Re: [coreboot] PAE status/ 8Gb of ram on X60 - coreboot

7 Jul 2014

Charles, just checking, you know the deal, right? Room at the top of the
physical address space is saved off for PCI. Hence memory in that range is
not addressable.

Chips that could hoist memory in the, e.g., 3g-4g range up above 4G have
been around since before the i945. Anybody know for sure that the i945 can
or can not do this? I"m not familiar enough with it.

  Hello

 So I took 2x 4Gb, and I do confirm that only ~3Gb can be used.

 Thanks

  I am wondering if there any limitation with
coreboot on using say 2x
 4Gb RAM sticks and a linux kernel with PAE enabled? 
 as far as I know, the Intel 945 chipset has a hard limit of a total 4 GB
 RAM.

  Is anyone using such a setup? 
 No that I know of. I only heard of 4 GB setups, where also not all 4 GB
 can be used.

 Thanks,
