    bang-for-the-buck quadcore crunchers

    Hi all,

    About a week or two ago I put together the parts lists for some quad-core crunchers that a friend over at mersenneforum.org was getting. I "built" two hypothetical quad-core machines: one Intel and one AMD, both using comparable processors and motherboards (all the non-CPU-specific parts are the same), designed to provide the most crunching power for the least amount of money. My friend has now ordered, built, and set up four of the AMD machines, and is quite satisfied with them--so I figured, hey, maybe some of the folks at Free-DC would like one of these babies. So, without further ado, here's the specs, and links to the respective item pages at newegg.com:

    What's wrong with using the real links? if snipurl.com is offline, links don't work...

    Were you able to get any performance comparisons?

    Dedicated crunchers don't need cases, large HDDs or Optical drives, so prices would be lower.
    Nice list!

    Crunchers dont need Video Cards or large HD's.
    Also the q6600 is the farmers choice by a country mile.

    The 45nm quads are good but availability is patchy at present.

    I didn't include a video card in them, the motherboards have integrated video. As for the hard drives, those were the cheapest I could find--anything smaller, and all you'd still save no less than a dollar. Hard drives are cheap.

    As for the Q6600 vs. Q9300--the Q9300 was available when I put together the parts lists, though it appears to be listed as "deactivated item" now. I didn't know that there were availability problems with them, until now of course. The motherboard I chose will work for a Q6600 just as well as a Q9300, though, so you could easily swap one of those in and save a bunch of moola.

    Nice list!
    When I originally put together the list, the original links were a bit long and unwieldy in the forum PM that I sent the information to my friend in ([code] tags at mersenneforum.org display a little differently than here, so thus long links don't work so well in them). I just copied and pasted the info from the original PM in my sent folder.

    As for performance comparisons, my friend just got the machines set up before he went on vacation, so he didn't really get a chance to see how they performed. I'll have to ask him about it when he gets back.

    As for cases, large hard drives, and optical drives: well, you see, my friend isn't exactly ready for caseless machines just yet, in fact he isn't that terribly computer-geeky, and had a friend build the machines. As for the hard drives, those were just about the cheapest I could find--anything smaller was only pennies cheaper. And the optical drives are necessary to install the OS (that's why I just picked a bare-minimum DVD-ROM drive--you want to make sure it's DVD-ROM and not just CD-ROM since some OS discs are now DVDs), since a netboot thing is a little beyond what my friend was looking for.

    Since summers coming and Intel quad-cores run a little hot, would anyone be interested in exchanging a Phenom with a board with my Q6600 and board?

    I have to say that, last I checked, I was having throttling problems. Even after all the dust was blown out the problems only improved a little. Might be that I need a better heatsink, might be that I screwed up some settings and the temperature limits are too low, might be anything.

    Im waiting to see if there are any takers at all before I bother to give more information. Also, dont expect a response in this thread for the next 15 hours or so, unless you post immediately.

    Sorry if people think Im posting off-topic, I just figured that people that would want a new cruncher would most likely come into this thread anyway.

    why don't you put it back to standard settings for the summer?

    Reset the BIOS and away you go

    Is that possible? Ill look into it.

    Edit coming in about 10-15 minutes.

    Edit: I restarted it after resetting it. The way I knew it was overheating before was that I had a virtual console and overheating messages were being posted there by the computer. So, Ill start up a console right before I go to bed and see what happens. (probably an easier way, but Im still newbish)

    Try http://www.svc.com/acfzp7.html . 25 bucks (plus tax, shipping and the like). That's what I run on my 3ghz q6600's. I found the retail HSF couldn't handle much above 2.66.

    Spend a few dollars on a freezer 7 pro.
    Stock heatsink is carp
    All my quads have them and they run DC 24/7.

    IMHO
    Swapping a q6600 for a phenom would be a mistake.
    The q6600 is faster and the Intel chipsets are much better.


    BTW
    Is your q6600 a G0 or B3 ?
    It makes a big difference the B3 runs much hotter and doesn't overclock well at all.
    Run GPUz if your not sure.
