SwissArmyDruid posted:ASRock signal has been burning for months now, I want that drat MXM motherboard.  I said it in one of the threads but yeah, Epyc and Threadripper would both make killer GPGPU platforms too. Tons of lanes for good PCIe bandwidth (miners don't need this but actual compute programs do). Literally all you need is a CEB motherboard that takes MXM or mezzanine cards and you could build a water-cooled 1U rack server with quad (x16x16x16x8) cards that would keep up with the Tesla rack servers. With flexible risers you could get at least 4 air-cooled cards in a 2U chassis. You just loving know SuperMicro or someone is going to do it (I actually really like SuperMicro's stuff as much as Asrock/Asrock Rack, they both make some cool niche stuff and their quality is pretty solid from what I've read).

Which initializes down to, because things weren't confusing enough, "XBOX". Either that, or autocorrect, because my phone just tried to do the same thing when I typed "X Box One X" just now.

Combat Pretzel posted:L2ARC is nice, if you enable caching streaming data. I've added an 128GB L2ARC to my NAS and it's warm to the point I'm playing GTA and PU Battlegrounds straight from it instead of the spinning rust (I'm running Steam on an iSCSI share, over 10GbE). Streaming is on by default right? ZFS has some algorithm that prefetches stuff when needed, do you need to turn this on?

Yea, but it only fetches into primary ARC. L2ARC doesn't retain streaming data by default. Seems to be some algorithm that caches blocks that look popular, so that start of IO gets served out of L2ARC to give the disks time to start streaming. The relevant tunable is vfs.zfs.l2arc_noprefetch, set to 0. --edit: Wrong thread for this, anyway.

And this is why I just bought a 7700k instead of a 8 core Ryzen. I'm not going to deal with crashing on an expensive platform.

I am forced to conclude my first 7700k has better thermal goop and/or a smaller gap between the die and the heatspreader. I am actually considering deliding this recent cpu. Goddamnit Intel!

Ryzen systems seem 95% stable, some people found a way to make 5% of system unstable, and a lot seems to be issues with the BIOS/UEFI. Also the cost of supporting both platforms is roughly the same, so

"Using memory on the QVL and running the processor at stock clocks" shouldn't be capable of making a system unstable. Also, when using fast memory provides huge performance uplifts, it's hardly unexpected that people are going to use fast memory.

I still think the problem is an ever so slightly (like, 10mV) too low stock voltage for the stock clocks for the chips that would usually be considered a loss in the silicon lottery.

Paul MaudDib posted:"Using memory on the QVL and running the processor at stock clocks" shouldn't be capable of making a system unstable. Unless there is a legit problem with the memory itself, or the board? I really really have no heard of Ryzen system instability except in this interesting case (not specifically Wirths, rather the segfault issue on linux). Keep in mind you'll always get a disproportionate ratio of negative to positive feedback on anything, so yes I think this is an edge case until proven otherwise. 2933Mhz provides like a 10% improvement but it quickly hits diminishing returns according to those who reach 3200Mhz. IIRC, Ryzen has a Rambus PHY meant for 3200Mhz standard operation, it's possible faster memory isn't so much an uplift but rather that Ryzen is more or less shackled to an immature platfrom.

If you've got two identical CPUs and one of them gets 40 degrees hotter than the other, you need to do a better job with the heatsink and thermal paste.

The guys who leaked the first Ryzen benchmarks in december claim say there's a B2 stepping (focusing on SoC/PCIe controller errata) on the way. https://twitter.com/CPCHardware/status/876193860946468865 It's just a single tweet so  but perhaps that'll fix the virtualisation issues that they refuse to acknowledge.

FuturePastNow posted:If you've got two identical CPUs and one of them gets 40 degrees hotter than the other, you need to do a better job with the heatsink and thermal paste. Both have the same thermal compound and I checked and re-checked the connection to the heatspreader. If there is a problem I really can't tell where it is. I'll probably sell the Intel system off when Ryzen has a new stepping/fix.

Hope that B2 stepping lands in the Threadripper. Is two months to release enough time to get dies manufactured and packaged into the MCM?

The dies going into Threadripper *now* probably were made back in April/May. If B2 stepping of Zen is happening sometime soon, we probably won't be seeing it until the end of the year _at the earliest_.

Meh. Regardless of that, ECC memory, the fastest I've found is from Crucial, being DDR4-2666. However CAS is 19, not a fan of that. I wonder if the memory chips are binned well enough to be able to drive it down a lot, say to 15-16.

I fully expect TR/Epyc processors to launch with B2 steeping cores if such a thing already exists.

Consider the following: Threadripper mATX boards with triple PCIe 3.0x16 slots, into which you can attach NVMe SSDs on those quad sled things. Then you do soft-RAID with maybe like a 3-wide RAID10 or something. Or just one single 24 TB dataset. While I'm wishing for a pony how about also having the same 8 SATA + 1 NVMe M.2 of the Asus P10S-M WS, so that you can attach 8 commodity HDDs for secondary storage and a final NVMe M.2 drive with a buttload of L2ARC cache. Or you could connect an InfiniBand card in one of the PCIe slots and get remote DMA going and poo poo. No, let's go with having that engineered into the board too.  Asrack you better not disappoint, I have faith in your crazy design shenanigans!

What I'm getting from Threadripper is it's basically a deluxe version of Ryzen with twice the cores then an 1800X. Personally I'd love to buy and make my first AMD rig, but I'm concerned if the Threadripper boards and CPU will be way more costly than a Ryzen 7 rig, I just hope it's roughly the same price you'd get for an 1800X and they discount the 1800X itself, as well as cut the prices a little on the 1700 and 1600, etc.

Any word out if Ryzen rev.2 is going to use the same platform as the first-gen Ryzen? I intend to buy R7 1800X this fall, and once rev. 2 becomes available, swap the old R7 for a new 7nm part. I'd hate having to change mainboards just because of this.

We only know of Pinnacle Ridge and Zen 2, Pinnacle is 2018 and is basically Zen on a newer (better?) 14nm process, Zen 2 is slated for 2019 and is early 7nm.

3000MHz was all my budget would get, but even on an April BIOS for the Asus B350 Prime mobo I got, it worked just fine. Updating the BIOS, I'm able to hit 3200MHz @ 16-17-17-35 which I think is pretty good? I don't know much about RAM timings. Corsair vengeance LPX 2*8 3000MHz rated. R7 1700, but I don't think that matters at all. I think memory is mostly solved these days? E: it's not an AGESA 1.0.0.6 BIOS (or whatever the number is), either NewFatMike fucked around with this message at 15:01 on Jun 20, 2017 |
