On the top of your Athlon CPU's plastic shell, you will see some numbers, which may be the same as the ID number on the internal board. Of course, you can disassemble the outer shell to see. The assumption is as follows: AMD-K7700MTR51B A 230013564242 AMD-K7 Family Architecture (k7 = Athlon, a = thunderbird) 700 700 MHz M package type (m = card module, p = PGA) T run voltage (T = 1.6V, P = 1.7V, m = 1.75V, n = 1.8V) R temperature (r = 70 c) 5 secondary cache (5 = 512K, 2 = 256K) 1 cache approximation (4 = 1/1, 1 = 1/3 ?) B Maximum FUR (B = 200MHz) a 0.18 micron core ('c' = 0.25 micrometer) 23 Production car room (23 Dresden Germany, 21 Austin Texas)
00 Years 13 564242 Sequence number (laser marking) K7 cache can be set to the core frequency 1/3, 2/5 or 1/2. 900 MHz of about 1/3 = 300 MHz 800 MHz 1/2 = 400 MHz (Unika)
