1.55v XMP for AMD Optimized Kit.
1.55v XMP for AMD Optimized Kit.
The information suggests caution with the 1.55v kit. While your RAM supports 4000CL16 at 1.4v or CL14 at 1.55v, using 1.55v may affect performance stability and scores. The manufacturer likely avoids recommending it for AMD systems due to potential risks. Consider sticking to the lower voltage if you want consistent results.
The IMC is simply an Integrated Memory Controller built into the CPU. It requires a significant voltage and can damage the chip if it fails to communicate with RAM, which is essential for booting. Generally, Intel’s IMCs have been able to handle up to 1.6 volts, though official specs have stayed around 1.35 volts for some time. With Ryzen processors, I’m not certain about the limits. It would be wise to consult someone more experienced with Ryzen to verify this.
1.55 works well. 1.6 seems acceptable as well. I didn't encounter any issues.
4200mhz CL16, loose Trfc 1.65v 8700K 6.2ghz cache @ 5ghz - 1.60v Super PiMod under 6 seconds. Vccio and Sa 1.250v Fine tuned next time aiming to trim another second soon...
They suggest checking stock for CL14 1.55V and if available, it supports 1.55-1.6V safely. They mention load temperatures stay stable around 2°C with temps under 50°C being fine. The CL14 4000 still has uncertainty about the IMC, so they recommend opting for the 3600 model instead.
