Quote from: Moose on February 10, 2008, 04:32:22 pmThis is actually a lottery in whether you get a good chip or not. I recently bought a Yorkfield and it's a bit of a stinker to be honest - well there're faster ones out there is what I mean (Mr. Jobs must have got mine). They'll do what they say on the tin, but anything above that is in the hands of the gods. I can get to 3.8Ghz without going above 1.33v (bios) but there are others who can get theirs in the mid 4s on air with far less voltage. I was hoping for more from mine... though mustn't grumble, eh.If you read any of the posts over on - www.xtremesystems.org/forums/index.php? - there's alot of people putting volts close to what they did with their Conroes through them, and suffering degradation already. Basically the 45nm process seems to be a lot less volt tolerant, even when considering the die shrink. Intel say the max safe is 1.368v (or something like that) with 1.45v being the ultimate max (i.e. expect to suffer degradation at anything over 1.368v though the chip should still function at 1.45v) - this hasn't stopped people in thinking that 1.45v is safe for 24/7. Of course, how much leaniency Intel have built into their figures is anyone's guess, plus every chip is different anyway. Needless to say, being the scaredy pants that I am (or poor ) - I shant be putting more than 1.35v through mine (not at least without a bios update which opens up the margins a little again), but each to their own...I notice you haven't specified a cooler (or are you going to go with the stock one?). If you're looking for a recommendation, take a look at the Thermalright Ultra Extreme 120 - http://www.thermalright.com/new_a_page/product_page/cpu/u120ex/product_cpu_cooler_u120ex.htm?art=MTQyMywxLCxoZW50aHVzaWFzdA== - keeps my chip so cool that I've had to disable the consequent low fan-speed warnings which are forever sounding. It's cheap for what it is and'll keep your system quiet.I hope you get a good chip - good luck.

One in x-thousand or x-hundred can snap HDR, which is how one maker of an HDR camera can offer such a thing. They buy sensors in bulk and test each one.Back to the topic.
