I've owned A LOT of CPUs in the past. 95% I've bought with the sole purpose to overclock them. I probably have one of the biggest overclocked CPU history. I got curious on this boring Sunday and decided to see the percentage of the overclocks I've had in the past. All of these were my primary system CPUs at one point. I've only had one complete system at a time if you can believe that.

Pentium 166C to 180 = 8.5%
K6-2 300 to 333 = 11%
Celeron 300A to 450 = 50%
Celeron 300A to 464 = 54%
Celeron 366 to 550 = 50%
Pentium III 450 to 600 = 33.3%
Pentium 500E to 700 = 40%
Pentium 500E to 750 = 50%
Pentium 650 to 910 = 40%
Pentium 650 to 1021 = 57%
Athlon TBird 1GHz to 1.15GHz = 15%
Athlon TBird 1.2GHz to 1.25GHz = 4.2%
Athlon TBird 1GHz to 1.35GHz = 35%
Athlon XP 1600+ 1.4GHz to 1.5GHz = 7.1%
Athlon XP 1800+ 1.53GHz to 1.6GHz = 4.4%
Pentium 4 1800 NW @ 2700MHz = 50%

Intel 10 CPUs = 43.28% average overclock
AMD 6 CPUs = 12.78% average overclock

Whats your CPU overclocking history?

Well, it's not really in the past since I'm posting this message from it :), but I have a P3 CuMine 866 @ 1202, a 38% overclock. I thought it was the most extreme OC ever until I saw that you ha(d/ve) a P3 650 @ 1021! :Q

Other overclocks:

P3 CuMine 667 @ 800 (my first OC! sold it a few months ago)
P3 Tualatin 1266 @ 1300 (preliminary)
Athlon MP 1200 @ 1440
Athlon Tbird 950 @ 1000 (preliminary)

Not counting my PII-350 which somehow OC'd itself to 361 and then back to 350 again when I switched video cards, my first "real" OC'd CPU is the one I'm on now, a P4 1.8A@2.7GHz :D

It is easier to list what I did not overclock, since ever other machine has been overclocked. So, my NON-overclock list reads:

Apple II+
Compaq laptop P233 (I think it was that)
Dell laptop P3 750

Thats my best overclock. That was during the time when everyone else who had the 650s were getting around 910MHz. I got a lot of compliments on that one. The CPU was a cB0 core stepping Coppermine running on an i815 with a bus speed of 157MHz. I sold it about a year and 1/2 ago.

Via cyrix 900 - 990mhz with the junkiest heatsink fan combo you have ever seen! I didnt even bother to re-apply AS II when I took it off once. This is in the old mans computer, and its due to come out and it get tossed.

Athlon XP 1.47 - 1.53Ghz. Sold it to my manager at work

P4 1.8A - 2.61Ghz This is my newest one, currently posting fom this computer.

P4 1.8A - ??? Dunno, it hasnt gotten here yet. I'll let ya know when I get it!

I think i tried to overclock a 486 before cause it was only the 1st generation @25MHz...<--- 25!!! but to what i don't know...didn't think it was successful

my list:
Pentium 166MHz w/ MMX to 200 = 20.5%
Pentium III 650 to 850 = 30.8%
(3) Pentium IV 1.6A to 2400, 2480, 2720 current rig <-- so far = 50%, 55%, 70% <-- so far
Pentium IV 2.4B to 2800 = 55%

Pentium II 300@333. Then upon selling it, discovered that the heatsink was warped, thus explaining my very high temps.
rolleye.gif
That was my first home-built PC. :)
Then K6-3 400@450.
Then the SocketA days came, and my processor generally didn't stay put for more than a month. I'd generally get at least an extra 150-200MHz out of them though.
Right now, my secondary system has an XP1500@1800 (I don't know the actual GHz rating offhand) and my primary system has an XP1700@1900. Both use Alpha 8045's for cooling.

not too many, still 2 record breaking Intel CPUs:


p200@227 = 13.5%

cel400@503 = 25% <--- baaad pci bus

cel366@633 = 73% !!! still running quiet at 605, 1,9v without active cooling in my movie box

