Hi ,

First time poster...have recently built a Conroe system 6600 with the Asus P5B Deluxe MB. I am using the 4 sticks of the Corsair 6400C4 memory(compatible based on ASUS web site- QVL). When I use all 4, the bios only shows 3. I am also using VISTA which can utilize 16 GB. Since the bios only shows 3, that is what VISTA sees....when I run CPU-Z on it, it shows all 4 sticks. I have called ASUS, and they originally said that it used the 1 GB above 3, for different board resources...PCI-E and so on. When I spoke to a different tech, they said the other tech was mistaken since the board can use 8 GB, and it would only use the "8th" GB of memory for this function. Since VISTA uses almost 1GB just to load on my system...I really wanted to be able to use the entire 4 GB. Don't know if this is a problem with just the ASUS P5B Dlx board, or was common to all 965 chipsets. Any help would be appreciated. Thanks!
Regards
Bill

Your choices:
1) WinXP Pro (32-bit) w/SP1 (not SP2)
2) WinXP x64
3) Windows Server 2003 (any flavor)

Set the Memory Remap feature on the Chipset page to Enabled.

Should solve the problem :)

P5B needs a memory hole remap feature to work with less than 8GB? lame....

Thanks for the replies....I did enable the memory remap feature which then showed 4 GB in BIOS, however the VISTA OS now shows 2 GB rather than 3GB it showed when the remap was disabled, and the BIOS showed 3...doesnt make sense.....any suggestions?....do I need to set something else in addition to enabling the memory remap?

are you using the 32bit version of vista? Maybe its just like xp were the 32bit version can only recognize 3gb. I dont know what that remaping options is but it has never allowed 32bit windows to see 4gb for me.

Sounds like Vista bug. Bios 0507 I presume? Vista for me showed 4GB with remap here.

What Vista build are you running?

5472 worked fine for me in 64bit with 4GB. But 64 or 32bit doesnt matter really due to PAE.
