Then that 1.6a was quite sweet cause it did 2.53ghz at default voltage and I amsure the stock hsf could have handled it since at 2.4ghz I tested it and the temps hit 58c under load.....
Thermal throttling wouldn't have hit inn until 66-70c and that would have been if the reported temps are even trustworthy....
Where those the c1 stepping chips that seem to have promise but many didn't get them to deliver better then the end og the B0 stepping line???
AIUHB 2100+ hits 2.5GHZ, for an 800mhz OC on just about any heavy duty air cooled system. On TEC/Water, TEC/Air, it easily hits 2.6 and higher. Mine topped out at 2.62 with TEC/Air cooling, for a 900mhz OC. Where's it at on the list?
hmm....
i dunno if overclockability should be measured by percent or by how much of an overclock you can get...
example...
1700+ stock is 1.47 and overclocks easily to 2.4 ghz which is almost a 1 ghz overclock or 1 ghz / 1.47 ghz = ~70% overclock
2.4C stock is 2400 and overclocks easily to 3.5 ghz which is a 1.1 ghz overclock or 1.1 ghz / 2.4 ghz = ~46% overclock
in pure speed, the 2.4 overclocks higher but percentage the 1700+ wins....
i think you need to state a standard... either pure speed or percent...

well p4 1.4m at 2.9ghz is 1.5ghz / 115% so I still reckon thats the winner, and the fact it cost me just $32 is an added bonus

Can everyone get it for that price??? If so that would be a winner....
Have a look on eb@y, who wants to buy a mobile p4 at only 1.4ghz? they are unwanted and slow as ass, until you put them in a 8x5 mobo and hit 200fsb+. I have 2 of them and bang for buck cant be beaten.
The most OCable CPU I've had is my 2100+ AIUHB which hits 2700+ (simple 133 -> 166MHz FSB) at default voltage of 1.6/1.65V. My P120 would only get to 133MHz and my PIII 866 to 956 MHz in comparison (VIA Apollo 133A Pro). They did have poor mobo's in terms of OC features though.

One of my old machines has a Celeron 300 - could I pump it up a little? Whats the best way to improve this crusty relic?

Yeah,
I can't believe the Celey 300A was left off. The standard OC for that chip was 450 mhz... that is a 50% OC, and beat's most if not all the others listed, which are closer in range to 25 - 40% OCs

The JIUHB Athlon1700+s are known to hit 2.5ghz or so. 2.2ghz was considered is BAD OVERCLOCK. With a stock speed of 1.47ghz...
2.2ghz = 50% OC = 735mhz OC
2.5ghz = 70% OC = 1029mhz OC
Athlon 1700 JIUHB > Celeron 300a
Though, the Celeron should be on the list, as it was pretty much the first great overclocker.

ok i finally went back and dug up some material, and my original claims were slightly exaggerated, but hey, i was trying to remember somehting i had seen years ago. anyways, i found the website and the chip turned out to be a Celeron 566 (which had a coppermine core). so i don't know if this thread was intended to identify the highest practical overclock, or literally the most overclockable CPU ever, as the title says. but anyways, this is by far an unconventional OC, and until liquid nitrogen cooling (or however they cooled it) becomes the norm, this was just for experimental purposes only. this celery hit 1.148GHz. that's a 103% OC, more than twice its stock speed. i dont recall how stable the system was, or any other details of that nature, but just take the link above and read it for yourselves...its old, but interesting.
i'd say Mingon's P4 1.4M @ 2.9GHz is the most OCed chip i've seen, both in Hz and %. its actually only a 107% OC, but that beats the celery's 103% OC. and his 107% OC = 1500MHz, while the celery's 103% OC only = 582MHz. hey Mingon, what kind of cooling are you using?
