i wanted to know if my dimension E 520's mother board can be upgraded from a dual core to a quad core ?
well sort off. I put a q6700 in my dell e520 and a q6600 also works so, yeah. The only quads u can use are q6700 and q6600 just make sure u have bios 2.4.0 I am currently using a q6700
thankz alot so how do i go about upgrading my bios
well you go to support in the dell website. then driver and downloads. put in your service tag. go to bios, download it and run it.
