Pentium D 805 ascends to the throne as the new King of OC

[desilver]

We bought an Intel Pentium D 805 from a local retail outlet and overclocked it up to 4.1 GHz, even though this part runs by default at just 2.66 GHz. This represents a heretofore unattained clock rate increase of just over 54 %, for which only some additional cooling is required. The secret is in the FSB clock rate, which is raised from 133 MHz to over 200 MHz; the system remains completely stable, because modern motherboards with Intel 9xx chipsets are laid out to handle FSB clock rates of up to 266 MHz. In language that overclocking enthusiasts will love to hear, the Pentium D 805 ascends to the throne as the new King of overclocking, knocking out the AMD Opteron 144.

You fool, you're completely wrong. Going all the way back to the PIII 500E which could sometimes be clocked to 1000MHz, we have many processors to beat the 805. Even now the 805 is easily beaten by the Celeron D 310 and 311, both of which go from 533 to 800 bus with NO cooling upgrade (the same as taking the 805 to 4GHz), and it can be overclocked by a whopping 65% on better air cooling.

OK, lets put some things together:
1a.) 533 to 800 bus on the 805, a 50% overclock, requires ~1.65v core and maxes out the huge Zalman cooler. In fact, this is the actual limit THG found for longer testing, 4.0GHz, and really needed something more than the Zalman cooler.
1b.) 533 to 800 bus on the 310, a 50% overclock, can be done at stock voltage, and the stock Intel cooler barely gets warm.

2a.) At voltages high enough to kill the 805 quickly, it can reach 4.1GHz. This requires water cooling at a minimum
2b) At 1.50v the 310 can still run at stock voltage and used stock cooling!
2c) The 310 can ultimately go well beyond 60% and overclock.

Sorry, but 54% just isn't enough, especially when the Celeron D can do more, at half the CPU cost and 1/4 the cooling expense. It's far from a record, I've seen PIII's overclocked 100%!
