[情報] AMD/ATI 4870 測試版BIOS釋出
Found an engineering version of the HD 4870 bios, version 113-B50701-105 at
http://gathering.tweakers.net/forum/list_messages/1305107/1
Use at own risk!
First tests on a regular HD4870 by the original poster (The_Firefox) show
that a considerable power reduction in 2D can be achieved with the voltage
and memory frequency switching supported in this bios:
GPU @ Voltage, MEM freq, VRM (measured in EVEREST)
500 @1.263, 900, ~26A
550 @1.1, 900, ~22A
550 @1.1, 500, ~14.25A
看起來測試版bios已經大幅降低待機功耗。
目前自己的4870待機下仍然有35A的耗電量!
請注意!本人沒有測試!!請使用者自行負擔使用風險。
