Thanks!

Are you overclocking at all?

First thing I'd try is make note of all your BIOS settings and then do the "Load Defaults".
See if it improves, if it does then slowly put your settings back to what they were and see which one causes the slow boot.

Not if you're using IDE or AHCI mode for your current config that will have to remain the same if you want Windows to happily boot.

snuggles, a few people were having the same problem with their P8Z68-V Pro motherboards at the OC forums: http://www.overclockers.com/forums/showthread.php?t=680382

Apparently, the solution is to disable the "Full Screen Logo" option, along with setting the "Post Report" option to 1 sec. Disabling USB Legacy Support also seems to speed up boot times.

It isn't a few people it seems to be everyone, at least I have yet to come across anyone who isn't having this problem. There are a few tweaks, some of which you have pointed out for reducing the time spent waiting from post until windows begings to load but this really isn't the "main" problem. It is the time taken from pressing the power button until the machine posts that people including myself are becoming frustrated with and there seems to be nothing anyone can do about it.

You can try but i have been through 4 MoBo bios updates and the problem persists.

boot timer....

there is a free version.

I don't know if that is specific to this model board. I have an older asus board- the p5B Deluxe. The same thing happens to me. I think that it has to do with the SATA drivers, the amount of SATA devices, and Intel Rapid Storage technolgy. I bet if you unplugged all of your SATA devices beside the OS drive the problem would go away... try it.

Also, I noticed that this problem got worse when I installed IRST, as opposed to using Windows 7 SATA drivers.

My boot times are from 16 to 21 seconds...(boot timer) and i am running (3) Intel 320's in RAID 0. The above , disabling logo , post report to 1 sec is what i have done. And im sure loading the RAID array takes a few more seconds than not.
Asus P8Z68 deluxe/Gen 3.

This reminds me of my XPlane-9 flight simulator and flying the FA-22 (or other jets). It seems to be a known practice that pilots rev their engines slightly to keep up the wind speed -- in order to land "softly." And there's a lag-time between hitting the throttle and getting a slight boost in wind-speed.

I haven't "TIMED" my P8Z68-V-Pro for switch-on-to-post time, or from post time to log-in screen.

There IS a delay that seems distinct from earlier motherboards and chipsets. First, the rear fan spins up to full speed. After several seconds, the fan spins down (apparently in response to Q-FAN settings). It takes a while to get to the main post screen. I have "logo" turned off, and if there's some extensive RAM test in the mix (I can't remember) I turned that off, too.

But the board -- and the system -- are reliable. Maybe others are experiencing longer delays. If I can find my stopwatch, I'll post my measurements here . . .

i have the same board and proc and the same issue. It will also just hang after the RAID loads. Very annoying.

Sorry for the delayed update. I actually forgot I had created this post and was googling for a solution to this. Found my own dang post.

Anyways, I've mostly solved the problem by turning off almost everything I didn't completely need on the Onboard Devices tab. I'm afraid I didn't think to write down the specific things I have turned off, but I can say for sure that what didn't help (because I had already tried turning these off and continued to have the symptoms):

- USB legacy support (2 and 3)
- Marvell Storage Controller
- HD Audio controller
- 1394 controller

Again, non of the above helped. After I turned off one of the following, my symptoms are way reduced:

- JMB Storage controller
- Intel PXE OPROM

I'm pretty sure one of those was the culprit.

Just to be clear:

- before: hit power button, fans start etc, but black screen for ~15s. Then Bios (mem test) appears and everything basically flys from there. So this 15s of blank was the issue. I never had any issues after I saw the bios for the first time.
- now: maybe less than 5 seconds before I see the mem test. Not immediate like my old MBs, but not horrible.

I hope this is helpful to someone, I was not OCing or RAIDing. Just a single SSD connected to the intel 6.0GB channel. I even tried disconnecting everything but the KB and monitor and I still got that delay. One of those two things I listed above was causing the problem as far as I can tell.

I believe it's the JMicron controller for eSATA. if this is left enabled it basically does a 2-boot cycle.

i read something similar months ago on overclockers.net forums.

Also double boot is easy fixed by setting "keep current" in Bios under boot menu and then "Option Rom messages" .

Enabling either or both of the two controllers -- the Marvell and/or the JMicron -- will indeed delay system post. I noticed this while I was initially setting up my system -- to enable only those things I was planning to use frequently or right away.

Not everyone. I've been running this motherboard for months without any of your described issues. However, I always disable full-logo and usb legacy support.

I'm having the same issue - 16 second delay before ANYTHING comes on the monitor after hitting the power button.

Snuggles, I tried disabling everything to know avail. These other fixes helped with POST time (went from 7 to 4 seconds), but my initial delay is still ~16 seconds, with fans turning on and off before output is sent to the monitor.
