celeron 633 and asus cuv4x

[parot50]

im new to overclocking an have my settings in the bios set to cpu:system multiple9.5x , system/pci freq - 80 and cpu vcore -1.65 . my system info shows 759 now and i have 320mb ram .are these good settings for my combo ? the temp of cpu seems around 34 on avg . thanks

[vlovich]

First of all, looking at your Bios temp is useless because your CPU is under the least load. Try downloading something like CPUCool and running something like UD agent which causes a 100% load on your processor (what you get in games) and monitor the temp in CPUCool. Furthermore, I also have a Celleron 633 and was able to get 1Ghz (9.5x * 105mhz FSB). I wasn't able to go higher for some reason (probably not enough voltage. However, I use a voltage of 1.79. You might not be able to get it higher. But I'm pretty sure you could at least set the FSB to 83mhz.

[parot50]

at 100% load my cpu temp goes to mid to high 40,s . whats the max safe temp for the cpu ?

[batboy]

Your CPU will handle mid to upper 40's load temps, but the more you try to overclock it, the more it will probably be unstable. Certainly do not raise the voltage up any higher until you get better cooling. With an extra case fan or two, a good CPU cooler and good themal paste, those Celly 633 CPUs will often do 950 MHz. At those speeds, you should shoot for max load temps in the low 40's at most. The cooler you run, the more stable you'll be and the higher you can overclock.

Hi parot50, welcome to the Forum,
You have a good Overclocker, infact the Cellie 633Mhz works with a good cooling section (HeatSink, thermal paste & case cooling) @100Mhz of Fsb (950Mhz).
Heat is your enemy, so it's better to have a Cpu temp @full load not above 40-45 degree C, but less is better, I suggest to use the program called MotherBoardMonitor, the best, to take full control of Temps, Voltages and Rpm's fan (take a look here (http://mbm.livewiredev.com/)).
So if the temps are right, you can set the Fsb@100Mhz, much better for all the peripherals, especially Hd's & Vid cards, coz the Pci/Agp bus will be in the specs, @33Mhz, and if the system is not stable, rise a little the VCore (Cpu voltage) too, but not above the 10-15% of the standard voltage, generally 1.8-1.85v are enough.

I hope it helps you ;)

[parot50]

thanks for the help ! will leaving the side cover off the case give any cooling help ?

[batboy]

Yes, leaving the side panel off often helps heat from building up, but it still don't help the CPU a lot under load conditions (like playing intense 3D games). That's where a good CPU cooler comes in handy. At the very least, use a good thermal paste on the heatsink instead of that crappy heat tape most of the factory retail coolers come with. That should help lower temps at least 2-3 degrees or more.

[SwedeDude]

I never had a Celeron 633 but i had a 600.

I run it at 2.05 voltage and 1018Mhz in 2 years without any problem.

Cooled it with a Fop 32-1 that had a 92mm Papst on it. No case fans at all.

But i don't think that is something to recomend! <--Dont know the spelling:)

[parot50]

tried going to 100 fsb , xp wouldnt load , raised voltage to 1.8 ,xp loaded and locked causing errors on my harddrive . i think ill stay at 80 fsb as its very stable there , but what effect will that have on my harddrive and video card ? thanks

Whats the cooling like?

The air flow like?

Don't raise the voltage when you dont know your temperatures it will be dangerous for the chip.



That chip will most likely hit 1gig and your only 1/3 there.
You'll need better cooling. Your video card and hard drive will have no effect. The only effect hard drives get is when the PCI spec is 41+ since it runs on PCI bus and it will most likely cause data corruption.

[parot50]

any recomendations for a heatsink fan combo for celeron 633 and asus cuv4x . and where to order on line in canada ? thanks for all the help .ps id want to use the original clips for mounting .

thanks

Please, what is the Cpu temp @full load (100% load)?
this can be the prob (heat), or it want an higher voltage, do you have tried with 1.85v?

