So got the new replacement PSU. The WEI noise is still there, but its as half as loud now - I think. Good enough...will stop paying it attention now.
So while pulling the FTW card out during my testings, I accidentally knocked off a surface-mount capacitor (or resistor, couldn't tell without any markings) off my Asus P8Z77-V Pro mobo right below the card. I managed to solder it back on - good thing I found it! However, in the process, I also managed to get tiny bit of solder on the adjacent IC that the capacitor was based around. It was the ACL892 chip, which is associated with the RealTek sound hardware that I use. Cleaned it best as I could but the pins are so small, it was very difficult to see how good of a job I had done. When I thought I was done, I powered it up, and sound seems to be working. At least for what I am using it for. Whew!
Talk about being careless.
Termie, the Heaven benchmark just crashes when one of those offsets are too high, saying the card was disconnected or something along that line - don't remmeber. When memory gets too high, I also start getting blotchy artifacts, at which point I lower the memory clock back down until they disappear.
