Switching from 2 sticks of b-die to 4 sticks was/is an adventure. I never knew how easy I had it with 2 sticks until I tried 4. I won't go back, but the 2 stick easy tweaking will be missed.

4 sticks defaults to gear down mode. Trying to run with CR1 and GDM disabled is unstable. So far it's looking like CR2 is the lesser of 2 evils when it comes to effecting latency. I'm still playing around with the memory, but I'll settle for 3600 CL14 if I have to.

Welcome to my world :D

I'm just happy ive found my CL14 memtest 1000% stable settings with 4x8gigs @ 1900mhz IF 1:1

If some of you other guys want to start playing around with the curve optimizer, i can recommend this as a starting point if you are using a Asus motherboard:

Make sure you have Global C-state Control disabled in bios before you start.

In Extreme Tweaker:

  • PBO Fmax Enhancer: disabled (dont work with 5000 series)
  • PBO: manual: 280/235/245
  • Overdrive: +50 mhz
  • CPU SoC voltage: Manual 1.08 -1.10v
  • CPU Core Voltage: Offset 0.01 -0.06v (You want the least amount of offset as possible. Most will be @ +0.05v)
In Digi+
  • Max all the current limits
  • Disable all the spread spectrums
  • SOC LLC: Level 3
  • CPU LLC: Level 1 or Level 2
Note: You want the all core voltage to be as low as possible to get the highest all core boost that you can. My logic here is that I am using core voltage offset to maintain enough voltage for a stable single core boost, but the lowest LLC so that on all core loads the core voltage will droop and allow a higher all core boost clock.

In Advanced> AMD Overclocking > PBO
  • Set to advanced
  • Set limits to "Motherboard"
  • Curve optimizer: All core, Negative, 15-25 (can start at 15 and work your way down to 25 if system is stable)*

If you have a 56/57/58/5900X You use the same settings but increase the overdrive setting from 50mhz to as high as your single core test will allow. Most CPU's will max out at a sustained 5050mhz and 5125mhz single core boost.

To test single core boost clock:

  1. Open HWinfo64, make sure you have the "Effective Core clock" registers exposed.
  2. Make a note of the top 4 ranked cores.
  3. Open task manager and to to the "Details" tab.
  4. Open CB R20, start a single core run
  5. In Task manager's details, right click Cinebench.exe, click "Select Affinity", uncheck the top box to de-select all cores, put a check box next to core 0, then click ok. (You will have to re-select the affinity every run unless you have an application such as Process lasso that will automatically apply core affinity.)
  6. In HWinfo, Look at the clock speed for core zero. It should be at your max boost + overdrive (for a 5950X using the settings above, that would be 5050mhz max boost + 50 mhz overdrive = 5100mhz).
  7. In HWinfo, monitor the "Effective core speed" It should be very near reported core clock. For example, the core clock is at 5100mhz, the effective core clock should be 5085mhz or higher. Generally effective clock will be reported a bit lower than core clock because of how it is calculated. (which is why the effective core clock really needs a sustained load to be close to accurate).
  8. Monitor Core voltage and effective core VID. Your core voltage should be 1.5v- 1.525v, and effective VID 1.485v - 1.506v. You really don't want core voltage to exceed 1.525v for sustained period (spikes are fine and normal) This is why your core voltage offset shouldn't exceed +0.05 - 0.07v.
  9. You should be able to complete at least 5-6 back to back runs of CB R20 without crashing.
Once that is done, you move on to the next three of the top rated cores and make sure they are stable. Though it is likely that not all of the top four cores will boost as high at core 0.

Once that is complete move on to all core load stress testing. If an all core workload does not pass stress testing, increase core LLC to achieve stability.

*edit*

* = You can start with -15 on core optimizer with cpu voltage on auto, then work the negative curve offset down until you have all core instability, or until the all core boost clock stops increasing. There is no point in running the neg curve value beyond whatever gives you max all core boost..

Once you have your all core set to highest stable neg offset / highest all core boost clock, Move on to single core.

