according to Geoff Chappel", Microsoft may limit 32-bit versions of Windows to 4GB as a matter of its licensing policy

This was finally confirmed by Rusonnovich with Internals 6. 6th Edition came out in 2 parts; Book 1 & Book 2. Book 2 contains a fair bit of undocumented info not found elsewhere.

Page 320/321 lists physical memory support for all Windows versions, as on MSDN, AND the limiting factors, which are: "Licensing on 64-bit; licensing, hardware support, and driver compatibility on 32-bit" p320

problematic client driver ecosystem led to the decision for client editions to ignore physical memory that resides above 4 GB', even though they can theoretically address it p321

Exactly as Geoff Chappell said...:) It wasn't much of a secret tbh because AMD64 platforms running XP already made great use of 4-8GB RAM: No pagefile required. :) Great for servers.

Coming from Managed Services (Deployment), published material often proves more reliable than say MSDN libraries which can be rather ambiguous.......

No idea how to include a link to source which is Microsoft Windows Internals (6th Edition), Part 2, pages 320 & 321, As a wiki newbie so I apologise in advance for breaking any rules. :)

I saw some discussion also over absolute maximum RAM limits allowed by Microsoft...? The official maximum is 2TB, the limit doesn’t come from any implementation or hardware limitation, but because Microsoft will support only configurations it can test. The largest tested and supported memory configuration is currently 2TB. — Preceding unsigned comment added by 115.188.27.154 (talk) 18:53, 14 July 2016 (UTC)

"offset within page" does not come from the page-table entry

The phrase should surely be . — Preceding unsigned comment added by 83.218.4.174 (talk) 23:56, 12 October 2016 (UTC)

You are of course correct - and nice catch, that's been on the page for a long time. You can of course make the change yourself if you want. Be WP:BOLD ! Jeh (talk) 03:08, 13 October 2016 (UTC)

Why this British governed guy are welcome to change, why I cannot? Just because of the geolocation of my IPs, just because of Jeh dislike China. So this guy always messed up articles even though my suggestions are correct! So readers from China, please take care of this guy, Jeh. He might possibly attack you after he realise you come from China! ---Aaron Janagewen — Preceding unsigned comment added by Welcomejeh (talk • contribs) 04:24, 13 October 2016 (UTC)
