I've had this Athlon XP 2800+ for no more than a year and a half, and its already soooo sloooooow <img src=" SRC="images/smiles/icon_wink.gif"> It's a 2087MHz chip, and I've only been able to get 2350MHz not quite rock solid stable, but that was in the summer. I recently polished my heatsink with lava soap and reapplied Arctic Silver 5. It's been about a week so the paste is broken in, and tonight its in the low 20's here (Texas) so I decided to see what I could do. My windows are open, my door is closed, I'm freezing, and my processor's temperature is topping out at 37?C under full load at 2350MHz, when it used to get up to around 52?C. I think I've got a shot at 2.4GHz or more this winter <img src=" SRC="images/smiles/icon_smile.gif">

So does anyone else here overclock stuff?

No, computer parts are expensive and I'd rather not waste them.

Its currently 19 degrees F here. I imagine that for some it would be balmy especially up north in Minnesota or the Dakota's

I wonder, after it gets so cold where is the line where more cold doesn't count? .

Oh yeah, I do not overclock, much. My vid card is run by "Powerstrip" and is about 4% or something over.

Overclocking, as long as you go about it right, is far less risky than you might think. As long as you have proper cooling and don't take your components too far and leave them there it's actually quite safe. When parts have been pushed too far they will have calculation errors that can cause instability (crashes/lockups). Prime95 is a distributed computing project to find new prime numbers, it also has a 'torture test' which stresses the CPU and memory by performing calculations and then checks the answers against what is known to be correct. When there is a miscalculation it means a hardware failure occured. That's when you either increase the voltage or decrease the frequency.

I don't expect to change anyone's mind about overclocking, just give the facts. <img src=" SRC="images/smiles/icon_smile.gif">

The temperature outside affects the temperature of your computer when your windows are open <img src=" SRC="images/smiles/icon_smile.gif"> lower 20's 'round these here parts is considered around -5 everywhere else in the world.

I tried 2.4GHz, but after a few hours of Prime95 it returned an error. Since the voltage was at 1.825V and a step of 50MHz was taking a bigger voltage increase each time I decided not to take it any higher. I backed it down to 2287MHz with 1.7 volts, just 200MHz and 0.5 volts over stock frequency and voltage.

The money I spend on extra cooling now I could save and get a CPU thats actually rated for higher clock later on.

Romm temperature does affect CPU temp. My temperature seems to vary by about 10C seasonally (idle 35 in winter, slightly under 45 in summer).

Underdog, theoretically you could make it colder and colder and keep getting potential increases in performance. I heard someone ran a P4 chip at 5ghz cooled with liquid nitrogen (-196C). The only limit, really, would be to make it so cold that it doesnt actually work. For only the CPU, I imagine this would be near absolute zero. For the surroundong components, probably much higher (-20C comes to mind).

Wilson, I was talking about outside ambient temps.

When you go outside and its 19 degrees F, would you notice if its zero?

Also, the open window cooling method for PC overclocking. Is that an optional feature of the event or is it required? <img src=" SRC="images/smiles/icon_biggrin.gif">

and, yes I know about cooling and such for processors.

Given the amount of insulation in the average home, its very unlikely that a difference of 20F outside would give a noticable difference in CPU temperature.

Put my geforce 6800 to I think it was 390 core, 790 mem on stock cooling. That was the furthest i pushed it with out artifacts.

I have a P4 3000MHz, but I dont think I will overclock soon, considering here in SA
the temp is about 35c!



I would love to change the world, But they would'nt give me the source code.

I've never tried overclocking my machine, partially because I don't want to do anything which would damage it, but also because I've seen what happened in this video.
