Voltage for CPU when using 4 sticks of RAM.
Voltage for CPU when using 4 sticks of RAM.
I previously ran a system with 2 x 4GB RAM OC from 1600 to 2133, using the BIOS built-in profile without issues. Adding two more sticks caused it to fail. I checked that adjusting the CPU/NB voltage might be necessary to let the memory controller manage all four DIMMs. I increased the voltage in steps of .05, .075, and .1, but the system crashes at the login screen after each change. I confirmed the DRAM voltage and timing match the manufacturer’s specs.
I’m wondering if it’s best to start with the smallest voltage increase and reboot after each step. Could anyone give a general estimate on how much to raise in total to support four sticks? Also, what voltage jump could be risky for the hardware? Here are my specs:
Asus 970 Pro Gaming/Aura MOBO
AMD FX-8370 CPU – No OC
Two sets of G.SKILL Ripjaws X Series 8GB (2 x 4GB)
240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000) Desktop Memory Model F3-2133C9D-8GXL
FX processors encounter issues when both IMCs are applied to four memory slots operating at over 1600MHz.
CountMike shared his experience with FX processors using both IMCs for 4 slots filled with memory at 1600MHz. He was satisfied with the performance at 1866 with timings of 11-11-11-28. The stock timings at 2133 are 9-11-11-31. He asked if he could improve those timings and wondered whether the MOBO or processor would affect them, or if it would be possible as long as the RAM could handle it.
