Hi all, please refer to my screenshots of my notes made regarding the backstory and things I have done to try and resolve it. Thankyou

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

As for your memory, you should stop with mixing and matching ram. Try with your old kit and populate slots A2 and B2.

Cpu — Intel i7-9700k
Cooler - AIO water cooler not sure of brand but it has normal temperatures during idle and when running
Motherboard - Z390 A Pro MSI
Ram - 4 x 2400mhz Hyper X Fury DDR4 (2 older 2 new about 1 year apart from purchasing the exact same kit)
Harddrive - WD Blue 1TB
GPU - Geforce 3060ti
PSU - Integrator Mod XT 750W 80 Plus Bronze ( Around 3 years old but only has 2 years of use )
Chasis - unrelated
Bios Version - MSI 7B98v1E ( Most up to date also installed yesterday )
Monitor - unrelated

As for using ram in the optimal slots, I stated that my ram does not work in any other slots than 1 with only my older sticks not the newer ones. Please refer to the test I conducted in the screenshots regarding what ram combinations do and don’t work. Thankyou for helping so far

This is where you made a mistake. The kit you bought first is compatible with your motherboard. So is the second one, they are the same. However the kit is TWO sticks. It is compatible and works properly only when you use a single kit of two sticks.
You are using 2 kits, 4 sticks of RAM in total. That is why you have problems. Those 4 sticks of RAM were never meant to be installed together. Only sticks that come in a kit are guaranteed to work. That's why they are sold in kits. Why do you think they don't sell them as single sticks? You could buy as many as you needed. But that cannot work. RAM is sensitive and must be tested before it is sold. When you buy a "kit", you buy RAM that has been tested.

How to solve it:
- use only one kit (your older kit)
- sell both the old and new kit, and replace with a single 4x kit (four sticks in one kit), or with a 2x kit that is twice the RAM size.

Oh for real? That does make sense actually but surely buying 2 sets of 2 sticks of ram that are the same wouldn’t be completely incompatible. I know it’s very common for people to start out with only 2 sticks and when they needed to upgrade just purchased another 2 sticks instead of an entire new set of 4. I will look into selling my set but this still doesn’t solve the issue with my 2 new sticks not working individually or in pairs in any of the slots without the older set so must that mean they are defected?

It's a 2 stick kit. The motherboard is compatible with it as a 2 stick kit. You put two of them and that's 4 sticks. The memory controller is all up in your area about that.

I know it’s very common for people to start out with only 2 sticks and when they needed to upgrade just purchased another 2 sticks instead of an entire new set of 4.

I know, and many of them get nervous breakdowns when the computer acts up.
Check out the threads on the forum and you'll see.

They might be. You said you bought an identical kit so they should both work when installed as a single 2 stick kit.

- Open command prompt (hit winkey, search for "cmd").
- Type in or paste this: "wmic memorychip get devicelocator, partnumber"
What are the partnumbers for your sticks? If you get two different numbers they are not the same kit. If they are identical, and the second kit doesn't work, then it's maybe defective.
