Socket 1151 (Skylake + Kabylake) CPUs¶
WORK IN PROGRESS
Voltages:
| Voltage | Affects | Safe range (daily use) | Notes |
|---|---|---|---|
| Core Voltage | Core and Uncore (aka cache) | Up to 1.425V | n/a |
| DRAM Voltage | Memory | Up to 1.5V | DDR4 seems to break before IMC. Some sticks don't benefit from >1.4 |
| VCCIO | Memory Controller | Up to 1.22V | Increase to run higher dram mhz. |
| VCCSA | Memory Controller | Up to 1.25V | Increase to run higher performance dram - high mhz and/or aggressive timings. More needed with more ranks of memory. |
