Hello GSkill :)

I got a ASUS ROG Maximus IX Apex and a Trident Z RGB - 4266 Mhz Kit (F4-4266C19D-16GTZR)...
On it is a 7700k and a MSI GTX 1080 Foundersedition...
But i wasnt able to get 4266 Mhz.. max i got was 4100 Mhz after much time...

Is it possible i got a CPU with a bad Memorycontroller or is there anything else i could do?
or could it be the RAM?`
CPU itself runs at 5.1 Ghz but i also tried at Stockspeeds but that didnt help to get the ram running at 4266 mhz

It's not a bad memory controller, it's actually very good. Not every i7-7700K will be capable of DDR4-4000+ so what you are experiencing is normal.

What is the VCCIO and VCCSA Voltage @ DDR4-4133? May need to manually set it higher to reach a higher frequency.

Hello!
And sorry for the late answer...
Wasnt able to get infront of my computer lately..

Well i just checked the Voltages you were asking for..
I just now set VCCIO and System Agent Voltage (i assume this is VCCSA) to Auto with the RAM sitting @4 Ghz atm...
While the Settings where on Auto i got those Voltages:

DRAM Voltage: 1.408 V
CPU VCCIO Voltage : 1.264 V
CPU System Agent Voltage : 1.296V

I got told those nearly 1.3 Volts are already pretty high what do you think?

Are there any other Voltages that i may need to change?

Thanks again!
