This motherboard supports both Pentium III & Celeron 370 pins CPU.
The way to recognize the specification of CPU from the packing Pentium III 370
pins FC-PGA
On the surface of the CPU as shown on the right picture, under the word of
“PENTIUM III” the code is:
pins FC-PGA
On the surface of the CPU as shown on the right picture, under the word of
“PENTIUM III” the code is:
RB 80526 P2 866 256
RB :
FC–PGA packing
P2 :
P2–133MHz front side bus frequency
PY–100MHz front side bus frequency
866 :
CPU internal frequency, where here is
866MHz
256 :
the size of L2 cache, where here is 256K
Celeron FC–PGA
On the surface of the CPU as shown on the right picture, under the word of “Celeron”
the code is:
566/128/66/1.5V
566 :
CPU internal frequency, where here is 566MHz
128 :
the size of L2 cache, where here is 128K
66 :
front side bus frequency, where here is 66MHz
1.5V : the voltage for the CPU
