User error. I said: "The first turbo ratio should be set to 36…" but you've set the fourth turbo ratio to 36. Basically limiting the turbo ratios. Look here:
AICPUPMI: CPU Maximum Turbo Frequency........: 3600 MHz
Sorry about that. I'm quite new in this power management area so I don't get some of the terms.
I've been doing some tests in my system using the recomendations you gave and trying what other users have tried. All of these tests were done using manually set turbo ratios to 36,38,39,39 (the last three were the default auto values, I just entered them manually because seting them to auto didn't pass values to the system), as you can see here:
MSR_TURBO_RATIO_LIMIT......(0x1AD) : 0x24262727
SCENARIO 1:
For this test:
1. I loaded optimized defaults
2. set turbo values manually
3. configured CPU Clock Ratio to 35 and Uncore ratio to 35.
4. Turbo Power and core current limit were in Auto
In this test Processor Speed reports 3.59 GHz.
I only get P-State 8 but no other below 35 (only turbo ones)
SCENARIO 2:
For this test:
1. I loaded optimized defaults
2. set turbo values manually
3. configured CPU Clock Ratio to 35 and Uncore ratio to 39.
4. Turbo Power and core current limit were in Auto
In this test Processor Speed reports 3.59 GHz.
I only get P-State 8 but no other below 35 (only turbo ones)
SCENARIO 3:
For this test:
1. I loaded optimized defaults
2. set turbo values manually
3. configured CPU Clock Ratio to 35 and Uncore ratio to 35.
4. Set manually Turbo Power Limit to 84 Watts and Core Current Limit to 95 Amps.
In this test Processor Speed reports only 2.99 GHz.
I get a few P-States more below 35
I'm sticking with Scenario 1 configurations for now. As on scenario 3 I notice a wrong processor speed in system info when manually setting turbo power and core current limits. I don't know if this has an adverse effect on the system.
In any other test I got P-States below 35 (besides 8).
Can you give me any insight on these results? Is the processor speed reported by the system important?
Thank you!
