MPG Carbon WIFI Intel Z790 DDR5 boots rather slowly

Hey everyone,

I have recently built a PC with a MPG Carbon WIFI Intel Z790 DDR5 board that boots rather slowly, compared to a second PC I have with a similar configuration. Let me explain:

Second (slightly older PC):
MSI MPG Edge WIFI Intel Z690 So.1700 DDR5
Intel Core i7 13700K
32GB (2x 16GB) Corsair Vengeance DDR5-6000 DIMM CL36-36-36-76
12GB Gigabyte GeForce RTX 4070 Ti Gaming OC
1TB Kingston KC3000 M.2 PCIe 4.0
1000 Watt be quiet! Pure Power 12 M

This PC boots up almost instantly. In just over 10 seconds from pressing the power button, I'm in Windows. I used this PC for general purpose and gaming, but now I want to use it mainly for music production, which is why I bought a new PC without a dedicated GPU and just switched the 4070Ti from the older PC to the new one.

Now this is the new PC:
MSI MPG Carbon WIFI Intel Z790 So.1700 DDR5
Intel Core i7 14700K
32GB (2x 16GB) Corsair Vengeance DDR5-6000 DIMM CL30
12GB Gigabyte GeForce RTX 4070 Ti Gaming OC
1TB Kingston KC3000 M.2 PCIe 4.0
1000 Watt be quiet! Pure Power 12 M

This PC boots up comparatively slowly. it takes over 40 seeconds from pressing the power butoon until I'm in Windows. As you can see the configuration is very similar. The Ram is slightly different (CL30 vs CL36), the CPU is better and of course the motherboard is different. The BIOS settings of the two boards are also identical (I've also tried stock settings of course).

Further information:
The "Last BIOS time" in Windows Task manager shows round about 9 seconds on BOTH PCs. However, on the newer PC with the z790, the boot process remains much longer on the motherboard bootlogo with the while circle scrolling than the older PC with the z690.

Does anyone know what the issue might be? From researching I found quite a lot of people with slow boot times on this board. However, I find it hard to believe that the z790 is so much slower to boot than the z690.

Any help is appreciated!

Since you mention the RAM, can you do a test where you use the RAM from the old PC in the new PC?

BIOS is up to date (latest stable version)? ASMedia SATA chip is disabled, see here?

Thank you for your reply!

BIOS is fully updated. ASMedia SATA chip was enabled, I didn't know about issues there. I disabled it, but it didn't change anything. I thought about switching out the ram, but it's a bit of a project, since I don't have my music production PC in my house =/.

But I did peform a memory check and it gave me no errors, so I believe the RAM is fine. If i ever get to it, I will try testing the RAM.

What are the best / fastest settings for Memory Training. It's currentlly set to auto.

EDIT: Disabled XHCI Hand-Off and set USB Legacy support to Auto --> no change

And how about using just one RAM module in slot A2? Just trying to see if the RAM is a factor, as best we can without trying the other RAM.

This sounds to me like it's a Windows issue since the BIOS times are identical. Try starting it in safe mode and / or disable everything possible at startup and see if it helps.
 
Hey everyone, I haven'f had the chance to test the RAM, yet, but soemthing weird happened today. The mainboard failed to initialize the GPU. The debug light remained white which means some kind of GPU error if I understand correctly.

This has happend once and other than that, the GPU functions properly.

Does anyone know why a GPU issue would occur on the z790?
 
The VGA LED can sometimes be misleading, it can hint to a drive problem for example. Read out the SMART data of the Kingston with CrystalDiskInfo. In the program's menu under "Function" -> Advanced Feature -> Raw Values, select "10 [DEC]" to have human-readable values, and you can press CTRL-S to save a screenshot.

Then, do you have a spare SSD you could do a test installation of Windows to, taking out the Kingston SSD of course, to see if the boot times are suddenly much faster?
 
I think the NVME is fine:

The VGA error just happened again, though ... =/

While I'm in Windows there is no problem. Just sometimes while booting / restarting, I think.
 
Hmm yeah, looks alright. The very last entry looks quite high, but then again, they might be mundane log entries and nothing critical.

This would be a good time to start swapping parts around and seeing if it behaves "normally" at any point all of a sudden. Then you have your culprit. The RAM kit, the GPU, all could be switched for a quick test. Theoretically also the SSD, but i don't know how Windows activation takes it when you swap the hardware from under its butt, even though both systems are activated. So i would at least disconnect the network when trying that.

One thing you can do without any parts swapping: Take off the CPU cooler, take out the CPU, and check for bent pins in the CPU socket, which can easily happen from some mistake during CPU installation. Also see here and the following posts. The pins all have to look completely uniform under light, like rows of soldiers. See if there are ones that look different from the rest, and if so, take some photos, upload to https://imgbb.com/ for example, and link them here. Now, i know it works perfectly once it gets past the long boot times, but any weird, inexplicable problems, it's not a bad idea to rule out bent socket pins.
 
I've found out that the reason might also be that the PCI Max Link speed is set to "Auto" in the BIOS. What setting is the correct one for my Motherboard and Card? Is the 4060Ti capable of Gen5 or should I choose Gen4 or 3?

According to CPU-Z, "auto" chooses Gen4 or am I wrong?
