Checking the information you posted, it seems that your system is working fine. The processor you have Intel® Core™ i5-5675C Processor (4M Cache, up to 3.60 GHz) Specifications, it has a graphics base frequency of 300 MHz and a graphics max dynamic frequency of 1.1 GHz which is the equivalent of 1100 MHz that you mentioned, if you trying to change that parameter that will depend on the V-BIOS on your motherboard, you might need to check with ASRock about this matter.
Hello zeqzy and thank you for your answer.
I´ve found this entry 'intLVDSSwingSetting' about ten or twelfe times at my registry, all containing the value '0'.
Could it be advisable to enter another value there? Another question is, what value is the real base clock rate
of a Iris Pro 6200, which clocks variable between 300 and 1100 MHz?
Ok I keep this at the back of one's mind, first I´ll wait for lamely ASRock supports answer (if they'll ever answer).
the information is found in the driver inf files
; 0x00 - Medium - Data and Clk Swing set to 298 mV
; 0x01 - High - Data and Clk Swing set to 320 mV
; 0x02 - Low1 - Data and Clk Swing set to 144 mV
; 0x04 - Low2 - Data and Clk Swing set to 170 mV
; 0x08 - Low3 - Data and Clk Swing set to 196 mV
; 0x10 - Low4 - Data and Clk Swing set to 220 mV
; 0x20 - Low5 - Data and Clk Swing set to 247 mV
; 0x40 - Low6 - Data and Clk Swing set to 273 mV
HKR,, IntLVDSSwingSetting,%REG_DWORD%, 0x00
this sets the voltage that is sent to the GPU the BIOS sets the voltage sent to the CPU and the value set here is the share of that power to be sent to the GPU
there is also an option to change the clock rate from what the GPU has set
HKR,, PNMClkDeviation, %REG_DWORD%, 0 ; Clock deviation value which is multiplied by 10.
HKR,, PNMFlags, %REG_DWORD%, 0 ; Bit0: Downward Deviation, Bit1: Upward Deviation. Bit2-31: Reserved.
e.g setting PNMClkDeviation to 20 and PNMFlags to 1 will lower 500 to 300
