Overclocking Celeron 600 on DELL XPS R systems

[n64spelaren]

Anyone who knows how to overclock a celeron 600 (or 633 or 667) to 900Mhz on DELL XPS R systems?
Exactly how do I do the overclocking?
You know a good site that explains this good or you can tell me about it now?

Does other computer components get affected if I overclock?

Dell, among most of the other "name brand" computer manufacturers go to great lengths to prevent their machines from being overclocked. They don't want you buying the cheap model, and turning it into the expensive model. They neuter the bios and remove the jumpers that would be used to overclock.

I have a Dell Dimension XPS R400, if you want to overclock your system, buy a iWill Slocket II Socket 370 to SLOT1 adapter, I think i heard it at the Dell Forum that it is the best slocket for this computer. Buy a Celeron 600Mhz with cC0 stepping, or try to get one since it's the best for overclocking. The label on the side of the processor box should say 1.7v on it, indicating it's a cC0 chip. Put the new chip on your slocket and set the slocket jumpers to 100Mhz Bus, Coppermine, and probably leave the Voltage setting at AUTO or 1.7v (if you have a cC0 chip) With these settings, it should take you to 900Mhz. Take out your old PII processor and put your new Celeron with the Slocket in, and there should be a place to plug the fan for your cpu near the SLOT1 slot. Then turn on your computer and have your fingers crossed... if it doesn't boot or start, take out the slocket and increase the voltage up by increments of .1 volts until it boots and runs windows stabily, just don't go pass 2.0v since 2.1v is the max intel rates for this chip, and you might have a chance of frying your chip. Remember, higher the voltage or vcore, higher your temp will go, so have proper cooling and good luck... Yea i know, im bad at explaining things..

I have exatly the same system ,XPS R400. You explained it very godd, thanks. But still have som questions.
1. Will it be easier to overclock a celeron 633 or 667 to 900 (or higher than that)?
2.Should I buy a boxed or non boxed, heard that boxed versions (OEM) could stand heat better than the bulk one.
3.Exatly which heatsink and fan should I buy?(really need a heatsink?
4.Where will I place the fan? (where the old one was?)
5.What does cC0 mean?
6.Do I have to set special settings on the Slocket? (celeron, speed, other stuff?)
7.The settings I should use are on iwill's homepage?

1. I think the Celeron 600Mhz cC0 should be your best choice for 900Mhz since so many people have had so many sucess with them.

2. Well the Boxed version comes with a fan and heatink, plus a 3 year warranty, but o/c'ing your cpu voids that. I don't know if there's a difference between a Retail or OEM version.

3. If your getting the Box version, it should come with a fan and heatsink along with the cpu. If not, maybe consider getting a Golden Orb fan/heatsink (it's only a bit better than the intel fan/heatsink that comes with the cpu)

4. You place the fan/heatsink on top of your cpu and should hook into place on the the Slocket Adapter's socket. If you buy the Box version, it should come with a instruction booklet and shows you how to put it on.

5. cC0 is just a stepping, or i guess it means a version of the chip. cC0 is the current stepping. But you might get a cB0 chip if the store carries older chips. You can tell from the label on the side of the box, it should say 1.7v if it's a cC0, and 1.5v for cB0, this should be the easiest way to identify the stepping.

6. Yes, you definitely need to set special settings on the Slocket, I listed them from my previous post.

7. No, the settings are not listed on iWill's page, but there's a label on back of the Slocket and should tell you exactly what jumpers does what. And all the possible jumper settings for the vcore (voltage).

But when I do the overclocking, will it affect any other parts of my computer? I've heard that speeding up for example fsb, speeds up all other components too, which destroys them

If I buy a boxed version, which fan should I replace the old one with to run 600@900Mhz with acceptable cpu-temp?

If I buy a non-boxed version, which heatsink+fan should I buy (also there most be enough space in the computer, so it fits, PEPP 66, is very big what I know)
if I will run it 600@900Mhz with acceptable cpu-temp?

No it wouldn't effect the other components in your computer, the maximum FSB your motherboard can run is 100Mhz. The only way you can affect the other components of your computer, such as your PCI speed is if you go over your fsb divider. But that's impossible to do if your using a iWill Slocket and running at 100Mhz FSB. Btw, i corrected the mistake i made from the previous post, increase your vcore by increments of 0.1v if your cpu doens't run stabily or doesn't boot. NOT 0.5v unless you want to fry your cpu.

