Ah yes, PCS sent the new RAM sticks and since installation of them, have had 0 issues since then. I did share this issue around with a few friends here and there, and a few of them did mention if I also enabled XMP in BIOS to overclock the RAM. I told them I haven't, and they did advise me to enable it back then. Ofcourse, I listened to them and enabled it but had issues after 15-20 minutes where my computer would just freeze, and everything became unresponsive. Only holding the power button and rebooting would only solve this issue, until it happened again. In the end, I did just give up and disabled it and I haven't touched it since then. That was a good 10-11 months away though. Only today has it just clicked in my head that I can be asking for support on this matter, so here I am now.

So you previously removed the XMP? Did PCS do the RMA themselves or did they just ship you replacement RAM?

So what XMP are you applying?

What part numbers are the DIMMS?

You need to clearly outline what it is you’re doing for to be able to see where the issue may lie, at the moment you have given any detail of what it is you’re trying to do.

So very first thing, you've got an air cooler on a very hot CPU, you need to run a CPU stress test with Prime95 to determine where your throttling temps lie.

12th Gen CPU's were known to warp inside the socket due to unbalanced pressure applied which causes issues with cooling over the longer term.

You'll only be able to apply a memory overclock if there is enough thermal headroom on the CPU to do so.

Okay, so ive ran Prime95, and from what I can see is a results.txt file and it contains the following:

[Sun Nov 17 16:53:36 2024]
FATAL ERROR: Rounding was 0.4973681423, expected less than 0.4
Hardware failure detected running 384K FFT size, consult stress.txt file.
FATAL ERROR: Final result was 00000000, expected: 3D4F6CBB.
Hardware failure detected running 384K FFT size, consult stress.txt file.
FATAL ERROR: Final result was 00000000, expected: 3D4F6CBB.

So I meant the temp results. You need a temp program like HWMonitor open during the test with expanded CPU readings, reboot the pc, open HWMonitor and keep it open during the test, then run prime95 for 10 minutes and take a screenshot of HWMonitor after 10 minutes whilst prime95 is still running

Obviously this is without any XMP applied

Don't think you're following what's been requested, suggest re-reading it.

But anyway, with the data we have, you can see the package temperature is over 90c. At 90c the CPU starts to thermal throttle and reduce it's clock speeds. Intel stated their TJMax on that CPU was 100c, but they've simply lied through their teeth as they've clearly labelled the clocks that aren't available as "Thermal Velocity Boost"

So with that cooler, the CPU is thermal throttling. It would need to be kept under 90c when under 100% load to be considered not thermal throttling IMHO.

When did you buy the system?
Is there any overclock set on the CPU? I would double check this, as if there is any motherboard boost being applied, that could well be another factor. Often boards apply basic OC's out of the factory.

My solution would be to

1/. Buy an adequate cooler, either an H150i mounted to the front of the case, or an H115i mounted on the roof.

2/. Be certain no motherboard overclocks applied to the CPU, set default power limits.

3/. Take off any overclock on the GPU just for testing.

4/. Run stress tests with XMP1 applied

5/. If issue reoccurs, I would do an RMA, if it doesn't hooray.
