    I have moved my stats-making from the morning to the evening. Therefore the current period is 1½ days and not just 1 day.
    Here are the stats for the new teams.

    Thanks for the stats Peter. As for my GTX 460 issue, looks like it might be a temperature thing. Did a stress test with OC Scanner and the card hit 100C which caused throttling. Stupid thing is the fan didn't spin any faster. Looks like I will have to do a custom fan profile to get the thing to run cooler.

    Yep no advantage to crunching beta WUs on ppd. Although with FAH, ppd varies quite a bit depending on the WU/project. Some things never change. :whiste:

    Message from diwalker (project scientist) on the beta forum:

    "I am moving projects 8072 8073 8074 to advanced now. Thanks."

    I'm getting about 16000 ppd on GTX460 and almost 21000 ppd on
    GTX570 for these WUs.

    I set all my cards to at least 70% 24/7/ I have a card that does 100c @ 75% fan (560ti) Its mate does 65c, the problem is no space between cards, and I have one extra fan in there as well.

    Yeah. I was testing a system that was like that. 2x GTX 690's. Right on top of each other (only 2 PCIe slots in the system). Bottom 2 GPUs ran at 85C and the top 2 ran at 98C. Lots of issues with the system.

    Well the 690 only has a single fan. Get a custom cooler?

    My 460 is the only card in the system with two intakes and two exhausts so there's plenty of airflow. Despite that, it still still managed to hit 100C. When I get a chance, going to open it up and make sure the fan isn't on the verge of dying and give it a blast of air to rid of the dust.

    Well, it's atleast very unlikely anyone will run into any heating-issues with Amd-GPU's in FAH...

    My wu finished earlier to-day, finishing at an average of... 1134 PPD. :rolleyes:

    Now, granted, part of the time did use the computer for other things, but even for "idle" periods was only at around 1600-1700 PPD. D:

    Well folded, TeAm-mates! The racers produced 88.9% of all points today. :)

    Anybody else with 460's getting poor PPD? I am brand new to folding but the first couple days I was getting 35,000+ PPD with 2 GTX 460's and a Phenom II X6 running SMP:4, and for the last couple days I'm getting < 25,000. There are 2 differences, I unhooked my monitor that was hooked to it since it was worthless to use the PC while GPU folding, and also set client-type advanced to try to get some beta units. Just curious if maybe it's just the WU's I'm getting or may be related to the other 2 things.(unhooking monitor and setting client-type advanced)

    somebody talk me out of a new 32 gig 24 core interlagos motherboard/cpu/memory...

    its only $1400 and I have an AX850 to power it. Will that work ? 2 8 pins and the 26 (or whatever) regular ?

    I have 6 460's, right now 5 of the 6 are doing 10k. One is doing 23k. Its the units. What unit are you crunching ?

    I have 2 rigs running win 7 with monitors detached. No effect on ppd. It all depends on the WUs you get. 8054 WUs will give you ~10,000 ppd on GTX460 while 762x or 807x WUs give about 16,000 ppd

    PPD is going to take a little bit of a hit. Had to shut down the SMP folding on my FX8120. The core temp was skyrocketing to 70*C+ for some reason. All fans running normal. Dusted it, restarted and same thing. Wondering if the pump on the Antec Kuhler 620 is starting to go? It doesn't make any noise (have 5 case fans plus a push pull setup on the radiator).
    I let things cool down and now at idle it's running 35*C.

    Just plain bizarre. I do have a 212+ sitting around that I can swap in one of these nights.

    I have a kuhler 620 on a 1055T and it is only at 52*C full load. The FX is upstairs where it is warmer, but that doesn't account for the temp (another 1055T with at 212+ full laod is at 50*C).

    I think that would work... more research needed... why 24instead of 32? :)

    It would work. I regularly use Seasonic X power supplies (2x 8pin and 24-pin) on dual-socket motherboards. But what exactly are you getting?

    AMD Opteron 6234, a dual-socket motherboard like the H8DGi-F, and 8x4GB DDR3 ECC-Reg?

    TBH, I'd rather get dual Xeon E5-2620, a dual socket 2011, and 8x4GB DDR3 ECC-Reg for basically the same price (2x$400 + $400 + RAM). Folding@Home and other distributed computing projects often rely on heavy FP computation and Bulldozer won't really give you any advantage as it's really only 12 FP cores. Abu-Dhabi/Piledriver (the Opteron 6300 series) will give you a little leg-up over Bulldozer because of it's second-gen optimizations in scheduling/etc.

    That will be 12 cores total, 24 threads, vs 24 real cores. and 2.4 vs 2.0 speed. Now I know the intel is faster per ghz, but enough to make 24 threads on 12 cores faster than 24 cores ? and with a significant speed difference ?

    and my PSU is a Corsair AX850. It will have 2 GTX460's in it also, and 4 hard drives.

    :D

    Mark, I think that you'll find the Intel solution really is just about as fast, or faster, while being more efficient and being a platform that has a lot more headroom.

    You need the threads to get into big-adv...

    Either way, I would actually advise (free Internet advice! Woohoo!) that either way you go, get the biggest CPUs you can afford, even if it is just one socket now. For example, get one of these for AMD:

    16 Way Abu-Dhabi
    http://www.newegg.com/Product/Produc...82E16819113306

    Or for Intel:

    Intel Xeon E5-2640
    (2.5 Ghz hexacore)
    http://www.newegg.com/Product/Produc...82E16819117267

    OR swing for the fence
    Intel Xeon E5-2680
    http://www.newegg.com/Product/Produc...82E16819117262

    WHY SO MUCH you say? Here is the deal - Folding rewards density. The big boy Intel or the Abu-Dhabi AMD get you into the magical big-adv world all by their lonesome by filling one socket... and then you bring the pain (and get the points!) when you can afford/decide to fill in that second socket. That will probably increase your PPD by 50-100% of its current total. A four way AMD box or a dual octo-core Intel box is going to get pretty crazy.

    Also, figure one AMD core is only worth 60% of an Intel one. It gets closer when you compare cores to threads, but many times Intel is still faster even when its mhz is slower. Look at cinebench results (a massively threaded application) and an 8350 (8 core AMD, 4 ghz) loses to a 3770k every time despite more mhz. http://www.legitreviews.com/article/2055/12/ Let's overlook the fact that AMD uses ~30% +- the power to come up with that result.

    Folding CPU ppd is all about density. Unfortunately, that costs money. But you could have a 32-way AMD box for pretty "reasonable" - it really is amazing what spending ~$2500 can get you in a computer these days. Think back fifteen years - that's what it took to get a really decent PC for your desktop!

    Very interesting. Can those two boards really take i7-3930 (or similar) CPUs?

    Well, I am kind of screwed, as I its already shipped.

    Damn.

    Only Xeons have the extra QPI links to run in multi processor configurations. The 3930K is basically a consumer Xeon with a QPI link disabled thus it can't be used in 2P configs.
