Swear to god I haven't heard "ECC" since the rambus days and am completely mystified as to why everyone thinks this is super important all of a sudden this month.

Because some people want to use higher core/thread count CPUs for stuff where ECC makes sense (IE not gaming). Large file servers, virtual machine workstations, etc. I think a few people got excited that we might be getting an ECC platform that isn't associated to Server CPUs.

If you're only plunking around with a couple of TB worth of data, ECC memory isn't going to make much of a difference.

When you start getting into arrays that are 32TB+ in size and moving around a LOT of data each and every day, ECC memory becomes something very nice to have.

code:


pool: linux_isos_01
 state: ONLINE
  scan: scrub in progress since Fri May  5 10:26:55 2017
        5.51T scanned out of 17.9T at 285M/s, 12h37m to go
        0 repaired, 30.82% done

That's just one of 3 32TB ZFS pool being scrubbed :shobon:

I don't run ECC here, but I probably should.

I think the 2GB / 1 TB comes from people talking about enabling DEDUP on large arrays. You can just as easily offload that to a SSD cache

Maybe I can swing one of the tiny Ryzens for my Plex Transcoder server since for whatever the hell reason Plex refuses to just send raw audio for any of my newest content anymore and the NAS just can't handle it.

It's usually DTS audio that causes a huge problem with this. Re-rip and transcode the audio to AC3 for a much better experience. Plex is really finicky as to which devices it'll direct stream DTS to. Heck even AC3 can be a PITA as well.

I thought the majority of games running 4k on consoles were all running some kind of rendering trucks like checker board. To get the visual quality they do at 1080p in 4k, I doubt any consoles could do legitimate native 4k. The 1070 barely does 30 fps in Ghost Recon Wildlands and less then 30 in Deus Ex, surprisingly gets ~50 fps in BF1.

A lot of games also do a TON of dynamic resolution scaling at various parts of the render path. DOOM is a great example of this.

Is there a software patch with ~5% average performance impact on Ryzen that I don't know about?

Errata happen, available mitigations matter. And we don't even have a documented scope of the exploit here - not even a kernel-team consensus about whether it affects AMD or not. It's serious, but the exact trigger conditions are still embargo'd.

As I said in the Intel thread, though, there are definitely cases like databases that Intel had previously smoked Epyc in that are going to poo poo the bed (or at least be competitive) on existing silicon with this patch. There is going to be a pretty serious incentive for players on existing silicon to turtle up their databases and SANs as separate dedicated appliances that you know will only be executing trusted code from you and no others (and can thus run nopti and ignore the performance impact). It's a huge blow to the whole hyperconverged concept - and/or AMD gains a big advantage in this area.

This is on existing code, too, though, and vendors may be able to drop that performance impact a little bit by optimizing for syscalls even harder now that they have become slower.

I think he was calling you out more on your choice of words than anything else. You were quite severe with your language about the AMD segfault issue and seem to be sweeping things under the rug, so to say, about Intel's very big, huge, massive problem affecting basically all their CPUs. In general you do come across as being a bit more Intel fanboyish than I think you realize :shobon:

So yeah, to be frank this one's a nothingburger as far as end users are concerned. That's not spin, that's a realistic assessment of the situation.

Performance is one thing, security is the other really big problem here. Sure it'll be patched out, it still doesn't change the hand waving you've done

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?

Methylethylaldehyde posted:

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.

So I have an ASROCK x370 board and the Gigabyte x399 board and have to say that both have been REALLY rock solid. Previous built as an i5-2500k/i7-3770k on a gigabyte board that ran super OC'd for years without a glitch.

Gigabyte x399 board is running my Threadripper @ 4.1 GHz with just 1.3vcore so I'm pretty impressed with that.

From a feature perspective I think the ASROCK board has a better UEFI Bios, but the Gigabyte board has better Audio + Network stack for gaming (SB Studio vs 720) (5GbE vs KILLER NIC).

Do you actually use the KILLER NIC? I found it to be an endless source of issues, disabled it and only use the Intel port now.

I've not had any problems with it. I didn't bother with the Killer Nic software though. It's probably garbage anyway.

It appears to not have every single slot on the board illuminated, though.

The RGB lights don't really bother me since I have it inside a case that uses sound dampening instead of glass and windows and such. I just checked the BIOS between the two and they look to be identical. So far it's been a rock solid board so I'd assume the Designaire would be pretty drat good too. My only gripe is they appear to be behind on BIOS updates.

Are people intentionally ignoring you can generally reflash the bios from the OS? Does that not apply here for some reason?

Still requires root + signed BIOS from the Vendor. It's not a question of CAN you, but how difficult would this be to exploit. If you already have root and signed drivers it's well past the, game over man, stage of things.

I just meant, dismissing it on "flashing bios" grounds seems kinda weird. Why not dismiss it on "this only effects state/corporate espionage" type arguments instead?

I don't think these exploits are significant.

No one is dismissing anything. They are indeed exploits. You could do the exact same thing to X platform if you have:

code:

A) Root Access
B) Signed drivers/code to bypass protection

If we compare to Spectre/Meltdown you didn't need any of those. You could simply run a java script and presto you're reading from memory that you should have 0 access to.

Gosh how did you guess all of those?! Yeah, at work they gave me a 24 inch 1080 secondary monitor to go with a high-DPI laptop. At home I have a high-DPI main monitor and an old 1200x1600 secondary.

The odd thing, to me, is it only happens with Visual Studio and derivatives. Like, what zany-assed thing are they doing that nobody else seems to be doing? Nothing else fuckes up like that, that I've found, at least.

Microsoft is horrible when it comes to their UI elements following their own design principles. Event viewer, Taskmanager and a bunch of other apps within Windows also end up looking like crap.

The latest build of Windows 10 fixes a lot of these (but if you plug/unplug monitors without logging out you still get odd results). If you're on Win 7/8 :rip:

I'd bought the same motherboard initially thinking I wasn't interested in much overclocking. My friend who works at a tech store laughs at me for now having a 280mm AIO on a board that can hardly overclock so odds are I'll be giving X470 a try sooner than later.

This is why I almost always go for a more top end board. You never know when you might want some of the extra features and it sucks having to replace a motherboard. Grabbed an x370 for my Ryzen 7 and well there was only one option (x399) for my 1950x. Couldn't be happier with the builds.
