I currently have a 7950x3d and the post times are 1 to 2 minutes which has annoyed me over the last 2 years.

Currently upgrading/side grading to 9850x3d due to not doing any rendering anymore.

Current specs are

7950x3d
64gb 2x32gb 6400 cl32
X670e tuf gaming
1x 2tb nvme
3x 4tb nvme
4090 strix
1600w corsair psu

I also understand that running 4 ssds is causing my 4090 to run at 4x and not 16x.

Strangely when it was built I never flagged this bit with quick dirty OC I was faster then most 4090 scores well over the peak would I gain more with a x870e motherboard ?

Thoughts and opinions please :)
 
If you want fast boot times with DDR5 you have to look to Intel really - though as above with Memory Context Restore enabled on AMD it significantly improves the situation but it isn't necessarily a fire and forget setting and on some systems will never be stable.

Running x4 instead of x16 on a 4090 would also cause noticeable increase to game load times, despite not necessarily impacting in game performance, and a hit to some specific games (around 20%) which hit the PCI-e bus hard.

Off the top of my head I believe the Gigabyte Aorus boards have the quickest boot times on AMD on average compared to any other brand or model, but that may differ with different configurations. (EDIT: Hard to find many benchmarks for it but there is a brief mention here https://www.techspot.com/review/2900-amd-x870-motherboards/ ).

which motherboard, running 4 NVMe will not impact GPU in primary slot, unless you have an add in card in secondary x16 slot then it will drop to x8.

If you have accidently enabled bifurcation on primary slot then you might get it on x4 but that'd be the only reason.

I have never experienced a slow boot (though slow probably needs a qualifier, it is certainly not in the minutes) on my Gigabyte board out side of first training.

I have slow shutdown but that is probably because I have not done a fresh re-install since Windows 8 despite many hardware changes :o :D

Ahhhh thanks for that, 17-30 seconds would be happy with that. Atm it takes about a minute before I even get the 1st bios screen

Look through my mobo and gpuz yeah its running at pcie 2.0 16x or 4.0 at 4x

Ran a full suit of benchmarks and some are good and excellent some are very poor.
 
Thanks for you help it looks like the only mobo that will allow 3 nvmes and full 16x slot are the high end Asus 1x to the cpu and 2 to the chipset. So gone for a strix extreme one

Not sure how much RAM they were using in that article but I'm guessing 32GB - but 64GB is probably going to be slower booting than that.

Looked at your manual and there is no way that is possible unless you have your GPU in the bottom slot (slot3) rather than the top (slot 1) or you have some BIOS switch wrong like bifurcation, unless GPU Z is out of date or 4090 broken.

The more memory the longer the boot time, but it should not be switch the PC on, make a fresh coffee and come back to it long.

As for NVMe without bifurcation. The only motherboard I found was the Asrock Nova X870E.
 
What amuses me a bit in this context - my Lenovo Legion Go with AMD processor + DDR5 albeit LPDDR5X boots from button press to fully loaded desktop in sub 5 seconds - last BIOS time in the range 3.7-4.9 seconds.
 
for context my am5 system with 96gb of ram takes around 18-19 seconds to boot call it 20 or 21 just to be safe [i have stop watched it but in a very un exact science way so hence me giving an extra second or two to be safe]
thats on a sapphire b850 board 7800x3d and 2x48gb corsair 6000 cl30
first boot [around about 2 weeks ago give or take an hour ive had this pc running 2 weeks today] the first boot took 3 or 4 minutes at most because of hte memory training and after i enabled expo i think i had to let it do the same memory training on next boot but since then that 20 21 seconds or less has been hte rule must have booted her up 30 times or more since then
not sure how much this is helpfull probably not but thought it was worth mentioning
 
That seems quick, with this discussion I thought I would look at mine, its speed has never bothered me but it takes about 10s to get to the BIOS splash screen and 40 to desktop :o it does have a lot of things plugged into it though a 3 GPUs, 6x NVMes, a few SATA, a couple of 10G NICs, capture cards erc and loads all the WSL stuff.

I don't run fast boot as the Thunderbolt GPUs don't always register.

With fast boot enabled ~25s.
 
thats to log on screen then add another 10 or so to get to desktop
so your only like 10 seconds behind mine and im sure mine will start to take a little longer with time
ive also only atm got a pair of nvme drives and a single gpu connected really other than screens mouse keyboard and an audio interface
so in reality mines not that far different to yours really probably about 5-10 seconds in it if that and by the sounds fast boot enabled yours sounds like it might be actually slightly quicker than mine lol
il have a poke about in bios see if mine has any faster boot settings just out of interest
i dont need to make it faster or anything just look to see what options are there then use the internet to find out what those actually do purely out of interest

I don't know if I'm misunderstanding you, but that's not correct?

A lot of AMD boards will do 3x M.2 and a full 16 lane for graphics, even lower-end B650/B850 ones.

The board you currently own (like many X670E boards) can support up to 4x M.2 slots.

If your graphics card is running at only 4 lane, the problem is something else and it should be fixable:

Also, to be clear, you can't spend your way out of the lane/bandwidth restrictions. It doesn't matter if the board is £1000 or £150, they're subject to the same CPU/chipset limitations, though it is true that they can configure it differently.

X870/X870E motherboards in particular, are more likely to have issues with their M.2 slots than older X670/X670E boards, due to the presence of USB4.
