Is my card underclocked? Tags: Radeon Sapphire Graphics Last response: January 4, 2009 9:37 AM in Graphics & Displays Share kjohnson1 January 4, 2009 5:55:33 AM So I bought a Sapphire 4870 a few months ago, its supposed to be clocked at 1800 mhz but in CCC it say that its only clocked at 900 mhz. Does this mean that my card is underclocked? More about : card underclocked foolycooly January 4, 2009 5:57:07 AM Are sure that's not just the idle speed? (If that exists...I notice on my CCC that the gpu and memory clock speeds are low when i'm not gaming/doing graphics intensive things) megamanx00 January 4, 2009 6:10:49 AM If you're referring to the memory speed it's 900MHZ (3600MHZ effective). As for the GPU speed I belive it's 750MHZ. Of course, when the card is not under load it down clocks itself to much lower speeds.

Wrecks January 4, 2009 9:37:34 AM Many numbers fly around. Some people use core values, some include multiplyers. It can be confusing. One needs to be very specific when identifying a clock / bus speed. As was mentioned, think DDR in this case. Can't find your answer ? Ask !
