Overclock limited to 3.8 GHz, how to remedy?

In my system build, I have a Intel Pentium G3258 that I overclocked to 3.8 GHz since the thermals stay really low, only up to 65C on full load However, if I try to go to 3.9GHz and above, my computer either freezes up or blue screens. I don't have a GPU or anything that might be eating up power, my 500W PSU provides plenty of power, and I'm pretty sure I can push the CPU higher since it's only 65C full load. I heard others managed to get 4.1GHz on the stock cooler. I'm pretty new to overclocking, so I'm not sure what to do. Should I keep it like this, should I adjust the voltage or something else?
Parts List (probably the only parts that'd have an effect)t:
CPU: Intel Pentium G3258
Motherboard: Gigabyte Z97X-SLI
PSU: Zalman ZM500-RS
 
Solution
Higher OC's require higher voltage. Find a guide compared to your cpu/mobo combo and target close to what others have done. Each chip is different so your may or may not have similar/better/worse results. Guides give you an outline on how to best approach this.

So for example (disclaimer: conjecture only, not necessarily voltages you can actually apply), if you find a guide that has 4.1GHz at 1.25V Vcore perhaps you can achieve that as well but perhaps you may need higher Vcore of say 1.26V or your chip can be stronger and only needs 1.24V for the same 4.1GHz OC. It all depends. Once you can get this running without bsod then you stress test to help ensure stability. Tests like prime95 and intel burn test are the most common. You...

You must then keep an eye on your temps and make sure you are not throttling. If you get past all this then just common everyday use over the coming weeks will help see how stable your system is for your needs. If you play a game and it crashes then your oc is obviously not stable enough despite all the work you've don to this point.
Overclocking rewards the patient. If you are impatient your results will suffer. However, by being methodical and patient and having fun with the process of learning your specific chip much is to be gained! Have fun!

There is a good chance you aren't even actually "stable" at 3.8 GHz. Have you stress tested in with say a hour of Prime95 at 3.8 GHz to check for stability?

Thanks for the tip! I did find a few things while looking online and trying again while overclocking:
1. Tried 3.9 GHz at 1.2V and it still wouldn't work. Probably shouldn't go higher.
2. From Asus's website (for overclocking tips), apparently the integrated graphics is also probably eating up my power, which would make sense since I set the integrated graphics to 1300MHz. There happens to be a setting on my motherboard called CPU Graphics Core Voltage, it's on 0.000V right now. Any idea on what I should set it to? Thanks!
