Support with 3900X Infinity Fabric 1800MHz OC issues
Mobo: AsRock X570M Pro4 : BiOS v1.80
Memory: Team Group Dark Pro 3600 (4 x 8GB)
Hi all. I'm attempting a really basic OC (relatively). I was hoping for a Memory OC up to 3600Mhz, which I've managed both manually and using XMP, both via the BIOS, and a matching infinity fabric OC of 1800Mhz (with a DRAM voitage of 1.35V).
The problem is that I can't achieve a boot with a corresponding FCLK speed of 1800MHz. I have to limit to 1600MHz for a successful boot. I've attempted enabling the SOC/Uncore OC option and setting the SOC voltage to 1.1V (I think my mobo has this value at 1.2V by default as when I attempt to change it, its default is 1200), but this doesn't help.
To state. The memory overclock seems to take fine with all 4 DIMMS reporting 1800MHz (not tested extensively yet), but IF has to be clocked to 1600MHz.
Any recommendations to small tweaks to get a successful boot?
