o/c-ing a p3 733?

[spazzkid]

is it possible to oc a p3 733? has anybody tried to oc on a soyo motherboard?

thanks

Hi spazzkid, welcome to the Forum,
Yes, you can OverClock this chip, but you need of mem module that can handle freq. of 150-160Mhz and a good cooling section, especially the Cpu cooler (forget Thermaltake's!, aren't good for the OC think).
About your Mobo, all depends by the model.

I hope it helps you ;)

jeez, im just using generic mem modules... u kno the el'cheapo taiwan brands... branded mem is expensieve... my mobo is a soyo 7vba133 with o/c features in it... im quite afraid to tinker with it... have u had experiences with a soyo mobo running a p3 cpu? :)

I've no experience with that motherboard, but you should do some research and see if the memory bus has a divider. If so, you'll be ok. Even if not, you can probably still overclock a little. Try bumping up the FSB just one notch and see what happens. I'll bet if you go up to about 135 or 137 or something like that, you find that your system will be overclocked! See how easy that was, wow. Now is the time to start thinking about cooling. Overclocking produces a lot of heat which can make the system unstable. A tiny bit of overclocking probably won't raise temps up too much, but before you start getting carried away, you'll have to deal with cooling issues. Good luck.

hey thanx for the advice batboy, here in the philippines its hard to find pc parts... most of them sell oem and branded pc's... most of the people here dont give a **** about pc parts anyway... i just came back from work... i dropped by a computer store to find coolers for my p3... wut do u suggest... i read the reviews on the internet... its hard to decide which is the best (btw, i use a socket 370)... all those reviews are making me dizzy... is global win a good choice? howbout Thermaltakes? Anyway, thanks again for the advice... i really appreciated it dude... this o/c forum is quite kool... people here DO REALLY HELP each other... peace out

Hi spazzkid,
Better to go with a GlobalWin Cooler than a Thermaltake!
the Fop38 is a good way to go, but is really noisy with the Delta38 fan, a possible solution is to replace it with an 80mm High performance fan.

[outhouse]

There's allot of usefull info here in the tips section CPU database ect. ect. as well as the forum if your still have any questions hang out a while before you make any quick judgements get a good background and you will do just fine, theres allot to learn [if you want to be a overclocking artist] and we would be glad to lend a hand. Welcome to the forums.

[batboy]

The GlobalWin FOP is a real good cooler. That's what I'm using right now. There are better coolers on the market, but for the price, you can't go wrong with the FOP. Like what was mentioned, the Delta fan is too noisy, so I clipped a 80mm fan onto it instead of the 60mm one. Larger fans tend to flow more air and are quieter. I overclock my P-III 700 at 1050 all the time and my CPU load temps stay ay 40 degrees or lower. Don't forget to use some good thermal paste too and maybe think about an extra case fan or two. You'll be good to go.

ey batboy,
thanx for the advice... i try to look if pc shops here sell FOP's. I've got a question... my mobo has memory settings that has selections of "slow, medium, fast, turbo"... would setting it to turbo make a difference? by the way, im using 2 generic mem modules one is a 64mb another is a 128... do u think it would perform good? another thing... wut does host/pci clock mean? Thanx a mucho

correct me if im wrong, but can a celery 800 o/c to 1++ gig by just setting FSB to 133? im planning on buyng a celery instead and exchange if for my p3 733... wut do u guys think? another thing, when changing processors, is it necessary that i reformat my HD?

thankies

Hi spazzkid,
The best mem setting to go at the rated speed of 133Mhz is the 'Turbo' mode with your mem module, but not if you're rising the Fsb, better to go with more conservative settings.
About the host/pci clock are the Fsb/Pci freq. that are linked: with a Fsb of 66, 100 or 133Mhz the Pci freq. is 33Mhz coz the divider switch on 1/2, 1/3 or 1/4 of the Fsb, but not with all the others Fsb, that generates higher Pci freq. that can gives prob with the Pci/Agp cards and also to the Hd's with possible fat corruption!!!

Yes, it's true, but you must also consider that your P/// 733Mhz is more powerful than a Cellie for the double cache, and the performance of your chip not OCed and a Celeron 800 OCed@1066Mhz are really close!

[spazzkid]

the doors,
i cant understand, if im planning to raise my FSB (thru pci/host clock selection in my bios) that could give me HD and video problems?

about celly800, so an oc'd celly running 1++gig just runs fast as my p3 733? so what are my upgrade options then? im planning to go amd but it wud cost me a new mobo and processor... i need to make use of my present mobo for cost saving reasons.

oh, and one more thing... if i change processors, would that i mean i have to re-install my whole system as well?

:(

spazzkid, I had this processor before my 866. It does have a little room to OC, but the low multiplier is the main limiting factor, I think. Before I switched, I was running at 935 (5.5 x 170). This puts the PCI/AGP buses way out of spec, though. And yes, it can cause HD/vid problems, but I never had any. I was also able to cycle through Windows (just in and out) at 180 FSB, and POST at just over 1 GHz. All this required a higher voltage, too, which can fry a processor.

Your upgrade options are still not bad. On a 133 bus there is up to 1.0, and on a 100 bus there is up to 1.1 (my next toy).

And as far as I know, you wouldn't have to reinstall anything just with a processor change... unless you break something. :)

I'm not saying that you'll got probs, but you must consider that using a Fsb of 140 or 150Mhz the Pci freq. is 35 or 37.5Mhz, both out of the spec (33Mhz), and some Pci/Agp cards or older Hd's can have probs to handle this freq.
About the Cellie 800@1066Mhz, for sure your P/// 733Mhz is more stronger, infact a P/// generally is 150-200 more faster than a Cellie, so it's very difficult to say what's the best upgrade to go, for sure to OC any P/// with a Fsb of 133Mhz are needed mem modules Pc150 or Pc166 (like Tonicom,Crucial, Mushkin, Kingmax) and a Mobo with Voltage adjustment.

[spazzkid]

for your reference... here's my complete spec:
p/// 733
soyo sy-7vba133 (unheard of? check out http://www.soyo.com.tw )
generic192mb pc133 (64+128)
innovision tnt m64 (oc'd 152/150)
western digital ata66 5400 15 gig
generic cd rom
sb live! value
c-net lan card
generic 56k int. modem

do you think my spec couldnt handle 140++ fsb?

for my upgrade options, wut do u think is the best intel processor which saves cost, runs faster than a p/// 733, and highly overclockable?

I don't know how your system would work. I'm simply a hobbyist overclocker. I can tell you that my problems have come from the RAM (have some CAS2 PC150 on the way) and my previous NIC (Kingston). I've also noticed that my 866 can run higher at default voltage than the 733 did. I'm assuming this is due to being cD0 vs. cB0 step.

I just thought of some processors that a lot of people seem to get a high OC out of: P3 700 and 750. It's a 100 FSB chip. There are several people here that get over a gig out of them. And they're probably less expensive than the 733 you have now. Check around here and see how others are doing with it.

Well, without a test it's very difficult to say if your system can handle or not 140Mhz of Fsb, but for sure the bottleneck are your generic mems module. First of all check your system temps with MotherBoardMonitor that you can found at http://mbm.livewiredev.com/ and if your chip temp never go over 40-45 degree C @full load (100% load) try to rise the Fsb into the Bios and also a little the VCore (Cpu voltage) if unstable, but not over the 15% of the rated voltage. I suppose that you found this settings directly into the Bios.
