Hello,

I have a 2009 cMP, updated to 5,1 using a Vega 64 gpu running Sonoma using OCLP 2.2.0. For some reason it is now booting VERY slowly. The boot picker screen is barely on the screen. If I extend the boot picker time out to 30 seconds, it does show up, but VERY slowly appears on the screen and they keyboard is not responsive when trying to select a drive. If I hit it a bunch of times, it will move, but it takes alot to get it to move.

Any ide why this is happening? I tried looking for other posts, but didn't see anything.

Thanks!

You failed to mention how your cMP storage is configured, e.g. how many drives? is your boot drive HD or SSD? Very detailed description of your system components and configuration will yield more and helpful responses.
 
I’m using a SABRENT Rocket Q 1TB NVMe PCIe M.2 SSD in a RIITOP M.2 NVMe to PCI-e adapter. Currently it is the only storage device in the system. I did have a SATA SSD with my original Mojave OS on it, as well as a Win 11 SATA SSD. This set up used to boot fine, until recently.

Once the slow boot issue started I removed both SATA drives, wiped the NVMe drive, and reinstalled Sonoma and OCLP, the issue persists. It also did the same thing when booting off the OCLP Sonoma install thumb drive.

If I remove the NVMe drive and reinstall the Mojave drive it boots fine.
 
Did you tested with another drive? Try Sonoma with one of your SATA SSDs.
 
Good idea! I just finished doing a Sonoma install on a new SATA SSD in drive bay #1, it's the only drive in the system, other than the USB install drive. It's doing the same thing.

EDIT: I also should mention I used the latest (2.3.1) OCLP for this install.
 
Things that I'd do:

  1. check if any diagnostic LEDs are lit,
  2. check the CPU tray if any of red LEDs near the DIMMs sockets are lit,
  3. check the RTC battery voltage with a voltmeter/multimeter, replace it with a new BR2032 if the voltage is below 3.00V (do not use a CR2032, different chemistry from BR2032 that will cook overtime with the GPU heat),
  4. deep reset the NVRAM,
  5. run AHT/ASD to see if you find any clues.

If after all the basic maintenance is done and the same behaviour happens, I'd try Monterey instead of Sonoma.

Thank you for this! The issue ended up being something with my RAM which ASD reported. I swapped out the 128 gb of RAM and installed my old 64 gb set and it's booting up beautifully.

Thanks again!

You'll also notice the more ram you have, the longer it takes to boot.
