AMD Ryzen 3000 Builders Thread

[IEC]

Regarding idle voltages and idle temps.
1) These chips are on 7nm, and have a tiny die surface area (~30mm^2 for cores per chiplet!). This means even at iso-power, the thermal density is much higher versus the comparable 14nm chip = observed higher temps and hot spots. Can't beat physics.
2) The chip clocks up and down in 1ms intervals under the new Ryzen power plans introduced with chipset driver 1.07. The behavior of Ryzen 3000 series is to "race to idle" meaning it clocks up as quickly and as high as possible to complete a task in order to finish it using the least amount of total energy possible. This means that you can observe very "spiky" voltages and temperatures. This is *normal* and expected behavior. This also means that your software you are using to capture clocks and voltages is likely only correct for a millisecond snapshot (if that) and doesn't reflect the true clocks or temps of your chip. If you aren't seeing 1.49V+ and you aren't thermal throttling, I wouldn't worry about it just yet. I have yet to thermal throttle even on extended AVX2 loads.

Now that said, BIOSes are definitely immature and there are a lot of bugs (boost clocks, IF desyncing beyond 3200 on Auto/XMP settings on non-X570 boards, etc) that need squashing, but I'm sure the low-hanging fruit will be addressed within days if not weeks.

If the thought of waiting a few weeks nauseates you, I would recommend you wait for a sale (e.g. Black Friday) before you upgrade. Not only will you save money, you'll probably get some nice performance boosts over launch day reviews from the improvements coming over the next few months.

That same kit was on ebay the other day for $129.99, sold by Newegg. I ordered one, and they canceled it stating that my address was invalid.

That sounds like what NewEgg will pull out when it thinks it can get away with.

Many people are reporting high idle voltages or voltages stuck at some high value(1.4V or higher) despite following the steps Robert Hallock said to follow. So there's more to it than just quirky power plans.

I have a MSI b450 tomahawk and 3900X
so far only one strange thing I experienced is pretty basic- with wraith prism (yes I plan a better cooler) and default setting while playing Dragon age:Origins a 90C temperature while low rpm on the cooler- pretty basic stuff to regulate
then after alt tab and back and RPMs went up and temp down
strange is that game pretty much uses 1 thread
never experienced this with any workload tested on the new setup (excel, handbrake, witcher 3, some older fortran codes, prime 95)

What's the best monitoring software for ryzen?

Using cpuz to monitor vcore I've seen my 3600 drop down into the high .4's low .5v's while watching ryzen master putting multiple cores randomly to sleep.

for Ryzen 3000 series, I think its been said that Ryzen master is the only way to go.

Up and running. Will see how it goes. Must say I'm disappointed in Newegg. The 3900x and the CVH8 Hero wifi has a $20 bundle discount. Newegg didnt give it to me. the offered a 10 gift card. From now on i may get my mobo and cpus from my local Microcenter since they seem to offer better discount on bundles.

Anyway cpu temps seem to hover around 40 to 50 c according to Asus monitoring software. We will see how this puppy runs the next couple of weeks.

Running 16GB of Gskill ram. Anyone think running 32GB of ram would be better?

Did you add the combo to the cart, was it showing in the cart, or did you add them separately, and expect them to give you the bundle discount (doesn't work that way).

4x8GB Samsung B-Die @ 3733 CL16 (Auto subtimings):



So far so good on passing memory testing. I'll let it keep going overnight.

I thought I had aida643 installed, but I am having a problem finding that benchmark to try on my 3900x

 

[Snarf Snarf]

@IEC are you running 1:1 IF clocks with 3733?

 

[IEC]

@IEC are you running 1:1 IF clocks with 3733?

Yes, those latencies are only possible at 3733 MT/s if you are running sync @ 1:1

FCLK 1866

 

[Markfw]

Something is seriusly amiss with my ASRock 3900x. I think the bios is crap, or maybe I need to reflash ? Its speed it like 10-20% worse than my ASUS X470 prime pro. It does 515/7014 on cinebench 20, and the ASRock does 465/6300. Also, the latency is 127, and it locks up all the time (it comes back eventually) Something is seriously wrong with it.

Help ! Bios defaults, except 3200 memory settings. Its 3600 cl15 memory, but if I set it to 3200 it says it matches the fabric speed in Ryzen master.

