Decoupling Guidelines
Due to its large number of transistors and high internal clock speeds, the Dual-Core 
Intel
® 
Xeon
® 
Processor 5100 Series are capable of generating large average current 
swings between low and full power states. This may cause voltages on power planes to 
sag below their minimum values if bulk decoupling is not adequate. Larger bulk storage 
(C
BULK
), such as electrolytic capacitors, supply current during longer lasting changes in 
current demand by the component, such as coming out of an idle condition. Similarly, 
they act as a storage well for current when entering an idle condition from a running 
condition. Care must be taken in the baseboard design to ensure that the voltage 
provided to the processor remains within the specifications listed in 
. Failure 
to do so can result in timing violations or reduced lifetime of the component. For further 
information and guidelines, refer to the appropriate platform design guidelines.

Decoupling
Vcc regulator solutions need to provide bulk capacitance with a low Effective Series 
Resistance (ESR), and the baseboard designer must assure a low interconnect 
resistance from the regulator (EVRD or VRM pins) to the LGA771 socket. Bulk 
decoupling must be provided on the baseboard to handle large current swings. The 
power delivery solution must insure the voltage and current specifications are met (as 
defined in 
). For further information regarding power delivery, decoupling 
and layout guidelines, refer to the appropriate platform design guidelines.

Decoupling
Bulk decoupling must be provided on the baseboard. Decoupling solutions must be 
sized to meet the expected load. To insure optimal performance, various factors 
associated with the power delivery solution must be considered including regulator 
type, power plane and trace sizing, and component placement. A conservative 
decoupling solution consists of a combination of low ESR bulk capacitors and high 
frequency ceramic capacitors. For further information regarding power delivery, 
decoupling and layout guidelines, refer to the appropriate platform design guidelines.
2.3.3
Front Side Bus AGTL+ Decoupling
The Dual-Core Intel
® 
Xeon
® 
Processor 5100 Seriesintegrates signal termination on the 
die, as well as a portion of the required high frequency decoupling capacitance on the 
processor package. However, additional high frequency capacitance must be added to 
the baseboard to properly decouple the return currents from the FSB. Bulk decoupling 
must also be provided by the baseboard for proper AGTL+ bus operation. Decoupling 
guidelines are described in the appropriate platform design guidelines.

Front Side Bus Clock (BCLK[1:0]) and Processor 
Clocking
BCLK[1:0] directly controls the FSB interface speed as well as the core frequency of the 
processor. As in previous processor generations, the Dual-Core Intel
® 
Xeon
® 
Processor 
5100 Series core frequency is a multiple of the BCLK[1:0] frequency. The processor bus 
ratio multiplier is set during manufacturing. The default setting is for the maximum 
speed of the processor. It is possible to override this setting using software (see the 
Conroe and Woodcrest Processor Family BIOS Writer’s Guide). This permits operation 
at lower frequencies than the processor’s tested frequency.
