Ok here we go!!!

Mine :-

PIII650@929 runs ok but a bit unstable with agp at 95. It run at 962 for about five mins all with standard intel heatsink+fan

Abit BX6r2 pIII650@929 at 1.85v using mircon ram, and diamond viper v770
 
If you are going to start this kind of thread, you might as well give complete system specs including the stepping of your chip, core voltage, type of RAM and relevant bios settings. Otherwise the OC number is meaningless.

If the idea is just to say "Ha Ha, my CPU is faster than yours" then OK go ahead, but it would be more interesting to help others with the same hardware to achieve your results or at least diagnose what's holding them back.

Good luck.
 
Highest (%): Intel 486SX 25 to 40. Man that was a rocket!
Highest (mhz): Amd Athlon 650 to 850. Momma was complaining about how slow her Intel PII 266 was.........
Hardest: Cyrix PR300 to 300- I just did that one to prove that you COULD O/C a Cyrix! Of course, with a H/S 4"X 2"X 2" & 2 case fans attached, heat was not a problem!
Best Bang for the buck: Amd K6-2 400 to 522. Used it for myself over a year- sold it to my Mom as part of a upgrade. Still soldiering at 500 in her system. Dang good IMO for a $65 chip
Next: Amd Duron/Tbird. We'll see about those "multiplier locks"!
 
My best is a P3 650 at 910MHz with 1.7 volts. I can probably go higher, but my Asus P3B-F goes from 140MHz FSB to 150MHz FSB, so it's hard to make that big jump in bus speeds. I should have an i815 to test out, so I'll see how that goes.

I still have a 500E that does 750MHz at default voltage, and possibly more, but I have yet to find a motherboard to run past 150MHz FSB stable. Perhaps the i815 would push it a little higher.

BTW- Is anyone out there running an overclocked CPU on an i815 based system yet?
 
I've got a PIII 700E cb0 sl3xx@980MHz on an Asus CUBX, 1.75V. Like Adam, I can probably go higher, but the jump from 140 to 150MHz seems to be a tough pill to swallow, especially for my vid card. I've run cpu stability hardcore for 12 hours straight with no errors at 1050MHz and 2D works fine, but as soon as I go into Q3A or any other 3D app my vid card wimps out. A local chop shop where I lives claims to have the Abit 815 m/b in stock, so I might pick one up Monday depending on what I find out about the Abit being good/bad. The FiringSquad article about it was not very favorable, but that is a whole 'nuther post/argument.
 
Abit IT5H Rev2 and Pentium 233MMX @ 3.5 * 83 for 290 MHZ Retail Processor with Stock fan and heat sink. Still going strong. It ain't the fastest but it once was.

Abit BP6 with 2 Celeron 500's @ 7.5 * 80 for 600MHZ it ain't the fastest either but it also uses retail fans and heatsinks and does 3.42 Mkeys/s on RC5
 
This is a 566celeron that I picked 'cause it did 1003mhz with air cooling@1.8v. I got it to replace the 566 I had been using. With my cooling rig, it currently runs stable at 1088mhz for 522mhz overclock. It will run in windows but no games at 1139mhz, or double the 566mhz chip..573mhz overclock. It will post into Windows higher and I have seen it post into dos at over 1200mhz. Very stable and damn fast...

 
Athlon 750 overclocked to 1018. Will try for 1100Mhz once the cooler for my water cooler comes in (freeze down the water in the water cooler).
Highest hit with post but no stability so far: 1044Mhz
Stable as a rock at 1018
 
Cel 266@417 - BH6
Athlon 700@777 K7M, little voltage tweaking
2*Cel 500@566 BP6, little voltage tweaking
PIII 650E@810 BH6, little voltage tweaking

All with standard cooling !

Together nice stuff for a cow !
