[SOLVED] Huge latency after installing 3200MHz RAM

Hello everyone!

So i got a new GPU and wanted to up my build a little bit in other areas.

Right now i have:

CPU: I7-8700K running stock / 4.6 OC
Motherboard: Gigabyte Z370 HD3P F14 BIOS
New RAM: G.Skill F4-3200C16D-16GVKB - 3200 MHz with CL 16

Tried XMP to 3200 and manually setting up 3200 with 1.35V, but it seems like my latency is extremely huge. Tests were done with stock CPU settings.

Test results and system information

It seems that my memory bus is super low, how can i change that?

Any advice?

P.S. I'm having problems OCing my CPU too, because everytime i set CPU voltage to anything higher than 1.225 my temps skyrocket to 90-100 in tests like cinebench r23. Reinstalled my cooler, changed paste, changed my watercooler to a standard one, nothing changes. Before installing my CPU i went to a repair shop to delide it, everything went fine as they said. With stock settings everything is fine and it's around 70-75 during load. Don't know if it's related.

Seems like it's solved.

I disabled intergated graphics and VT-d in BIOS and updated my AIDA version to 6.70. Now latency is 56.7 and everything else is really fine.

Thanks everyone!
 
Load BIOS defaults and try again.

Or, check DRAM Frequency / System Memory Multiplier and CPU base clock

DRAM Frequency is DDR4-754

CPU FSB shows 23.6 when it should be 100, so it seems like overall the computer is set to run 1/4 of it's normal capability.

Are those temps Fahrenheit or Celsius? They would seem high if Celsius

Sorry for the incomplete post. Temps are Celsius

Tested everything with bios default settings and it's still the same. Latency jumped to around 310 ns

Bios defaults to 2133MHz Frequency too. XMP pumps it to 3200.

It's weird that tests show such metrics. I'll try a different program to test the latency

So i tried Intel memory latency checker and the results are like this:
