Been playing around with the zenpower driver and zenmonitor app again. I looked at them back in Ubuntu 18.04 but I wasn't running a sufficient kernel. Now that I am they are pretty useful as a replacement for the k10temp driver. Shows more stuff. Interesting that the Vcore doesn't quite agree between the SIO sensor reading and the SVI2 sensor reading from the cpu. The actual Vcore is a few millivolts higher. You get readouts on the individual CCD's too. Would have liked to have run this against my 3900X with the one good, one so-so CCD dies to see how much differential there is between good dies and lower binned ones. The other benefit is the power readings.

No it will work on the latest Ubuntu 18.04.4 HWE kernels and that is only when you are running Ryzen 3000 cpus. Works fine on Zen1/Zen+ without issues. No problem running it on both the Ryzen 3950X with kernel 5.4.0-31 kernel in Ubuntu 20.04 and on the Threadripper 2920X on kernel 5.3.0.53 on Ubuntu 18.04.4.

For AMD family 17h Model 70h (Ryzen 3000) CPUs you need kernel version 5.3.4

Just a FYI for those who have downloaded and compiled the Zenmonitor application. The 1.40 versions and earlier didn't report all the core cpu frequencies correctly on Threadripper.

On my 2920X, it only showed the last 6 cores of my 12. The first showed 0 clock speed.

The new https://github.com/ocerman/zenmonitor/tree/sysdet2 branch version 1.41 fixes the issue. Just download the branch and do another make to get an updated binary.

Another FYI, if anyone is considering changing over to a custom cooled system for cooling their Threadripper, I can heartily endorse the Absolute Threadripper3+ cpu block.

They are getting caught up in shipments now with Covid-19 restrictions being removed. I got my block back in May and have been using it with great results. The block is the best in the market currently on performance. I dropped 10 degrees at least from the XSPC Raystorm Neo block I was using.

They just shipped me a brand new updated design acrylic insert and mounting studs and nuts for free as they discovered even more performance possible with a change in the insert bow.

Supposed to add another 1-4°C. temperature drop to the already excellent temps I am getting. The new insert design and mounting studs are standard now.

For example, I am currently running my 2920X Threadripper at 4100Mhz and 90% cpu core utilization and getting between 58-62° C. temps all the time under an all-core overclock.

One Optimus TR3 block user in the OCN Optimus forum already updated his block with the new insert and gained another 1-2° C. temp reduction from the original shipped design.

I haven't updated mine yet since I want to change to the Optimus Absolute D5 reservoir I am already using on the 3950X host. I want to have all the bits available to install since it means breaking the system down to put the pieces in. Just ordered another Absolute D5 reservoir for the TR host.

I stumbled around trying to find a really low cost Am4 socket cpu and ended up with an Athlon 3000. My mistake. I needed a version 1/2 Ryzen CPU not a version three CPU.

Once I got my latest X470 MB bios updated I got the Athlon running under Windows 10.

The claim that this CPU is "adequate" to run light office tasks and browse the internet is probably true. But for some reason a 2 c/4t with iGPU doesn't have a lot of "snap" :)

Anyway I broke down and bought a used 2200G to use for testing so I don't have to UN-install another version 2 CPU for testing every time I need to.

My recommendation is that even office workers should start at 4 cores any more. So probably you minimum as a 2200G or one of the those other 4 core 1st gen Ryzen chips with a discrete gpu.

First generation Threadrippers (especially 1950's) seem to be showing more and more on some of the BOINC projects I am participating in.

I have pondered if it its related to the high number PCIe lanes they offer which might support the possibility of more than 6 gpus? But so far most of them are showing a tendency to run 1-2 gpus. The one exception I know of for sure is Kevin O's rig which has been running 4 gtx 1080ti's forever.

Happy Thursday.

I have been gradually bringing Rosetta on line and am creeping up the charts. Noting that tasks use a lot more memory than Seti I have purchased 2 x 16gb same make memory sticks Corsair Vengeance LPX to match the 4 X 8gb already in the Threadripper 2990. Unfortunately this crashed all the tasks I suspect because the 16s are 3200 whereas the 4 x 8 are 3000 and it was making the overclock unstable. Tom suggested studying the BIOS and I did changing the extreme tweak on the ASUS ROG zenith extreme to auto auto. This solved the computational errors and it has been running for two days without any problems. Unfortunately throughput has nosedived so I assume we are back to running at base clock frequencies although I havent been back into the BIOS to investigate. The temp has also dropped by 10 degrees!
I am leary of fiddling too much in the BIOS so I would like somebody who has the expertise to guide me on a step by step basis to force the system to operate at the 3000 level . I appreciate that it would have been better to have all memory at the same frequency but surely you can force higher to operate a tad lower?
Hope you can help.

What brand/model of motherboard?

1) Examine your ram. You want to confirm its speed (3000?)and a string of timing #'s like: CL 14-14-14-34 1.35v
It turns out that not all the ram I own has this kind of information on the ram stick.
You need that information.

2) Someplace in the "overclocking" section of your bios, you are going to find a place where you can set the voltage (1.35v) and all the CL timings.
The ones I have posted are from a 3200 speed module.

Your goal is to set if for your slowest ram DDR4-3000 CL 16-16-16-36 1.35v?

You might be able to find an "XMP1" or "XMP2" profile that runs at 3000.

You also might be able to the "memory presets" that say 3000 CL-16-16-16-36

If you can find a memory preset menu that is exactly or only a little bit slower than you need that might take care of the problem(s).

The higher the CL related #'s the slower the chip.

HTH,
Maybe if someone has your make-model of the motherboard we can be more step by step.

I think the next time I want to buy an 8c/16t CPU I am going for a 3700x.

It will be more efficient than my 2600/2700 cpus and have as many threads as my 2700 does.

And it won't cost like a 3900x/3950x does.

The MB is as stated in my post :- ASUS ROG zenith extreme BIOS 2001 I think without shutting down system .
I would emphasise that I had the tweaks set perfectly for 3000 running when there was only the 4 x 8 sticks present and it was quad channel. It was when the 2 x 16 3200 was added that the tweak for 3000 running went awol. I did not alter the BIOS until there was obvious failure presumably with instability which is borne out by going auto auto which cured the instability but also zapped the overclock.

It is going to be very difficult to run two different RAM speeds when the first ones are single rank and the second kit is dual rank. Big differences in timings, and load resistances.
I would try and stabilize on the single rank 3000 kit and have the 3200 kit downclocked. You aren't going to be able to use the XMP selection in the BIOS because I assume it will detect the 3200 kit only which is going to be very wrong for the 3000 kit. Best chance is to set the timings manually and very loose.

Start with what the DRAM Calculator cranks out for the 3000 kit but choose the dual rank configuration and 8 sticks.

Without a Thaiphoon Burner report I don't know exactly what memory dies those sticks use, but I suspect they are Micron E-dies. Try plugging that into the Calculator for the 3000Mhz setting.

Details of the driver at lkml.org.

Good point. And I do wonder if there will be additional downward price pressure on the 3900x after the 3900xt is shipped?

In the short term, simply reducing the # of cpu threads running tasks will free up enough cpu threads to drive a 3rd Radeon 5700.
