What the heck are you talking about? All the ram adjustments are done in the bios and you don't need to jump anything for it. If your system is from a big oem manufacturer you may be limited on memory settings. If its a custom build then most likely you can adjust your settings.
my computer is totally compatible ive checked it out but the problem is I have no display, internal video, no beeps monitor is good im thinking i have bad ram, every thing comes on and no dice
