So I just use stock settings, always have. I don't use PBO.
I'm not getting any issues so I guess my settings are working. It does get a bit warm though. At 4Ghz the general temp running 8 consecutive tasks in around 84 degrees C. It has spiked to 100 degrees C though..... but it was just a spike. It is heading towards summer here in Australia. This is with a H100i Pro.

Good to see I'm not on that list.
My 3950X runs at stock. I don't use the boost settings in the BIOS. I figured running BOINC 24/7 at stock was harsh enough :)
Running 8 tasks is currently clocking at 4.0Ghz.

First prime!

Congrats to whoever the lucky owner of that prime is.
How do we see who the user was?

Timings for 400K all-complex FFT length (16 cores, 8 workers): 0.85, 0.77, 0.75, 0.76, 0.76, 0.79, 0.77, 0.75 ms. Throughput: 10319.82 iter/sec.

I think I like the look of that.

Thank you very much for taking the time to reply guys. I do appreciate it.

Raf -
I haven't had that much experience driving Prime 95. If I've done it right, a quick test on my 3950 came up with this -

Timings for 400K FFT length (16 cores, 1 worker): 0.42 ms. Throughput: 2367.28 iter/sec.
Timings for 400K FFT length (16 cores, 4 workers): 0.39, 0.38, 0.38, 0.38 ms. Throughput: 10525.06 iter/sec.
Timings for 400K FFT length (16 cores, 16 workers): 1.39, 1.40, 1.38, 1.41, 1.41, 1.41, 1.40, 1.39, 1.42, 1.41, 1.45, 1.44, 1.40, 1.39, 1.37, 1.44 ms. Throughput: 11374.65 iter/sec.


So 1 task for each of the 16 cores is slightly better than 4*4.... is that correct?

Edit - I see you selected "complex FFT" so ran it again -

Timings for 400K all-complex FFT length (16 cores, 1 worker): 0.67 ms. Throughput: 1498.00 iter/sec.
Timings for 400K all-complex FFT length (16 cores, 4 workers): 0.41, 0.40, 0.41, 0.38 ms. Throughput: 9920.27 iter/sec.
Timings for 400K all-complex FFT length (16 cores, 16 workers): 1.50, 1.50, 1.50, 1.49, 1.46, 1.47, 1.46, 1.48, 1.47, 1.48, 1.51, 1.47, 1.46, 1.47, 1.47, 1.46 ms. Throughput: 10832.87 iter/sec.

Similar result :)