Open cinebench and open task manager. Start a single core run, then on task manager's details tab, find cinebench, right click and set cpu affinity. Leave only core zero checked.

In hwinfo, click the clock to reset the counters after the single core run starts, and after you set cpu affinity. Then monitor the core 0 effective clock. It should be very close or the same as core frequency.

If the run fails, Start adding positive cpu core voltage offset to get your single core stable.

Once done stability test with IBT linpack on very high/high for 10 passes, Blender Benchmark (all scenes), 1 hour of P95 blend with AVX disabled.

Has anyone said what will be the effective max power draw for any of the announced Vermeer SKUs? Matisse topped out at 142W.
The Anandtech article had a blurb on that. "All four processors have the same official memory support at DDR4-3200, and the 105 W TDPs will offer a turbo power of 142 W, which is the same as the current generation Ryzen processors."

I currently have a 2600X and a MSI B450 Tomahawk motherboard. I’m planning on upgrading to the 5600X and I have 2 options. Option 1. I wait 5 to 6 months and upgrade the BIOS on my B450. This is the cheapest option at $300, but I don’t like the idea of the one direction beta BIOS update. The second option is to buy a B550 or X570 mother board. This option would cost me around $500, but I have no idea which type of board to get. I’m a little surprised at how many B550s cost more than a X570. I’m looking at boards in the $200 range. Something like the ASUS ROG Strix B550-F Gaming (WiFi 6) or the GIGABYTE X570 AORUS ELITE WIFI.

I'm somewhat surprised so many people are surprised that 5800X is hot. It's a 105W TDP part (the max possible on stock on AM4), with a single chiplet. So unlike 5900X and 5950X the TDP is not split between two chiplets, unlike 5600X one chiplet is not limited to 65W TDP. With that added headroom 5800X is bound to be running at the border of the thermal envelope. If people expect/want it to run like the other three chips I'd suggest lowering PPT or use eco mode.
I want to add that the heat is inherent problem of the 7nm process, For example Zen3 in eco mode (65W TDP) will still boost to 5+ GHz and cause temperature spikes. Eco mode is targeting PPT, whereas per core temp could still spike due to a single core boosting to oblivion.
On the bright side, you dont lose ST performance in eco mode, and if the fan noise is bothering you, you can alter the fan speed profile because according to AMD Zen3 should be perfectly fine working around 90 degrees celsius daily.
5800X is particularly very boosty in ST, but since it is not as highly binned as 5950X it uses more voltage to reach the higher speeds and therefore cause higher temperature spikes.
During all core loads, surprise, the temperature actually does not spike. This is my observation so far.
But Zen3 has a much better temperature curve than Zen2 for sure.

Damn! Your RAM is clocking well! I guess you are running 2 sticks?
I made my set of Samsung B-Die stable at 3840MHz CL18-17-16 and the rest of subtimings tweaked, but my best latency was 56.8ns and 56GB/s Read.
Yep! and yes I'm only running 2 sticks. I'm thinking my kit was produced during the crazy high DDR4 pricing and wasn't really binned well, if at all....I wouldn't min

Can your kit do 3600 CL14? With tight timings you could shave off a couple ns's and not lose any bandwidth....Viewing my 3600 CL14 snip a couple posts above for reference.

What kit do you have? The dual rank 32GB one?

I had once feared that the 3900X would offer up serious VRM problems for cheaper boards, but that threat never really materialized. You had to hit pretty low on the AM4 motherboard list to find VRMs that would really overheat with a chip like that in the socket. It was possible, but rare.

The 5900X isn't going to be any worse.

edit: Looks like the B450m Pro4 has a weaker VRM than the B450 Pro4. As long as its cooled you should be fine.

It really depends on ones work flow, case air flow and ambient temps of room.

I guess a person could reference some of the Hardware Unboxed videos were he does somewhat push the higher core offerings. I'd imagine the 5xxx series would have similar results.

A couple of snips of B550's and X570's for quick reference. The higher end boards usually have the best temps.

B550 VRM temps.JPG

X570 VRM temps.JPG

I view the above examples as most likely not even the worse case scenarios.

