Asus P6T Deluxe, Only showing 4GB?

post #1 of 23
Thread Starter 
Of Course I Installed 64-bit OS...



Just last night we decided to clean the PC out and install the 128GB SSD Crucial M4 as my main drive, which by the way, is only 119 GB
which kind of sucks because per GB its expensive, and 9 GB of Lost space might prove to be disasterous fo rme in the long run with my games =(

Anyway, Booted up the system and noticed that my Memory is only showing as 4GB??

Very Strange, I know i have not made any changes to the memory, of course durring install i reverted all settings to stock.

At work now so when I get home I will remove the memory and reinstall them,

But I was wondering if anyone knew of something I might have done wrong that might be a quick fix =?

Always worth a question.

Thanks guys

in the BIOS theres a setting (or atleast on my ASUS motherboard there was..)
I believe its called something like Extended Memory Protection or something like that, you need to change the value from what it is, then it should show you the whole amount of RAM that you have installed in your computer.

Again, I cannot remember if this option was on or off, but whatever it is, try changing it and see if you get any results, I hope i've come to some help. thumb.gif

Did you install the 64-bit OS?

Check Bios and see what it says about your Ram.

4GB can be caused by poor contact between CPU contact pads and pins in socket. Make sure you tighten the heatsink evenly on to the CPU.
post #7 of 23
What QPI voltage are you running? I did a build recently for a friend using the P6T deluxe and installed 24Gb of ram (6 dimms). The board wouldn'r recognize all the ram until I increased the QPI from 1.10v to 1.25v (the system is also OCed). If you are running the ram at higher speeds, you will probsably just need QPI bump. Or it could be the CPU's contact to the socket pins. The memory controller is on chip, so this can be a likely cause as well.

Ohh Very Interesting, You think that over time, or when I had to move my case aroudn to clean it out with air compressor, that the Noctua possible flexed in a way that caused this issue ehh??

Thats just Crazy! I wonder where my long screw driver went.. Must fix this issue - So weird I never had this happen before.
Thanks for the idea, this could be the reason

The P6T Deluxe is notorious for incorrectly reading the total amount of memory you have installed, regardless of the settings you use (QPI, CPU socket pressure). Have you updated the BIOS? Also, what are your QPI voltage and memory voltage settings in the BIOS?
