So I have my 8700k at 4.8ghz on 1.320 voltage. It works fine but I’m wondering if i should reduce it to something lower then that number.

less voltage is always better, so yes, as low as you can while maintaining stability at 4.8ghz

Ryzen 5 3600 stock | 2x16GB C13 3200MHz (AFR) | GTX 760 (Sold the VII)| ASUS Prime X570-P | 6TB WD Gold (128MB Cache, 2017)

Samsung 850 EVO 240 GB 

138 is a good number.

you may wanna try setting it lower and lower 1 step at a time and do a quick stability test in between till you crash -> up it by 1-2 notches at that point and call it a day :D

I found when overclocking my 8700k, running RealBench stresstest for 15min wasd a good indicator of stable voltage before doing a much longer stress test.

I got;

4.7 @ 1.2v

4.8 @ 1.225v

and currently running 5 @ 1.315v

CPU ~ i7 8700k @ 5.0ghz 1.285v | Motherboard ~ Gigabyte Z370 Aorus Gaming 5 | Cooler ~ CoolerMaster ML360R (With Corsair ML120 fans)  

RAM ~ 16gb G.Skill Sniper X 3000mhz | GPU ~ Nvidia RTX 2080 FE | PSU ~ Corsair RM1000x | Case ~ CoolerMaster MB500

Ok so I’m now running at 4.8ghz @1.260v without any problems.

Should I try going to 4.9ghz or even 5ghz? I have the kraken x62 AIO cooler and the Asus rog strix 370-f mobo

You should be able to hit 5.0 with 1.30 or 1.32 max.

The only thing that’s keeping me from not overclocking to 5ghz is the temps. Right now I’m staying around 33-77 Celsius with 4.8ghz @ 1.260v

Try and lower your voltage as much as you can and run Realbench for 2 hours to see it's stability.

This is old photo but im doing 5.0Ghz @ 1.200 V now

With my room ambient at 30-35 normally.

Is that all 6 cores at 5.0?  IF so, damn nice voltage.

Should go for 5ghz @ 1.35 or max 1.375

Is there really that big of a difference between 4.8ghz and 5ghz when it comes to basic video editing and gaming?
