other links can connect to I/O (non-coherent links); thus, 2000 series AMD Opteron processors can

be used in dual-processor systems. With the 8000 series AMD Opteron processors, all three

HyperTransport links can connect to other AMD Opteron processors or to I/O.

Processors—The Next Evolution in Computing."

Dual-core Revision F processors

The dual-core Revision F (Rev F) was introduced in 2006. A number of features from previous

revisions remained unchanged with the introduction of the Rev F processor:

• 64-KB/64-KB data/instruction L1 cache per core

• 1-MB L2 cache per core

• 1-GHz HyperTransport

Revision F also included key improvements:

• DDR2 memory support

• Hardware assisted virtualization (AMD V

• Power management (PowerNow!) improvements

• Quad-core upgradeability

DDR2 operates at 1.8 V compared to 2.5 V for DDR, reducing power requirements by up to

30 percent.

AMD Virtualization

hardware assistance directly supports virtualization with industry-standard

servers, which reduces complexity and improves performance.

PowerNow! Technology with Optimized Power Management reduces power requirements and heat

generation by reducing the processor's clock speed and voltage during periods when the CPU is

not fully utilized. Up to five power states are supported. Power consumption at idle is reduced by

up to 75 percent.

Quad-core upgradeability means that Revision F sockets are pin-compatible with and will support

quad-core processors within the same power and thermal envelopes.

HP ProLiant DL145 G3 servers do not support quad-core Revision F processor upgradeability.
