best overclock 'c' series p4

which one is the best? either 2.4c, 2.6c or 2.8c

are the c series base on prescott core?

thanks

 

prescott is real hot..need good cooling

for me..although i dun own one i think 2.4C is great..coz it can really overclock..if u dun overclock get a higher mhz one's...

 

My personal experience with 2.4C:
I overclocked it to 3G (FSB 200->250) and it works well on an Abit IS7 (Intel 865PE). Of course I had to raise the voltage from 1.525V to 1.575V (the Northwood family si rated for 1.500 - 1.550 V). I also tried it for 266 MHz FSB (~3.2G), but memtest gives me errors (even with memory at 177MHz). But i don't know if it's the processor (probably the cache) or chipset(865). I would go for the chipset since further increasing the processor voltage makes no difference.
The first time I put it to 3G, I ran a test: recompressing a DIVX/MP3 AVI (to DIVX/MP3).
At stock voltage, it froze after 2 minutes.
After raising core voltage to 1.550V (maximum spec), it froze after 7 minutes.
After further raising to 1.575V (next possible step for my MB), it finished recompressing the movie after 2 hours.

But there is one thing you should know:
All processors (all frequencies from one family) are built on the same production line. They are marked I believe after a thermal test (well, it is a test). So a 2.4C is hotter than a 3.0C at the same frequency. After all, I got to 3G, but I raised the voltage over specifications (which directly affects power consumption/heat).

So I don't know how much you can overclock the FSB. But I think you can go to 250MHz on any Intel chipset.
I also think that any Northwood can handle 3.2GHz with proper voltage and cooler.

 

prescott is one hot chick!!

 

thanks for the reply

so how high can the prescott oc to? around 3.4 possible?

 

mine 2.8E can clock to about 3.5..dats 250mhz X 14

but need good cooling..mine temp kept to about 33C idle n 40C load cooled by xp-120 n a 145cfm fan
