"Technical" 1. go to BIOS 2. Raise multiplier. Alternatively, raise FSB. 3. If the computer fails to boot, increase voltages a little. If it still fails to boot, increase ram voltage. 4. Repeat 2 and 3 until you can't go any higher/are unable to boot. 5. ??? 6. PROFIT! | ||

While i'm no physicist, at that size we run into a problem called quantum tunneling. Although i don't fully understand the process, you can look it up on wikipedia if you're actually interested. Well, that's what I get for referencing 4 year old info on current technology.  Quantum Tunnelling, for anyone who's wondering, is basically like... you know how sometimes Dragoons miss their target, even on level ground where they're supposed to have a 100% hit rate? Well similarly, at very small scales, particles can do things they're not supposed to have enough energy to do. If you've studied chemistry, you've probably learned about the "activation energy" needed to initiate a chemical reaction, with the corresponding energy graph that looks like a hill. Well, Quantum Tunneling also involves a hill-shaped energy graph, where a particle needs to have x amount of energy to "climb over the hill" and do something. But the particle can do that same thing even if it doesn't have enough energy, as if it "tunnels" through the hill instead of climbing over it. Hence the name. So what does this mean for sizes smaller than 12 nm? I don't know: someone else will have to look that up or explain it.  | ||

For sizes smaller than 12nm we'll need to invent a new process to bring us into the era of "nanoelectronics" (that is, electronics on the scale of <10nm). Currently submersion lithography can only do so much, and i think if we perfect it we may be able to break the 9nm but it would be really difficult and probably won't be realized until we've all got personal reobot sex slaves and space ships. | ||

E6420 2GB Muskin DDR2 800 4770 512MB MSI P6N (Forgot which version, but it only supports up to C2D I think). And the shitty PSU CoolerMaster ExtremePower 550 or 600W God the damn thing sucks, the fan makes a very loud grinding noise or something and well I dont even need so much power in the first place. I regret getting it a couple of years ago, and yet I still kept it for this long. | ||

Look at all the switches that have taken place since the R300/GF4 days. Nvidia's had two bad series in a row but they just need one card like the 8800GT to turn it around again. I honestly regretted not waiting for the 8800GT or the 8800GTS 512MB instead of getting the 320MB G80. Oh well, it died on me few months ago. | ||

Fortunately this is wrong, with the use of heatpipe coolers and 120mm fans, even extremely overclocked chips run at most 55 degrees celsius. My i7 920 @ 4.1ghz on a CNPS10X EXTREME!!! (lol zalman) is currently running firefox and folding@home and running at a nice 48 degrees. | ||

and @ bill, curiously enough there's some complex analysis stuff i read in a book a few years back that was saying stuff about quantum tunnelling..pretty interesting how it can cut a route like that. | ||

The temps on my PC will get hotter when the new parts are installed, especially in the summer with stock coolers. 40 degrees is perfectly acceptable. What you need to worry about is load temps breaking 60. That will rape a processor in less than a year, whereas it's designed to operate constantly at temperatures higher than 40 degrees. | ||

not sure if what I said is right though | ||

I remember reading something on how as the processes become smaller, the distance between transistors becomes smaller and then volt leakages occur. not sure if what I said is right though It doesn't seem to be a problem they've run into so far. Other than the aforementioned "Quantum tunneling" i'm fairly sure they've fixed problems like this. | ||
