Since the ATi HD5770 uses GDDR5 instead of DDR2/3, GPU-Z and GPUTool will not be able to analyze the Shader Clock. 2. Multiply the Memory clock by 4 (should be 1200, but I can be wrong) and you have your real memory clock (4800 or higher as you wanted). wa1 September 27, 2010 5:04:12 AM 1. My HD4850 shaders also on grey. (GPU-Z). 2. That's normal, your card is on idle state so it throttled down, if you do some 3D works or gaming then your clock speed would raise to 4800.

Since the ATi HD5770 uses GDDR5 instead of DDR2/3, GPU-Z and GPUTool will not be able to analyze the Shader Clock. That is quite incorrect.The shaders on ATI cards are grey because ATI have same Shader and Core speeds.The are not differentiated, unlike Nvidia cards where Shader speed is twice the Core speed.
