Highest %-overclock?

[HMB]

Hi!
Im wondering what your overclocking records are in percent. What processors/mobos etc were u using?

My record:
Duron 600@1521MHz vcore 2,75V
Mobo: Abit KT7A V-modded
Ram: Twinmos pc-166
Powersupply: 2x300W serverPSU + enermax 431W which were hooked up to the mobo with y-connector
Cooling: LN2

This was done last year for the swedish overclocking championship which me and a friend won. Gonna compete this year also and im interested in what a celeron 266/566 would do.

Edit: I might add that the CPU died when we crossed 3V. The cpu did 1000MHz stable on air with a fop32-1. Around 1200MHz with watercooling.

dunno dude.. but u are famous atleast
fooking nice vcore

Vitalizer: Hehe, thanx.

1700+

1466 to 3114 MHz in a -50C prom

[Evil_Spork]

crazy!

[Dr.Demonic69]

My 1700xp does 2.5ghz prime stable so thats over 1ghz oc on air. Simply impressive.

There are some 2.4's here that do 4300+ but its not near the same overclock % wise as that 600 @ 1500....

Yeah the competition is %-wise thats why im especially interested in a celeron 566 or duron 600. With a good mobo id reckon 200% with the 566 is feasible. Btw, what are the lowest speed of the durons? I think i remember there being some duron 550:s for a while. Now one of those would be a killer i think.

Celeron 300s at 750 are pretty impressive too.

Yes, hmm, a celeron 266 which has no L2-cache and lower speed than the celeron 300 should be able to get higher. Only problem is that its hard to get celeron 266:s. But 300A:s shouldnt be a problem. Another problem though is to get a good mobo with a 1/5 or 1/6 divider. 50MHz on pci isnt very tempting :/

[X-Ecutioner]

there`s a thread around here where some guys oced a 100->247

147% ...

i lost the link sry...

mine is 1600->2420(2440 but not stable enough(water 1.85v)

im currently tryin to oc old cpu`s ... 266->333
333->412

the prob is i dont have any info about the mobos and just tryed some jumper settings... i hope ill find away to vmod a old 333 or 400 celeron ... but my 9500np is more important atm ... need watercooling (maybe pelt) and vmods... got the stuff for vmod but no coolin yet...(won`t vmod untill watercooling)

Highest I had my old Celeron 366 is 595 @ 2.2v on air.. heh 8-)

I've got a cache-less 266 around somewhere.. gonna take a while to dig it up, though... and my Abit BE6-II is dead 8-(

[saaya]

wheres the link to this 4x86 (25mhz) @ 600mhz? that was even without ln2 or dryice, just some simple phase change

[sjohnson]

Dual Cel 366, Abit BP6 at 5.5X125 @ 2.2v, stable for everyday use. Never was able to get them to run 100% O/C though.

For a very short time i had one of the fastest duallies around

Sweet I remember the celeron 300@464 days. Damn that cpu was good, spanked the p2 450 at the time.

[Peen]

u should get like a 133mhz Pentium with MMX , i had that at 200mhz on air for a lil

[saaya]

well this all doesnt get close to this 4x86 oc somebody posted a few days ago, at least not percentage wise...

[saaya]

33mhz@247mhz thats a 748% oc

http://totl.net/Eunuch/Eunuch2.html

a 750% oc on a 1700+ would mean 11ghz...

[Kunaak]

JC old CPU that he got to 3.1 ghz...

3.2 (14x230) under dry ice.
I have no idea of the percentage.

1.47 to 3.2 ghz= what?

[sjohnson]

3.2/1.47 X 100 == 218% (rounded) - a 118% overclock

[Tedinde]

1.6a P4 195fsb on a abit TH7II RDRAM board 95% OC.

hi,
i win the overclocking championship in hannover/germany.
more pics and info here on my page
i clocked a mobile celeron northwood to 100%, this was enough to win.
- epox 4gea ; i845GE
- 300w psu ; hec300 lr-pt
- corsair xms 3500C2 ; running only ddr400
- modded box-cooler from 3.06 (thermistor removing, lapping...)
- celi has no ihs, add a plate under the socket to hold the board flat for good hs-contact.
- vcore at 1,65v
- the rig running all days seti with this speed.
- ... nothing special

my epox 4pea800 made a cleaner vcore an i can run the chip up to 100mhz faster (3100mhz).

50MHz PCI is possible, my Barracuda IV can do it at ata100 , if the hd don't like highfsb you can allways lower to ata33 or pio-4 should help some.
But finding a mobo, memory that can do 200MHz FSB? That's harder and can a old mobo do that without turboPLL?

Much be hard finding both Duron 600 or celeron 300 though and a good slot 1 board that gotta be hard to find. How do you plan to do that? I dont think blocket is gonna help

Good luck.

Nice celeron overclock, 100% on air is pretty impressive.

i like this one, cuz not only is he getting a 95% oc, also getting the 95% performanfce. Dont get me wrong that 100% oc of celery is nice,actually very nice, but its still just a celery!

[Rio71]

but its still just a celery

but this mobile has 256kb L2 cache.
@ 3100mhz need 2:30 for a seti bench-wu (angle 0.416) here my list
the performance ist not really bad, the desktop cely with 128kb need much longer
i have a second c4m running 2000 @ 3300. im looking for an i865/i875 board but no luck yet.
when it all together, i made some benchis... sure with "aha"-effect.
