Hi I have read through some of the guides on here with regards to overclocking and using XMP but for the life of my I cannot figure out what I'm doing wrong, my issue is that I recently upgraded my DDR4 RAM from 2 dimms of crucial ballistics 4gb sticks to 64gb of Gskill 2800mhz ddr4 ram.

At the time I had my CPU over clocked to 4.5GHz and was extremely happy with that and was running my then crucial ram at its stock XMP profile without trouble.

I've tried running dimm at 1.3v system agent v at 1.15 (don't want to put volts too high as I'm not sure the safe level for voltages) my CPU Is the 5960x and I'm really trying to run it at a daily 4.5GHz, along with preferably my gskill kit that is rated at 2800mhz to be run at that speed if possible. Any help with voltages, and any other settings that I need to change will be much appreciated. I know 4.5ghz is possible on my sample as I've had it running there for months I can supply bios templates etc, also I'm running FULLY water cooled on all four of my GPU's and my CPU (RAM is passively cooled though)

Thanks in advance.

Martin
