Dmi /peg bclk ratio overclock

Hi all been trying to get my head around the haswell dmi bclk ratio overlocking


As you can see all three are set to 100mhz

In intel ftic I can enable the dmi and set what frequency eg 125 mhz 5:4 not sure on upspread or downspread and then in amibcp I can enable icbc over locking and set the ratio and frequency from there

Has anyone achieved this route of over locking

Also I figured out it don’t work in dell service mode with me disabled

Anyone got any suggestions I have ways to fully kernel debug and write msr’s

I have dell 7810 2 x Xeon v3 2630 all cores 3.2mhz turbo unlocked

Thanks if anyone has any dell bios issues I’m happy to help out

Thanks
