AMD Ryzen 3000 Builders Thread

[GhostPirateLeChuck]

IEC answered your username question.

As for the memory. I would recommend 4 x 16 gig at least 3200. Faster than that or better timings may or may not affect the 3900x. I have a build on the way, so I can only say by the reviews, it only marginally affects performance.

So the difference between CL14, CL15, and CL16 all at 3200 isn't that dramatic? If not, that'll let me shave off a few bucks on the build.

(I've got everything except the CPU, motherboard, and RAM on the way)

Has anyone found any xfr frequency chart yet comparing x370, x470 and x570 for the 3rd gen CPU's yet?

I wouldn't bet the farm either way, its just that the reviews seems to think its only 1-2% or so. Like I said, personally I am going 3733 cl15, but do whatever your budget says.

I'm building on an X470 board with the 3900X, so we should have at least 1 more data point on effective boost clocks with older boards soon™

That actually sounds pretty good. I'd even be fine with slightly larger perf penalty, since the vast majority of the time, it'll be running VMs in Cisco VIRL, or multivendor VMs (like Juniper, Arista, etc...) in GNS3, with a bunch of Windows apps and boatload of tabs open in Chrome, and terminals for my network hardware, while I'm answering students, with light gaming and Youtube videos on the side after hours.

I was more worried about a penalty akin to what I'd seen posted about using 4 DIMMs with the previous 2x00 generation, where populating all four slots would result in 3200 DDR4 suddenly plummeting to 1833 (or something thereabouts). ASUS does list some 4x16GB kits on the QVL for the x570 Strix-E (3600 CL16, though), so I should be OK on that front. The 3200 section of that QVL is sparse beyond belief, though.

The 1000 series also had all sorts of bios problems. I can;t wait to see how my 3900x does on a x470 motherboard.

I'm a dummy, but I get the feeling that going with/sticking to your 470 or 450 Mobos this time around, in the early light of this release is maybe better than the first run x5xx boards? Correct me if I'm wrong, but VIA is *supposed* to be providing these chipsets but was design/supply constrained, so those chipsets are basically harvested 14nm AMD chips, right? Not what was planned and, possibly, quite part of the issue with crazy thermals and less-than-expected power draw in some applications.

I compare to the Zen 1 release, where things were so messy for so long with the only boards that were barely available, and it seems that these chips, in relative abundance, work really quite well with the previous gen AM4 if, at the absolute worst, a stopgap until the ftrue beast "rev2" 5xx boards are released without, say, the chipset fan and other more favorable power features? I dunno.

I have the feeling that a lot of the solid x470 boards will be solid options for Zen2, for at least a couple of years, because it sounds like they also aren't limited by memory speed (seems entirely based on the CPU's CCX, no?). sounds like all you really miss out on is some extra PCI lanes (important for some people, of course), and maximum ultra Hulk-Hogan-Eat-your-heart-out-(for some reason)-back flip-on-a-BMX-bike PCIe4 speeds?

(ugh, it's from the movie RAD...can't find this scene anywhere on Youtube. It's amazing stupid 80s stuff, but I think Hogan's lawyers have nixed it because of his ~recent legal issues, lol. Watch Rad. It's tubular and you'll hate me forever for wasting that 1 and a half hours of your life)

I would not worry as much this generation about QVL. Get 4 x 16 gig as fast as the budget allows and you will be fine IMO.

If I am wrong, sorry, but after all the reviews, this is what I am seeing.

3800X is finally in stock as of now @Amazon.

AMD has spent huge CPU resources, most prominently the so-called "GameCache," to mask latency. With the new 3000 series, I do not think we will see memory-related performance scaling as we did in the past.

From the TPU test. Even 2666 16 looks good.

Oooo! NICE! That definitely helps. Thanks!

Now it's just a matter of NewEgg getting 3900Xs in stock long enough for me to actually be able to order one...

 

[ClockHound]

Or just get two 3600x and some duct tape for homemade chip-stacking VM drama....;-)

 

[B-Riz]

I'm in the middle of ordering parts for a 3900X build for work (I run lots of VMs in WS Pro, and multitask with apps running in Windows at the same time), and want to add 64GB RAM to it. I've got 32GB DDR3 in the current desktop I've got now (it still has a i7 2600K CPU), and some of these VMs need a minimum of 16GB RAM and 4 core *per instance*, so 64GB would at least give me some breathing room.

I guess my first question (of many), is how much difference would I see using 4x16GB 3200 CL16 DIMMs vs 3200 CL14 (or CL15) DIMMs? Corsair has a 64GB LPX kit with 16-18-18-36 timings for $300, while G.Skill has 64GB 3200 kits ranging from 16-18-18-38 for $328, 15-15-15-35 for $465, and 14-14-14-34 for $530. I'm only going to be gaming on the side, and even those aren't super demanding (more old school fighting games, shmups, etc...)

I'd love to try a pair of those 32GB DIMMs with 14-15-15-35 timings, but considering that NewEgg has a grand total of two kits, and the one that's "only" $670 is sold out (the other is an eye-watering $730), and they aren't on the QVL for any X570 board that I've seen, I don't relish the thought of being a guinea pig on this one.(if it were just $250, then sure).
FWIW, I've been leaning towards the Strix X570 E/F, and Aorus X570 Ultra/Master. Haven't settled on which one yet, especially because of the BIOS shenanigans ASUS played prior to launch, and their "ASUS Aura" software opening a hole in people's firewalls without asking.

Check into using Crucial Ballistix memory.

Ugh. Set up Nicehash, while running, it runs the CPU cores (all 12 threads) at 100%. Then, the mouse cursor stutters, pages don't load in the web browser, etc.

