PC Processors

[davemilter]

Today I combine my fresh and new stuff: asus prime x399-a motherboard, amd threadripper 2950x and

corsair memory (cmk32gx4m4b3266c16).

At first I run motherboard + cpu only without memory,

motherboard blinked constantly with rgb leds, fan rotated

and q-code show c0, but there is no such q-code in manual.

I install memory and it showed code e6, there is such q-code

in manul, but it is reserved for future use.

I install radeon rx560 into the first pci-e slot and there is no

picture on montior, code is the same e6.

Is this code shows that something wrong with CPU?

0xE0 – 0xE8 S3 Resume (PEI)

Enjoy, John.

I believe you misprinted the Corsair RAM MEMORY Part number. You probably meant this one that is listed on the Motherboard's QVL List: https://dlcdnets.asus.com/pub/ASUS/mb/socketTR4/PRIME_X399-A/PRIME_X399-A_memory_QVL_For_2nd_GenRyze...

Does any of your Motherboard Trouble LED are lit besides the Q-codes? https://dlcdnets.asus.com/pub/ASUS/mb/socketTR4/PRIME_X399-A/E13889_PRIME_X399-A_UM_V3_WEB.pdf?_ga=2... (This the PDF of your Motherboard Manual)

Make sure you have at least the 8 Pin CPU Power connected on the Motherboard if not both 4 & 8 Pin CPU Power connected:

When you power up the computer do you hear any extra or abnormal Beeps?
