B0baganooshwell...I had been tinkering a bit, and yesterday figured out my memory was at 16-16-16-39. I was like "wait, I thought it was at 16-16-16-36", so I changed it. Then I noticed today in HWiNFO64 that I was getting tons of WHEA PCIE errors. every 30 seconds or so, like you were. So I says to myself: "Self, what did you change because this is new" and remembered the memory setting. I just changed it back to 39 from 36 and they're gone. Hasn't been more than 45 minutes booted up, but they seem gone for now...will advise at a later date.
frankd3But what would the ram have to do with a pci-e error?
