Re: [PLUG] System Sees only Half Installed RAM [RESOLVED]

If the BIOS isn't seeing all the RAM, then I suspect a hardware issue that a BIOS update will not resolve. Russell, Wes, et al.: After I sent the message (of course!) I realized that I needed to check the BIOS setup. Apparently, one of the memory modules was not fully seated, so I took them both out, swapped them (which would tell me if one was bad), and carefully re-inserted them. The system now sees all 8G.

Don't sweat it. I'll bet that nearly every one of us has done the same a time or two. :) Russell Johnson r...@dimstar.net ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

With this newest version the system is supposed to recognize and use all 8G of installed memory. But, it still sees only 4G. By the system do you mean the bios, or the OS (Linux, presumably?)? If it's the former, then there may be a hardware problem, if it's the later, then you probably just need to install a different kernel. In my experience, the SMP kernels shipped with common distros also have the proper support for seeing 4gb of ram, but others on this list know the details much better than I do. --Rogan Does anyone here have thoughts on what I should do to make all RAM visible and usable? If not, I call Dell tech support on Monday.

Another reason may be you need to switch pairs around. Another reason maybe bad memory. Have you been able to run a memory checker? It might ignore the BIOS. -- Ken Stephens, SV Aventura, Portland, OR ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
