Hi everybody,

I recently bought an Asus P4B533-V mobo (i845G) with a
Pentium 4 1.8A Box version. I've also a Samsung stick 256 Mb
DDR 2100 and I will buy a GeForce 4 Ti later. I intend to keep
my hardware for probably 2 years or more and I'm interested by
the overclocking.

I can read many Tips and tricks which tell it's possible to increase
the frequency of the P4 1.8A and the FSB. e.g: Something like 1.8
to approx. 2.26Ghz with an FSB at 533Mhz. Lots of users seem to
have made this test and so to obtain interesting scores of speed...
I checked the core of my processor: It's a SL63X which could be
overclocked too. But, what is the REAL stability and life durability
of an overclocked system? I must say that if I take the decision
to overclock my processor this will be for all the rest of the time.
I will run all softwares with the overclocked state. That's why, to
avoid making a bad parameter setting of my machine, I prefer to
ask to users who could testify of this sort of experience.

So, if you have a good experience with overcloked P4, your
answers are welllllcome!! (many thanks in advance! :))

Here are my questions. Sorry if they can seem a little bit IDIOT,
but I want to know...
In case of an overclocked from 1.8 to 2.26Ghz,

- What could be really the cruise temperature of my processor
after, e.g, 8 hours of intensive use with AutoCAD or games?

- Do you think this temperature could be comparable to a true
P4 2.26 for the same use? or more?

- Is it necessary to replace the original Intel fan by an other?
(Cruise temperature of my 1.8Ghz processor is 37°C (98.6°F)
with open case and 30°C for the room)

- According to your experience, do you have encountered any
system freezes while you play games or softwares using a lot
of processor ressources? (Freezes which we could not impute
to drivres problems)

- Do you think that there is a risk of breakdown on the long term:
For the processor? For the mobo? mad:

- Imagine that, finally, the system works correctly (yep!). Then,
do you think that the overclocked processor could have a life
cycle comparable to the one who is foreseen for 1.8Ghz?
( It's the BIG question! :eek: )

seen other ppl o/c and still have not seen anyone with any o/c problems with the 1.8a

I suppose the 1,8a and 1.6a is the best chip ever produced for o/c

hi, and welcome to the forums.

with the cpu that you have I'll bet you can safely run at 133fsb...most likely at default voltage (1.5v).

this will give you a 2.4ghz cpu.

as long as your cpu temps at full lode are not higher then 50c...true reading, then you will be fairly safe at running it long term.

when OCing, there is always a risk...yet your 1.8a should last at this speed for more then two years.

since it could get hot at times in your room...I would get a new heatsink and quiet fan (just for procaution).

may I sugjest an AX-478...

it is easy to install/uninstall
it's cheap
and it works just as well as the new swiftec and alpha.

the sunnon50,panaflows,and ystech make great quiet fans that will be just what you need.
I'm using a $6.00 ystech fan, and I'm very happy with the results.

don't forget case cooling...two to four case fans should be more then you need, yet with out it you will have diffeculty retaining low temps.
they could also be quiet fans.

dont forget AS3.

the only thing that might hold you back is your memory.
pc2700 DDR is what you might need,yet see what you can do.

good luck

Interesting to mention 'real' temperature...
I have OC my PIV 1.8A@2.53 with the original Intel heatsink... I was planning to keep a good 2.4 for safety, but, you know...
At present I'm running with a 52 - 54°C, but benchmarking brings CPU temp. up to 70 C...
I'm a little bit surprised by people mentioning temps as low as 40°C, while I get more than 50 just when I start my computer, even at 1.8GHz...
Is it possible that the probe is not correctly calibrated, and how can I check and put an offset??

Thanks for any answer!!

wow, reading posts as far back as Aug. are we....

hey, wecome to the forums.

anyway, what mobo are you using???
and what are your room temps like???

your temps do seem high...so good case cooling and maybe a better HSF should help.

we need more info.

Mine is great at 2.4, most people can get 133fsb no problem, I"m using stock HSF, and basically my non-overclocked cpu and overclocked cpu has temp diff. of 2 to 3C and that's it... so I would think it's good. Stability wise, I don't think processor has caused my cpu to crash, it happens sometimes when applications get wierd, and XP gives way..

My material is:
Mobo ABIT BD7 Raid
256Mo PC2100
HDD ATA133 80Go
GeForce 2MX
integrated sound AC97...
and by the way, I have trouble getting sound when I go over 33 MHz for PCI... Hopefully, the Abit allows to set frequency to fixed values: I can only get sound when it stays @ 33... Is there no other means to solve it than by adding a separate sound card?

Well, room temperature is around 20 these days... I just added a 80 mm fan at the rear of the case, but maybe I should check what the proc-heatsink contact surface look like, and add some arctic silver paste or equivalent?? I heard that the 'black chewing-gum' they put in standard is not so good...

Sorry if these questions are evident for you guys, but I'm new there!!
Many thanx for your help!

a Geforce4mx will probably cost only a little more than a geforce2mx, so that might be worse it. And if it isn't at the moment it sure as hell would be when NV30 comes out next quarter. Go BD7 II RAID cause it's newer, and it has fixed pci and stuff... IT's a great board. If you're going to get the ATA133, that's probably a maxtor, so I'd say go for the WD 80G with 8MB cache, that only costs 20 dollars more, and it's faster...

Btw get some Arctic silver 3s and scrape off the orginal thermal paste with a razor. Make sure you don't damage the heat sink though. And PC2100 wouldn't give you very good yields ur cpu does OC like crazy, so PC2700 should be considered for an extra 15 dollars
