I have the CUBX motherboard and using the Celeron 1.0 ghz processor. I'm
looking at upgrading and would like to know what's the largest size of
processor I can go to using the celeron.


Thanks
Jeff

These are Tualatin FCPGA2 processors with 100MHz bus and 256KB cache.
They are cheap enough to consider for an upgrade. While Tualatin
processors are no longer being manufactured, there are still some
left at retail.

SL6CB B1 256 06B4 1000A 1000 100 FC-PGA2 1.500 13,15
SL6JQ B1 256 06B4 1000A 1000 100 FC-PGA2 1.500 2,13,15
SL6CA B1 256 06B4 1100A 1100 100 FC-PGA2 1.500 13,15
SL6JR B1 256 06B4 1100A 1100 100 FC-PGA2 1.500 2,13,15
SL6C8 B1 256 06B4 1200 1200 100 FC-PGA2 1.500 15,17
SL6JS B1 256 06B4 1200 1200 100 FC-PGA2 1.500 2,15,17
SL6C7 B1 256 06B4 1300 1300 100 FC-PGA2 1.500 15,16
SL6JT B1 256 06B4 1300 1300 100 FC-PGA2 1.500 2,15,16
SL6C6 B1 256 06B4 1400 1400 100 FC-PGA2 1.500 14,15
SL6JU B1 256 06B4 1400 1400 100 FC-PGA2 1.500 2,14,15

These "server version" processors run at 133MHz FSB and have twice
the cache (512KB). They are also expensive.
(From processorfinder.intel.com)

SL6BW tB1 06B4 1130-S 1130 133 512 - FC-PGA2 ? 1.450 - 20
SL6BX tB1 06B4 1260-S 1260 133 512 - FC-PGA2 ? 1.450 - 20
SL6BY tB1 06B4 1400-S 1400 133 512 - FC-PGA2 ? 1.450 - 20

You could overclock your current processor, and not have to
buy anything. The main benefit of doing that would be to
get some extra memory bandwidth from the faster bus.

In terms of the "feel" of the system, it won't feel that much
faster. (Yes, every little bit helps, but going from 1GHz to 1.4GHz
is not going to be a quantum leap.) The jump from X to 1000 would
have given you the most perceptable improvement.

Your current system
- 1000/100/128KB cache - could overclock to 1330/133/128KB
Cheap Tualatin
- 1400/100/256KB cache at 100MHz bus
- 1100/100/256KB cache overclocked to 133 ==> 1463/133/256
Expensive Tualatin
- 1400/133/512KB cache at 133MHz bus

Note: At 133MHz FSB, the AGP bus is at 89MHz, which overclocks the
graphics card interface a bit. Most modern cards can handle that.

Some nice PC133 CAS2 memory would be a good thing to have, if you
want to try running at 133MHz. If you have PC100 memory in your
system, then stick with a stock 100MHz bus speed.

Some stuff to read:

(Cheap adapter for Tualatin on S370)
http://www.upgradeware.com/english/product/370gu/370gu.htm
http://www.upgradeware.com/english/product/370gu/compatibility.htm

http://www.powerleap.com (PL-Neo/T is a cheap adapter $25 and PL-370/T
is more expensive and comes with a processor - check the compatibility
list to see what has been tried.)

I have a P2B-S that has run Tualatin 1.1GHz and Tualatin 1.4GHz, and
the slow memory bus and slow AGP bus hold the board back. Only a
new motherboard can give you a decent bus speed. When the board is
compute bound, I get the extra speed, but for most desktop uses, it
doesn't feel any different.

If you don't have it already, I would upgrade the BIOS to the latest
beta version, so there is a better chance that a new processor would
be recognized. Also, if the BIOS doesn't have microcode support for
CPUID 06B4, you can add it via http://tipperlinne.com/bios6b4.htm .

HTH,
Paul