Edit: and aida64 says something about unrecognized cpu, and not optimized for this cpu.

 

[EXCellR8]

Uh oh, sounds like ASRock should release another BIOS for that board...

 

[Snarf Snarf]

Very nice, these are my results after using 3600 CL16 kit optimized with Ryzen RAM Calculator.

This is your Asus X370 board? Be happy that these first 3rd-Gen BIOS releases for older-chipset boards even boot properly, IMHO. Performance should be secondary to stability, and ASRock isn't exactly known for AM4 BIOS stability. One of the reason that I ditched my AB350M Pro4 boards. (Which, apparently, will run 3rd-Gen Ryzen CPUs, which to me is bizarre, as I had a mountain of problems just getting them to run 2200G APUs properly at all, without boot issues.)

Edit: Oh wait, your board is Asus, I went on a rant about my ASRock. Sorry, mental glitch.

No, I have an x370 ASRock (dead right now, no compatible chip), and x470 ASRock (the problem child with 3900x) and an ASUS x470 (seems fine) with a 3900x.

So its the ASRock with the 3900 that is a problem. I reflashed the bios, its running win 10 1903, and I have the 1.0.0.7 (I think thats it) chipset drivers from AMD and some drivers that ASRock mentioned on the bios update. ALL installed, no problem ,

But there is a serious problem,

SoC Voltage is at 1.1, DRAM voltage 1.45

You're honestly not alone, my x570 Croshair VIII Hero is doing an absolutely terrible job of boosting and managing voltage at full stock settings with latest AGESA and AMD Chipset Driver. No single core boosts over 4.2 and ACT is 4.1 regardless of PBO settings. Currently running manual OC to 4.3 at 1.29V and my ST/MT scores are considerably higher than at default BIOS settings on 360mm Rad.

I should add, both the 3900x systems are on identical coolermaster 240 AIO's. The ASUS has 4233 GSKill bdie cas 16 running at 3600 cl 15. The ASRock has 3600 bdie running at 3200 cl16

This is not about boost, its about stability also, its rebooting like 10 times. and locks up (temporarily) for like 2 minutes, all the time. Its really unstable, and it was NOT with everything the same except it had a 2700x in it. Its the bios. it sucks. 3.43

Nice!

I'm still playing around with my b-die kit. I didn't go all hard core into the sub-timings yet, but so far so good it looks like.

Nipped ya by a ns!

You guys all think you're so cool with your processors that arrived on time... i ain't even upset

Well, I was going to wait till black friday sale at Microcenter, but they had open box 3700X for $280 and I got one along with $50 off motherboard. I'm running it with Asus X470 Strix-F in my fileserver under Windows Server 2019. Cooler is Scythe Ninja 4 with a single Scythe GentleTyphoon AP-14 fan. Running two instances of ffmpeg to fully load all 16 threads it boosts to roughly 3.9-4GHz on all cores, temp is 65 degrees C, CPU fan is spinning at 1350RPM.

Like others I have problems with high idle vcore. This being Windows Server 2019 install I only have access to Balanced and High Power plans. On Balanced Plan my 3700X (just like 2700 it replaced) does not boost to proper frequencies severely handicapping my ffmpeg encodes. On High Power plan it boosts just like it's supposed to, but in idle it stays at >4GHz with vcore of 1.4V. Dumb. I'm going to try to install Chipset drivers from windows 10, hopefully they'll work on windows server 2019.

Obviously a little concerned about high idle voltage, but otherwise very happy made the switch, the 3700x is noticeably faster at x265 encoding compared to 2700.

 

[GhostPirateLeChuck]

Yeah, I know. Sigh.....

Seriously considered the Asus X570 workstation board but it has limited SATA ports and I may need 8 SATA ports. Considering using this as a machine to host my workstation VMs along with some SQL VMs to take the load off my primary server. I like the idea of populating it with those 32 GB DIMMs.

I hear ya on the 32GB DIMMS. I won't be running server loads per se, but the VMs I do use (and the number of instances) can be very resource hungry, core and RAM wise.

If you aren't wedded to the idea of needing 8 sata ports, that aorus master does have 6 sata ports and 3 M2 slots, and you only lose sata ports if you use the 3rd M2 slot.