Seems I might be throttling.

In the newest (for 3rd-gen Ryzen CPUs) Ryzen Master software, it shows the temp as 94.75C with 95C max.

Probably throttling.

The heatsink that these things came with (3600) is utterly inadequate. I'm a bit pissed that so many reviews gave a positive word to this 65W TDP stock heatsink, when the 3rd-Gen Ryzen CPUs don't even stick to TDP. (Even when NOT manually OCing.)

AMD would have done much better by people, had they included the 95W heatsink with these CPUs, like they did the R5 1600 CPUs, back when they were released, so that you could actually OC on the stock heatsink some.

I'm not asking for OC, only that these chips have an adequate heatsink, such that they don't throttle at stock.

Edit: Package power says 77W. Heatsink is 65W TDP. You do the math.

CPU is at 3.8Ghz all-core.

Edit: Enabled PBO, after putting on 95W TDP heatsink, not sure that there's that much change.

Have you double/triple checked the seating of the CPU and thermal paste ??

5 bucks says it isn't seated correctly. Ran into this with a 2600X build.

 

[VirtualLarry]

Well, I had to re-do the screws around the heatsink a few times, sometimes one of them doesn't catch. When all four bottom out, though, it's attached correctly. As far as thermal paste goes, I just threw a dap of MX-4 onto the center of the CPU, and when I took it off, it seemed adequate coverage. I didn't clean the prior paste off of the heatsink, but visually, it didn't seem like there was much of any on there.

Anyways, I cleaned off the CPU, grabbed a 95W 1600 heatsink out of a box, and cleaned the thermal paste off of it (there was a weird off-color stain in the paste and copper core, like something liquid had dripped in, but the box was mostly sealed), and then applied fresh MX-4 to the CPU (half pea), and then attached the heatsink, all four screws bottomed-out.

So, right now, mining, temps on CPU according to Ryzen Master, are 86C. PPT is 87% of 88W. Clock speed is 3.88Ghz.

Edit: I switched from mining, which makes the entire machine especially Firefox Nightly to become unresponsive (not responding for like 2 minutes, to a click), to running BOINC, PrimeGrid (since I couldn't get WCG to give me tasks), and running 90% of CPUs (10 threads) of CPU crunching, and 2 threads (2 RX 570 8GB dGPUs) crunching GPU tasks, my Task Manager CPU graphs are all pretty-much filled, and Ryzen Master was reporting, briefly, temps slightly ABOVE 95C, when it lists 95C as "max". :|

Also, HWMonitor reports clock speeds of 3.75Ghz, at those temps and loads. This is with PBO enabled.

 

[VirtualLarry]

5 bucks says it isn't seated correctly. Ran into this with a 2600X build.

I don't see how all four screws could bottom out, if it wasn't seated correctly.

Remember, the CPU was drawing 77W. If the heatsink is only rated for 65W, that means that the temps are simply just going to continuously increase, because the heat output exceeds what the heatsink can dissipate.

 

[Head1985]

I want upgrade to 3700x but i cant.Not single 3700x/3800x/3900x was here in czech republic at launch and so far first batch didnt arive.This is probably worst cpu paper launch from AMD ever.

That also 'looks' odd (drawing 77w at stock), as why would AMD purposefully cripple their CPU by selling it with a heatsink that is 'overwhelemed' from the get go.

Re your method of attachment, all sounds good. Can you count the amount of turns you apply to each screw to check if they 'bottom out' with the same number of turns ?

 

[Monk5127]

OCUK is taking orders. No C8H so went for the Aorus Master and 3900x. Roll on Tuesday.
Suppose I should check some reviews now.

3900x should arrive today.
Motherboard ended up on back order and have managed to source one elsewhere, few £ more but I am impatient to get the new build going.

 

[VirtualLarry]

That's a "mining load", btw, not "idle", or "gaming load". It's pretty tortuous.

Not what was planned and, possibly, quite part of the issue with crazy thermals and less-than-expected power draw in some applications.

No lots of confusion. Via had nothing to do with it. Asmedia was sold the rights to develop AMD's desktop chips. Asmedia wasn't going to have a PCIe 4.0 chipset out till late this year or next. So AMD took the chipset they were going to use for EPYC (meaning this should be a rather stable chipset) for the higher end chipset so they had something to launch the CPU with. Maybe to a degree it was always the plan. Now there are reports that the chipset is basically the 3k IO die re-purposed. But the power usage is because it was a chip meant for a server implementation and not a desktop one. It's still using less power then it would on EPYC (11w vs 15w) but its only 4w more than then x470. It isn't some super crazy power usage its just a little bit more then they feel comfortable with just a HS and no fan.

So, what are the chances of four 16 GB DIMMs running at 3200? Will it have to drop down to 3000 or do you think they'll be fine at 3200 but with looser timings?

I had toyed with going with four 16 GB DDR4 3200 CL14 DIMMs in the 8700K rig in my sig but thought they'd likely have to drop down in speed to work well. Is the 3x00 series able to accomplish full speed on four DIMMs? I am inching closer to building a new box in late summer/early fall. My current server (dual E5-2620s, 256 GB of RAM, 40 TB of storage) is over capacity and I was thinking about a 3900x, 3950x, or even a Threadripper to build up a high-core count machine where I could use some additional VMs.

I don't think the timings will be terribly important for your workload to be honest. As you can tell from my sig, I've got some CL14 memory in two of my machines because I wanted the best timings available but to be honest, if I had it to do over again, I would've saved $100-$200 and just gone with CL15 or CL16. Of course, I also bought that 32 GB CL14 kit when RAM prices were still high, but I didn't have a choice as I really needed it.
