I think I would also run the memtest under the VM to make sure that the memory map is actually all reachable within Linux and doesn't mess anything up.

- Etheryte 8y agoAs far as I can tell, the author did run tests on the memory after finishing: > All I know is it passes my RAM tests.
- d33 8y agoI don't know much about kernel memory management, but if he was booting memtest86+ bare metal, I wouldn't be surprised if he wasn't triggering the same edge cases Linux would do - which is why I'd prefer to make the actual system try to allocate as much memory as possible, use it and see if the results are sane.
- drudru11 8y agoSimple - just run Chrome. It will consume memory like no tomorrow.
- dougg3 8y agoI'm the author of the blog post. My first time here on Hacker News...very cool that it was picked up! I did my memory testing inside of Linux using memtester. I honestly want to do more thorough testing at some point to prove that it's actually working okay. If some of the PCI hardware is still paying attention to that overlapped range, weird stuff could definitely happen.
