Can unsupported ram not boot PC?

[Azad_Singh]

If ram isn't on the support list of the motherboard manufactures compatibility list then will the PC still boot or it wont?

It can prevent it from booting.

What is your motherboard and Ram?
If your ram and motherboard have different generations (DDR, DDR2, DDR3 or DDR4) then you won't be able to work with it at all. But if the clock speeds are different then the motherboard will just underclock the RAM and it should boot.

Hi,
The QVL list is not comprehensive, so there are plenty of modules that will work that are not listed.

In general, I recommend Corsair or G.Skill, and then Google your specific motherboard model to find know models that work well.

RYZEN in particular has had some growing pains with DDR4 compatibility. You should definitely update the BIOS for most motherboards as that can fix issues which includes periodic PROFILES added for memory (so it can recognize the stick to apply the OPTIMAL profile).

So to summarize:
1) Look for stick on QVL or known to work via word-of-mouth

2) ensure bandwidth is sufficient (i.e. 2x8GB 3200MHz DDR4 for Ryzen and some Intel CPU's) to avoid bottlenecking the CPU

3) see motherboard MANUAL for memory placement

4) set to "XMP" (Intel) or appropriate setting for quick, optimal default in BIOS (Ryzen can be problematic still and may need some tweaking)

5) run MEMTEST86 to test memory (run full pass or until errors) www.memtest86.com

6) avoid CPU overclocking if an option at first to ensure system seems reliable (and restest memory if you overclock)

Hi my friend.
I couldn't agree more.
