Celeron 1.4 GHz Question

[billybilly]

MY CPU:
Intel Celeron 1.4 GHz
Socket 370, FC-PGA2, 1400 MHz, 100 MHz System Bus, 256 KB L2-Cache

Is it safe to bump the FSB to 133 MHz with this CPU?

You can't destroy your Tualatin CPU by overcloking, except maybe if you use a very high Vcore. The 1400 MHz version has a default Vcore of 1.50V. Much more than 1.75V is probably not advisable in the long term.

I own a 1400MHz Tualatin Celeron. I'm only able to bump the FSB to around 122 stable (1708MHz) with Vcore=1.55V, using the stock cooler. The CPU temperature gets kinda high, around 58 degrees celcius running the Torture Test in Prime95.

When not overclocking, CPU teperature is still high when running Prime95, around 54 degrees celcius, and 48 degrees celcius idle. I think the combination of the heatspeader/(protective metal shield) and the lousy stock heatsink is responsible of this. A heatsink like the stock P4 heatsink would have been a lot better, after all, the Tualatin is using the same kind of heatspreader.

With the stock heatsink/fan combo, I can only up the Vcore by 0.05V. Higher than that, and the CPU will crash running Prime95 due to high temps. I think if you got yourself a high-end heatsink/fan combo you could likely go higher. In about two weeks I'll be trying out some quality watercooling equipment. This will pretty much give us an indication what this CPU is capable of. I hope to reach FSB 133, i.e 1867 MHz.

It will never reach 133MHz FSB. If you wanted a higher bus speed, you should have choosen a slower CPU.

While I agree with Crashman I must itterate that I hate the word never! Perhaps with liquid nitrogen cooling!

OK then, how high a FSB do you guys think I can take my 1400 MHz Tualatin Celeron using watercooling without a peltier.

Let's have a contest:

122 ~ 1708 MHz
123 ~ 1722 MHz
124 ~ 1736 MHz
125 ~ 1750 MHz
126 ~ 1764 MHz
127 ~ 1778 MHz
128 ~ 1792 MHz
129 ~ 1806 MHz
130 ~ 1820 MHz
131 ~ 1834 MHz
132 ~ 1848 MHz
133 ~ 1862 MHz
FSB above 133

I have no PCI/AGP ratio lock, so some of the above FSB could be a problem.

Anything less than FSB=130 ~ 1820 MHz will disappoint me.

Any other qualified bets ?

On an i815e board? I'm putting my money on 125Mhz FSB, for a 1.75Ghz Tually Celly.

[BuddyAtBzboyz]

Personally I doubt you will reach 133 even with watercooling but you might get lucky.

 

[Quetzacoatl]

Perhaps not, realistically, it won't. But heck, it would be undeniably cool to see a Celeron 1.4a do 1.86Ghz with a watercooler. You'd need a really good motherboard though...and it might even be more stable on an older BX platform, were it not for the pin incompatibilities. Shame Intel killed the socket370 line so fast.

Actually my 1400 Tualatin Celeron has the highest 3DMark2001 score among all Celerons on MadOnion equipped with a GeForce4 MX440 and Windows98.

More remarkably, my Celly has the highest Fill Rate (Multi-Texturing) score and High Polygon Count (8 lights) score among ALL CPU's on MadOnion with GeForce4 MX440 and running Windows98.

Way to go.

Hell, I even completed 3DMark2001 at 123 MHz FSB with the stock cooler, i.e 1722 MHz.

I have seen neither a Pentium 3 or Celeron based on the Tualatin core overclock over 1800Mhz in any computer, water cooled or stock cooling. I could run out and try for fun to test at a demo computer at a shop I visit often. I doubt you will get much higher, even with watercooling.

I could live with that, but I think watercooling will bring it further.

If I really had to, I could go out, and get a demo computer. I believe it's a custom design, on an i815e and Pentium3 tually 1.2Ghz.

I think the reason you did so well in the benchmarks copen is that not too many people go out and buy a celoron to save money then go out and bust the bank to get a good video card. But I could be wrong.

In some of the tests it's actually holding both my Celeron and other pretty hefty CPU's back from getting higher scores. What it shows though is, that there's no point in buying a top CPU/Motherboard and pair it with a mediocre 3D viodeocard if you are in to seious gaming.

By the way, the MadOnion 3DMark2001 score of my (stock cooled) Tualatin Celeron does only put me on the 48'th place among all users with MX440 and Windows98. The leader has score which is 1230 marks higher (21.8%). It's an Athlon XP running 1657MHz with 150MHz FSB.

[Copenhagen]

Sorry. I'm only on a 88'th place. (20 per page, not 10).

Well that make a bit more sense then.
