Question Odd ms/inter and ETA info on one machine

Hello, I am fairly new, one of my machines is doing this:

Quote:
[Sep 24 23:15] Running Jacobi error check. Passed. Time: 72.364 sec.
[Sep 24 23:16] Resuming primality test of M86542459 using FFT length 4608K, Pass1=1K, Pass2=4608, clm=4, 4 threads
[Sep 24 23:16] Iteration: 84042885 / 86542459 [97.11%].
[Sep 24 23:19] Iteration: 84050000 / 86542459 [97.11%], ms/iter: -1.#QO, ETA: -2147483648:-2147483648:-2147483648
[Sep 24 23:22] Iteration: 84060000 / 86542459 [97.13%], ms/iter: -1.#QO, ETA: -2147483648:-2147483648:-2147483648
Instead of this, on a "normal machine":

[Sep 24 23:50] Iteration: 16530000 / 86725739 [19.06%], ms/iter: 36.152, ETA: 29d 08:55

It is my only machine with this processor:

[Main thread Sep 24 23:14] Mersenne number primality test program version 29.4
[Main thread Sep 24 23:14] Optimizing for CPU architecture: AMD Bulldozer, L2 cache size: 2 MB, L3 cache size: 8 MB

Quote:
Software Version: Windows64,Prime95,v29.4,build 8
Model: AMD FX(tm)-8350 Eight-Core Processor
Features: 4 core, hyperthreaded, Prefetch,SSE,SSE2,SSE4,AVX,FMA,
Speed: 4.113 GHz (8.382 GHz P4 effective equivalent)
L1/L2 Cache: 16 / 2048 KB
Computer Memory: 16284 MB configured usage 1024 MB day / 512 MB night

The CPU page does display an expected time: 2018-09-26 00:01


Not sure if this is a setting I need to tweak or if I can ignore it. Would be nice to see what it's doing performance wise in real time though!
