    -smp 7 leaves a core for the gpu3 client it needs 5% to 7% of cpu time on mine. i got 5k ppd more than with -smp 8. i no longer do bigadv as to close to bonus cut off. i run my 17 875k@3900 with voltages of cpu 1.275 and imc 1.225

    Coretemp displays CPU VIDs on older chips but I don't think it will on yours, it doesn't on my i5. The thing I do is check the core voltage under load in CPU-Z and use that value. My i5 was 1.2v if I remember correctly, it needs 1.328v for 4Ghz.

    What sort of ppd do you get now, doing normal a3 WU?

    Ok, after 15 hours of folding temps stabilised on 58 degrees on full load.

    As a complete noob:

    1. Is the next logical step the proper watercooling?
    2. Would I see any decrease of temps with a proper loop (in simple words, is the cost of the loop justifiable?).
    3. Is it as hard as I fear or is it reasonably straightforward?
    4. Is it possible to start with the loop just for the CPU and when I get comfortable, can I expand it to the GPU and motherboard?
    5. Does Fractal Design R3 case can take 240mm radiator on the top?

    Thanks guys for great help so far. And I appreciate time taken to help me.

    Just to reply to phoenics question, fan set-up is: 2 front intake fans, one side exhaust (for the GPU) and one top exhaust (for the CPU), Corsair H70 in push/pull set-up pulling air from the outside.

    Thanks guys.

    between 11k to 14k on a3 wu. between 8k to 15k on gpu3.

    I now believe it's the motherboard that's not right.

    1. Tried -bigadv flag, PPD dropped to 2200 and ETA was more than 4 days. That's beyond the deadline, but on the processor like that? H55 chipset though supporting i7 doesn't seem to take the full advantage of it.
    2. Seems memory slots are dying. Needed to move one stick to the 3rd slot as first two aren't working anymore, as a result I'm running in single channel mode.

    Can't wait for the new mobo! :wallbash:
