Overclocking help!

[Ed Swayzy]

Hi there!

Any insight into my overclock inquiry would be greatly appreciated!

Here are the tech specs for my rig,
 

Intel - Core i5-9600K Six-Core 3.7 GHz Socket LGA 1151 Desktop Processor

 

ASUS - ROG STRIX Z390-E GAMING (Socket LGA1151) USB 3.1 Gen 1 Intel Motherboard with LED Lighting
MSI - GeForce RTX 2060 GAMING Z 6GB GDDR6 PCI Express 3.0 Graphics Card - Silver/Black
Cooler Master - Hyper 212 Black Edition 120mm CPU Cooling Fan - Black
Samsung - 970 EVO Plus 250GB Internal PCI Express 3.0 x4 (NVMe) Solid State Drive with V-NAND Technology

CORSAIR - CX-M Series 650W ATX12V 2.4/EPS12V 2.92 80 Plus Bronze Modular Power Supply - Matte black

I am looking to overclock the 9600k to 5.0 ghz but ive only been able to get the system to post by raising the core voltage to over 1.4V (specifically 1.425), which obviously is really high and stepping into dangerous territory for longevity.

I've been able to have a pretty stable OC at 4.8 ghz with a core voltage of 1.3

Any reason why the chip needs so much voltage for a stable OC at 5.0ghz?

Can't answer that question on the voltage but what temps are you running at? A Hyper 212 is a good aftermarket cooler to replace a stock heatsink, not for overclocking though.

Running at 30-40 degrees idle, and around 60 under full load. I ordered a Kraken x63 to replace the hyper 212, but idk if that will help with core voltage problem
