p4 1.8 SL6SN 4054 Mhz ( fsb 225 )
abit IC7
2*256 Mo DDR Adata BH-5
radeon 9800 SE hercules@ pro
the max stable I get is 3672@1.82V ( rock stable )
3DM 2001 : 22383
aquamark 3 :55300
radeon 9800SE@pro 460/370
cooling :
dangerden MAZE 4
eheim 1250
maze 3 GPU
I think , the previous record is the jelen's one
Get Phase Change Cooling or borrow a Cascade, want to see that baby reach more :D
Awesome Oc !
Very impressive OC...
Those pentiums are coming out of their shelf lately :)
Nice 1.8a you have there :toast:
I've been looking for a 1.6a northwood as i think some were produced for OEM's but it's likely i won't find one for another year or two in some dell or other OEM box.
Anyway, what's that chip there? Is it OEM/Retail?
If it's retail what was the pack date?
I played with a watercooled 2.26bsee here (retail June2004 pack date) one last time on Christmas day (10f ambient) and got it upto 4400MHz. It was only Pi stable to 4333 but the video would not clock up at all as the PSU was falling on it's face so did'nt spend alot of time running over 4300MHz as i thought i was pressing my luck with the PSU.
If you got a way to get it cold go for it!
That Northwood P4 A is going to die soon at 1.888V, that's for sure.
But it is a very nice OC, very nice indeed.
1.6 were also send in box ( I had one long time ago )
well played with your 2.26, it's a better oc than many prescott :D
I 'll try to put my cpu under misterroadster's cooling system , soon
I
How about some screenies with the current version of CPUZ, 1.26 would be nice...
Get it here http://www.cpuid.com/download/cpu-z-126.zip
what will be the difference with my 1.25 ? :confused:Quote:

But if there's a good reason to move to 1.26 I 'll do it
:slobber: awsome p4, get a vapo ls or mach2gt:D
I would love to see what you can do with it under the cold. You have to love Intel sending these nice Northwoods out as thier inexpensive chips.Quote:

1.26 is the only CPU-Z version that is supported for varifying a clock rate. It can be done on the older versions but it sounds like its easier to cheat or something. Not saying your cheating but I believe he's just trying to check out your clock rate.Quote:

wow, amazing clock...
whoever sold it must sure feel bad about it now ^^
the last owner reach 3.55Ghz using stock HSF :slobber: , 3.3Ghz with stock HSF and default vcore
Does anyone know the overclocking record ( in % ) ?
theres a guy named rio71 iirc, ask him, hes totally into %tage ocs of mobile P4's and old 100fsb P4s :D
im sure he knows... if you contact him send him greetings from me :D
a guy here in sweden did 168% with a 1.4ghz celeron mobile i think :P
you know if its true that you reached a certain clock speed, dont risk damaging your hardware to please some sceptic.Quote:

no disrespect intended, just i've killed hardware myself and don't want to see another person go the same way.
Your post makes my point quite well.... the age of his processor has absolutely nothing to do with CPUZ, and IT IS NOT acceptable for a verified overclock. The Checksum is 100% useless on any version of CPUZ other then the latest, contact the author if you don't believe me. CPUZ frequency display can be faked 100% with a small rather well known program, which is a free download. The checksum will appear 100% authentic. The new version of CPUZ is not effected by this. Hence the request for a verifiable OC... He can do what he wants, but a verified Clock is a bit better then one that leaves qustion...Quote:

I think it's less dangerous than trying to bench using this vcore
snowman99 > 168 % :slobber: It will be hard to beat
karnivore > see the attachment ;)
thank you very much Flo :toast:
Now I won't get a bunch of PM's asking to verify your screenshot, and then have to explain why I cannot do so.
http://www.xtremesystems.org/forums/...id=23466&stc=1
no problems
I was sure that you was able to verify a screen shot with 1.25
i just think its a bit silly that people demand all these different versions of software, doesn't it look a little pesimistic? looks as if no-one trusts anybody, which in itself is poor, attitude wise towards others.
anywayz i'm off, articles to write.
hope you get your hands on some more nice chips flo :toast:
the numbers on the left bottom corner aren't the same beetwen 1.25 and 1.26 :DQuote:

