8gb showing as 3gb Asus P5Q

Ringlen · 3 Mar 2009 at 21:05

Hi,
I've got 64bit vista business sp1 and an Asus P5Q with 8gb OCZ reaper RAM installed.

it shows up as 8gb during boot, and when i right click my computer and press properties it says 8gb memory.

However, dxdiag shows up as 3326mb and the performance tab in task manager only reads 4gb

Any ideas or is this normal?

What operating system do you hae? Is it 32-bit or 64-bit? 32-bit OS's only support around 3.3GB

Read the 1st thing he said...

What does the Memory tab of CPU-Z sya?

If you are running Vista64 then you should be able to see 8GB in both task manager and dxdiag.

The amount of memory your machine is showing would point towards a 32-bit OS. What does it say under system type when you select properties after right clicking My Computer?

it is definatly 64bit vista

cpu-z shows 3328mb yet recognises all 4 2gb sticks (if im understanding what im reading)

Have you enabled the memory remapping in the BIOS?

What does it say when you go to, Contol panel>system?
should give processor and its speed, the ram, and the os

I'd remove a couple of sticks and reboot. Check what's registered. Then replace them and reboot again - might just give it enough of a kick to 'see' them? Used to get probs with a lot of Dell's at work like that, normally solved with reseating the ram... it's worth a try.

thanks ill try that now =]

Took a look at the memory remapping again, it was enabled. I disabled it to see the difference, and cpu-z would now recognise all 8gb, but task manager performance monitor still only sees 3gb
