Hi all,

I've scanned through most of the threads and cannot find an answer for my question, so here goes...

I recently a new machine and found that the start time during POST is about 30-40 seconds. Is there a way to reduce this?

My current setup:

Asus P6T , Intel core i7 930
Raid 0 (RAID Caviar Black 500gb x 2)
Corsair tri-channel 6gb
Win 7 x64
nvidia GTX 460

The bios is up-to-date. I've disabled floppy. Enabled Quickstart. I have not OC my machine yet. I wouldn't say I'm a noob...but I'm not advance either...

Thanks in advance!

Is this from the time your turn on your PC to you are at the Windows Desktop? If so, it really isn't bad... IMO

One way to speed up any POST, is to go with a SSD, which is still quicker than the RAID setup.

no that's just to start loading up windows. then i see the windows logo..that takes about 30 secs. so total time...over a minute.

I'm not sure if I'm having the same issue, but I just bought a Rampage II Extreme and I also have long post times prior to OS loading.

Seems the initial startup for all the native chipset related items complete and then it goes into a separate JMicron check for whatever IDE or e-sata drives you have plugged into it.

Prior to this board, I've only encoutered Award BIOS versions. This is only the 2nd time I've ever built a machine without it. The AMI BIOS that comes with this board doesn't even seem on par with a great name like Asus.

Spec: Asus Rampage II Extreme, i7 930 2.8(stock) or on a saved profile I created in BIOS for OC to 3.4, 6 GB Corsair DDR3 1600, 6 HDs (3.5 TB total - including 1TB external for backup), Corsair 1000W PS, XP32, XP64, Vista 32, Win7 32, Win7 64, Suse Linux

My Asus P7P55D takes 15 seconds before I see the BIOS post screen. BIOS post screen then takes about 1 seconds and Starting Windows message appears.

During 15 seconds, I guess, CPU, RAM modules, VGA card and Boot Device are checked for physical presence and compatibility. All BIOS settings are at their Default values. I tried to shorten the 15-sec delay by manually assigning values to BIOS parameters but I couldn't.

My Windows bootup time is 36.2 seconds with an OCZ SSD as measured by Windows itself. I have Win 7 x64, Intel i7-860, 8 GB DDR3-1333 RAM and WEI score of 7.2.

I turn off everything in bios that I'm not using.
LAN's (I connect wireless )
IDE controllers ( have all sata drives)
USB 3 off
1394 controller off
All raid controllers ( no raid)
My Timings
Power on, 1 or 2 seconds for display and post.
then approx. 23 seconds until I can open items on the start menu.
SSD gave me a 10 second inprovement when installed.
OC ing to 3.73ghz

have you optimize your registry?
I've done this before but in win xp.. but in win 7, not yet.
from start menu ==> run
type regedit
find setup time
change to 0

Isn't bios on non-volatile memory, so it doesn't matter if you have SSD until it starts loading windows. Is that correct?

@ suat -- you had your bios load in 15 seconds?? was there any other efficiencies you enabled that I did not discover? i know that you're running ssd, but the bios isn't loaded on the ssd...so it shouldn't matter.

@ zipzoomflyhigh -- yeah, i know that I can put it into sleep mode. but i still want a relatively quick cold startup.

@ mhelm1 -- can i ask what your mobo is? asus? i'm current modifying some settings to try and optimize the POST, however everything I have tried has not done anything.

@ tedy81 -- i don't think the registry will optimize POST boot time, I have already optimized windows load time to about 20ish seconds (with RAID 0 setup); I honestly don't think windows would load any faster unless I had ssd...but I hoping I am wrong. anyways, I've tried to look for this setup time...no where to be found on regedit. do you have the path?

My MoBo Gigabyte GA-X58A-UD7

I have just seen where adding a new video card caused the bios to slow, see below:
http://www.tomshardware.com/forum/297069-33-slow-post
What hardware do you have plugged into USB ports and such?
Your Bios times could be from the raid startup. Have you installed the latest chipset drivers for the MoBo?

Yes, I disabled everything not used in BIOS, such as serial port, 1394, Asus Express Gate, JMicron e-SATA/PATA controller, Intel virtualization Tech, Intel C-State Tech, etc.. Still, motherboard takes 15 seconds. I set all DRAM parameters manually. Still 15 seconds before I see BIOS POST screen.

It's looking for something, We just have to figure out what it is!

No, it is not looking for something, I guess. My motherboard has LEDs on it. LED lighting sequence is like this: CPU LED shines for one sec. DRAM LED shines for one sec. CPU LED shines for one sec. DRAM LED shines for ten sec. VGA LED shines for 2 sec. When the VGA LED turns off, I hear a beep sound and then BIOS POST screen appears.

Mabey I was too abstract. When you turn on power the computer does a self test.
It checks out the CPU, (looks at the cpu, looks for the cpu) It then checks out the other hardware it needs to run. ( Chipset, Ram, Video) when it likes what it SEES
It gives you the short beep. if it doesn't like something or SEE something it gives you a beep code telling you what it didn't like.
Do you get my reference: See = Look
It is spending 10 seconds to verify your ram, Start there! I obviously can't see something that it's looking for.

I am sorry I entered all RAM parameters (timings) manually, but it did not help. There are about 24 RAM entries. I set them all manually. No go. Maybe my RAM is too big, 8 GB DDR3. Maybe my BIOS is still looking for something, but I already stopped looking for it. I am ready to test any idea, though.

I have a similar situation. it takes about 10 seconds before I hear a beep sound and see the BIOS POST screen.

@ mhelm1 -- the bios is already updated...so i don't think this is the case. in addition, this was fresh mobo with a brand new graphics.

overall, i somehow think that I won't be able to reduce the bios time... i've incorporated some of the bios settings suat mentioned and no reduction in time...

kn1ght... you are correct... You can't speed up the time it takes a motherboard to begin to "POST" from a cold boot. My EVGA X58 takes 10 to 15 seconds to I hear the post beep, as well. The other items you have addressed with adjustments within your BIOS will help as well. The recommendation of putting your PC in "Sleep" mode will solve this but it does bring about it's own issues within Windows :) 

The reason I recommended a SSD to help decrease the boot time because it take seconds to from the POST screen to the desktop. I've seen a quicker response going through the BIOS with a SSD but it could just have been I've paid attention to this process in the beginning with the SSD. It might always have been that fast??

Gigabyte motherboards may have a short pre-POST time span with Award BIOS. Asus AMI BIOS takes much too long. I am new to Asus. My previous motherboards were Gigabytes and, as soon as I pressed the power button, BIOS POST screen used to come up within at most two seconds.

I finally got an ssd, my boot up time in total is 45 sec (with POST). I managed to shave off a few seconds in post by disabling some items mentioned in mhelm1's post. I must say though, my SSD isn't the newest (OCZ Solid series) -- so it didn't improve my WEI. But the response time and boot has increase significantly! Btw, black viper's modificaitons to services.msc helped reduced some of the windows boot time (boot time is under 25 sec from POST).

Random to the post here... But after installing a non IDE, SATA Blu-ray burner, my AMI bios ASUS motherboard did the same thing as this thread is about, it will complete all checks in 2 sec, and then wait on something for 40 secunds doing nothing, then it will start loading windows. This ONLY happened after i installed a NON IDE. Before i had an IDE optical drive. Now Sata.

You probably have to take a look at a few things to reduce your POST:
- Enter your BIOS (see mhelm1's post) and disable anything that you don't use (e.g. IDE)
- Your msconfig in windows may still be set to 30 seconds on boot, change it to 3
- Look up black viper to disable any unwanted services

Good luck!
