There isn't a separate PAE kernel for i386/i686 anymore as with c6, PAE is an install requirement. -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77
I cut out the text of dmidecode that weren't necessary for the point: On Mon, Sep 08, 2014 at 01:52:43PM -0400, Bob Metelsky wrote:> dime910 /home/robert :( # dmidecode -t 17 > # dmidecode 2.12 > SMBIOS 2.3 present. > > Handle 0x1100, DMI type 17, 27 bytes > Memory Device > Locator: DIMM_1 > Part Number: 64T256020EU2.5C2 > > Handle 0x1101, DMI type 17, 27 bytes > Memory Device > Locator: DIMM_3 > Part Number: CM2X2048-6400C5 > > Handle 0x1102, DMI type 17, 27 bytes > Memory Device > Locator: DIMM_2 > Part Number: CM2X2048-6400C5 > > Handle 0x1103, DMI type 17, 27 bytes > Memory Device > Locator: DIMM_4 > Part Number: 64T256020EU2.5C2I couldn't find the Dell Service Manual for a 'Dell 770' but I was looking at the Service Manual for the Optiplex 760, and I saw that the way that the modules are paired isn't obvious. It looks like you've got 2 2G memory modules from 64T256020EU2.5C2 (Kingston?) and 2 2GB modules from CM2X2048-6400C5 (Corsair?). I suggest finding your service manual, and make sure that the modules are placed in the DIMM slots and the same vendor RAM is paired with its partner. It sounds to me like there might just be something weird going on with how the memory is installed. I'm assuming you don't have an artificial limit in the kernel command line or anything obvious like that. -- Jonathan Billings <billings at negate.org>

Accoding to http://www.dell.com/downloads/emea/products/pvaul/77XN.pdf It does support only 3GB of Ram. Can you please post a complete output of dmidecode. It may very well be a case where the on-board chipset is limited to 4GB address space minus the PCI addres space that leaves only 3 - 3.5GB ofg Ram space
