Wrong memory bus read on 2nd amd 7770 Tags: Radeon GPUs Memory AMD Bus Graphics Last response: January 25, 2013 1:15 PM in Graphics & Displays Share earvinarp January 24, 2013 6:42:27 PM Hello, I installed the second gpu via crossfire. It all seems fine but gpu-z shows the new gpu at 32 bit memory bus instead of 128. Is this a bad read by gpu-z or am I doing something wrong here? My mobo is a p8z77-v deluxe.

Now the read in GPU-Z is correct. So, that is solved. | Report abuse Reply to earvinarp Ask the community Post an answer Tom's Hardware>Forum>Graphics & Displays>Wrong memory bus read on 2nd amd 7770> Related ressources: ForumGTX 550ti vs AMD 7770 ForumNVIDIA GeForce GTX 560 2GB vs. AMD Radeon HD 7770 1GB ForumWhat's wrong with MSI Readon HD 7770 ?
