You can compare your wcg opng results with your wingman: under your account, click Results Status, then click on the name of the workunit in the Result name column. You will see your wingman here. Click on the Valid link in the Status column.

Tom, if you want to have an idea how a gtx1660 (non ti and non super) performs, check my host: ID: 8838390
This PC uses the special sauce. The CPU is mostly crunching WCG, occasionally SETI. The GPU only crunches SETI 7/24, RAC is around 50k. The GPU alone consumes 90 Watts while crunching SETI. It is pretty efficient.

thanks for the suggestions to everyone.
Its still a mystery why the nvidia module has disappeared after a simple a reboot, but now, as Keith suggested, I reverted back to nouveau driver and the machine is crunching again. Also there are some AP tasks completed and validated by this host.

To be honest, I don't want to mess anything with this host, because it is working as intended, although it is still using the nouveau driver. Is there any advantage to use ppa nvidia drivers?

Thanks.

After this operation, 395 MB disk space will be freed.

so if i understand this correctly, the driver is installed.
I used the ppa method to install nvidia driver. Tried 390, 410, 440. Nothing works.

Did someone face similar issues?

The TDP of a 3700X is 65watts. The TDP of a 2700X is 105watts. So I expect the 3700X to be more power efficient at the same clocks.


TY. I still yearn for "more cores" but if I continue to be on the hunt to lower my power bill without lowering my crunching this looks like a possibility.

Last month I paid $485 for my power bill. This month it looks like may $200.


I think these TDP values are true, when core performance boost is disabled. When core performance boost (not PBO or AutoOC!) is enabled, core package power rises significantly: my 3900x eats 145W with core performance boost enabled (without PBO and AutoOC). The TDP is 105W according to AMD.
(if you do manual overclock without undervolting, power consumption will rise further)
With -0.064V undervolt max core package power decreased to ~130W under World Community Grid. Noctua NH-d15s can keep this beast around 75-77 Celsius under 75% WCG load, which is fine I think.

If you disable core performance boost, your CPU will operate only on its base clock and won't boost. You will loose performance, but its package power consumption will be close to the advertised TDP value.

I have a Vega56 and it turned out that my overclocked Ryzen 1800x CPU is more efficient under Seti than my Vega56 undervolted and using optimized ATI app (and command line parameters) under Windows. If you don't care about efficiency (I mean performance/watts) than give it a try, it can do about 20k RAC I guess. But with constant 180-200W power consumption. Not a good deal.

Keith,

What temperatures are you measuring using the AVX app on your 3900x? What cooler do you use on that beast? How many CPU tasks are you running in parallel?

I am planning to swap my 1800x to a 3900x but I see temperatures are problematic...

Right now I am at 80° C on the cpu in a 27 °C. room. I am running 12 cpu tasks and 3 gpu tasks concurrently. Have a manual all-core OC multiplier of 43. Using 1.25V on Vcore. Only using a EVGA 280 CLC cooler. I also have two 2080 Hybrid gpus dumping their heat into the case which does not help the cpu temps. If I wanted to drop the temps dramatically I would go for a bigger case like the Thermaltake Core X5 that I have the Threadripper 2920X in. I have dual 360mm X 60mm radiators in it. One loop for the cpu and another loop for gpus.


Isn't 80° C too much for this chip? I don't like seeing my 1800x above 70° C... I know 7nm ryzens begin to throttle at around 90° C , but I don't know if it will shorten the life of the CPU if being continuously used around 80° C.

I used both Mike's and Rueike's command line parameters on my undervolted Vega56. Not much difference, just few seconds. OS: windows 10.
Based on my findings, a Ryzen 1800x @3.9GHz (1.25V) is much more efficient than my Vega 56: roughly the same RAC with lower power consumption (blc33):
- Vega56: ~19k RAC/day, ~150W power consumption
- Ryzen 1800x: ~19k RAC/day , ~105W power consumption

this is under windows 10 with the latest Lunatics Apps installed. This is why I won't use this Vega for Seti any more.
Maybe I will find another project for Vega where it may be more efficient.

try 1.35V cpu core fixed and 4.0 GHz on all cores manually. Should be fine, but needs to be tested. If its stable, lower the cpu voltage.

one more comment on the RAM:
Based on your MB's QVL here: https://www.msi.com/Motherboard/support/X399-GAMING-PRO-CARBON-AC#support-mem-17
you can see anything above 3000MHz needs 1.35V.

I started with DDR4-2666 CL 16-16-16-36 1.2 volts. (4X4GB) Upgraded the ram to DDR-3200 CL 16-18-18-18-38 1.2 volts. (4X8GB) Upon further discussion by Keith it appears I made a mistake in identifying what I needed to upgrade to. I needed to upgrade to a CL 14 kit

as far as I read on different forums, for ddr 3200MHz, 1.35V is recommended on Ryzen systems. Not sure about threadripper, but I think that 1.2V is simply not enough.

On the other hand, you are modifying too much parameters at once. Put your CPU back to its factory default settings and test RAM stability first. Use memtest86. If that's stable, move forward with the CPU.
BUT, keep in mind that your CPU is YERY power hungry. I am not sure if your motherboard can handle that amount of power if you overclock. Just run it on default settings for a few days. After that, increase 100MHz, then test for a few days.

I wouldn't try that 4.0GHz all core overclock. your motherboard's VRM can be a weak point.

Now completion times stabilize around 220 seconds for blc01 tasks.
If I get ~50 credits for a single task, then it is roughly 800 credits/hour using 140W/h power on average.
Not as bad as I thought.
I didn't expect such throughput/efficiency based on the diagram that Shaggie76 posted on the previous page.
Thanks Mike and Tom for the tips.
