HP Envy does not detect all RAM in win7 x64

post #1 of 2
Thread Starter 
I've been searching the forums for a solution to this and I don't know what to do:

I have an HP envy running windows 7 x64, and it is only detecting half the 8Gb ram I have installed.

OS NameMicrosoft Windows 7 Professional
Version6.1.7601 Service Pack 1 Build 7601
Other OS Description Not Available
OS ManufacturerMicrosoft Corporation
System ManufacturerHewlett-Packard
System ModelHP ENVY 17 Notebook PC
System Typex64-based PC
ProcessorIntel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz, 1600 Mhz, 4 Core(s), 8 Logical Processor(s)
BIOS Version/DateHewlett-Packard F.1D, 07/04/2011
SMBIOS Version2.6
Windows DirectoryC:\\Windows
System DirectoryC:\\Windows\\system32


so according to the MOBO spec, I could have 8Gb ram
I bought 2x 4GB Corsair memory
I have made sure that the memory chips are seated correctly
BIOS detects that there is 8GB of RAM installed
here is the system report on the RAM:


Installed Physical Memory (RAM)8.00 GB
Total Physical Memory3.93 GB
Available Physical Memory2.22 GB


basically my system is detecting but not using one of the RAM chips
I don't have a setting in BIOS to map memory
I can't get to the motherboard to adjust any jumper/ voltage settings
CPU-Z shows both chips installed and working
I am running windows 64bit
been into MSCONFIG and maximum memory is unchecked

..and this is where all my efforts have now run out. so I don't get it. 8Gb installed, 4Gb available ? what do you think - dodgy RAM chip?

any ideas?

The HP service manual lists a dual rank module as replacement part:
599092-001

Is your crucial memory dual rank or quad rank?
