Hi there! Well, I have to admit that I found this most surprising. I am running Centos5.5 on a Del Optiplex GX 620 that I''ve been using as a xen server. I had been running it with 4gb of ram which is quite a bit but thought that this machine would SCREAM with an additional 4 gb that I was able to grab out of an identical machine that my wife made me shut down. :) But when I put the ram into the two darker slots (this machine has 4 slots - two white and two dark brown) I get on bootup and after selecting the Xen Kernel (centOS (2.6.18-194.11.3.ex5xen): (XEN) System Ram: 7414MB (7592088kb) (XEN) Xen heap: 9MB (9836kb) (XEN) Domain heap initialised: DMA with 32 bits (XEN) PAE enabled, limit: 16 GB (XEN) (XEN) ************************************************* (XEN) Panic on CPU 0: (XEN) Not enough memory to bootstrap Xen. (XEN) ************************************************* (XEN) (XEN) Reboot in five seconds then a bunch of memory addresses in hex. Bump it back down to 4gb and all is well. I''d be curious to hear some backstory from anyone willing to provide it! :) _______________________________________________ Xen-community mailing list Xen-community@lists.xensource.com http://lists.xensource.com/mailman/listinfo/xen-community

Did you try the new 4GB stick only? Todd _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
