換上許多驅動....終於8.66.6b4 for W7 x64是比較穩定的;em25;
所以之前對HD4870的測試全都從來!;oq;
P55 LGA1156空冷裸測平台,室溫27度C沒開空調:
CPU:I7 870@4G(200x20)
M/B:MSI P55-GD80 164 beta BIOS
MEM:創見D9KPT DDR3 1333@2000 9-9-9-27-66-10-5-5-5-27
VGA:MSI R4870-MD1G CYCLONE
HDD:7200.11 500G
COOLER:HDT1283
PSU:
影隼600W
OS Windows7 X64 7600RTM
驅動:
ATi 8.66.6b4 for W7 x64(ati-opencl-beta-driver-v2.0-beta4-vista-win7.zip)
4870待機: 170W
4870跑Furmark
此時4870全速是281W,整機功耗提升不少,所以500W跳電連連故換上影隼600W:lkl:
比對之前的5770功耗:這樣不必換PSU,500W就能搞定!:MMM:

所以買5770不必換PSU,又能省電,又支援DX11;em25;等下POST 閃點行動2巨龍崛起 :D
