鵝手邊沒有I社的design guide,剛看了一下A社的 BKDG for AMD Family 15h Models 00h-0Fh Processors是這麼寫的....

2.5.2.3 Mixed Frequency and Power P-state Configuration Processors with different CoreCOF, NBCOF, and power can be mixed in a system. All NBs must have the same number of P-states. All cores must have the same number of software P-states and all equivalent software P-states must have identical ACPI CoreFreq and Power settings.See 2.5.2.1.2.1 [Software P-state Numbering] and 2.5.2.1.11.2 [_PSS (Performance Supported States)].
• If MSRC001_00[6B:64][PstateEn, CpuFid, CpuDid, IddDiv, and IddValue] are identical for all software Pstates on all processors, then no BIOS modifications to MSRC001_00[6B:64] are necessary.
• If MSRC001_00[6B:64][PstateEn, CpuFid, or CpuDid] for any software P-state differs between processors,sections 2.5.2.3.3 [Mixed Frequency and Power P-State Configuration Rules] and 2.5.2.3.4 [Mixed Frequency and Power P-State Configuration Sequence] are used to determine the common set of P-states and define the required BIOS modifications to MSRC001_00[6B:64].
• If MSRC001_00[6B:64][IddDiv or IddValue] for any software P-state differs between processors and MSRC001_00[6B:64][PstateEn, CpuFid, and CpuDid] for all software P-states do not differ between processors,then 2.5.2.3.2 [Mixed Power P-State Configuration Sequence] defines the required BIOS modifications to MSRC001_00[6B:64].
• If D18F5x1[6C:60][NbFid, NbDid, NbPstateEn] are identical for all NB P-states on all processors, then no BIOS modifications to D18F5x1[6C:60] are necessary. Otherwise, 2.5.2.3.1 [Mixed Northbridge Frequency Configuration Sequence] specifies the required BIOS modifications to D18F5x1[6C:60].
• For all 16-bit coherent links that use 4-bit time operations, if the Northbridge and link frequencies do not meet the requirements in 2.12.4 [Link Bandwidth Requirements], BIOS must modify the link frequencies such that the requirements are met. This should be performed after 2.5.2.3.1 [Mixed Northbridge Frequency Configuration Sequence].

由以上敘述看來是可以混搭的,但會變成以低速/低功耗者為準,而且還有不少限制,所以通常不建議這麼用,不知I社是否也是如此就是了  .... |
