i5 6600K requires specific RAM OC voltage settings with GSKILL.
Hi everyone!
I recently upgraded my i5-6600K to a 4.4Ghz processor with auto-voltage. At first, I didn’t adjust the voltage manually, but it changes automatically based on clock speed. While testing Prime95 for 15 minutes, it reached a maximum voltage of 1.328V, which seems acceptable and not too high. Do you think it’s better to set a fixed value, use adaptive voltage, or just let it auto?
Also, regarding the RAM: the default voltage is 1.2V, I have a 16GB G.Skill kit rated at 3200MHz, but running it at that speed caused issues, so I limited it to 2666MHz. The auto-voltage reads 1.35V. Should I lower it to 1.3V or keep it at 1.35? The manual says 1.35 is the rated value, but since I’m not pushing the CPU to its max speed, would lowering it still be okay?
Other details: Asus ROG Maximus VIII Ranger motherboard, Corsair H110i GTX AIO cooler, Strix R9 390X GPU, Corsair RM750i power supply, and this is my first time overclocking. Any advice would be greatly appreciated!
For the i5, I own an i7 of that same class which is also overclocked. My current setting is 4.4 Ghz around 1.31, which isn't ideal. Don't enable adaptive or auto; it'll draw excessive power than necessary. I experienced this firsthand. I wouldn't exceed 1.34v.
For your RAM, keep it at the default if you have an XMP profile enabled. These presets ensure the advertised speed but offer minimal real-world difference—perhaps just a few frames per second if you're lucky. Boosting the VRM on the CPU will likely give better FPS than adjusting the RAM settings.

If you do, it will consume significantly more power than necessary. I experienced this firsthand. I wouldn't exceed 1.34v.
For your RAM, keep it at the default if you have an XMP profile enabled. These presets ensure the advertised speed but often result in minor timing and voltage differences—possibly just a few frames per second improvement at best.
For the i5, I own an i7 from that same line that's also overclocked. I achieved around 4.4 Ghz at about 1.31, which isn't ideal. Avoid adaptive or auto settings; configure it manually. Auto mode will consume significantly more power than necessary. I experienced this firsthand. I recommend staying below 1.34 volts.
For your RAM, keep it at the default setting unless you have an XMP profile installed. These presets ensure the advertised speed but can result in minor timing and voltage differences. In practice, these might only affect performance slightly—perhaps a few frames per second if you're lucky.
Overclocking your VRM will likely give better FPS results compared to RAM. I've set it manually at 1.28v, and it still performs well when monitored via HWmonitor. I attempted 1.29v, reaching a maximum of 1.328, then lowered it back to 1.28v during stress tests. This behavior seems normal. I also increased the multiplier to 46, now hitting 4.6ghz at 1.28v (as shown by HWmonitor, mobile module, and CPU-Z). It appears stable, and after running Prime95 for an hour, no issues have arisen. This is the expected outcome when testing under load.
For RAM, I'll maintain it at 2666mhz at 1.31v.
