The question is not how long it takes to compute a WU but furthermore how many credits you finally earn.
Depending of the project, and sometime of the project phase as well, the duration of Work Unit could vary significantly.
Additionally, I did sometimes observe that the starting credits are not always representative until the machine works reliably for a couple of weeks, in particular with not widely spread configuration.
I assume that there is not a lot of TR 2990WX operating on WCG. For this reason, a longer test of the TR monster would be probably more representative.

I'm using on of these on my T/R 1950X and recently bought another fan so it's in push/pull config but my CPU is throttled due to temperature issues. Even with an ambient room temp of 29 degrees Celsius, I cannot cool this beast.
I might give the case a clean out and reapply thermal paste but overall I'm disappointed that it's a struggle to run all (or most cores) without being throttled.
No doubt a fair bit of heat is coming up from my 2 x Vega 56's. I have 2 x 120mm front, 1 x 120 back and 1 x 200mm top fan.

(slightly off topic but currently running Primegrid at 50% CPU usage just to maintain 3.2hz :( A drop to 25% CPU usage gets my speed almost back to stock.

I'd seen your stats VietOz as I spend a lot of time trolling stats. Very impressive rigs you have! You're like my Gold Lotto dream LOL.

Oh..btw which thermal paste application method did you use?
I've seen a video on Gamers Nexus where the "big blob" worked best lol.
I originally went with the std AMD application method of 5 dots.

Oh, that's interesting you have a ASROCK Taichi also. I have a question for you. If you sudden lose power to your PC, does it fail to reboot? Or takes forever to reboot?

I often have to do a system restore or wait HOURS for it to find Windows 10 again. It's done this since day one. I can only put it down to the mobo.

The Windows logo just spins round and round. Just last week I swapped a GPU between slots and had the same issue. It's quite frustrating. I was always curious if other had the same issue.
I also stopped using the built in wifi. That well known issue of having to reinstall the wifi driver all the time drove me up the wall. Every time my PC crashed I'd have to reinstall the Intel wifi driver :( All hardwired now with Cat 6 so no issue anymore.

I'm using the same cooler on a TR 2950x, and I have no temperature throttling. With 32 threads of WCG I'm at 60°C max (Tdie according to HWiNFO64) with 1000rpm on the single included fan. Your room ambient is eight degrees higher than mine, but the fan goes up 1500rpm, so my system should be comfortably (a couple of degrees) below the 68­°C limit even at your ambient temps.

If you're struggling with temps, I suggest you first try taking off the side panel. If temps improve or throttling is reduced, the issue is airflow through the case, and you can focus on improving that.

I don't have temperature issues, but I still have throttling: The CPU runs at 3.8 GHz while it should be able to boost up to around 4.1 GHz on all cores.

But I think that's from the power limit (or possibly the current limit), at 3.8 GHz the "package power" (power for the entire CPU) is 179W while the TDP is 180W. I haven't started experimenting with the Ryzen Master PBO yet, but that's where I'll go to increase the limits.

I'm using Windows 10 64 bit version.
