Another day, another Megaherz. :)

With almost every BIOS update I get to bump the RAM speed, which up until today I ran at 3200 but the latest update allows me to run it at 3333 MHz. Still not the full bottle yet, though I totally splurged out on this and went for 32 gigs of 3600 MHz sticks! :)

But does it actually run the os at that speed? :v:

Wouldn't take more than 10 or so tries to narrow it down if you just cut in half each time. That said, if you can get a TR 1950x to work in a workstation Epyc motherboard that has unborked IOMMU and ECC support, I could see them being pretty kickass for certain kinds of simulation work, the kind where the sim doesn't scale well past about 16-24 cores, so having tons of Ghz to throw at it would work nicely.

IOMMU and ECC work properly with TR. Pretty sure the IOMMU problem was a known issue with KVM.

I've been toying with the idea of doing a virtualized Win 10 overtop KVM or whatever the latest and greatest is these days. Anyone have a link or two to some guides? What's the best VM to run on Linux these days for GPU(Nvidia)/Audio passthrough?

Not really? Win 10 and Server 2012 won't boot if you have IOMMU enabled. I had to disable it to get it to do more than sit on the black loading screen. Perhaps they fixed it in recent BIOSes, I'll have to shut everything down and check again.

ECC works great, and makes overclocking RAM super easy, since you can run the test while watching the system log for the ECC errors to report themselves.

Blank screen is still probably a KVM issue as there are patches to the kernel + a userland program to re-connect the device if it disconnects the GPU, or a shutdown of the VM causes a problem with D0-D3 state transitions. I mean, it still could be a platform wide PCI-E problem. I remember the old NPT problem which turned out to be a KVM bug. Wouldn't be surprised if that's the case here as well.

If your issue is the D0-D3 state bug where lspci -v shows FF as the header for the guest GPU https://www.reddit.com/r/VFIO/comments/7slj72/threadripper_reset_patch/ has your fix.

a. reverse-mergers only work between a private company and a public one, so the private company would need to wealthy enough to buy AMD in a reverse merger, then subsequently buy Company X that you want to merge AMD with.

b. the license agreement specifically defines by ownership of the company such that any entity owning more than 50% of the company constitutes a Change of Control. AMD had to get clever just to make that work with just the GloFo spinoff (by splitting GloFo's voting rights and assets differently), you'd need to be way more clever to go the other direction.


the x86 license deal isn't impossible to evade, just fantastically expensive in legal bullshit.

Yep, it's only Spectre that Zen is vulnerable to, and only somewhat as the mitigation of such a vulnerability apparently costs next to nothing, and well Spectre is harder to exploit to begin with.

Also, earnings report dropped http://ir.amd.com/news-releases/news-release-details/amd-reports-fourth-quarter-and-annual-2017-financial-results

They beat their expectations, second quarter of GAAP profitability in years, and it's the weakest quarter as well. Looking to see AMD break 100-150m in profitability soon.

The silicon only has one CCX, so 4 cores in the max. An 8 core + 11 Vega CUs APU would likely be a big chunk of silicon that would require a high price and high TDP, and then you run into the small market problem. How many people are willing to spend $400+ on an 8 core APU with mediocre built in graphics and lower clocks than the $300 variant without the GPU?

I didn't know that other part. The 4 core part is priced aggressively and seems nice, but the problem is it has 4 cores. I'm building a workstation to run the linux on and I'll just use my old gtx 670 I guess.

with a 10-40W TDP, most of these things are going to end up in ultrabooks, where 4 cores is a huge upgrade over what you're currently getting (two :v:)

Just use Linux and install Windows as a VM on KVM. Since server 2008R2, Windows server has become a shitshow in my opinion. ( 2012R2 is okay, but whoever thought it would be a good idea to have the 8.1 desktop on a server where you need to mouse in the left bottom corner in an RDP session to access options needs to be fired. )

Does he say which firmware he's running on/which ones hes tried? IIRC ASUS has pushed multiple beta and maybe even a release firmware update out with hilariously unsafe defaults (like 1.8v SOC!!!) They? or maybe another company also recently pushed out older fw with a new name.

Every time you update fw it's important to double check voltages, they aren't the only company to have made the 1.8v soc mistake. Never saw anything official about this but it was supposedly the result of some sort of reference versioning mismatch from AMD


Also, my 2x16 CL153000 Corsair LPX (SK Hynix) happily runs at 16/22/22/22/53 3200 with the latest fw on this AX370 Gaming 5. I was going way out of my way trying to lock something down with that ryzen timing calculator, turns out you can just turn XMP off, set the frequency to 3200, leave all of the timings to auto, and only adjust ProcODT/SOC/DRAM voltages (80/1.125/1.4)

I have 4x8 CL163200 Corsair in my Monero box that I will swap out and try later, some people have gotten two of these to 3600.

Was skeptical of the benefit, but jumping from 2933 to 3200 was good for 550 points on Firestrike Combined. Max framerates haven't changed all that much, but worst case minimums are ~7.5% higher. I feel like I said the exact same thing when I jumped from 2666 to 2933. I'm lowkey impressed they managed to get ram compatibility to this point only a year in

I had originally chosen the Gaming 5 because it's like, one of 3 boards with a clock generator, but Gigabyte still hasn't given us access to it via firmware :sigh:

1920x has identical hashing performance to 1950x at 3/4 the price because the consumer chips only have 32MB L3 cache. If epyc were cheaper, the 16 core 64MB L3 cache variant would have double the hash rate of either. If the 1900x had 32MB L3 cache it too would have identical performance to the 1950x for mining, but it doesn't.

I don't write shill tech review articles or like the pointless mining of crypto, but I'm sure someone here will try to justify buying an x399 system over an r7 based on this bridging the gap. You need to make ($600+$330-$270-$90) $630 dollars mining to bridge the gap. Not doing the math on that, but assuming stable anything from crypto is a bad bet and it'd take somewhere between 6 and 12 months at current rates. With these articles being printed, it's going to never pay off.
