Having experimented with over clocking the #nerdaxe and #bitaxe gamma, I finally decided to upgrade my #nerdQaxe++ rev6 from I added the rear fans earlier and have had the machine running at 750MHz for a while but didnt want to push it more as the ASIC chips have been running right at 60 degrees. So I finally added the Thermaltake Toughhair 110 CPU Cooler I picked up a while ago just for this. Initial results are great, besides being a little front heavy! With a 10 degree drop in ASIC temps and 7 degree drop in VR temps running at the same 750MHz. Im gonna let everything stabilize for a while but I looks like ive got some room to push the ASICs further!
