CPU's you've owned and OC'ed ?

[zach0624]

i'll start with my first oc because I can't think of what cpu I had before that.
athlon xp1600+ at 1600mhz
this was my first oc and since it was first oc I didn't want to push it farther mydad would have killed me too.

athlon xp 2600+ at 2200mhz
I got a volcano 10 and as5 for this one. was my gaming rig up to just a few months ago. I had had a ti4200 for about 2 years and then I convinced my dad I needed a fx5950 (400 after rebate) after I killed my 4200 when I pulled off the heatsink.

athlon 5600x2 @ 3150mhz
this is my current gaming rig and first overclock when I actually pushed my components.

god I miss my computer. I'm at camp and it took me 15 minutes to type this post.

My upgrade is in route with Fedex, so let me reflect on my past experiences:

Bought an AMD 5x86-133 and was hoping to overclock to 160. I took out my AMD DX2-80, which I assumed was a 3.3v chip and droped in the new one. Black screen. ACK! I soon realized that my old chip was 5v and I had just fried the new AMD 5x86-133. Still have the chip in a drawer somewhere as a lesson for me. Ended up using the DX2-80 until I sold the machine

PII 300 @ 300. PC Chips board couldn't do anything, and I doubt the chip had any headroom anyway

PIII 550E @ 770. This chip just flew! I think I overclocked it before I even installed Windows on the new build. I believe it got up to 820 but was unstable, so I liked the round number 770. Gave the machine to my sister, and I think she still runs it at 770.

AMD Athlon 850 @ 850. I had delusions of achieving 1 ghz. I couldn't even reach 900 stable. I took a detour into water cooling which didn't help at all. Considered using a peltier or building a refrigeration system, but gave up. Uh... I didn't seriously consider refrigeration... just... thought about it. Gave the system to a friend when his computer was stolen when moving.

PIV 1.6 @ 2ghz. Finally got over the ghz barrier, but way late in the game. Decent overclock, but not like the PIII 550E. Recently it hasn't been stable, so I slowed it to stock speeds. I suspect it is the dust in the Zalman cooler. Haven't bothered to clean it because....

Core 2 Duo E4400 en route. I plan (hope) to fire her up at 3ghz before installing Windows and never look back.

 

[clarkey01]

AXP-M 2500 @ 2.5 Ghz - That was sweet

Im soon to overclock my 6600 before I get a quad.

 

[Yanagi]

386 DX-25
First CPU, never overclocked

486 DX4-100 Mhz
Did not overclock

AMD K6-233Mhz
First PCU I tried overclocking, think I managed to raise FSB to 75Mhz, but this was such a long time ago I forgot the results.

Pentium II 233 Mhz @ 266 Mhz
Not much of an overclock but still an overclock

Celeron Coppermine 600 Mhz @ 1017 Mhz
My first real sucessfull overclock breaging the 1GHz barrier for the first time. It was an awesome feeling, too bad the celeron was too crippled in the end.

AMD Athlon Thunderbird 1.4GHz @ 1.6Ghz
Not really much of an overclocker, but the thunderbirds were not particulary easy to overclcok, they ran hot aswell.

AMD Athlon XP 2100+ 1.73GHz @ 1.9X GHz (Palomino)
This is the older Palomino core which did not overclock that well.

AMD Athlon 64 3500+ 2.2GHz @ 2.6GHz
My second overclock I liked, nothing to be really proud of but it was still a good 18% overclock and the best is that it was free. Overclocking the CPU was a bit of a hassle at first since I didnt really feel at home with the whole hypertransport tjingamajig. Took a while getting used to.

Intel Core2Duo E6850 3.0GHz @ 4.2 Ghz
This is my current rig. I really like this CPU the best of all my CPUs i've previously owned. At stock this chip is already mindblowing fast in my opinion. This chip does 3.6Ghz at 1.35 VCore which from what i've seen is very good. Getting the chip stable above 4GHz was a bit of a hassle. It needed far more VCore than I really wanted to for 24/7 use but it was bench stable, orthos stable and superPI stable. I'm thinking of jumping the penryn chip when those launch but will most likely wait and see the results first.

Time to climb into the way back machine....

My first computer was a Commodor 64..

I'm sure I will miss a few in the middle.... BUT as I recall..

I had an original IBM PC (2 floppy drives, NO HD,monochrome baby, 256K RAM)
I upgraded to an IBM XT (10 MB hard drive, 640x480 RGB, 640K RAM)

That was the early 80's, the XT, with an epson dot matrix printer, cost $7200.. in todays dollars that's about $14000... OUCH

After that I went to a compaq 80286 luggable suitcase computer, held onto that for a few years.. I think that had that for 3 years until upgrading to a compaq desktop with 386.

at the time compaq was kicking the crap out of IBM, they were awesome machines back then. I used an integrated desktop DOS program from Ashton/Tate called Framework II and III along with some early CAD programs. They sucked by todays standards, but you could not beat them back then. I tried windows off and on, but never really liked it. I didn't even use a mouse on my CAD stuff LOL....

