250X10達成
真是太奇妙了，
之前把所有的電壓都加到上限也不能上到2500內頻的cpu，
現在只要
CCV 1.95V
就可以達成了 :SSS:
不過之前2400內頻也是41秒，
現在2500內頻怎也是41秒?
難道是灌太多東西的關係?
等下來把北橋降壓看看...
現在是1.9V
我覺得應該1.8V就可以了

This info originally was credited to ASUS:
The problem is caused by a combination of power supply and motherboard +5V voltage ramp curves creating a situation where certain process corners in the ASIC will intermittently return an incorrect value for the ASIC ID after a cold boot.
Fix:
* Short-term solution is diligent screening prior to shipping.
* Long-term there are 2 options:
1. A modification to the motherboard BIOS (system BIOS) to create an extra read of the ASIC ID, the return value of which is ignored. The second read of the ASIC ID will then return the correct value
2. A board modification to monitor the read of the ASIC ID using programmable logic which will generate a NAK command back to the Northbridge controller while allowing the Radeon 9700 Pro to act as if the read command were executed successfully in order to cause the Northbridge to reissue the read command.
這個可能可以修理一些開機問題 :lkl: :QQQ:
