Note: I'm using a Z170MX, BIOS F4d
CPU FLEX RATIO - the description in BIOS:
"Non Turbo Ratio: 8-35. Turbo ratio: 36. If out of range ratio, maximum or minimum ratio is used. This sets the maximum ratio."[/u]
If "it's" (assuming CPU Flex) out of what range? The non-turbo or the turbo range? And what does it set the maxmimum ratio of?
I've tried setting it both above and below x35, and both above and below my CPU multiplier with no observed affect on both load/idle clock multiplier, vcore, or power usage.
So what's its practical use and can it be used in conjunction with turbo, or is it supposed to be an alternative?
Can anyone help me understand it's intended use so I can determine if it's working properly on my motherboard?
Last question: The DVID. The description in BIOS says it "increases or decreases the upper or** lower voltage LIMIT of the CPU Vcore."
**or. This damn "or." If it truly is supposed to be "or," it would be nice to select which. In my experience it's "AND" - at load and idle - i.e., vcore reported in BIOS is exactly 1.2v+DVID, AND at load (minus vdroop) the +DVID is observed.
So it's an offset, not some intelligent dynamic thing as the description implies. As such I don't think you can undervolt soley an "at load" scenario, as booting becomes problematic with -DVID (so I've read, I'm using +DVID). Vcore is also always exactly 1.2v+DVID on the first page of BIOS (M.I.T.) and at max CPU multiplier.
If anybody has had different experience with these settings, or it seems to you I'm misunderstanding something, PLEASE CHIME IN HERE.
I really want to scrub the mystery out of CPU FLEX specifically.
