TUSL-2C Celeron 1000==>1300 ?

[a-lehmann]

I use a Celeron 1000 on a TUSL-2C mainboard. FSB set to 100 MHz.
I want to use 133 MHz SDRAM and thus set the FSB to 133 which is a BIOS
option. But in this case the CPU would run at 1333 MHz instead of
specified 1000.
Do I have to expect a damage to the CPU?
Of course 33% is a large amount of overclocking. But I read about and
tried myself successfully to run a Celeron 566MHz at 830MHz by changing
FSB setting from 66 HMHz to 100 MHz (MSI Adapter from socket 370 to
slot1; there are jumpers to set that).

So I assume a similar ratio might me set with this Ceöeron 1000.
Des anybody know more about it?

Thank you in advance

Just as a note, PC133 SDRAM will also work fine at 100 MHz...

Is that a Coppermine or Tualatin core Celeron (128K vs. 256K L2 cache)?
I doubt a Coppermine would easily o/c so high (the core tops out at
1200-1300 MHz even for cD0); the Tualatin, however, should manage this
without much effort. Fairly cost effective setup.

....and that's being optimistic, at least in my experience.
Most 100MHz CuMines I've tried started having stability
problems at somewhere between 110 and 115MHz,
(1.10 - 1.15GHz), regardless of the amount of cooling.

I use a Celeron 1000 on a TUSL-2C mainboard. FSB set to 100 MHz.

I think the fastest official P3 Cu CPU (P3 with 256K) have 1200MHz.
I can also remember the first 1000MHz (1998 or so...) P3 which was
getting very very hot and was reduced to 85 degrees temperature max.
instead of 90 like your Celeron.
Maybe you could drive your CeleronCu with liquid Oxygen to 1333MHz. Who
knows.

No, the transistors in Intel CPU´s do as they should do. When
overheating closes the Transistor the circuit, no current anymore means
no power and without power no heat.

Of course 33% is a large amount of overclocking. But I read about and
tried myself successfully to run a Celeron 566MHz at 830MHz by
changing FSB setting from 66 HMHz to 100 MHz (MSI Adapter from socket
370 to slot1; there are jumpers to set that).

Yes, the smaller MHz Version are rated more. A high MHz one is just a
better selected one. With some variations, off course, but too long to
tell all I know.
For example: A 766 Cel is a 1000 Cel, A 533 is a 700.

So I assume a similar ratio might me set with this Ceöeron 1000.

Your CPU is the top of the limit model in this series of family 6 Intel.
So the possible overclocking percentage is decreased!!!
A 550Mhz Cu you can drive up to 840MHz. Thats more than 33%
A 1000!?, I would say about 1200Mhz, like the fastest existing P3.

Or, A 1133 Tualero could work (should) at 1300MHz
and a 1133 P3-S at 1400 and so on......


You can also study datasheets from Intel, which model and stepping your
CPU is and see the maximum MHz models, don´t forget to watch the
stepping ID.

Good Luck!

No, fastest P3 Coppermine was 1100Mhz (100Mhz bus no less), unless you
count the 1133Mhz P3 which was never released to public as it didn't run
stable in reviews... (the unstable 1133Mhz P3 was a cB0 stepping, later
steppings would have easily run at 1133Mhz though, but intel rather
wanted to sell P4 at that time and probably wanted to avoid being
reminded about the cB0 1133Mhz P3 disaster).

Hi Roland!



Well, if I would not see it myself I would say the same.

A local computer shop had one. iP3 in a Box 1200MHz (possibly 9x133MHz).
Maybe I saw it wrong, but I am pretty sure.

It was a Tualatin. Everything over 1100MHz is.
