Hi Guys! its my second time posting hope you could help me. I'm having problem with my VC running only at x8 (bus interface). I've already check my mobo's bus interface support. It's x16 (max supported) So far I already uninstalled the ATI Catalyst and installed the latest one (11.9). My Mobo already has the latest bios base on the website. I also checked bios if there was any settting that can enable the x16 bus interface. No luck unfortunately. Hope you can give some other ways to maximize the usage of my VC. Here is my Specs: OS: Win7 Ultimate 64bit Mobo: EMX-MCP61P-AVL Proc: AMD Athlon II 240 x2(2.8Ghz) Mems: 2x2GB Kingston CL6 800MHz Vcard: Sapphire HD 5850 1GB HDD: WD Caviar Blue 320GB PSU: Hec Raptor 500watts Mon: Samsung T190 19" Case: Coolmaster Elite Black 430 I have attach my VC and Mobo pics. Thank you in advance.