In the early 90's I built my first system, a 486. Talk about kicking butt! that thing flew. I used Xwindows and could run several instantiations of DOS, each with it's own allocation of RAM... I don't recall the hard disks, but I think we were just starting to break the 1 GB barrier. I do remember thinking I would never come close to using up my 400 MB drive that I purchased for $300 at Egghead Computers in Annapolis MD..

Shortly after that Windows 3.11 came out, it took 10 diskettes to install! woah. Full 32bit OS, it actually worked!

I upgraded to a p5-66 and had my first OCing experience. all the way up to 75! it was done with jumpers back then, not easy as nothing was well documented, there was no voltage control, no memory control. You would move a jumper based on some cryptic manual, turn the system on for a second and sniff LOL..

After that I bought a boat and didnt pay a whole lot of attention to my systems, I just tinkered around a bit. I recall having an original AMD chip, a cyrix and an original celeron (talk about a overclocker!) .

At work I started buying dual xeon with scsi drives and wild-cat graphics, top of the line cad stations. No o/cing required! Again I ran NT, autocad and 3d studio.....

bought a Gateway for home with a 17" LCD and and did not touch it, I don't even remeber what chip was in it. I used that for about two years until it was stolen from my house.. There was a long pause bewteen systems as I stuck with a dell XPS laptop that I bought at work. Finally I caught the bug again and did a 145 opty at 3.0 ghz and a x24200 at 2.6 or 8.. I don't recall. Now I am on my q6600..

I used windows NT as soon as it came out I switched over to '98, installed 2000 a few times, but never liked it. I have been on XP pro for quite a while now and probably will not go to Vista until it's on SP2...

Athlon and the pencil trick/window defogger conductive paste
And every chip since the p2-300a

The mod I remember most though was the celeron 300 conversion to be able to use them in dual cpu boards.
I had to drill out a pin on the cpu and then solder a wire to the drilled out pin and attach that to another point to enable the cpu for dual support.
Most scary cpu mod I have ever done

First computer I overclocked was a powermac Blue and white G3 750 using the jumper method 350mhz>450mhz about 6 years ago. Did not do much so I upgraded it to a 1.1ghz 750GX G3 about 2 years ago

The it was a G4 with the same method to achieve 533>667mhz(with a bit more tedium), still felt like a slug though until a got a dual 1.8ghz 7447a upgrade. Now it blazes(both in performance and heat output) for a 6 year old computer.

Around 2002 I got my first PC, was a 1.4ghz Thunderbird with a K7SN so naturally no overclocking at the time. Upgraded to a Nforce 2 and 1533mhz XP 1800+ thoroughbred and overclocked it to 1900/333mhz.

Then got a XP 3200+ Barton, but the thing hit the ceiling at 2,300mhz

After than an Nforce 4 SLI board with an 64 3000+ venice @ 2,200mhz, then an X2 3800+ at 2500/250

And now as seen in the sig.

My first PC was a K7 Duron 600 MHz - I bought november 2000. Before that I had experience with PC and I had basic knowledge of what I wanted. I OCed it to 650 once just to see if it can. Then I made it back to 600 and was using it until I got my new machine and sold the old one.

My second was 2400 Celeron about 3 years ago . I started reading more about overcloking then and decided to go for Pentium 4 2.4C Northwood. That was my first major overclock.
P4 2400@3316 on Gigabyte 8IPE1000

Last year I had money to buy another PC so I went with a 2.66 Celeron@3100

Then I sold both machines but kept HDD and found my self with Athlon 1600+ Mobile integrated on an ECS KM266 based motherboard. That is the PC I am writting from now.

Currently I am going for Dual Core and will definetely OC . I want at least 3000 Mhz .
I have OCed PC for friends too:
A64 3000+ Venice @ 2400 (Box Cooling)
C2 Duo 4300@~3150 with PQI 2x1GB DDR2 800@900 P35-DS3P
C2 Duo 6400@3200 with PQI 2x1GB DDR2 800@940 P35-DS3P again
C2 Duo 2160@3000 with A-DATA 2x1GB DDR2 800@800 P35-DS3R

and for some clients since I sell pcs.

My father bought a TRS-80 back in... 1979? Something like that. It was about $1000 at the time for a 2MHz CPU and 16kb of RAM. When you turned it on, you had to go through a bunch of questions as I recall just to get to the BASIC command line. It didn't boot to a command prompt... instead you had to type a bunch of stuff... Originally it was my fathers, but when I started using it more than he did, it moved into my room. I used the TRS-80 for several years - I used to program on it in Basic and at one time I had a fairly sizeable "Zork" like text game coded up and saved to several cassettes.

