AMD Ryzen 3000 Builders Thread

[EightySix Four]

Finished my first build in quite some time this week:

• 3700x w/Noctua NH-L9a
• 32gb of 3200C16 RAM (E Die, may try and drive this to 3600 at some point)
• X570 I AORUS PRO
• MSI 2060 Super Ventus OC
• DAN A4 (7.2l micro case)

I'm not really chasing the absolute maximum from the CPU in such a small case with poor thermals but with a 75w package power restriction it stays at a reasonable temperature under load and still boost to ~4.3gz with single core benches.

At idle with the latest Ryzen Balanced plan I regularly see <.8v according to Ryzen Master and I have basically no fan noise.

I have to say I'm pretty happy with it so far.

X570 I AORUS PRO

How's the (chiset) fan speed/noise on this board?

 

[EightySix Four]

How's the (chiset) fan speed/noise on this board?

I don't think I have heard it - at idle the system (sitting on top of my desk ~2 feet from me) is essentially silent, doing anything more intensive means the cpu/case/gpu fans have spun up and are louder than it must be.

Tweaked my timings a bit

Updated My Asrock X470 Taichi Bios from 3.46 Beta to 3.51 Beta. This is with no overclock or PBO on the CPU besides bumping FCLK to 1800Mhz and RAM at 3600Mhz.

How's the (chiset) fan speed/noise on this board?

I don't have his board, but I can tell you that the fan noise is pretty low with stock fan settings on an x570 Aorus Master. Chipset sits around 46C with all the case fans going. Taking the side off my Thor v2 (with the massive fan) raised temps on the chipset fan by about 6c.

edit: I've observed an odd phenomenon when attempting to tune RAM using 1usmus' Ryzen DRAM calculator and Ryzen Master.

I created a timing set for DDR4-3733 Fast, plugged in the timings, and . . . failed to boot. So I lowered speed to DDR4-3666, got a boot, and got terrible performance. Setting speed down again to DDR4-3600 allows it to boot and perform normally. Got 66.2 ns latency, etc. So, what gives? I understand the instability, but why the poor performance? Just another feature of running RAM too close to the razor's edge?

Some more data:

After tuning my dGPU (Radeon VII, 2050 MHz, 1200 MHz RAM), I ran The Division 2 in 1080p medium to see how PBO and static overclocks would affect clockspeeds.

default


PBO


4300 MHz static


4375 MHz static


Note it reads "custom" since I turned off vsync. Everything else in 1080p medium.

3DMark Firestrike:

In conclusion, PBO is worthless on my machine for . . . nearly everything.

 

[Pandora's Box]

Some more fiddling this morning. Decided to try setting LLC to "Auto" instead of Level 3. I tried levels 1-5, all lost performance over auto...

Auto had all cores locked at 4100Mhz, with an occasional boost to 4150Mhz while running cinebench R20

I find it slightly amusing that the best performance on this 3900X is to leave everything in bios on Auto, set FCLK to 1800Mhz, and overclock your ram. Gone are the days of tweaking other settings imo.

Isn't base clock 3800MHz? My 3700x boosts to 4150MHz during CB R20 all core, on air, at default clocks. 4375MHz during single core.

Gotta test 3700x more as I did a fresh install of Win 10 late last night.

Tried PBO with 3600 in same MB. Looked worthless to me at that time.

That's what I've found with my 3600 too!

Not on mine. Wonder why you're getting such a high score @ stock?

I did a throwaway run at 4375 MHz:



I've had it as high as 7812 before. That was with RAM running only defaults since something got goofy after I spent awhile playing video games (CBR20 didn't want to perform well, but everything else was okay, go figure). Maybe I need to stop using Ryzen Master for memOC.

Isn't base clock 3800MHz? /QUOTE]

Yeah, I'm not using base clocks on static OC. Just showing how static OC is actually faster in nearly everything, at least on my setup, compared to PBO or stock. PBO is supposed to be faster in games, but it isn't.

I do not see any clock information in the results?

I've had the best performance with bclock overclock. Not very stable, though. I have been wondering why overclocking bclock seems to beat whatever limitation AMD imposed on this chip.

So my X570 Gaming Edge WiFi fails to power up with my 3600 in the socket. Powers up perfectly fine when no CPU in socket.


Any suggestions as to why my CPU would be tripping motherboard power?

1st time booting up? Reset cmos? No signs of life at all with cpu in mb?

Also, the very first time with a new CPU, sometimes takes like 5 minutes to post !

 

[PotatoWithEarsOnSide]

Yup, first time trying to boot. Whenever CPU is in socket it just won't power on the motherboard. No EZ Debug lights etc...no fans...no power. I swapped out the CMOS battery, but still nothing.

There's just no sign of life at all.

Power supply is working fine. GPU lights up when no CPU in socket etc. It just trips as if there's a short circuit with CPU in socket.

Only thing I haven't tried is without the M.2 SSD. I've read that my board doesn't like SATA M.2 SSD in the primary slot, which is weird.

Try removing and see.

I always boot new combos out of the case to make sure they'll boot up.

I would double-check if that slot is PCI-E -only, and if so, certainly don't plug a SATA M.2 SSD into it. Maybe that's the problem?

Question about upgrade paths.

I'm currently sitting on my placeholder GB B450 DS3H, 2200G, 16GB CL16 3200 o/c to 3400 G.skill Trident Z RAM, and have been trying to figure out the best path forward.

I do plan on grabbing a third-party 5700, as my son and I enjoy some casual X-Plane, Rocket League, Cities:Skylines, Fortnite, and PUBG. I think that's the easy choice.

