Used for gaming, litecoin mining, 3D rendering, programming and CAD (mechanical/electrical)
Windows 8 and the Killer NIC on the motherboard have a compatibility problem which causes the network monitor to continuously eat up non-paged memory in a 1:1 ratio of all traffic across the NIC. This eventually caused the system to run out of memory. Disabling the network monitor service is a usable workaround with no notable impact to the system stability or performance.
Stock cooler on the R9 290 is awful as anyone would tell you. The Xtreme III worked well in keeping core temps down, VRMs idle around 35 degC and will peak to ~84 degC running stuff like Furmark/litecoin mining but usually mid-70s for gaming. The Xtreme III doesn't have enough heatsinks for the RAM chips so I took four of the long and narrow heatsinks and placed them across four chips - each heatsink spanned across two chips covering half of their width. I also had to cut one of the heatsinks for the RAM chip closest to the PCI-E socket connector using a Dremel in order to make it fit. GPU core is using Noctua NT-H1 thermal paste and VRM/RAM chips all use t-Global LI98CN thermal tape to interface with the heatsinks allowing for rework.
