    Hi! I'm from the Internet
    I never did a stress test on mine. I just cranked it to 4.4 and let it rock. Haven't had any issues. I don't know much about the board you are using as I refuse to use anything newer that has Asus name on it. I am running mine in a Gigabyte 990FXA-UD3 rev 1.1.

    I considered that one too, but given my success with the Maximus IV, P9X79, and P8P67 I ended up going with the Asus. I'll see if I can get it working any better.

    +1 Just crunch on it and watch for errors... no need to stress test. Crunching IS the stress test :pimp:

    I feel much better even running just an hour or two of Prime95 or LinX--but I'm not going to waste a couple days just heating the room to test an OC when it could be crunching ;)

    Prime95 is junk anyway and I've had times where LINPACK stress tests worked fine yet the system would still crash on something simple. Crunching is IMO the best stress test.

    Take in mind, Linpack uses some extensions that boinc might not use at all. My 1090t crashed on Linpack at anything north of 3.8Ghz but it has happily crunched at 3.93Ghz for months without issue.

    Kind of how my QX6800 runs at 3.24 "Cinebench stable" but IBT kills it in the second loop. Never had a crash on any other program apart from IBT, not even boinc in the short time I crunched on it.

    I was just offering the bracket if you wanted one :) I know I have that type of Dell Radeon X1300(?) around.

    I got the same cpu.

    Had it OCed with no problems for a while and run WCG WUs.

    Then I figured out how to have more than one Clean Energy Project working and got some random BSODs...

    Set the cpu back to stock and no major problems since.

    Mind you, might also have something to do with the memory, as though WUs are also memory intensive, no?

    I've never seen memory usage go above 800MB in my linux crunchers. The CCTV PC (Win7) has 2GB of RAM with 256MB used by the IGP and it uses 1.2GB.

    If anything, WGC is somewhat I/O intensive (lots of small saves for checkpoints).

    Hi! I'm from the Internet
    I whole heartily believe this. I have found that if my rigs can crunch without issues for a few days at there clock speeds and also without erroring out wu's then they will run whatever I throw at them. Hell I have gamed on my Fx rig while crunching (forgot to shut wcg down). It doesn't seem to effect it at all. :toast:

    I just don't want WUs to error or send back ones that will be marked as invalid--my big reason for something else first ;)
    Well, I'll give OCing a shot again later this week. I suspect that I won't have the time test out anything until Thursday or Friday, but we'll see :toast:
    I don't know if it's a Dell card, but Mint does identify it as a "Radeon X1300/X1550".

    Indeed, it does quite look like that. I've had an X1300 before, and they're awful cards for actually doing anything with, but for what this needs to do, it works just fine :toast:

    Now I have to resist the urge to go and buy another FX8 :p

    Indeed--given that I could put together another FX8350 setup for less than $400, it is very tempting indeed :D

    Perhaps in a month or two, then I can :)

    A friend and I refere to these as "heaters" because they often do little else but add heat to the Dells they came from.

    Awesome project, [Ion]!
    (how come I didn't notice this thread before?)

    I too dislike ASUS [dontask] and get Gigabyte mobos when I can, but with the FX CPUs, there's a bit of a problem. AMD's specification requires the BIOS to gradually downvoltage the CPU when it's load & power usage increases which can drop the voltage by as much as 0.17V (the most I've managed to see before crashing). This spec is kinda obscure and "stealty" (unexposed), so I even had this embarrassing thing because of it (that thread is highly misleading and contains info that turned out to be BS later, though). I haven't seen any mobo 'cept my current "main" mobo (ASUS Crosshair V Formula-Z) to allow to control this "feature". This mobo exposes a deeply buried setting which allows to go around this spec. Which means when I got this mobo I was FINALLY able fine-tune my voltage & retain explicit control of it... *sigh*

    For stress testing, I usually run the Linux version of Prime95. I first run its stress test on all cores for several to see if the "normal" clocks/voltages are stable and note the temps. I then run the stress test with a single thread and use a script to cycle the processor affinity of the thread every half an hour or so. This one is to test the Turbo/Boost/WhateverIt'sCalled clocks/voltages.

    I didn't realize that there was a Linux version--I'll check that out. Perhaps for my next board I'll get a Gigabyte, but I have been entirely happy with my Asus ones, so we'll see.

    And thanks, it does rather well :)
