I got the corsair 2x16gb kit CMP32GX5M2B6000Z30, I did memtest86 tests and stresstests and it runs like expected, but somehow after a Bios update or choosing in ai tweaker "auto" or "manual" (bios update usually resets to "auto") I'll get the C5 error.
(I don't know much about voltage, timings... just choosing options)
I don't use gaming turbo mode or anything like that, or even PBO.
Basically only activating expo and tuning fan curves nothing else.
I don't really think that my ram is faulty, because it really runs very well with expo1,2,fly+
After the C5 error occurs, I have to follow following steps so everything works again:
>C5 error occurs
>taking the ram stick out, which triggers the c5 error
>going in to bios and choosing the expo1 (2, or expo on the fly+)
>waiting for ram training to end
>turn pc off
>put the stick back in
>waiting for training
And done
C5 usually means (as far as I know) compatibility error, there is something in this bios which triggers a bug with choosing those 2 options (a bios update resets the ram to the "auto" profile).
I would be very pleased, if this can finally be acknowledged.

a good rule of thumb i always follow regarding the bios, if it works. you do not update. if you dont understand the timings ect, stay out of the bios options.
