    Posted: 23 Sep 2015 at 12:49am
Hi,

I have a complete new System with
- Z170 Extreme6+
- I7 6700k
- 16 GB DDR4
- 256GB Samsung SM951 M.2 2280 (running OS--> Windows 10)
- GTX 970
and some other harddisks...

The Problem is, the system takes about ~20 seconds to boot  which is far too much in my opinion, because the windows boot itself is nearly instant.
most of the time it spends during the ASROCK-logo and I don't have any clue where to search for a solution.

All drivers are up to date. Also the bios is on the newest version(1.40 updated with asrock app-shop) and I activated ultra fastboot in bios. The System isn't overclocked.

I don't knwo if this has anything to do with but
in the beginning some times I had the problem my pc freezed during booting (just a black screen the pc won't even start but fans were running), and I had to reset.
this also happened during the last bios update and I had to recover the Bios from the back-up bios to make my PC work again...
but but after the recovery I updated the bios again and everything seems fine since then, except the boot duration.

Would be nice if someone can give me some hints.

Thanks

You described the situation perfectly. You even included the reason in your post.

POST is relatively long, and actual OS loading it extremely fast. Those two things, POST and OS loading, are affected by different factors.

Your answer to the situation is, "and some other harddisks...". If they are really spinning HDDs, they take time to get going, several seconds (5 - 8) and POST checks each one, and waits for them.

Older mother boards used to have delay times you could set in the BIOS to wait for HDDs to get going, up to 30 seconds. SSDs spoil us with their instant start up time, HDDs are another story.

Unplug one or more of your HDDs, and see how long your startup time is. One of them may be particularly slow. I've seen this issue in the other ASRock forum several times.

In case you don't know, the UEFI/BIOS update cleared any settings you changed in the BIOS, unless you redid them after the update. So the Ultra Fast setting may be gone.

I am running into a similar issue with this mainboard.
The post time increased from just under 5s to 8s when I updated from BIOS version 1.2 to 1.4.
Going back to 1.2 solved this issue.
 
I reset and reconfigured the BIOS setting to the exact same ones for both versions.
 
Has anybody tried version 1.5?
 
I am hesitant to just try 1.5 since the upgrade also resets the ME config and thus the fTPM which makes me lose important settings in the OS like virtual smartcards.

The description for UEFI version 1.50 is:

1. Improve DRAM compatibility.
2. Improve OC function.
3. Add NVME Configuration.

NVMe is Non-Volatile Memory Express. The NVMe configuration is for the new NVMe SSDs that are beginning to be available.

Is the ME you are talking about related to NVMe, or is ME the Intel Management Engine firmware or software?

If it's the Management Engine software, then you have nothing to worry about. Or do you know that the ME firmware is also updated in 1.50?

I don't have your board, so I can't comment on UEFI 1.40 being slower to POST than 1.20. The ironic part is the description for 1.40 is:

1. Improve boot time.
2. Update Microcode, ME, RC.
3. Improve DRAM compatibility.

"Improve boot time" might also include the POST time, which you say is slower now. Did you notice any new options in the UEFI that might cause the slower POST if not configured correctly? Did you use the Fast Boot option with UEFI 1.20?

I see that UEFI 1.40 includes an ME update. That is not the same as the NVMe configuration update in 1.50.

Or did you just type the wrong version number?

The ME is the Intel Management Engine firmware which is also responsible for "creating" the firmware based TPM 2.0.
 
Post time increase significantly from 1.2 to 1.4 and I ensure 100% that all setting were correct. There were no additional settings in 1.4 that should impact post time.
 
Would love to hear from others on their experience.

I just did some more test and installed 1.5 as well.
 
Post times from power off are:
 
BIOS 1.2: 5.2 sec
BIOS 1.4 & 1.5: 8.1 sec
 
I tested this with HHD and with SSD only and get the exact same times.
The SSDs used are an SM951 AHCI as boot and an Intel SSD750 as data drive. The HDD is a WD Black 1GB (again I disconnected it for the tests).
 
BIOS 1.4 and 1.5 are much slower for my config in terms of post (despite 1.4 claiming an improvement).
 
What are other seeing in terms of post time?

So you consider 2.9 seconds as "much slower" for your configuration? The Intel 750 is known to be a slow starting or long POST device. Users are complaining about that in many forums.

If your POST time increased by three seconds after adding an Intel 750 SSD, you are very lucky. Normally it is much longer than that.

What was added in the UEFI for NVMe configuration in UEFI 1.50?

So UEFI 1.50 does nothing with the Intel ME, as I said.

Hi Parsec,
 
I am not sure that you read my posts right.
 
I am keeping the config the same (including the SSD750 and all BIOS settings).
1.2 is about 3 sec faster than 1.4 & 1.5. 3sec is close to my complete OS boot time of just under 5 secs, so YES, I think it is something Asrock should consider investigating.
 
Modern UEFI firmware has good instrumentation and it should be relatively easy to understand which UEFI driver is causing the delay. It's certainly not the ME firmware as a downgrade to 1.2 keeps the new ME version.

The 750 just received a firmware update specifically addressing slow boot times.  Not sure if it will help in your system if you're not booting from it.

Thanks a lot. I am not booting from it, but still did the update. Smile
