Hello, Recently upgraded to a 3600 from an i5 4690k...so a big upgrade and never had to deal with infinity fabric at all.

I'm aware that the RAM speed and infinity fabric should be matched to ensure optimum perfomance hwoever my PC fails to post at 1800 and if all values are set to default it runs at 1600 (which im aware is stock)

Currently using Corsair Vengence Pro 2x16GB Ram (CMW32GX4M2Z3600C18) rated for 3600 C18

Using Ryzen Master I've managed to get the Fabric at 1767 with the ram to match with tighter than advertised timings thanks to the DRAM Tuner at 1.35 volts.

with the RAm on its XMP profile and infinity fabric manualy set to 1800 i dont even get a post, with IF set to auto it comes in at 1600.

Is there anyway i can get the Infinity fabric to run at 1800mhz to match my advertised ram speed ?

I've also ran the Clock tuner diagnostic to see if i could eek out some more perfomance hwoever i got to round #32 of the diagnostic after what seeemed to be an age with no result.

Would i be better off just using the auto overclocking button within ryzen master ?

Picture is with Multi core cinebench running in background for reference.

Edit: USing an ASrock B550mITX AC board