P.S. Using a Fsb of 80Mhz is less safe than 100Mhz, coz the Pci bus will be at 40Mhz (1/2 of the Fsb freq.), very far from the specs of 33Mhz, and that can bring possible probs with all the peripherals that uses this Bus, especially HD's, with possible Fat corruption and loss of Data, and the Agp bus will be at 80Mhz (the Fsb freq.) instead of 66Mhz, and not all the Vid card can handle this freq. so cannot work at all or properly and for sure will be overheated. Going with a Fsb@100Mhz it's much better coz the Pci Bus will be 1/3 of the Fsb freq. (33Mhz) and the Agp bus will be 2/3 of the Fsb freq. (66Mhz), but I don't know if on your Mobo the dividers are automatically setted or you have to set jumpers, or set parameter into the Bios, so take a look to the Mobo user manual for more infos.

I hope it helps you ;)

[parot50]

i managed to get it to 100 fsb with the voltage u recomended but my load temp goes into the mid 50's .is that ok ? and idles around 30 .

[The Doors]

Plz, what kind of HeatSink & thermal paste are you using?

[parot50]

intel heatsink and fan with thermal paste . p.s ive ordered a Thermaltake Volcano 7 .will this be a good investment for me and will it clip right on to my setup ? thanks again

[The Doors]

Well, you need for sure of an high performance HeatSink for your Cellie, you can consider a quiet & very cool Millenium Glaciator II & Artic Silver II, take a look here (http://www.millennium-thermal.com/start.htm) for more detail ;)

[parot50]

ive ordered a Thermaltake Volcano 7. will this be a good investment for me and will it clip right on to my setup ? thanks again

[The Doors]

You're welcome parot50 ;) it's a pleasure,
I'm not experienced with this cooler, but it seems to be a good product, and it's compatible with your Mobo/Cpu, personally I'll go with a Glaciator II coz totally made of copper, is on the top.

[The Doors]

Wait a moment,
I'm not yet sure about the compatibility with your Mobo after a more deep look at the Volcano 7, all depends by the room available around your Mobo Socket!

[batboy]

If your load temps were getting into the 50's, then that's waaaay too high. That cooler you ordered will be much better than the factory heatsink. Don't forget to use a good thermal paste too. I think once you get a little better cooling, you're going to be fine.

[parot50]

which is more acurate motherboard moniter or asus probe 2 ? theres a big difference in reported temperatures !

[William]

MBM5 should be more accurate. Asus Probe reads around 5-10C too high.

[parot50]

actually mbm is reading higher in my case 5- 10 ! weird

[Yodums]

Try setting the temperatures using all sensors and you can post all your temps and we'll help you identify which is which.

Volcano 7 should fit your motherboard since it is 80x80 not the regular modern 60x60 like others.

The Volcano 7 is good although what you need to do is mod it to run it at 5000 rpm, since it won't run the direct 5000rpm until you mod it.

Heres my suggestion.

Turn it back to default speeds, turn the voltage up to 1.7-1.75

Download Seti or CPUBurn and burn-in your computer till you get the new cooler since what your running at now is sort of dangerous.

[parot50]

how do you mod the fan ?

There's a probe sort of on there.

You snip the wire of the probe and simple strip it so it shows some skin and connect them and you can finish it with electrical tape.

[parot50]

thanks for the help ! ill take your advice !! what does the burn in program do ?(sorry for all the questions)

[parot50]

i got my new heatsink and fan and am now running stable and cool at 950 . but in the memory benchmarks i score very poor . i have 320 mb pci 133 ram how could i set it up to get the most out of it ? thanks

[The Doors]

First of all I suggest you to check the stability of the 3D section with 3DMark2001, and for the Mobo/Cpu programs like Stability Test, Prime95, Folding@home or Seti@home.
About the poor memory scores, they can depends by the Chipset (your Mobo essentially) or by the mem settings into the Bios like Ras & Cas delay setted on 3 (conservative) instead of 2 (faster)that brings better results, but you can compare the scores only with similar Mobo, coz the other are really faster, especially with DDR mem mudules!

We hope to have got another satisfied OCer! :burn:

P.S. what are the Cpu temps @950Mhz @full load now?
curious about the Volcano7 cooling performance :)
