Yeah... But all celerons 1GHz and higher are Tulatin core chips. the major difference was 1) extra cache, 2) lower voltage on the bus. If it has most of the cache disabled, there is pretty much nothing to distinguish it from a coppermine other than the lower voltage and a cpuid that says otherwise.

Did it have a heat spreader on the chip, one that kinda looks like a P4? If it did its a tulatin chip.

but specified voltage is 1.75, not 1.45, it looks like a coppermine (no heatspreader), and intel did release a coppermine 1ghz and 1.1ghz celeron. thus making me believe this is a 1.1ghz coppermine and not tualatin, that why i bought this one and not the Tualatin version which was €20 cheaper.

Again, i know my hardware, and im not an idiot, i only dont know what could be making windows choppy.

Sigh, here we go again,

People seem to have this weird idea that they can upgrade their CPU's without also upgrading their motherboards

If you cannot resolve your problems, I suggest the following:

1) Refund your coppermine celeron and buy a tulatian CPU. You now have 30 pounds.
2) sell your old motherboard+CPU to a friend, who has an even slower computer. Install and set it up for them. You now have another 30-40 pounds.
3) Add another 20-30 pounds and buy a decent P3 motherboard that supports Tutalian CPU's out of the box.

I just checked Intel's site and indeed there is a 1.1 coppermine Celery... Well, now that we got that ruled out I'm out of ideas... Maybe some software is eating your CPU cycles? Dunno...

Knirfie do you use the ASUSR S370 Card or an other adapter for your celeron. And have you tried updating your bios to the latest bios (1005).

**MetalCartman** · 23 November 2002, 05:49

Another possible solution....

First, as KeiFront said, flash the newest BIOS, then check if L1&L2 cache are enabled in the BIOS.

Sometimes Windows NT/2k/XP doesn't recognize the right size of the 2nd level cache, but this can be resolved manually. Open your registry using regedit.exe and search for a DWORD named "SecondLevelDataCache". Change the value of it (zero is default which means auto-detection) to the size of your cache in kb, in your case either 128 dec or 80 hex. Reboot.

Good luck!

I use a soltek FC-PGA adapter and yes bios version is 1005 (upgrading to 1006 in a few minutes), MetalCartman, thx, for the tip, windows registry was set to 200 hex (512dec) and it now set to 128 dec. Restarting, will know more in a few minutes...

well, it took windows a lot of time to start but the laggyness seems to have disappeared.

thanks for your help guys

edit: very stupid spelling mistake.

Nice that you got that sorted out.

For those wondering about Tualatins & other wonders of the world, I have found this to be a good place for processor specs: http://www.geek.com/procspec/procspec.htm

also P2 = MMX, no SSE
Tualatin = SSE

**WyWyWyWy** · 23 November 2002, 13:55

So the problem was registry? or BIOS?

again, what does the tualatin have to do with it???? The coppermine also has sse but that shouldnt effect my performance in a negative way.

p.s. it was the registry

faster cpu = slower?
