Had to RMA my 790i Digital *sadface*
Something very odd happened to me the other day, I had ordered the Cooler Master V8 for my Q8400 CPU, the machine was working fine earlier in the day, no issues, I install the V8, install it in my machine, thinking everything will be fine and that I shouldn't have to do a bench test, re-install everything, Hit the power button... no post. and I get an error code of F1. took out 2 of my 3 graphics cards and re-installed the ram, flashed the cmos and tried my old CPU cooler (Zalman 9700)... still get an error code of F1. I was on tech support with EVGA for a good half hour and couldn't figure anything out.

To make sure it wasn't a CPU issue, I took my Q6600 out of my media server and tried it in the board. It worked perfectly... I was thinking "this is odd." So I stuck the Q8400 back in the machine... got the error code of F1...:censored:.

But, Just to completely rule out that it wasn't the CPU I stuck the Q8400 in my media server's mobo (780i SLI FTW, Overkill for a media server, I know) And.. It worked perfectly fine. So I tried putting it back into the 790i and I got the code of F1... again.

So, Me being Me, I realized that I was using two different kinds of chips, the Q8400 is a 45nm chip whereas the Q6600 is a 65nm chip, leading me to believe that somehow the 45nm transistors got fried... I have no idea how that would've happened, since it was working perfectly fine before I put the cooler on. Let EVGA know and had to RMA it... I love this board though, but I'm planning to upgrade to an i7 and a classified hopefully in the near future :D

I was also having heat issues with the northbridge for a while before this happened, I had assumed the sensor was off, but it was telling me that It was sitting at 86*C Idle and over 92*C under load. anyway's, I just thought I'd share my adventure.
