SharePoint Event ID 2138

We have installed SharePoint 2010 RTM on three serevrs:
- Two servers acting as a Web Servers (10 GB RAM, 40 GB for C drive and 80 GB on D drive)
- One server acting as an Application Server ( 10 GB RAM, 40 GB for C drive and 80 GB on D drive)
- One SQL 2008 server.

After configuring the farm, now we are getting the following even ID on all servers:

Description:
The SharePoint Health Analyzer detected a condition requiring your attention.  Drives are at risk of running out of free space.
Available drive space is less than five times the value of physical memory. This is dangerous because it does not provide enough room for a full memory dump with continued operation. It also could cause problems with the Virtual Memory swap file:  (ComputerName - C:\).
Examine the failing servers and delete old logs or free space on the drives. For more information about this rule, see "http://go.microsoft.com/fwlink/?LinkID=142688".


The previous error indicate that we need to increase the space on C drive. Now, I have installed SharePoint on D drive since I wanted to dedicate the whole drive to SharePoint. Just a reminder this is the RTM installation and since there are no SharePoint 2010 RTM documents, I have used the Beta documents which states " Maintain twice as much free space as you have RAM for production environment"

I am not sure if I can safely ignore the warning since my SharePoint resides on a separate drive. For now I think I will wait and see....I hope Microsoft will start revising their documents before the official release date for SharePoint 2010.
