I had the chance to exchange CPU from PC1 with CPU from PC2.
PC1
Supermicro X13SAE with i7-13700Kstrong (this seems to be the one with the better/more robust integrated Memcontroller)
PC2
Asus WS W680 with i7-13700Kweak
When I install i7-13700Kweak into the Supermicro Board it is booting and everything is okay.
When I install i7-13700Kstrong into the Asus Board it is booting and everything is okay.
I didn't boot into Windows as i don't want to "loose the activation after hardware change".
But I was running Memtest.
So now I know more but I don't know what to do i7-13700Kweak
And next thing that bugs me:
I am a fan of dedicated TPM-Modules.
For the Supermicro board you needed to buy a dedicated TPM-Module because the Supermicro Board was deactivating the integrated TPM of the CPU.
In the last 2 years with Win11 I installed dedicated TPM-Modules into my PCs because I had less trouble.
But with the Asus Board and dedicated TPM I reached slower Memory speeds (DDR5-4200) than with integrated TPM (DDR5-4400)
I don't know the reason for this.
I had to deactivate TPM and secure boot to boot memtest(because memtest has no signed bootloader).
So I think that a memory stress test inside Win11 with activated Core Isolation / Memory Integrity / ECC could be more demanding to the integrated memory controller.
I miss a Raptor Lake Xeon SKU.
I would buy this SKU without a doubt.
I want a SKU with a harder quality control.
This is like going into a casino - completely frustrating.
Hmm, sorry to hear that, and that is very interesting and I can also imagine, frustrating in regards to the memory controller differences, plus what you are noticing with the dedicated TPM vs. Supermicro approach.
I am still pondering some of the bugs or kinks that the ASUS WS680 ACE might have and your specific experience, because of what I just went through in upgrading to the latest BIOS 2305 after performing the "ME" update with ASUS ME update tool.
I was stuck in a boot loop and kept having the video card driver black screen of death the entire system after this BIOS update and it make me think about some of your situation and settings.
I know that you did a lot of things to try and get things running, but I am still finding your IMC story intriguing.
I am in a situation, where given the WS680 ACE IPMI's pages and pages of BIOS settings, I realized that ASUS' "profile saving" feature just stinks and I lost all my tweaks, which might have resulted in my boot loop situation.
As a note - I got the system back up and running now, after turning off all ASUS enhancements and using Intel default CPU settings, so I wonder if there is something else in the BIOS code or settings that could also be a culprit in your situation. As a note, I had to fix/set my DDR5 memory settings to DDR5-4800 and leave everything else at AUTO, so I wonder if there is an issue in ASUS' memory code as they introduced features to "improve memory stability" I have a feeling another BIOS will come out sooner than later.
I'll have to give some thought about your whole experience with a "weak" IMC vs. a "strong" IMC, and I also agree, I would love a Raptor Lake Xeon SKU, there really is a quality control difference with Xeon's it would appear, even if they wouldn't permit overly exotic memory overclocking or core overclocking, I am sure some of the things you are seeing would be a non-issue in a Xeon based SKU.
Re: loosing Windows activation - if you call Microsoft and explain your situation, I wonder if they would permit you to swap CPUs, to enable you to essentially have a reset of hardware activations. I used to have the impression that they permitted at least 1 major change per key - but - I'll also admit that I've never seen it done before with a CPU swap, and it sounds like you have far more experience than I do.
Thanks for sharing your experiences and it does give me some pause about the whole IMC situation, it's not something I've ever thought to be a thing on Intel. I've experienced it first had on my first Ryzen 1700X, which had an absolutely horrible IMC, but I never imagined an Intel CPU ever having a weak IMC!
Cheers and take care!
