Hey guys, going along with my other post I wanted to share my Gem of a find. A 1.8ghz Sonnet card in the original box Nowhere to be found is its compatibility for the Cube. The highest clock I've seen from them is a 1.6ghz card. From what I found this card wasn't compatible because of power draw(?) I have replaced the stock VRM with a VRM upgrade I saw on eBay and had to figure out how to boot OS 9 (for the first time) and get the firmware upgraded. Thankfully it came with the disks and all documentation. Running the cube at scorching speeds now!!