Athlon Tbird 1100@1333 = 21%

Athlon Tbird 1333@1520 = 14% <--- my everyday box, a dork :p

cel600@990 = 65% <--- in my grilfriends box, 1.65v, pep66 non-active, soo quiet :)

Ahhhh, you nOObs! Sheeeit, I feel old. Seriously, I have grey hairs on my head (maybe from too much stress). Lemme see if I remember... This is NOT necessarily in order of time of ownership, but is in order of original MHz. No commentary means it worked, and worked well. Not listing ones I had which I didn't overclock, or which did not want to overclock. I'll also list some chips I had a hand in overclocking, but will attribute the owner. Also, plenty other systems that I messed with, but didn't own - won't list them, too many.

Ancient history to socket 7:
i 386DX25 @27
i 486SX25 @33/40 (CPU died after only a few hours, it was an old one when we were already into Pentiums)
AMD 486DX2-66 @80
AMD/Cyrix 486DX4-100 @120 (actually a buddy of mine - anyone remember Pimpdaddy/Nowhereman from Off Topic? owned the Cyrix)
AMD 5x86-133 @160 (well, briefly and not too stably)
AMD K5-90 @100
i P120@133
i P150@166
AMD K5-166 @200 (I loved this chip, but system got stolen :( in a burglary, Nowhereman also owned one)
i P166MMX @233 (owned by a customer who bought it at a computer show as a 233. It died and we pulled it, to see 166 on the bottom)
AMD K6-200 @225 (another one I loved, great performance at the time)
i P200MMX @225/233/249 (I kinda borrowed this one, LOL, those MMX chips had headroom to spare it seems)
AMD K6-233 @249 (owned by Nowhereman, this was the best of the best... briefly before Intel came out with P2)
AMD K6-266 @300 (I think it's still in my Q3 Demo server, hehe)
AMD K6-2 333 @350 (used it for quite a while, good system but I was really disappointed with the low overclock on my Asus P5SA)

Recent history:
Celeron 300a @450 (of course. First one went to my GF actually, because the Abit BH6 mobo didn't like my Adaptec SCSI card, so I went back to the K6-2 for a while until I got a Shuttle board - used electrical tape to mask pins to do voltage, hehe)
Celeron 366 @550 (all my friends had one)
Celeron 533a @800 (got it from that guy Steve, who sold pre-tested chips - forgot his handle here - and it is still working today in my TV/media machine on an Abit BM6)
P3-550 @825 (150FSB on Asus P3B-F, couldn't find any AGP cards that liked 100MHz, so used a PCI Voodoo3 2000. Rock! I'm still using this chip today, in fact RIGHT NOW ON THE machine I'm typing this message on, on an Asus P3V4X but only clocked at 733. Don't know why, but it was stable at 150FSB on the other board but won't even POST on this board at that speed)
Celeron 566 @850/9XX (my GF had one, now her parents use it. A buddy of mine has one running somewhere over 900, since replaced with Tualatin - see below)
P3-650 @911 (belonged to friend)
P3-700 @933 (had two of these, still have one sitting in drawer after replacing it with a modded Tualatin)
Duron 900 @1GHz something??? (was just screwing with it on an Abit KG7-RAID, reducing mult. and increasing FSB. Got pretty high on FSB and then my Crucial DDR died. CPU is sitting on my desk at this moment)