By the way, it turns out that the other memory kit is likely defective. I don't see any other reason why this kit boots just fine but the other one doesn't. I did the previous single and dual stick test with that kit... Then I swapped the positions and tried first with single stick from another kit. Then I added another stick from that kit.

Done tweaking my final 24/7 PBO + curve optimizer settings.
Had to handtune the curve optimizer setting for each core on my cpu to make it 100% stable and boost like it should, and it took pretty much whole day, but it was worth it in the end :)

Screenshot below show the curve optimizer offset for each of the corresponding cores in ryzen master.
Hwinfo's T0 effetive clock show what each core can sustain in cinebench r23 singlethread with these settings. (forced the thread around by affinity)

finale 24-7 PBO settings.png

Also did a 1000% memtester run to make sure my memory settings are rock solid.
memtest 1000 24-7 settings.png

Pretty much done tweaking this platform now.. Just waiting for my RTX 3090 SUPRIM X to arrive next week so i can start playing around in 3dmark :)

*edit*

Some benchmarks with my 24/7 settings:
24-7 settings.png
Note: Passmark runs really hot, had 82max temp after cinebench r20 and r23 multicore with passmark upping it to 90 (!)

people on other forums complain about WHEA error.. windows event viewer-> windows logs -> system

I get them aswell when i overclock my memory, but the system is stable.. tested 5hours + in ramtest.. so continue to run it overclocked..

i think its a bios problem.. but some people already talking about RMA..

What you guys think? We got bad CPUs? Or it just a bios thing?
One thing to keep in mind is that Zen 2 and Zen 3 only officially support up to DDR4-3200 memory despite motherboard manufacturers mentioning their motherboard's support faster RAM, for example, DDR4-3600 (OC), DDR4-3800 (OC), DDR4-4000 (OC), and so on. (OC) is mentioned in those specs of the motherboards because those speeds are not officially supported by those CPU's. If you run faster than DDR4-3200 RAM on these CPU's, don't expect it to run stable, as that's technically an overclock. I'm not surprised that some people here are saying that they are getting WHEA errors when they are running faster memory than what their CPU's memory controller officially supports. I would not blame that a CPU is defective if it can't run faster memory reliably that what it officially supports and I would recommend running the memory within official specs of what the CPU supports and see if those WHEA error still happen before blaming a bad CPU.

I performed an exorcism on my PC the other day and removed the evil Nvidia card. I had to wait for my memory sticks to arrive before I would post a photo. I'm still working on a color match for the memory and the RX on the GPU.

20201215_125230.jpg

Parts list:
AMD Ryzen 9 5900x
MSI MPG B550 GAMING CARBON WIFI
G.SKIll Trident Z Neo 32GB(4x8)
XFX-Speedster MERC319 AMD Radeon RX6800
Samsung 970 EVO Plus SSD 500GB NVMe boot drive
Samsung 860 EVO 1TB storage drive
Lian Li PC-011 Dynamic
Corsair iCUE H150i Elite Capellix AIO
Corsair QL Series, Ql120 RGB,120m(3-pack)
SEASONIC FOCUS+ 850w

Assuming Zen 3 mostly lives up to the expected IPC increases I'll definitely pick up either a 5900X or 5950X and do some shifting around with my current builds. I'll likely pick up an AM4 mini-itx board and push the current 3900X over to it and replace the 6700K.

I doubt it, we'd have probably seen a lot more leaks if so. We can hope for preorders maybe though after the reveal.
If AMD managed to ship Zen 3 products today (or hell even just this week) with wide availability it would be the most impressive thing about this entire launch. Not even Apple is that good at clamping down on leaks, so it would be even more impressive than anything else they might have managed to accomplish.

Earlier this week I found out my main system cannot play 4k video smoothly, so I'm thinking about picking a new system with a non X version comes out.

I've been thinking of building a small form factor PC for a while now. The 5800X would be perfect for this.

I'll probably be looking at slotting a 5800X into my current X570 MB with a 3080-class GPU and a new RAM kit. My current 3600 and RAM will move over to the wife's computer to replace the aging 2500k.
