    I'm out of town for 15 days and will keep my Pentium D 840 XE system running during this time. The objective is too find how stable an air-cooled Pentium D system is when it is running with all 4 CPU at 100% load for a sustained period of time.

    • Abit AW8 Max
    • Pentium D 840XE (HT enabled)
    • 2 x 515 MB + 2 x 256 MB DDR2 ar 3-3-3
    • Aircooling with XP-120 + 120 mm fan running at around 1,500 rpm
    • 1 x Hitachi 160 PATA HDD
    • Radeon X300 Pro
    • 1 x 120 mm exhaust fan

    The room temperature is currently around 30~28 C. Outside temperature toady was 34C. The system is folding with 4 F@H instances. I will not run a webcam like THG :lol: , but everybody can follow up how the system is moving (or whether it's dead) by checking:

    http://folding.extremeoverclocking.com/user_list.php?s=&t=24&p=4

    I have 2 systems running: 1 P4 2.6 that makes around 200~300 points per day and the 840XE system that makes around 500~ 600 points per day. Both systems should produce not less than around 11,000 points within the next 15 days until I am back. If the dual core system fails, it would be not more than 4,000 points. Current status is 81,012 points. If the Pentium D system does not fail, my total folding score should be at least at 92,000 points on July 11.

    good one.....those P4s are producing some good points for you...i thought that DC one would do around 800 points a day....just comparing to a Dual Xeon HP Server I ran for a short time at 2.8GHz 1.5GB RAM ECC PC2700, U320 SCSI drives....i read somewhere that AMD CPU in single mode still do less than Intel in single mode....didn't sound right but hey Intel is Intel....damn it chainbolt you're infecting me with Intel upgrade bug again with those mouth watering pics...i might pickup a cheap setup just to play with it a bit...hopefully one of my mates is looking for a PC upgrade i can offload it when i get sick of it

    The system is still running after 8 days aircooled with all 4 CPU at 100% load and folding like hell. 89,000 points as of today.

    The temperature in Tokyo is well above 30C with very high humidity, because of the rain season. Must be a terrible stress on the system. Of course it's hotter here, in Phuket at the beach. :leet: :leet: :leet:

    we have one of those processors in the showroom at work on an intel es board and i gotta say they are bloody stable it pretty much runs nvidia demo's on a 6800U (not a huge strain on the processor at all i know) but yeah gets warm and is 100% stable...

    Don't forget your blockout cream and wear a hat or you could be a candidate for the Big C on you skin, then you'll be really grateful for the folding@home projects that we contribute to. ;)

    If you're doing any diving in Phuket, drop by Bottom Time Diving and say hi to my mate Jerry who runs the place. :)

    The system is now running without any interruption with all 4 processors at 100% load, aircooled as shown, 24/7, since June 26. The room temperature is well above 30C, outside 30~30C at daylight.

    it's a pity that we still have to explain this being in such a fierce competition with [H] for the world's fastest folding team. It should be mandatory for every able OCAU member to join the team. :p

    well observed, it's a 75 CFM, 1200 rpm, high profile 120 mm fan with a aluminum chassis from "Cooler Master".

    The aluminum works as a kind of extension to the XP 120. And Cooler Master gives a 100,000 hours life expectancy for this fan in stead of the usual 50,000 hours. I don't know though what this has to do with the aluminum frame (they say it has).

    The system is still running without any problem. At daylight the ambient temp is now at 30C, CPU temp between 59 and 61C.