My harder decision is how far to go with the upgrade on the CPU. I also use this PC for photo editing (GIMP, DarkTable), data analysis (Excel, R, JMP), Plex server, and use it for my work (which involves some poorly optimized electronic medical record software - all of it is unoptimized, there are no other options - as well as Excel and some propriety financial software).

I had originally planned to make this simple and get the best bang for the buck with the 3600, but I wonder about two things: future-proofing and whether I might hit some limits. I figure 6C/12T would probably be enough now. But as my son grows older and his gaming interests diversify, and looking 2-3 years into the future, I do see the possibility that not just gaming (+/- streaming) but also the above hobbies and work would benefit from going with a 3700X or even a 3900X.

The questions are:

- will I encounter any obvious issues with a 3700X or 3900X (stock) on the DS3H?
- is a 3900X substantially more future-proof than the 3700X?
- what would you do?

The easy path out is to just toss/sell/repurpose the mobo and CPU - and make this a badass 3900X, ASRock X570 Phantom Gaming ITX or Aorus Pro Wifi X570, and a third-party 5700.

My gut is to do a total upgrade, but my brain says I should at least explore whether a 3700X and keeping the DS3H (with the 5700) might not be a bad idea, and save $219 + $170 = $389.

- is a 3900X substantially more future-proof than the 3700X?

That's a mid/low-end mATX board, right? Any heatsinks on the VRMs? How many phases? More than 4+2?

Ideally, CPU-wise, forward-looking, I would go with the 3900X, if you can afford that. I don't know, though, that I would put more than a 3600(X) into that board, due to VRM issues.

One thing that may not be immediately obvious, is that the 3900X is made from two 8-core/32MB L3 cache 7nm CPU dies, so you get 12C/24T, but also, TWICE the memory write bandwidth, and DOUBLE the L3 cache of a 3700X or 3600(X).

Those extra capabilities may prove useful for some applications, and maybe streaming, if he doesn't use the GPU exclusively. (Or possibly, even with the GPU, as the memory-controller is on the I/O die in the CPU package, and the PCI-E from the video card has to write to RAM through that, so if the pathway is 2X as wide... have to research that, I guess, if the doubled write bandwidth applies to PCI-E devices or not.

The other thing to consider, is a RX 5700/5700XT, with PCI-E 4.0, and a PCI-E 4.0 NVMe SSD, to optimize platform-level performance. This, of course, really requires an X570 mobo too.

So, maybe, just get a $200 3600 to start with (they're worth it, even at the lower-end), and as you get used to 3rd-Gen Ryzen, consider the "full upgrade", 3900X, X570, RX 5700(XT), and possibly a PCI-E 4.0 NVMe (though they are quite pricey right now).

 

[DrMrLordX]

I do not see any clock information in the results?

Yeah there wasn't any. The online browser provides some. There were boosts into 4550-4625MHz on some of the tests. Point being, even with the boost behavior, the static OC wins anyway. For whatever reason, the combination of the microcode and Win10 scheduler can't keep enough cores boosted high enough to compete with a simple 4.3 GHz OC.

The only application where I've gotten better performance out of stock (not PBO) is SuperPi 1.5 mod xs. And I had to set core affinity to make that work. Plus cross my fingers. Sometimes it doesn't want to play ball!

I've had the best performance with bclock overclock. Not very stable, though. I have been wondering why overclocking bclock seems to beat whatever limitation AMD imposed on this chip.

block OC worked with Ryzen 2700x as well. Problem is that overclocking bclock can freak out some NVMe drives. I haven't explored that yet on my end.

Yup, first time trying to boot. Whenever CPU is in socket it just won't power on the motherboard. No EZ Debug lights etc...no fans...no power. I swapped out the CMOS battery, but still nothing.

There's just no sign of life at all.

That's exactly what I got when I plugged in my first 3900x . . . after I lapped it.

- will I encounter any obvious issues with a 3700X or 3900X (stock) on the DS3H?

Possibly. That isn't a lot of VRM phases. A 3900x will run, but those VRMs . . . anyway you will want to apply a negative voltage offset to keep power draw down. Personally I have not had many situations where the CPU pulls more than 110a, and I have seen how stock behavior will halt sustained current draw at 95a pretty reliably, so in theory, it should run "just fine". In practice you will lose clocks versus someone who has even a basic 8+2 VRM setup. Maybe -100MHz. Of course, you can always upgrade the mobo later. And you can avoid PBO since in most cases, it seems universally terrible on a 3900x.

The real question you should be asking is, "can this motherboard push 95a @ 100c VRM temp all day?". If the answer is "yes" then you will be fine.

- is a 3900X substantially more future-proof than the 3700X?

Maybe, maybe not. It's all about the extra cores. A 3900x isn't that much faster clockspeed-wise than a 3700x . . . certainly not to the point that it is more future-proof. I think I can sustain clocks maybe 200MHz higher than the average 3700x user, and I had to put on massive cooling to accomplish that.

The software world is just now getting to the point where casual gamers/application users might really want 6 cores instead of 4. 2-3 years from now, maybe we'll see 8-core as the minimum. 12-core CPUs? With SMT? Nahhh.

- what would you do?

Save money, get the 3600, and watch out for Zen3.

The easy path out is to just toss/sell/repurpose the mobo and CPU - and make this a badass 3900X, ASRock X570 Phantom Gaming ITX or Aorus Pro Wifi X570, and a third-party 5700.

You would save more than that. If you really want a 3900x system to be "badass" then you have to look at cooling. These chips are insanely hot. Someone who figures out how to integrate an ambient TEC into an AiO or waterblock will make a ton of money off 3900x users.

When I build a new combo I just go for the basic cpu, mem, video card on top of the box to make sure it works before I go thru all the hassle of mounting it in the case and tidying up all the wiring, etc.

I wouldn't rule out a short or crossed motherboard lead, incompatible usb header, etc.
