ASUS KRPA-U16 not working with EPYC 7D13 (100-000000322)

[RageBone]

Even more mysterious than the 7D12/7D13 is the motherboard, which I've hardly ever seen with only four channels of RAM except for ITX.
The 7D12 seems to be a purpose-built CPU for storage. Some boards may not light up the machine if the memory is plugged in full. Only the four outermost channels (CDGH) are available.

Hahaha, the other day at OCP Facebook announced the project called North Dome, which is supposed to be the source of 7D12/7D13.

North Dome is 6 channel as far as i have seen and Docs claim it to be completely compatible with basically all epyc CPUs.
Milan preferred and only validated with 95W SKUs.
I found nothing obvious why those 7D13 CPUs are supposed to just work on North Dome.
Of course that changes should we get a North Dome Biosfile

Did you happen to run any CPU benchmarks on this 7D12 CPU? Many other system components added up the power usage, what was the actual idle and loaded power consumption?

I did, but never published them. I'll give it another try sometime

If you could would be great. I haven't seen anyone publish the CPU benchmark for this EPYC sku on benchmark.net or openbenchmarking.org or other place except this one on youtube in Japanese language:

i noticed in this video they attempted to raise the power limit to 105W, but only changed one of the necessary fields. you need to change both the cTDP and the Package Power Limit fields. maybe it can go up higher if they change both.

Precision Boost Overdrive on Epycs lmao

wut? i didnt mention PBO.

some EPYCs do support configurable TDP (cTDP). the 7402P for example ships with a default TDP of 180W, but this is configurable between 165-200W. bumping the cTDP up to 200W will increase clocks under heavy situations where the power limit pulls the clocks below the max of 3.35GHz. while at 200W cTDP they remain pegged at 3.35GHz.

or my 7642's which have a default of 225W, and I can squeeze another 2-300MHz out of it by bumping it to 240W

if you can raise the cTDP on this 7D12 chip, it will most certainly raise the core clocks.

I suppose the joke didn't come over properly. Oh well.

Ooh nice find. Has this person shared how they got it working? Still have one lying around

i hope this information is coming soon too.
