Both Intel

®

 Server Board S5520HC and Intel

®

 Server Board S5500HCV support the 

following DIMM and DRAM technologies: 



 

RDIMMs:  

– 

Single-, Dual-, and Quad-Rank 

– 

x 4 or x8 DRAM with 1 Gb and 2 Gb technology, no support for 2 Gb 
DRAM based 2 GB or 4 GB RDIMMs 

– 

DDR3 1333 (Single- and Dual-Rank only), DDR3 1066, and DDR3 800 



 

UDIMMs:  

– 

Single- and Dual-Rank 

– 

x8 DRAM with 1 Gb or 2 Gb technology 

– 

DDR3 1333, DDR3 1066, and DDR3 800 

The Intel

®

 Xeon

®

 5500 series processor connects to other Intel

®

 Xeon

® 

5500 series processors 

and Intel

®

 5500/5520 IOH through the Intel

®

 QPI link interface. The frequencies of the processor 

cores and the QPI links of Intel

®

 Xeon

®

 5500 series processor are independent from each other. 

There are no gear-ratio requirements for the Intel

®

 Xeon

®

 Processor 5500 Series. 

Intel

®

 5500/5520 IOH supports 4.8 GT/s, 5.86 GT/s, and 6.4 GT/s frequencies for the QPI links. 

During QPI initialization, the BIOS configures both endpoints of each QPI link to the same 
supportable speeds for the correct operation. 

During memory discovery, the BIOS arrives at a fastest common frequency that matches the 
requirements of all components of the memory system and then configures the DDR3 DIMMs 
for the fastest common frequency. 

In addition, rules on the following tables (Tables 3 and 4) also decide the global common 
memory system frequency.
