I'm currently 'furbishing an HP 630 laptop running Windows 7 Pro Service Pack 1. It has two slots for RAM and uses type DD3L-128000S. Documentation states a maximum of 8 gigabytes supported, which should not be exceeded. It came with a 4gb stick and I put in another 8gb stick which I hoped would read as a 4gb module instead. Now it won't finish booting and system information says it can see all 12 gigabytes installed.
My Query; Is there a way to: A. Tweak the BIOS, MoBo or other settings to boot with all 12 gigs? B: Dumb it down so it can only read half the module and use 4gb? C: Take out the 4gb stick and use a single 8gb?
If it helps: Trying to boot up using only the 8gb module resulted in a BSOD of the Bad Pool Header variety. Trying to boot with both results in the Windows or Startup Menu appearing for a brief period of time followed by the laptop restarting.
