Hi all,

Ive got the HD 4550. 1GB card. Though it seems the highest my memory can go is 500mhz. When I open the Catalyst control centre, the highest I can set it to is 500mhz. So I'm wondering why its advertised as 1000mhz, but I can only actually get half of that.

Thanks.

Ok, so that means I am getting 1000mhz out of it? Sorry but I'm still learning about video cards.

No problem. Same applies to system ram for example DDR2 800 runs at 400 but has effective 800 because of the DDR.

Yes if it is advertised GDDR3 at 1700Mhz then it would show as 850MHz.
