Interesting you're seeing 4.1, I'm only seeing 3.3. Maybe the extra memory bandwidth is giving the CPU more work to do, hitting the power limit easier?
6.6 at 1 hour 30 minutes. 4.1 ghz (linux, lscpu is all I have)
Edit: my memory is slower, but its not locking up, so I will let it run !
What cooler are you using ? the temps could be slowing you.Interesting you're seeing 4.1, I'm only seeing 3.3. Maybe the extra memory bandwidth is giving the CPU more work to do, hitting the power limit easier?

Are you running windows or linux ?Quite the opposite. It's the Optimus Foundation AM4 block on an overbuilt loop (built for also having the 6900XT but there isn't a block for it yet).
My temps are around 50C
psensor only shows me GPU temps, and cpu usage, no temps. over 11% done in 2:32Mark what are your temps like while running Primegrid? Psensor is a good utility for checking temps in Linux unless you already have another way of checking. The FMA3 work with Primegrid hits the CPU pretty hard, and before I turned on eco mode on I was seeing pretty high temps on a 3900x or 3950x even with a pretty good Noctua air cooler. I would think a 5950x would be similar.
Where the heck did you get a dark hero? I gave up and got a hero viii WiFi for my 5950.For sure, it looks like we started this batch of work around the same time - as of 3:47 PST I am 23 minutes elapsed and 2.040%/2.020% complete.
I'm on an Asus Dark Hero X570. I've got a kit of 2x16GB dual rank b-die 4000CL16 G.Skill Trident-Z RGB. I applied the timings from Ryzen Clock Tuner for 3800 fast b-die and then tweaked CL, secondary, and subtimings from there. It's taking 1.5Vmem so I got a memory cooler. The cooler keeps the memory at 35C at the sensors. Memtest will throw errors without it and the memory will heat up to 50C at the sensors.
Before this I was running 3800CL16 from the Ryzen Clock Tuner profile with no tweaking at 1.35 vmem and no cooler stable.

I may have to try out prime grid if it’s that much of a stress test. How long is the current competition running?

That is, you made sure that each task is running on its own dedicated CCD, did you? Spreading a task across CCDs would most certainly slow things down.I got that all setup, 2x8 thread tasks and I set the affinity of each task's threads to the 8 physical cores on each CCD.

(On my dual socket computers, BDW-EP and Rome, I don't tweak affinity but simply rely on the Linux kernel's process scheduler to do the right thing.)
SoB definitely seems to perform different than most projects(probably because of the cache requirements?). Haswell Xeons perform better than I would have expected. It's nice to see them still perform well compared with newer hardware.It's funny to me that my 8700K, formerly one of my fastest CPUs but now relegated to the HTPC, is so slow at SoB that I am not allowing it to continue after this next task completes.
They will finish in 23 hours and 15 minutes,

Meanwhile, the search space progressed enough that there are some tasks with 3,456 K FFT length out now, that is, with 27 MB cache footprint: Post. (Michael Goetz didn't specify if that's for all implementations, or AVX-512, or FMA3, or...)I looked up the current search range of Seventeen or Bust and checked its FFT sizes on a Haswell CPU. Haswell and all later Intel CPUs which don't implement AVX-512, and several AMD CPU architectures including Zen 2 and certainly Zen 3, will use the same FFT implementation here, which is "all-complex FMA3 FFT".

It looks like memory speed impacts performance a LOT. 3200 vs 3800 takes 25% off the time.Mine is looking to be done at around 17.5 hours. I left the CPU on the stock config for our comparison but its going back into high gear for the next one.

And I think your $420 motherboard is what allows that vs my $220 motherboard.
I spent about 2 days worth of work tightening the timings and adjusting the voltages for my 5950 on my Crosshair hero viii (wifi). The default settings w/ XMP enabled used way, way too much voltage on the memory controller, which was unstable at higher clockspeed. Dropping the SOC voltages allowed me to get to 3866 stable, and 4000 mostly stable. My guess is that 4000 would be stable if I had less than 64GB ram, but I don't have extra ram (or the patience) to buy a smaller kit to see if it changes the stability at higher clocks.It looks like memory speed impacts performance a LOT. 3200 vs 3800 takes 25% off the time.
