    I can't overclock that thing...it's a Dell with a stock heatsink at work. The thing runs at like 60C as it is. I am running 5.2.13 with optimized BOINC. No hyperthreading...that particular chip doesn't have it. This is wierd. I don't know why they would be so far off. It's claimed credit for Einstein is always like 130-140 for about 30,000 seconds of work.

    I have another one exactly like it running which scores the same with optimized BOINC but it is running 4.45 optimized so it doesn't bench as high. Can't run the 5.2.X because of proxy problems mentioned in a different thread. That one with 4.45 gets...

    No HT explains your high numbers.

    Your 2.8Ghz performance numbers:

    Measured floating point speed 2489.47 million ops/sec
    Measured integer speed 4390.59 million ops/sec


    My 3.0Ghz performance numbers:

    Measured floating point speed 1915 * 2 = 3830 million ops/sec
    Measured integer speed 2150 * 2 = 4300 million ops/sec

    Not sure, but I read somewhere running HT often gives low benchmark scores - not exactly sure why as I don't own any.

    Also, another thing we've noticed is that sometimes with the latest optimized seti apps, there's no real advantage running 2 WUs in HT mode (eg, in HT mode you may complete 2 WUs in 60 mins, but in non-HT mode you'll do a single WU in 30 mins). It is possible the nature of the code optimization has totally eliminated any advantage of hyperthreading. Try a couple of benchmark runs with and without HT to test with the reference WU as YMMV

    Re: Welcome The Uncle B's.......

    You have to remember that with hyperthreading, you still only have a single CPU socket to transfer your data to and from the chip. So if you can reduce the amount of processing required in the CPU by improving your optimizations, then you'll increase the demand on the FSB. And if the FSB is near it's limit, then hyperthreading wouldn't make any difference. You're hitting a comunications limit of the socket.

    Yes, that explains beter what we were observing in some instances

    Is that one of your tactics to prevent us from spankin' 1 million points before you.?

    yea, ever since he started optimizing code, Ned has gotten even more devious!

    maybe changin diapers will slow him down!

    If you lose 2 WUs through running test benchmarks, but save 5 mins per WU from then on, you soon make it back up and then some.

    When I was doing test compiles on the optimized source code, I had a machine constantly running benchmarks for about a week. It didn't take me long to make it back up once I'd deployed the resulting optimized cruncher onto the whole farm

    ...but hey, what do I know

    Hey boyz - what happened to your estimated 70-80,000 dump... you only managed a modest 44,000:

    ...and I managed 30,000 all on my lonesome

    What do you mean? We had 224k when the problem started and now we have 300k+

    On those stats it shows our total credit as being 269k, that's old news we passed that number days ago
