Target Turbo Mode Frequency too high?

[Arcade_Portal32]

I have an Intel Core i7 4790k, 16 gb Ram xmp, 4 HDD not in RAID, Corsair H100iGTX liquid cooler, gtx 970, ASUS ROG Maximus VII Hero mobo.

I been having BSOD for the past couple months now, I finally beleve I found the issue.

Here are the target frequency speeds currently set in the BIOS. I have not messed with much other then the RAM speed settings In the bios readout

Target CPU Turbo-Mode Frequency: 4800Mhz
Target DRAM frequency: 1600Mhz
Target Cache Frequency: 4000Mhz
Target DMI/PEG Frequency: 100Mhz
Target CPU Graphics Frequency: 100Mhz

BIOS voltages
+12v is 12.192
+5v is 5.080
+3.3v is 3.376

All the BSOD are hardware related and I beleve the target CPU Turbo Frequency is set too high?
Is my assumption correct? I'm relatively new to the custom PC master race, and this is my first build. I'm tired of the BSOD, and I'll post the BSOD data if requested thank you

Very few 4790K will be able to run ar 4800mhz stable - most top out around 4500-4600mhz. I would recommend setting everything back to stock - there's very little to be gained from overclocking that CPU, since at stock it's already very close to the max frequency it's likely to be stable at.

I set the BIOS tuning mode back down to normal mode
The the boost speed is now set at 4400Mhz, is that ok?

Just to be sure, you should load optimised defaults so you reset all settings(if you know how to set boot priorities, uefi etc.). And yes, the default is 4400.
