Killer Trinity - top A10-5800k - confirmed 5.1GHz on air and 7.3GHz on LN2

[Himo5]

Talking of Asus Digi+VRM, here's some hard data that may be of some use as a starting point for OCing A10-5800K on the Asus F2A85's.

Using the standard APU frequency of 100MHz and incrementing the APU Multiplier from 38X to 50X I've attempted overclocks with the default Digi+VRM settings and then using the Smart Digi+ key in AI Suite II from 3800MHz to 5000MHz.

The CPU voltage required in each OC to pass 30 minutes in Prime95 is given with the number of 0.00625V steps above or below the default setting of 1.3125V.

Desktop installation for the test was:-
APU:Amd A10-5800K
HSF:Scythe Mugen 3b
MBD:Asus F2A85-V PRO
RAM:G.Skill TridentX-2666 2x4Gb
PSU:Seasonic X-760
HDD:WD1002EAX-1TB
CSE:Casecom KM5788

Non-default UEFI settings were:
AI Overclock Tuner [Manual]
APU Frequency [100MHz]
APU Multiplier [Auto] (Posts as 38x so this can be adjusted in AI SuiteII)
CPU Voltage [Manual mode]
AMD PowerNow function [Disabled]
CPB Mode [Disabled]
C6 Mode [Disabled]
OnChip SATA Type [IDE]
CPU_FAN Q-Fan Control [Enabled]
CPU_FAN Fan Profile [Standard]

Cooling was driven by my OCing (ie. loud!) fan set, consisting of two Scythe AP29-3000rpm GT fans modded and set in a PWM chain from CPU_FAN in a lateral push/pull configuration on the HSF to expel air through the cut out rear air vent and a Yate Loon 14cm/2300rpm 3-pin fan immediately above the HSF driven from CHA_FAN1 expelling air out of the case top through another cut out vent.
