I am hoping this will be an easy fix. I am running an Aorus Z390 Master, I9 9900K, 32MB DDR4 RGB RAM 3200MHz by Aorus, and an Aorus Geforce RTX 2080 Xtreme Waterforce GPU. Waterblock is an EX - Supremacy MX
Before completing my custom loop, everything worked perfectly.
After installing the water-block, completing the loop and utilizing the GPU - I couldn't boot. Error codes were cycling through C codes and landing on 4C before finally landing on C1 where it sits for about 2 minutes finally shutting down and starting the cycle again. Of course the codes have no definition in the book and I've not been able to locate their meanings elsewhere.
I tried another power-supply with same result.
I removed all the RAM but one stick and it booted.
I used that RAM in every slot and it booted.
I test all other RAM in the same way... it booted.
If I tried more than 1 stick of RAM, problem presented again. I tried both channels 1 and 2.
After research, I found that tightening the back plate too tight for the water-block has been known to cause this, so I tore the loop completely down. While it was down I reinstalled the original back plate and put the air cooler on along with all the RAM and it booted just fine.
I then reinstalled the back plate again taking care to only snug the back plate and water-block.
I now have use of all 4 modules of RAM with the loop intact; however, If I enable the XMP profile.... the same problem and codes described above returns.
I am at a loss.
I've done all the obvious: check the voltage profile, bios firmware, clear CMOS, ect.
Does anyone have any ideas on the next steps I should take?
I have also noticed that the EZ OC options in the BIOS now say something along the lines of Not Supported
