We use such a machine here in production, with the caveat that an older coreboot revision is used. That being said, keep the four slots closest to CPU1 unpopulated (i.e. fill all 8 slots on CPU0, and the 4 farthest from CPU1) and you should have no problems reaching 192GB. Those particular slots appear to have physical routing layer issues caused by marginal design, and thus far we have had no reason to even attempt a workaround given the high cost involved. As always, if someone else would like to try to work around the corruption issues, they are more than welcome. Populating all four slots closest to CPU1 with large ECC registered DIMMs is a surefire way to recreate the instability -- note a training failure is not common, the main issue is that the marginal routing causes severe memory corruption when the BKDG-recommended algorithms are used. - -- Timothy Pearson Raptor Engineering +1 (415) 727-8645 (direct line) +1 (512) 690-0200 (switchboard) https://www.raptorengineering.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJYi7zeAAoJEK+E3vEXDOFbmOEH/itJEw/sz6Dq4LFSXQqMEKPS cAY7/YoP8hEfsHBjP+buyKyRyj7Q9988dhrgd4db/cU4QWD5XACYTUTZJMKcnpav /MwAWpjxOD9IPginTRCUKwvDhhdnt8IQIe2cNV4ujj57nvkOpgPhrM8eR//11HP+ qtqc7EXUR9RmxIP/cn2GJ7MWZ8+DqJbdmdeTqdF9xo6YkQ2RceYyFbofEoONBN9R nQgz6wysrgH/jZkhTcwR23TZCcJcx6DV7gEuwHj5K/9iqXWqX+gAr8bMB8rii9HA zqCYWp1Ihm+hHBfGvxZ4niy5yQyU2Dq+80CjtkN8qiG0c7ThHlk84ZRo5sQDgjM= =L5ST -----END PGP SIGNATURE----- -- coreboot mailing list: [email protected] https://www.coreboot.org/mailman/listinfo/coreboot
