1312.5MHz on CopperMine core

2006-08-29 15:29:09
Posted by: Andy

Here is my Pentium III runing at 1.3GHz with homemade watercooling, the CPU stays in 30C, the bad part is that the onboard sound, vide, ethernet are not working at this FSB so I'm using a PCI sound, and network cards

Upgrading this from Celeron

I am planning to upgrade to the chip above(SL52R) from my Celeron 700MHZ. Its on a HP Pavilion XG823. Everything seems to match up can someone tell if this will work?

Upgrading this from Celeron

Response: Plase post upgrade questions in the forum.

Successful upgrade

2007-02-19 10:40:43
Posted by: Joe Strong

First of all I apologize for not posting in the forum.

The upgrade went successful from a Celeron 700Mhz to the above PIII chip. Of course it is recognized as 750Mhz because it's running at 100 FSB instead of 133. I could overclock but is this really wise when using the old heat sink and case fan?

Top processor for s370 motherboards without tualatin support.
1,5x more faster than Celeron 950mhz/128 L2/100fsb.
10% slower than Celeron 1300/256/100 (tualatin)

Because for mpeg4 movies pentium-2 is not enough, but pentium-3 series still good after 10years as home computer for watch movies/music/internet same as pentium4 :)

For aesthetes p3-1000 is best choice.

For s370 with tualatin support better look at
Pentium III-S tualatin (server version 512L2) 1400/512/133.

I got 3 GX110 (desktop versions) and they all had 866 coppermines... I dug around at an old warehouse and found some of these will let yall know how they run later.

My favourite vintage CPU

I bought a 1000/133/256/1,75 to "upgrade" my celeron-533 PC. It works great and runs XP Home SP2 with Avast 4.8 Pro quite good.
[u]Only problem[/u] : when I'm connected to the Internet,even if no web browser is opened, the Pentium runs at 100% !
