Hi, i've just upgraded my ram from a DDR4 F4-3200C16D-16GTZB to F4-3600C14D-32GTZNA, everything seems to work fine, the DRAM i have won't go into Command Rate of 1N, if i try it, it will NOT POST. Should i try what someone suggested in the HardwareCanucks forum recommended someone else and raise the voltage to make Command Rate 1N possible and by how much? These pair of RAM are not on the QVL as well on EVGA's site. Any suggestions?
F4-3200C16D-16GTZB Specs:
Capacity: 16GB (8GBx2)
Tested Speed (XMP): 3200 MT/s
Tested Latency (XMP): 16-18-18-38
Tested Voltage (XMP): 1.35V
F4-3600C14D-32GTZNA Specs:
Capacity: 32GB (16GBx2)
Tested Speed (XMP): 3600 MT/s
Tested Latency (XMP): 14-14-14-34
Tested Voltage (XMP): 1.45V
So I have:
Intel Core I7-9700k
EVGA Z370 Micro ATX
Noctua NH-D14
Nvidia GTX 1080 Ti FE
Things i've tried:
Tried to up the voltage from 1.45v to 1.5v and it didn't solve the problem.
Things i might need to try:
Changing memory timings manually rather than XMP
Changing VCCIO AND VCCSA voltages, IR_Cow & a user on reddit someone mentioned that you want to raise VCCIO to reach higher memory speeds and VCCSA to run tighter timings.
Quoted from IR_Cow:
I distinctly remembering needing to raise the SA and TX voltage for 1T to work.
From my 12900K notes I have written this if it helps for 1:1 Ratio. The more DIMMS you have, the higher the voltage you need. Also your motherboard and CPU IMC can change the voltages requirements slightly as well.
Speed / SA / TX / Command
3600 / 1.2 / 1.25 / 1T
3600 / 1.1 / 1.1 / 2T
3800 / 1.2 / 1.5 / 1T
4000 / 1.2 / 1.5 / 1T
4000 / 1.2 / 1.2 / 2T
4266 / 1.3 / 1.25 / 2T
