    If I upgrade my CPU can I keep the downloaded workunits?
    Everything else in the box is the same, I'm just upgrading the CPU.
    Existing:
    i3-4130 (Gen 4)
    New:
    i7-4790K (Gen 4)
    I've tried to let the workunits run out gracefully but everything arrived from eBay much quicker than anticipated and I've still got about 5 days worth of workunits to process... I don't want to abort any tasks if I can possibly avoid it. May I keep them while I upgrade the CPU?
    Thanks.

      If you have enough space

        If you have enough space available I would backup your boinc data folder. It's normally hidden in windows.

        That way you will diaster proof yourself.

        Like Ian&SteveC says there should be no issues that are directly related to BOINC.

        If your CPU exceeds your CPU cooler it could be a problem.

          3 tasks were running on the i3-4130.
          And all re-started with the new i7-4790K fitted -

          Elapsed~
03:27:00    Gamma-ray pulsar binary search #1 on GPUs 1.22 (FGRPopencl1K-nvidia)
10:14:00    Multi-Directional Gravitational Wave search on O3 (CPU) 1.02 (GW-SSE2)
03:06:00    Gamma-ray pulsar binary search #1 on GPUs 1.22 (FGRPopencl-intel_gpu)

          I suppose it remains to be seen if they validate...

          A point of note is that the i7-4790K CPU running flat out (but not Turbo), including the IGPU, oscillates over ~10s between 80-90 °C with the old i3 stock heat sink and fan. I guess that'll change on a hot day though. It draws about 77-88 W. The old i3-4130 was steady at around 55 °C and drew around 40 W.

          When I'm not gaming or surfing I give the PC over to BOINC at about a 40/60 split during a 24hr period. The i3 , including the iGPU and nVidia GTX 650 turned over about 28,000 (Einstein) a day. We'll see about that... ;-)

          It's odd that when I first booted with the i7, leaving both the Turbo and Hyperthreading off in BIOS (careful now), it ran hotter than with Hyperthreading later on. And the i7-4790K seems to use less RAM than the i3-4130 under general use. Weird. But nice. It might be the enormous 8MB L3 cache...

          Thanks for the encouragement. Needed it.
