I’m going to be installing a new motherboard/CPU combo on my system. w.r.t. the OS will I:
The CPU is going from a quad I5 to a quad I7
Going from DDR3 to DDR5 RAM
Going from an ASUS to an ASRock motherboard.
I suspect the new install is cleaner/faster but would like to avoid re-installing a bunch of programs if possible. Thanks in advance.
No.
Probably not. Try booting the fallback image.
Is your GPU changing?
Intel makes a quad-core i7 that supports DDR5?
The Linux kernel has likely supported all of your old hardware, and will continue to support your new hardware. One common exception to this might be the official Nvidia drivers, but there’s the open source nouveau driver to fall back on there.
You might need to ensure your BIOS/UEFI settings are ready to play well though. Typically that just means:
Thanks for the responses. No, the GPU (Nvidia) is not changing.
The exact CPU is i7-12700KF (box says Intel CORE 12th gen). It is supposed to work with the motherboard so I am assuming it supports DDR5.
My current motherboard is UEFI so I know the config settings.
So for clarity, it’s not a “quad I7”, it’s a 12-core i7 (8 performance, 4 efficient) 
That is correct - I mistook “4 efficent cores” for “4 cores”.
Got everything assembled, and … problems.
Powers on, but DRAM error light goes on and stays on (CPU light starts on but goes off).
Powers off by holding switch down, but will not power back up without cycling the power supply switch.
I have tried combinations of the sticks in the the various slots with no change in result.
Is there a simple way to tell if it’s the motherboard, RAM sticks or something else? That there are two problems point towards the MB for me. Also, my old system used DDR3 so I can’t try using sticks from that MB for troubleshooting.
To refresh, the HW is:
i7-12700KF CPU
2 DDR5 32 GB RAM sticks.
ASRock Z790 Pro RS motherboard.
Thermaltake V100 case
Thanks in advance for any suggestions.
EDIT: Powerup was done with no disks, keyboard, or mouse.
The specs might be compatible on paper, but in case the motherboard won’t even post with these memory modules, those would be your major problem.
From the Intel site :
Memory Types
Up to DDR5 4800 MT/s
Not sure but maybe the I7 can’t handle the RAM one way or an other , might be worth to do some research on that I guess.
Maybe take a look at this site:https://eu.crucial.com/support/articles-faq-memory/problems-with-new-memory
That could definitely pose some diffugulties. Thanks.
RAM is passive. You can run faster RAM at lower speeds without issue. Most boards will do that by default.
Also, the stated supported memory speeds are almost always lower than the speeds most people run their memory at.
Your memory module could be incompatible with your system. There are a lot of considerations when choosing the correct memory for your system, including memory type, speeds, densities, and more. To take the guesswork out of this, use the Crucial System Scanner or Crucial Advisor tool to find a guaranteed compatible upgrade.
This was taken from the site of Crucial , from the link I posted earlier, one of the things mentioned is speed. So this is a bit confusing if you ask me.
Just want to make sure I understand: If the CPU spec says it can only support only 4800 DDR5, it should be able to run 6000 DDR5 at 4800? The memory speed is a nonissue at the motherboard level.
Thanks, I’ve looked up RAM that is compatible with the CPU. Also, the Teamgroup site says the RAM I have is compatible with the motherboard.
Yes, you can run it at a slower speed.
Check your settings in the BIOS and see what speed it is set to now.
Psi. I had done all the previous without a monitor or keyboard thinking it didn’t matter. Apparently it does these days. Once I did hook up the monitor, KB and mouse I got a prompt to configure the BIOS and once I set time and ‘auto’ XMP it was happy with the RAM.
