A quick update for anyone who finds this thread in the future.

I heard back from tech support along with getting in touch with the developer of HWinfo. HWinfo v7.40 now displays the correct clock speed of the memory. CPUz was showing correct clock speeds, but they jump around depending on load - thats why screenshot in review showed 1333. I also had a problem along the way with a Timetec 2x16gb 3200 dual rank 2Rx8 kit which ended up being incorrectly labelled as they were 3200 by XMP only and 2666 JEDEC. I now have re-ordered the same kit and received 3200 JEDEC which works as intended.

For those interested, the thunderbolt ports work well with a Gigabyte 2080ti eGPU. This also takes a lot of load from the CPU and keeps temps to a more reasonable level. I was getting very tempted to try liquid metal on the CPU to help heat get out of the chip. Some Asus ROG laptops like the Flow X13 come with liquid metal from factory which may well be my next laptop.

I otherwise found reasonable reduction of the temp spikes by running windows 10/11 performance setting to "best efficiency" which caps the turbo limit and performance is still reasonable.

Hope this info helps someone!
Cheers

One thing I noticed though - the RAM is supposed to be DDR4-3200, yet in the CPU-z and HWInfo screenshots, the RAM speed is 1333 (x2 = 2666MT/s) not 3200... I'm wondering if it was a BIOS limitation that needs an update, or perhaps a change of RAM sticks.

I have since purchased this laptop and did some testing.

The 1x16gb 3200 c22 module it came with only shows up to 1333 mhz (2666 equiv). Yet strangely it occasionally shows the CAS latency at c22 (the speed for 1600mhz by jedec spec), almost like it's trying to reach 1600 mhz but has some limitation - either BIOS or hardware. The intel page for the i5-1240p lists ram speed as 3200 (1600mhz)... so why is it stuck at 1333? I'll try and reach out to support.

Also, I have purchased and tried 2x16gb 3200 c22 sticks, and they also run at 1333mhz (2666) c19, so its not the original sticks at fault.

Thank you for the review, much appreciated!
One info: perhaps do you happen to know the model/part number of the specific unit that was tested?

E.g.: PMM2AU-00T005, PMM2AE-0KH01HDU, X40-K-10Z, X40-K1437 etc.

Thank you!