But the TRS-80 was a pain to use, and the tape drive took forever. I saved up a lot of money and my parents contributed half, and I bought a Commodore 64. This was actually a pretty good computer for playing games on at the time. I still (rarely) fire up my C64 emulator and play games on it like Paradroid and Impossible Mission. I did a bunch of stuff with music and MIDI on it. I had the "portable" - think a 30lb laptop with a 5" CRT screen and no hard disk. It used a floppy drive. I used to dial onto BBS's and send email via EchoNET (think ancient internet - the kind the dinosaurs used) with my 300 baud modem. And then I remember getting a 2400 baud modem and thinking "wow. this thing is SO fast!".

Meanwhile my father upgraded to a 80286 - I'm pretty sure it had an Intel CPU but I'm not certain. He used this for several years as a business computer running Lotus 1-2-3 (old spreadsheet program). But when he upgraded to a 386, I inherited it and used it to program up games and play games. I clearly remember playing Ultima III on it.

The i386SX-25 was the first computer that I bought myself... I remember it was several hundred dollars. As I recall, it didn't have a heatsink - like no heatsink at all. As I recall, it was just a purplish/gray ceramic package... I had this computer for quite a while. It had a super fast 2400 baud modem and I used to play 'online' games like "Trade Wars" on BBS's in the Bay Area.

Then I got a DX2-66 - I can't remember if it was an IBM DX-66 (yes, IBM used to make x86-compatible CPUs), or an AMD one... I think AMD.

From the DX2-66, I upgraded to a Cyrix 5x86-100 (PR75, I think it was called). I don't want to speak ill of a design... but let's just say I had issues with it. I remember I sold it soon after I bought it and moved onto a much faster CPU.

I bought an AMD 5x86-133 and quickly overclocked it to 200MHz. This was actually a fairly rare overclock at the time. 160MHz wasn't too hard, but 200MHz took a nice cooling system and a special motherboard and memory. Of all the overclocks that I've done, I was most proud of this one. It was fast, it was reliable, it rocked.

Then I got a job with Intel. And suddenly my pride in my 66MHz (50%) overclock didn't seem like such a great thing to talk about with my new Intel co-workers. Soon enough, I sold the computer (I even wrote that it was overclocked in the advertisement in the San Jose Mercury News) and upgraded to a Pentium. At Intel I worked on the design of the 200MHz Pentium and I got a free CPU at the end, and then a Pentium w/ MMX soon after that.

Then I bought a Celeron 300A and overclocked it to 450MHz and I used this for a while until I worked on the design of the Pentium II - which I bought soon after (no Intel freebie for me on this one).

Then I bought the last CPU that I ever used for a while overclocked - an Intel Pentium III 550MHz which overclocked comfortably to 733MHz.

Then our daughter was born, I'd had some digital photos... and I had a bad hard disk crash. I didn't have much in the way of backups. it was not good. And that was the end of my overclocking. Overclocking had nothing to do with the hard disk problem that I had... at least I don't think so.. but the risk/reward equation shifted when I started having my taxes, my finances, all of our children's photos and videos, my band's recorded music, my entire CD collection, etc. didn't seem quite as compelling as when I didn't have a lot of money and all I had on my computer was video games. Now with all the stuff on my computer, I don't overclock. If the CPU is slow, I just upgrade. But I just want the computer to work 100% reliably 100% of the time. It's probably a sign of old age, but I just don't want to mess with it. And I backup like a crazy person.

First overclocks i remember doing were on old 286 machines.
They didn't have programable clock gen chips, you had to change the crystals.

This normally didn't involve soldering as they were generally fitted into sockets.
There were 2 types electrically the same but different physically, both had 4 pins.
The Square ones each side about 10mm, and the rectangular ones twice as long.

Anyway all you had to do was find one with a higher frequency and swap em out.
I did a lot of 16mhz to 25mhz overclocks that way.
Also did a few 386 and 486 overclocks by changing the osscilators.

486 SX25 to 33 Overclock was very popular, sometimes because the end user did it themselves or more frequently the shady PC retailers flogging 25mhz chips as 33's.
They used to glue a Heatsink on the chip so you couldn't tell what it really was.
Early 486 boards still used the plug in crystals.
Had a SX25 myself for a while, could never get it to run at 40mhz properly, 33mhz was easy though.

Most noteable pre Pentium overclock i did was an AMD 486 DX4 133 to 160 overclock.
Used that as a game box for at least a year whilst the price of Pentiums came down.
That had VLB [Vesa Local Bus].
If memory serves it had a Western Digital Paradise Video card and a Promise Caching IDE Controller, both VLB.
8MB RAM on the MB all one MB simms, 4MB on the Promise.

Had fun with a pair of Celeron 300a's in a BP6 running at 450mhz, 50% overclock and SMP with budget chips.
This was my first home Server


End of part one.

Um...this was your 3rd post since 9/06...you've had PLENTY of time to OC.
