    There's nothing to not like about the 8350. Power consumption is around 10% less compared to the 1100t (3.3Ghz) and to top it off, it has two extra cores. Compared to my X6 @ 3.9Ghz, WUs take slightly longer on the 8350 to complete (about 15-20 min more) but since you're doing 8 at a time the FX has the upper hand.

    The downside is that, based on some reviews I've seen, power consumption grows exponentially with overclocking. A 10% OC would increase power consumption by 20%, at 5Ghz (25% OC) you'd be looking at a 70% increase (see FX-9590). Running them stock is the sensible approach if you plan on crunching 24/7.

    It seems I've been hitting my thanks button too much since the forums seems to have taken it away from me. I really appreciate the insight though (despite my lack of thanks-button-pushing).

    I've heard of the FX's quickly increasing power consumption when overclocking. I'm mostly concerned about managing the heat though since my house isn't air conditioned, although it shouldn't be too long before it's under water. The next question is if it's worth $200. I guess I wouldn't be losing the X6, but it would likely go to my father who doesn't like distributed computing.

    Comparing Norton's 8350 + overclock to mine. (Hope you don't mind me nabbing your statistics, Norton.)

    Explanation:
    Comb. MHz: Cores * Clock speed
    avg/mhz: Clock for clock, which one's faster overall.
    avg/mhz/core: Clock for clock, which has better single-threaded performance.


    I'm kind of comparing this to an eBay Phenom II X6 which, I believe, is somewhere around $100 - $150.

    From my experience: with the FX, the power consumption is like an ocean floor - first it gets deeper slowly, then when Ya reach the end of the shelf - BAM! It suddenly gets insanely deep.
    In my FX-8320, the breaking point is 4.1 GHZ. Going past that requires voltages which seem to start producing A LOT of leakage, and thus, power consumption starts skyrocketing.

    Well, that's not bad at all. My 2600k on WC is at ~60C, but admittedly is OCed as well. Would the FX8 CPUs not handle the heat?
    You're having the worst of luck :(
    If you end up needing a new power supply, I can look and see what I have. I know that I have a 350w, as useless as that would be, but may have a 550/650 as well.
    I tend to just turn off power saving features on my crunchers. I don't remember if I did on the Mint system, but I've had no crashes on it...
    AMD specific perhaps?
    Check out my PPD estimator? ;)
    From what I've seen, the ~4.2-4.5GHz is really easy to get. 4.5-5 requires much more in the way of cooling, but also doable. The AMD FX8s are pretty sweet for WCG from what I've seen (albeit the power usage isn't as good as the i7s)
    Glad to hear that you're safe! :toast:

    Hi! I'm from the Internet
    To me I see an increase in ppd with the FX compared to the PhII's. Especially when they are both at stock clocks. The Fx will wipe the floor with the x6's. It's a 2k+ ppd difference. The only PhII rig I have that can come close is my overclocked 1090t. With the fx at stock speeds they trade blows with the Fx taking the lead most days by about 500 ppd or so. Now if I ramp up the fx then it would take down the 1090t easily. Whether it's worth it is up to you. I feel I made a great purchase. And I am thinking of replacing my 2x 1055t and 970BE rig with Fx's.

    That seems to be the consensus with the FX-8350. I haven't seen anyone complain about the chips stock performance and most would buy another one.... I know cuz I did! :D

    @xvi- Don't follow the ppd vs clock on the 8350 in my main rig too closely. The clock speed has been changed a few times since installed.

    FYI- It's been at 4.2Ghz and under 1.3v for the last month or so- It ran 4.4Ghz initially and runs 100% fine at that speed but I turned it down for the Summer to keep the heat from 3 rigs running at home under control.

    Yeah, you guys are making me want one now :p
    I just wish that there was a way to stick two of them together--I'd like to have more output from fewer systems...

    Actually, I was thinking of doing such a thing. In case I manage to snatch a dual-socket [server] mobo for a reasonable price :laugh:
    But decided to wait for steamroller to go on with such a thing.

    Yup, it went on intermittent yesterday or the day before. We're down to just two projects now, and I don't like that :(

    I don't it either. As a team do we have a plan for if work runs out even for a short while?

    I'm thinking/hoping WCG will roll out a fresh project or at least some beta projects before too long.... hopefully within the next month or so.

    If not, we will need to look at some of the other projects and see if there is something that all/most of us are willing to move our resources to.

    Maybe we should consider starting a "what if" new project discussion thread

    I would be astonished if we don't get another project soon. If we don't, and WCG does eventually run out of work, then I'll transition my resources to our Folding@home team.

    Seriously I think your right Norton. We should probably at least start a discussion on what the team could do.
