Resolved cMP 2010 pre-chime lag?

[Zeke D]

So, what's up with the pre-chime lag with my cMP 2010? it's like 20 seconds until chime.

:02 - Power on
:22 - Chime
:36 - Login Screen
:47 - Desktop
:52 - Helpers/apps loaded

2010 Mac Pro 5,1 (140 bootROM)
2x Xeon HC X5670
32GB Samsung RAM (4x 8GB)
Samsung SM951 128GB in a generic 4x PCIe adapter (slot #3)
MSI GTX680Ti 2GB
OSX Sierra 10.12.6

Samsung SM951 128GB in a generic 4x PCIe adapter (slot #3)

This most likely....

If it’s your boot drive, then Definitely... It’s a known issue, had it myself...

Just for grins, put it in slot2 and see if it changes.

EDIT: Now that Lou has chimed in, I’m pretty sure the delay I was thinking about came AFTER the chime. Soooo, no clue. Sorry.

Just did mine - SM951, AHCI, 512GB. - 11 secs. Mine is in Slot 3!

Come to think of it, Lou. The delay I’m thinking of comes AFTER the chime. Good catch.

Here are mine...

It's my understanding that the chime is an audible signal that your system has passed Power On Self Test (POST). This is test of the essential components to make sure that the next step, including booting the OS, can occur.

Part of that is a memory test. The more memory, the longer the time before the chime. If I understand this correctly, try taking some memory out and see if the POST time is reduced.

My total boot up time is now longer once I went from 8 to 32 GB, and put a boot disk on a PCIe card.

You are correct.

That makes sense. I'm running 32GB, and before I was running 8GB. I guess a cold boot time of ~40 seconds will just have to do...

I have 48GB and the cold boot delay is substantial due to self test.

 

[startergo]

Uuh, mine is high and I am at 128GB RAM...
BTW isn't there a verbose switch for troubleshooting?

CMD + V

Hold down these keys while booting, but if you don’t have an EFI GPU you see the output.

Mixing memory can give a long delay before you hear the chime.

I went from 2GB 800Mhz RAM, and added 6GB 667Mhz RAM, and that gives me a really long delay, as the system has to read the ram types, set all the ram to 667Mhz, then do the other ram test stuff for POST, then I hear the chime.
