    Level 1 Techs on YouTube (Wendel) did a few videos regarding GPU pass through support on ryzen and how to get it working.

    It definitely isn't a CPU bug. I am kind of surprised that no one is currently doing any patches to fix this problem, especially since Threadripper is now a thing. At least there is an alternative, like Xen, if you want to do GPU passthrough.

    The PCI bug, however, is something that I hope gets fixed asap.

    Just so that you're aware before hand, Threadripper has a +27°C temp offset (similar to the +20°C offset on the 1700X/1800X) on what the temp sensors report vs the actual temps for fan curve reasons. A ton of reviewers missed this and ended up reporting inaccurate temps that inc. that offset and therefore were much higher than in reality. With a decent 240mm+ Asetek AIO with thermal paste covering the entire water-block (not just the center like with the pre-applied paste) you should be seeing actual load temps no higher than the mid-high 60°'s with stock settings. And the mid-high 70°'s with a moderate OC. Toasty, sure, but not unreasonable at all considering the sheer amounts of CPU power being pushed.

    Yes, they are. Have a look at support pages of the vendors.
    Do you have any links?
    I can only find e.g. "Supports ECC UDIMM memory", which is true for every mainboard, as every mainboard supports ECC memory, but only in non-ECC mode :-(

    Why in the hell are you benchmarking against dual Intel Xeon Gold 6138 Tyan Server?

    40 Cores/80 Threads vs 16/32 and the best part, when EPYC arrives for Server v. Server you better test against the Tyan or people will find your `objectivity' skewed.

    The EPYC will win out and anyone still buying Intel hardware will look like fools.

    Gamer benchmarks on server chips have just as much value as NAS benchmarks on desktop chips.

    You don't focus on the method, you focus on what drives the result. If Crysis makes a large use of some function that requires the CPU supply "X", then the bench has merit.

    Likewise when running specialized function tests (ie: NAS) on a desktop CPU, it can expose how well a particular function behaves.

    Also, one can validate across benchmarks on certain behaviors the CPU provides. Why does one bench show well on this CPU and bad on another when they seem the same?

    Gamer benchmarks have exposed more issues in datacenter oriented hardware than I ever imagined.

    Michael, do you plan to look into the KVM NPT that affects all AMD CPUs?

    Also, are you going to look into the PCI bug that affects GPUs on threadripper.
