    My electricity bills are kinda silly each month at the moment too, i'm not sure how much crunching will affect them. so I'm crunching 24/7 on my laptop, which gets almost the same ppd as my desktop, then i set up 2x dual-cores (2.8ghz) at work to crunch. Hopefully that should keep my PPD up. I think i'm averaging close to 2.5k PPD now. I've been looking to undervolt my video-card to save on power while it idles, but i'm not sure how much energy going from 1.2v down to 1.0v would save on a 4850.

    Laptops are typically very efficient in terms of PPD/W

    OK team, I have some bad news and some good news. The bad news is that most of the systems running WCG at school seem to have been turned off for the weekend. If I remote into my school-hosted laptop, I can ping a few of them, but pings to most of the computers time out. So my PPD will be down to a couple PentDCs, my W500, and my i7 part-time (see below) until Tuesday AM.

    The good news is that I've been given permission to crunch part-time again on my i7 (I'd guess probably 8-12 hours a day most days).

    I've also dispatched an email to James, and if he replies in the affirmative (that he can get me a list of all of the usernames at school) I'm halfway to getting the Mac Minis going.

    Good luck Ion.

    Hopefully one day you'll have a real farm once life goes your way eh? I wish I could output that much. Dang car and needing repairs....

    Thanks. Even if the Macs only run when not in use, that's another ~5-6k PPD easy. More like 7 or 8k if they run 24/7

    Oh yes. Definitely. I'd love to have a half-dozen of whatever the upper-mainstream systems of the day are :p

    I should hopefully be taking the X2 offline for a X4 soon enough. Then maybe making the X2 into a HTPC/Cruncher

    Very cool indeed. Will this be an upgrade for Lauren's system?

    Indeed. Only reason I haven't done it yet was because I'm about to change jobs/fixing my car.

    That makes sense, I haven't done it because I don't have the money to pay for it or any ability to power it :p

    I haven't had a computation error in a while...I wonder if it's the undervolting or the hate between HPF2 and Windows x64

    Can't remember which one but one of my rigs can't run that project, errors each one. ..and trust me, it's not stability problems.

    It's weird, because it's done HPF2 fine until now. I'll see how it goes, and pull it off HPF2 if needed.
    Excellent!

    So WCG on the Macs almost certainly isn't happening. James was afraid that giving me a list of every single username could pose a security risk (why I don't know, but that's what he said) and he was afraid that WCG could do bad things to the Macs in terms of temperatures (he figures they aren't exactly designed for extended load). So that's a shame, but I'm going to see what else I can find to get crunching

    Keep us posted ion.


    Gary, thanks for taking your time to fix the problem and putting it back to crunch bro. :rockout:

    Finally got some time today to play with the i7 2600K. Think I found a sweetspot:

    Column 1 Column 2
    0 i7 920 i7 2600K
    1 3.8GHz 4.6GHz
    2 ~230 Watt ~160 Watt
    3 82C Load 72C Load


    It seems you quickly loose the half power consumption estimates as soon as you overclock. But 10C and 70W less for Sandybridge seems very nice for multiple cruncher setups. If the sell value of your current crunchers make the upgrade affordable I'd highly recommend it, as you'd probably get that money back through electricity bill savings.

    Oh, yes.. that means this is +1 cruncher :rockout:

    ^ I wonder if its as big a difference when compared to Lynnfield setups. I need to grab a Kill-a-Watt already- if only I didnt miss them whenever they go on sale :laugh:

    Yeah those things are definitely quite useful. I bought mine ages ago and after seeing everything round the house I chucked it away and forgot about it :laugh: But yeah now anything I plug in needs to be tested. Too easy for costs to spiral out of control otherwise.

    Expect more points from me, coming soon. I just pushed my E2160 further, from 2.4GHz to 3GHz. The power supply that was in there was holding it back... the new one is taking it to places it couldn't reach before.

    So basically your SB chip is 800mhz higher clocked than my Lynnfield and draws 90w less.

    What GPU is this with?

    That's simply astonishing....wow. All I can say.
    I don't have a lot of results for my i7 860, but I measured it at ~250w with the CPU @ 100% and an idle GTX260 @ 3.8ghz
    At stock clocks (2.93 b/c of turbo) I think it was ~180 or 190w load w/ the GTX260 idle
    Cheers :toast:

    Running it with a cheapo 8400GS for low power and no noise and a Gold certified PSU to try squeeze the efficicency. Need to look at the Flash on Sata thing mentioned on another thread, I've got a "reduce electricity waste" kind of mood.

    Ahh, so I guess our comparisons aren't strictly speaking accurate. I had my "green" GTX260 & an 80+ bronze PSU

    My X6 and X2 were offline most of the day today, X2 had Ethernet cable come off, that's back on now. The X6 was off, kept locking up. Just left it off and now it's fine. We'll monitor it closely.

    I saw that you had no points for FAH the past few updates--glad to hear it's resolved :toast:

    I just swapped out PSU's on my main rig. I believe something came loose on the old PSU as I was hearing a horrendous sound last night when trying to sleep. When the PSU's were swapped, I happened upon a small screw with no idea where it happened to drop from, my main guess being my old PSU (although how it happened, I still haven't figured it out).

    My main rig is now up and running again, this time with a 600W Corsair PSU. That damn screw woke me up from a deep slumber, and I'm one of those people where a tornado can crash through the house and I'd ask what happened the next morning. Hopefully I can try and salvage the old PSU as it still supplied juice to my rig.
