AMD Opteron 2P 2300 series Quad-Core processor (Barcelona)


Model name: Opteron 2P 2300 series Quad-Core.
Code name: Barcelona.
Family name: Cities.
Supplier: AMD.
Component class: CPU.


Generation: K10.


64 bit technology: AMD64.

Multimedia instruction sets: MMX, Enhanced 3DNow!, SSE, SSE2, SSE3, SSE4a.


Balanced Smart Cache:

  • L1 cache: (4x) 64 kbyte instruction cache, 64 kbyte data cache (Harvard architecture),
    both 2-way set-associative,
  • L2 cache: (4x) 512 kbyte,
    8-way set-associative,
  • shared L3 cache: 2 Mbyte,
    32-way set-associative.


128 bit (decoupled dual-channel), 166/333/667 MHz, Registered DDR2-667 memory controller, supporting ECC (Error-Correcting Code): max. 8 x 512 Mbyte = 4 Gbyte (4 x 1 Gbyte double-sided PC2-5300R (ECC) memory module) per processor.

1000 MHz HyperTransport 2.0 bus.

Memory protection: NX bit (Enhanced Virus Protection, EVP).

Virtualization technology: AMD Virtualization (AMD-V, Pacifica), with:

  • Rapid Virtualization Indexing: Nested Page Tables, virtual-to-physical address translation by memory controller,
  • Tagged TLB (Translation Look-aside Buffer): linking memory pages to virtual machines, no need for TLB flushes when switching virtual environments,
  • Device Exclusion Vector (DEV): managing access to memory pages by virtual machines,
  • Extended Migration: allowing virtual machines to be live migrated over the full range of Opteron processors.


Quad-core technology: four cores connected through Internal System Request Queue Crossbar.

Multi-processor support: dual processor, connected through HyperTransport bus.


Power management

Power management: Enhanced PowerNow!, with:

  • CoolCore Technology: turning off unused parts of the processor,
  • Independent Dynamic Core Technology: the clock multiplier of each core can be set independently of the other cores,
  • Dual Dynamic Power Management (DDPM): a split power plane provides an independent power supply to the cores and to the memory controller.
