    And I glad that finally gone from Nvidia's chipset. Despite the fact that glued more fans, it was easy and quick to boil the kettle.

    My 8150 is running at about 52-55c on a Hyper 212 EVO at 1.36v in CPU-Z. I might try 4.2GHz and see if the droop decreases so I can set a lower voltage and get lower temperatures as well.

    Once that 8150 starts running up the ppd you may just end putting some better cooling on it and making a few adjustments :D

    *note- I'm running the FX-6200 at DDR3-1333 and it's putting out great ppd so memory speed may not be all that critical for the FX chips to crunch well.

    That's another thing I wanted to ask, actually. I have a pair of G.Skill 2133 CL11s from my main PC, running at 1866 CL10 at the moment on the FX. Does FX like higher clocks or is 1866 the sweet spot as with Sandy Bridge?

    I noticed that FX can't really handle high NB or HTT clocks as well, which I assume is probably why every chip is fully unlocked. Craps out at ~230 HTT and I believe the NB only goes up to around 2500 or so. And yes, I did give it a little more CPU/NB voltage to give it a bit more stability.

    Went through a lot of that this year while Comcast sorted some things out in my area. Luckily it's been doing really good lately.

    I have not noticed the difference between 2133 10 -11-10 and 1866 8-9-8 in synthetic benchmarks, and therefore left 2000 by XMP profile. In addition, the memory speed will not give you any gain in WCG, Norton is absolutely right. Maybe, FX has enough cache to operate on the data? Don't know.
    As for the high HT and NB, it is no advantage in speed, just more heat. 2400 - 2500 is the optimal frequency, which allows to work with any frequency memory. This is a important difference from the Phenom.

    EDIT:
    Here are some results

    @Daimus- Thanks for the info you provided on the FX :toast:

    You have way more experience with these FX chips than I do! There are a couple of things that I have seen using them:

    - Memory speed, as you confirmed, doesn't really affect WCG ppd. I may try tightening the latency on my systems to Cas 7 or 8 to see if I get any benefits there.

    - These chips work best when loaded/performing work on all cores and still have plenty of room left to do other things, the multitasking is incredible!!! When I try to do other things with the Phenoms while crunching the performance is sluggish... not so with the FX. When I'm online at night I'm usually doing, or can do, all of the following on my main rig:
    - Crunching (100%/100%... sometimes 100%/95%)
    - Watching TV on the tuner card
    - Web browsing (multiple windows open)
    - Editing screenshots/looking at photos
    - Playing a PC game
    Temps never change when doing all of this stuff either :)

    It's really so. FX is the first CPU that can at the same time:
    - 100%/100% crunching
    - operate on database
    - web serfing
    - MS Office
    that is what I do every day and without delay. Unfortunately, this is not so good with games...:shadedshu But I almost did not play.

    Yeah, I've noticed my FX machine is surprisingly usable while crunching. Folding however really bogs down your GPU except for the 6950 I had, which still had about half of its graphical performance left while folding. Thanks for the FX clock chart, by the way. :)

    I play BF3 while Crunching with my Amd 1100T. I have not noticed a hit to either

    What do you set the percentages at to do that?

    Any of you know a good cooler for a A6-3500 on a Gigabyte GA-A75M-S2V with both memory slots in use inside a Thermaltake V3 Black Edition?

    +1 for the Xigmatek Loki. It may be a complex bolt-thru cooler but my X3 720BE under full load at 3.4GHz/1.35v is reading 33c on it.

    I've run the other two- the AC Freezer is the easiest/quietest (2 screws and done for AMD setups :toast:) and the Xig. Gaia with the 120mm fan does a bit better than the Loki as far as performance (same mounting system as the Loki).

    lol, I still have a Freezer64 Pro in my parts drawer. Was no match for a Phenom 9750 though (the last time I used it).

    You think I can figure out how to attach a bolt-thru cooler?

    They give you a leaflet that explains it pretty well. Just don't tighten the bottom nuts that secure the bolts and bracket to the board too tight, or the board will severely warp due to the thick foam pad on the backplate.

    You think it ships with cooling paste, or should I order some on the side?

    Also, AC Freezer is about 30$ and Xig. Gaia is about 40$. Any further thoughts then?

    My Loki came with a one time use packet of generic white paste. You may want to buy a cheap tube.

    The Gaia may be too tall for some cases like the Hyper 212 coolers.

    For an AMD APU and limited experience in changing coolers, the AC Freezer 7 will be a good fit for you:
    - very easy to install
    - cools much better and is quieter than stock
    - cheaper

    As far as paste... the AC comes w/paste preinstalled on the cooler but it is good practice to always have some cooling paste on hand. I use Artic Silver 5 and never had issues with it but there's many more brands out there.

    ** EDIT @jr- have you seen the shipping rates from geeks.com lately!!! can buy new for only a few $$ more? **

    Actually it isn't horrid. But I guess you are right. Could drop the MX-2 and use stock TIM and buy the Yate Loon somewhere else.
