XC 25 na 40 :) nie badz smieszny ... chyba ze chlodzenie cieklym azotem zastosowales ...
twoja aukcje przykleilem nie po to aby cie "oczerniac badz kpic z ciebie"
ale tylko wylacznie dlatego ze jest dosyc wyrazne zdjecie
XC 25 pojdzie stabilnie na 33 mhz ..
The boards overclock the 68040's - the 28MHz one uses a 68040/25, and the
35MHz a 68040/33. PPI claim that these small margins are safe, given the
extra cooling provided, and they are probably right (I have had no
problems).
- Contrary to the picture on the box, the CPU clock crystal is soldered to
the board. I had toyed with the idea of replacing it (56MHz) with a 50MHz
one to bring the CPU back down into its specified range, but this put me
off
- The 68040 supplied was not a production chip, but was designated
"XC68EC040RC25". Contrary to my first angry conclusion, this chip DOES
have a full 68040 with MMU and FPU inside, but it has the less advanced
bus system of the 68EC040. Also, the "XC" designation means it has at
least one minor bug (in the design), and is therefore only for prototyping
purposes. I have, however, had no problems with it, and it performs in
every way like a full MC68040.
