Illegal, unsupported, legal.  Doesn't matter.  The point is that there's expected behaviours and if a CPU crashes or is able to be elevated to a privelage level it shouldn't be at then it's a big security hole, and especially for enterprise markets puts a big ding in your reputation.

Ryzen 3 and 5 are like the ryzen 7 with a ccx between sets of cores

Ryzen 3: 2:2
Ryzen 5: 3:3
Ryzen 7: 4:4

Hence only 4, 6 and 8 cores CPUs for ryzen

That's true but not true at the same time. It is true that having a CPU doing something unexpected is not something your company wants to deal with. However, it is not true that ALL enterprise markets will be running the same configuration. Most if not all enterprise will be utilising custom-made software that is tailored to some degree to their work.

 

Anyway, I'll digress and get back to what's happened with the Ryzen. ATM, I've managed to boot the Hynix RAM sticks to 2400MHz but any further = board hang so it does seem like the AGESA isn't liking my RAM. BIOS updates is rather pathetic but given how Asus is prioritising the C6H, this does mean that the Prime does get some loving soon. Managed to O/C to 3.7GHz at 1.20v which is rather surprising and I probably can push further to 3.9GHz. Cooling might be a problem but it seems the stock cooler is still hanging in there. I did a burn test with XCOM2 which heats my system hard and the temps were hovering at 62C max. Not bad...

I'm hearing Ryzen isn't compatible with a lot of RAM. Hope it's just buggy board BIOSes.

Most of the RAM can boot at standard JEDEC 2133MHz speed and timings. But it is the higher speed that is the problem since the InfinityFabric is dependent on RAM speed. Once the AGESA is settled, then we should start to see a lot more speed into these things.

I guess if you have 2 weeks to write a uefi/bios this is to be expected.

It's not like they're done from scratch.  The overall framework is much the same, just specifics like register locations that change.

But really, like any new architecture the edgy stuff is where the learning curve is.  Look back at most high profile overclocking motherboards, it took some of them multiple months and several Bios revisions before they got near their peak capability.

Someone said the original launch was like 1 month further ahead ...
