    I'd be more impressed if the CPU was Prime95 stable for 12 hours. :D

    Basmic - Orthos stable at 3.8 - I only ran 3 hours because a forum I follow accepts 3hrs. It did not fail orthos ,I stopped it. Of course it's flakey over 4 ghz but not bad for a cpu not good enough to be an E8*** or e7*** and bought for £49 last week, off ebay, with cheap Adata ram and £10 psu - ram will run at 1000+mhz and 4-4-4-12
    My system is so unstable that it won't pass Intelburntest even at stock
    Saying that it only bluescreens when I set something too far, never crashes or locks.
    Wish I'd got an E8400 last year when they were under £120

    A lot better than 15.406! Low volts as well. Is that orthos stable?
    What mo/bo do you have ? Will it do 5ghz ? I've read 1.45v max for 24/7 use - but I've gone upto 1.6v for a suicide run.
    Now I want an E8600!!!
    http://www.pcstats.com/NewsView.cfm?NewsID=64899 says 3.6 is the sweet spot.

    Sammy Netbook NC20 running Windows 7 1m 33.366s
    Pentuim 4 1.6Ghz 2GB RAM Vista Ultimate 1m 54.375s

    My little Sammy NC10 XP managed it 1m 34.5seconds while reading the rest of the thread.

    edit for the record, my desktop E8500 3.16Ghz dual core vista machine managed 15.53seconds so I think I`ll play my games upstairs!
