Who words these questions.
You don't need pae for 4Gb. You only need it if you use more than 4Gb.
At 4Gb the /3GB switch can be used.

I agree.

At what memory point must you set the /PAE ...

The important word is must. SQL will utilize 4GB without /PAE. Only at 8GB must /PAE be set otherwise SQL will only use 4GB.

Far away is close at hand in the images of elsewhere.

I do agree. 8GB is the right answer based on the wording of the question. Will you guys at sqlservercentral correct this?

From the same article "The extra layer of translation is what provides access to physical memory beyond 4 GB."

I agree you can use /PAE with 4GB, however I don't see the benefit. 2K is still going to use 2GB leaving the rest for applications. I would use /3GB with 4 GB and a combination of /3GB and /PAE for above 4GB.

However, don't use /3GB if you have 16GB or greater (DataCenter Edition).

I have to agree on this one the answer should be 8gb. From BOL

"To enable Windows 2000 Advanced Server or Windows 2000 Datacenter Server to support more than 4 GB of physical memory, you must add the /pae parameter to the boot.ini file"

The emphasize to show that the /pae parameter is for MORE than 4gb not if using 4gb.

I know we are splitting hairs but the wording of the question could have been more clear.

For what it's worth: I answered this question (cause I've had to do this one) through the daily update newsletter.

My initial answer was going to be 8 because the question was worded "at what memory point" and 8 being greater than 4, the threshold.

When I switched to a browser (to confirm my answer) I realised the wording was different, and chose the "more than 4GB" answer.

Jolly confusing or what? Not just the wording, but consistency of wording!

I should have had a cup of coffee before answering this question!! I did not notice the difference in wording between the newsletter and the browser window for this question. So what was a correct answer the way the newsletter was written became an incorrect answer when I finally clicked "submit".

Kinda bummer since the answer is plain for all to read in BOL.

David Burrows SSC Guru Points: 65143 More actions · Answer 8

Since corrections have been made in the past I always check the answer I give in the newsletter is the same in the forum, maybe I missed this one but I am sure that is not the case, oh well that is life. I think in the future I'll ignore the newsletter and go straight to the forum for the question

(but not for the content eh! )

Who words these things? You don't need /PAE at 4GB.

Use of the /PAE switch in the Boot.ini and the AWE enable option in SQL Server allows SQL Server 2000 to utilize more than 4 GB memory. Without the /PAE switch SQL Server can only utilize up to 4 GB of memory

Though I "got this question right", I completely agree that clearer wording would be nice, eg, "Above what memory point..."

I'd like it if there was only a warning if there was an actual change in the question. Otherwise it's like crying wolf everytime. I too answered 8GB and then proceeded to answer the question without double-checking. Grrr.
