Microprocessor
The CC8-BLUES supports 370-pin PPGA and FC-PGA socketed Celeron processors and FC-PGA
housed Pentium-III processors listed below. The FC-PGA processors are also known as
Coppermine 0.18: generation (CPU ID 068xh). The CC8 is not suitable for newly available
Tualatin 0.13: FC-PGA2 processors. The CC8 is also not suitable for older 'slot style' Celeron and
Pentium-II processors. The Socket 370 also is not compatible with Socket 7 processors (e.g.
Pentium-MMX, K6). The table below lists typical processors available for the CC8-BLUES (there
might be other ressources not mentioned here). Please note: Use of any processor not
supported can cause permanent damage to the processor and the CC8-BLUES!
Neither have all of the CPU types mentioned in the tables below been tested by EKF for use with
the CC8-BLUES, nor does EKF claim that the entire range of processors is available for purchase.
Instead, please refer to the EKF price list http://www.ekf.de/liste/liste_20.html for availability of
the CC8-BLUES with particular processors (your individual request to [e-mail] is highly
appreciated).
Please do not attempt to change or remove the installed processor by yourself. The CC8-BLUES
is equipped with a non-ZIF processor socket, which requires special handling to remove the CPU.
In addition, the passive heatsink is fixed by several screws, which need to be precisely adjusted
in order achieve the optimum heat conduction. Furthermore, the heatsink is fixed with
conductive pads and/or adhesion to the Coppermine processors hot spot, which cannot be
removed and renewed without suitable material and knowledge. If it is required to identify a
particular processor, use suitable software instead, like Intels freely available Processor Frequency
ID Utility.
Do not confuse the processor host bus frequency (FSB front side bus) with the memory speed or
the PCI clock, which are independent from each other. The processor signals its appropriate
basic speed by two pins to the chipset, which is thereby adjusted automatically (no user
interaction required). The internal CPU speed is achieved by multiplying the host bus frequency
by a fixed value.
The CC8-BLUES is powered across the CompactPCI connectors J1/J2 (3.3V, 5V, 12V). The
processor core voltage is generated by a switched voltage regulator, sourced from the 5V plane.
Any FC-PGA 370 processor signals its required core voltage by 4 (Intel) dedicated pins, hence
there is no need (no choice) for user adjustment. Manipulation of these parameters (the
euphemistic term 'tuning' is widely in use for that) may lead to unpredictable results.