Modern Era:
Celeron 1.0A @1330+ (great chip, default voltage. Gave this to my buddy as a wedding gift, LOL. I'm such a geek)
P3 1000 @1330 (yes, a rare Coppermine 100MHz FSB socket CPU, needed &uuml;ber-cooling to overclock stable, so sold it to someone here with full disclosure)
Celeron 1.1A @1460 (still use it at home)
Celeron 1.2 @1560/1600 (1560 on VH6T, then modded to run on BX133 mobo and it now runs 1600)
Athlon 1.2 AXIA @1400+/- (was my GF's, it ran for a bit, then it didn't seem stable anymore. Dunno, but I had a lot of problems with it on an Abit board, some KT133A jobbie, sometimes it would run fine, other days it would lock up even UNderclocked to under 1GHz)
Athlon 1.4 @1.6 (totally different beast from the 1.2, it was stable and overclocked like a champ with very little voltage boost on a Shuttle AK31 rev2 KT266, not KT266A, belonged to one friend, who traded it to another, who traded it to another now away at college)
P4 1.6 @1.7+ (Willamette core, P4X266 chip mobo, no vCore adj. and the board undervolted to around 1.68v but still was able to crank it up a bit. My first attempt at a "quiet" system since the retail HSF was so noiseLESS, still in use at default speed here at work)
P4 1.6a @2.??? (first Northwood, on both a Gigabyte 8IRX - didn't know it did NOT have vCore, and an MSI 645Pro. Didn't have good results, sometimes it would work, then I would get strange errors like the Gigabyte 845D board not POSTing, gave up and sold the stuff)
P41.6a @1.6 haha (ran okay at 2.16 or so on an AOpen mATX 845D board, but it also had problems POSTing. If it POSTed, it was rock solid stable. If it DIDN'T POST, can't use the darn thing. My GF uses it now at default speed and loves it)

Even though I play 3D FPS games and I have friends with GF4Ti cards and P4@3GHz, I'm still pretty happy with my various socket 370 CPUs. Got a bunch, but if I were to include the ones that are in complete systems and in operating condition...
Celeron 533A @800 (media machine)
P3-550 @733 (work machine)
P3-700 @??? (just swapped CPUs with the Celeron 1.2, haven't messed with it yet)
VIA C3-933 @933 (my carry-around machine that I use to smooch broadband off other people for downloading, LOL)
Celeron 1.1A @1.46 (my "main" machine with ATI7500AIW, 280GB disk space, all my good stuff)
Celeron 1.2 @1.6 (just swapped CPUs with the P3-700, seems stable after hours of benchmarking)
Athlon 1.4 @1.4 (just built the system from spare parts, trying to sell it, 7200RPM RAID, GF3, SBLive, etc.)

Plus, I've got enough parts to build about 8 more complete (but lower end) machines, and tons of parts beyond that.

P4 1.6 @1.7+ (Willamette core, P4X266 chip mobo, no vCore adj. and the board undervolted to around 1.68v but still was able to crank it up a bit. My first attempt at a "quiet" system since the retail HSF was so noiseLESS, still in use at default speed here at work)
P4 1.6a @2.??? (first Northwood, on both a Gigabyte 8IRX - didn't know it did NOT have vCore, and an MSI 645Pro. Didn't have good results, sometimes it would work, then I would get strange errors like the Gigabyte 845D board not POSTing, gave up and sold the stuff)
P41.6a @1.6 haha (ran okay at 2.16 or so on an AOpen mATX 845D board, but it also had problems POSTing. If it POSTed, it was rock solid stable. If it DIDN'T POST, can't use the darn thing. My GF uses it now at default speed and loves it)

Even though I play 3D FPS games and I have friends with GF4Ti cards and P4@3GHz, I'm still pretty happy with my various socket 370 CPUs. Got a bunch, but if I were to include the ones that are in complete systems and in operating condition...
Celeron 533A @800 (media machine)
P3-550 @733 (work machine)
P3-700 @??? (just swapped CPUs with the Celeron 1.2, haven't messed with it yet)
VIA C3-933 @933 (my carry-around machine that I use to smooch broadband off other people for downloading, LOL)
Celeron 1.1A @1.46 (my "main" machine with ATI7500AIW, 280GB disk space, all my good stuff)
Celeron 1.2 @1.6 (just swapped CPUs with the P3-700, seems stable after hours of benchmarking)
Athlon 1.4 @1.4 (just built the system from spare parts, trying to sell it, 7200RPM RAID, GF3, SBLive, etc.)

Plus, I've got enough parts to build about 8 more complete (but lower end) machines, and tons of parts beyond that.

Dang! Now thats serious. I'm willing to bet that you have this saved somewhere as a text document.
