What is the best CPU to replace this Celeron CPU ?
Intel Celeron 1.3 GHz - OEM-RK80530RY013256 / Boxed-BX80530F1300256 ( PPGA370 ).
100mhz bus.
I don’t know if the motherboard supports 133mhz bus ?
Probably a Ryzen 7...
If you want a serious answer for something that will run on your motherboard, make the effort to find out what it is and let us know.
Well, if it supports the Tualatin Celeron, then it pretty much will support 133Mhz fsb.
What motherboard is it? Have you tried looking it up?
The only thing to go up from the 1.3Ghz Celeron is the 1.4Ghz Pentium III.
80530 is a Tualatin Celeron. As mentioned by cyclone3d, only step up is the 1.4GHz Pentium III (or Pentium III-s if supported).
All Tualatin PIIIs are 133 FSB, so as dionb states, you'll need to know your motherboard's capabilities.
Please use the "quote" option if asking questions to what I write - it will really up the chances of me noticing 😀
Every single board which officially supports tualatin, supports FSB 133 as well, all tualatin supported chipsets do FSB 133 officially and yeah, the only posible step up is the Pentium 3 1.4 or the Pentium 3 1.4-S