Was no demand, but having delt with a pretty high number of recent Fakes, makes it a necessary evil, and a common request here.. Has nothing to do with poor attitude. I also see it was a rather painless thing for FLO to do, which didn't seem to trouble him to much. No one ever demanded anything, I made a polite and simple request. Had he been unable, or unwilling to use the current version of CPUZ, that would have been the end of it. Perhaps I may have posted a remark stating that we could not verify his clock speeds, but most likely would not have.Quote:

Good job :D
Once I had P4 1.6Ghz Northwood. Pushed it to 2.7Ghz on air :)
Let them work hard :D
sick, sick, sick...... very Xtreme OC
C
Wicked. Way high!! Get a phase change. We gotta see what happens.
thanks flo850 and that is some awesome overclocking
is phase change a possibility for you?
if not put your rad outside with some more 120mm fans!
and i thought my 1.8a (socket 423thou) at 2.7Ghz was something very special :toast:
There is no such thing as a 1.8A on socket 423.
it's a socket 478
according to intel website , p4 1.8 socket 423 exists , but I guess there are reserved to oem
ooops my bad! meant to say 1.8 ;) which came from a dell desktop !
omg that is one awsome o/c, wat r the stock fsb on those cpu's?
the stock fsb is 100Mhz
I've got a 2.4 533 here, it overclocks on default voltage to 3.2 without a hickup.
only, one mhz more and I've got a reboot, even on higher voltage.
stupid mobo I guess.
very nice my myself now thinks my pittly 3.6GHz on air needs a work out thats stock air and 1.65 Vcore btw, ill wind up getting some new ram seeing how i blew up my PDP and the GSKILL is being put to work in the a64, might be able to give ya a run for your money :p: very sick overclock tho very sick
I'm sure you can reach 4Ghz with watercooling
P4 A are not dead :D
my max stable is 3.67 Ghz with 1.82V , 3.6 with 1.72 V , so your cpu seems to be able to reach more hich clocks than mine
flo850
Well, they are sort of dead. Your 3dmark score shows that ;)
that's right : my cpu can't outperform an overclocked A64 , or a high end prescott
but when it's overl:banana::banana::banana::banana:ed , it gives me enough power to play recent game in a decent resolution
At stock frequency , I can't
Your trust kinda crumbles once you've seen fake screenies posted.
Once bitten and all that.
so wheres the cpu-z 1.26 shot? :P
here it isQuote:

Karnivore had every right to ask for a 1,26 shot. When i first saw the :banana::banana::banana::banana:, my first response was fake, but obviously (thankfully ;)) I was mistaken.
Very crazy OC. A bit like the Celeron D 2,5 reaching 4ghz on water :)
thats one nice clock off a P4a..nice job^
Congrats!
125.27% oc
:toast:
Im sure if i got a XP-90 and some BH-5 i think ill be able to hit 4GHz my board offers 3.3v to the ram thanks to older BIOS :)i have to RMA my PDP and i think ill sell it and get some BH-5 see what i get thanks for the complement but i wont know till i try lol
no need of BH5 to reach fsb 200
you can use 1:1 ratio , if you don't want to be limited by your memory
Very very good this CPU :)
for some reason i cant seem to set a divider on my MSI board so i cant : / but im sure if i get some BH-5 i wont have probs :)
very nice p4 1.8A.. :)
I have same, we probably bought it at the same guy in france... :D (steph hfr..)
mine is just running @2.6 with 1.525 in barbone with stock cooling :)
confuzzedintel > on my IC7 I can set the "cpu strap" , so I can make my mobo believe my cpu is a fsb 800 one
evilrules > that's right ;).
wow, really nice cpu!
i think the p4a are really good cpus. my p4a 2600mhz runs stable @ 26x133; 1,525V and a crappy barebone cooler. really like to see my cpu under wc or phase-change! only one thing is bad about them. they dont have HT! :(
my p4a 2.0 (100x20) does about 2.7ghz on air stock volts, my crappy mobo is limiting my oc!!! what P4 mobo could anyone recommend me for under $50?
abit IS7 : vcore up to 1.975V , vddr up to 2.8V , i86Pe ( dual DDR + 2 x SATA )
i'm sure you can find it for less than 50€
nice clock :toast:
isn't this the WR for P4 A CPU's?
incredible OC :slobber:
:slobber: Really nice OC. :eek:
amazing! have pics of it? did you try other cpus? how well did they clock?
very nice! :toast:
that's only a watercooled system , nothing impressive
I don't think it's a WR for P4 A ( in % ) , I ' ve seen a 1.6 @ 3.75 Ghz
I 'll try to put in a more extrem cooling system , to break records