And one thing, im fed up with frys, i've made to many trips there to find a damn Celeron 600Mhz cC0 chip which they don't even have it in stock, they gave me a cB0 last time. And there isn't any stores that sells cpu's here, and Frys is 40min away from me.

[n64spelaren]

It's hard to find 600Mhz celerons, wouldn't it be better and easier to clock a 633 or 667 Mhz instead?(633@900) (667@900)
How would I do then?
Same as with the 600?

If I run a 600@900, boxed,,,,,will the cpu run at acceptable temp then? (just so it don't get fried)

Actually no it wouldn't be better to clock 663Mhz and 667Mhz Celerons because of the higher multipliers. Im not sure what the multipliers are for the 633 and 667 celerons, but on the Celeron 600Mhz, it has a multiplier of 9.00x. So when you set the cpu to run at 100Mhz FSB, it'll be 9 x 100, 9 as your multiplier and 100 as your FSB speed, which equals to a total of 900Mhz clock speed of your cpu. The iWIll Slocket only gives you options of 66, 100, and 133Mhz FSB, so you can't have any other fsb clock speeds except those.The Celeron II are multplier locked, so there is no way of changing it. The Celerons II running above 900Mhz gets unstable and requires good cooling, so a 600@900mhz should be the best choice. I once gotten a Celeron 700Mhz cC0 stepping, and it's multiplier is 10.5x so... running that at 100Mhz fsb... 10.5 x 100 = 1050Mhz! I had to set my vcore to 2.0 or 2.1 to post! I set it all the way up to 2.5v and it still couldn't completely boot up windows. I could've fried that chip within hours, luckily i returned it. Good Luck

And Yes, if you get a cC0 600Mhz chip, it should probably run with the stock Intel fan/heatsink fine @900Mhz. The cC0 runs cooler than the cB0's and o/c's better without increasing the vcore by much. If you DO encounter temp problems with your cpu, you can always upgrade to a better heatsink.

thanks for everything, you've really been a help.

without you I wouldn't as much as now.
just wondering one thing, if I have to buy a new fan, what dimensions should it have? ( a 60mm fan)?

and how is the cfm of the original celeron fan

No Problem... glad to help out. I'm not sure what size you should choose, I've never really looked at heatsinks. But most likely the ones that are squared should fit it, just make sure it's for PIII and celeron flipchips or for Socket370 chips, even though it is not made by intel, doesn't mean it'll cool better than the stock one . You can always get the popular Golden Orb fan/heatsink, it's a round heatsink and should be very good, but only a bit better than the stock Intel fan/heatsink. You can add some Arctic Silver compound if you want, it helps transfers heat from the cpu to the heatsink.

And one more thing, the Celeron and PIII processors ONLY work if you have bios version A09 or higher. If not, then go to http://support.dell.com and download the newest bios. If you need more help, you can visit the Dell Forums too, from the support site just click on Communicate>Dimension>Upgrade Hardware and that should be where most of the cpu posts are.

[n64spelaren]

thanks man,
my system was shipped with Bios A09, and a year ago I upgraded to A13, :)

I am going to buy a Celeron Not Boxed 600Mhz and run it @900Mhz with a Golden Orb.
Hopefully it will work, what do you think?

One more thing, which is the fastest on my system, the P3 800Mhz or this Celeron @900Mhz?

(I feel sorry because I have no PCI left on my MB, therefore I can't upgrade my harddrive to ATA100, or can I?)

I don't know if the OEM or Non-Boxed version performs differently from the Retail or Boxed version, I've never gotten a OEM chip before, so I don't know. Maybe ask around the forum and see what people recommend you get. A Celeron 600@900Mhz is actually equivelent to a PIII 700Mhz, so no it won't perform better than a PIII 800. Check out this arcticle/guide they made about o/c'ing Celerons... http://www.sharkyextreme.com/hardware/guides/celeron_fcpga_oc/ they have many benchmark scores too for each Celeron, but the 600Mhz they test was a cB0 i think, because it took them a while getting it to run at 900Mhz.

Good Luck on your cpu upgrade and o/c'ing.
