Hi, anyone knows how to calculate the heat output of a 1mb cache A64 ?

Roughly, multiply the clock speed by the voltage squared and multiply this by 0.0182 to get the heat in watts.
161w @ 2600mhz 1.85v? hmm....

Bring back the game. http://reclaimyourgame.com/. EA are mean.
Works like this, voltage is a square factor, frequency a linear one. Got the .0182 by using the stock 3200+ data of 81.9W, 1.5v, 2000MHz. Take a look at .this for a detailed explanation. 163W sounds about spot on. Going above 1.8v isn't child's play with the A64, much unlike the AXP.
eh? its not 160W!
yah 2600mhz with 1.85v is like 120-130 watts or so
can you see the light? is it shining too bright? can you see the light at the end of the tunnel, i know i do, i know its true.
And what are you basing that on?
I'm not sure if it is correct or not but Sisoft Sandra reports approximate CPU wattage at 106w and the formula gives me 107 and change. Seems like they are both using similar formulas whether they are correct or not.
