After a fair bit of trouble I've finally got my new HIS X1800XL working (almost) properly, and at reasonable temperatures (57*C idle, was 90*C). Anyway I still have one remaining problem, I can OC the GPU with CCC fine - I have it at a 'requested' 575MHz, but as soon as I try to ramp up the memory clock speed, whether it be an extra 50MHz or just an extra 5MHz, as soon as I click 'Ok' or 'Apply' my computer just shuts down and reboots. Anyone know why this might be?
Someone suggested to try ATI Tool, but that doesn't really explain why this is happening.
