MP 1,1-5,1 2010 Mac Pro 5,1 Ram decision - Help

[MadMax65]

I have a 2010 Mac Pro 5,1 with dual x5690's (12-core) & Radeon pulse sapphire 8gb running OCLP Sequoia and I have just gotten some ram for free so want to install those. I will never need to use this much RAM but since I've updated my system I might as well max everything out...... Specs will look great to me at least.
I have 8 sticks of each of the following:

Crucial
CT204872BB160B.36FED
16G8 240- PIN 2GX72 DOR3 PC3- 12

Samsung
M393B4G70BMO-YH9
32GB 4Rx4 PC3L-10600R 09-11-AB1-P2

I really don't want to keep shutting down and trying each sticks 2 by 2 and run into issues and I believe the higher ram needs some work done with OCLP first.

Questions:
1. Regardless of capacity, is one of the ram better than the other to use?
2. Will my system be able to use 6 or 8 sticks of the 16gb ram as is without having to do anything in OCLP?
3. Will my system be able to use 6 or 8 sticks of the 32gb ram as is without having to do anything in OCLP?
4. Are there instructions anywhere on what I will need to do with OCLP to maximize
my ram capacity.

I really don't want to keep shutting down and trying each sticks 2 by 2 and run into issues and I believe the higher ram needs some work done with OCLP first.

Questions:
1. Regardless of capacity, is one of the ram better than the other to use?

Only 2Rx4 will run at 1333MHz. 4Rx4 will run at 1066 or even 800MHz.

2. Will my system be able to use 6 or 8 sticks of the 16gb ram as is without having to do anything in OCLP?

Yes, but is not OCLP, OpenCore is what you need for manual RAM configuration.

3. Will my system be able to use 6 or 8 sticks of the 32gb ram as is without having to do anything in OCLP?

No. Only with manual DIMM configuration via manual OC config you can boot with 32GB DIMMs installed.

4. Are there instructions anywhere on what I will need to do with OCLP to maximize
my ram capacity.

This is the 32GB DIMM reference thread, everything you'll need is there:
