Windows 7: 4 out of 6 ram usable on w7 x64 please help

Hi there fellas, i got this problem with 6g installed ram but windows only shows 4 (i can see 6 when i check with cpuz) the ram is all new and i have also checked them all for errors. I find this annoying since some games freez up or give me blue screen due to memory running out : S



I link my dxdiag and hopefully some one smart can see what is wrong : )

Hello there.Take a look this tutorial:
Memory - Set Maximum Amount Used by Windows 7

i tried following that tutorial but i had no luck at all : / there must be something else

Just to be sure that your sticks and sockets are working. Install Everest and go to Computer->Summary,scroll down and you'll see
This is from my computer,check yours.
Also how much ram is showed is BIOS? If there is showed 4GB,there may be problem with your memory.
It will be good to check your ram with Memtest.

DMI Total / Free Memory Sockets 6 / 4 for me.

I have run memtest for several nights in different periods to check em and their flawless as they should be since they are spanking new : /

Oh also im not sure how many showing up in bios but as said in the original post i can see that 6 is installed with programs such as "cpuz" and similar

ALSO found this also stating 6g dimms : /
Motherboard - Asus Rampage II Gene (1 PCI, 1 PCI-E x4, 2 PCI-E x16, 6 DDR3 DIMM, Audio, Dual Gigabit LAN, IEEE-1394)

Hm... If CPU-Z sayz that there are 6GB of ram installed there should be 6. What's one dimm size? 1GB?
If you have 4 used slots,combination can be 2GB+2GB+1GB+1GB. Or you have 6 dimms of 1GB. (so 2 of them are not working) ?
Can you see in your motherboard,are there really 2 slots free ?

there are 6 slots, i use 3 of them, its 2, 2, 2 (also i have put them in in the slots told by the handbook that came with the motherboard for my configuration

Here.. Total = 6 , Free = 4.
You say that are using 3 slots(2+2+2). Windows is saying that you are using only 2.(6 total - 4 free = 2 slots) . So it seems to be a problem with one of the dimms.
To find out the broken one,follow this:
1. Pull out one of them,and boot Windows to see if there is 4GB ram installed.
- If there is 4,that's ok. The two remainning dimm's are working.
2. Install that dimm again(that one that you pulled out before),but now pull out another one from two that stayed.
- Boot Windows to see how much ram is installed. If there is only 2GB of ram,that means that the problem is with that dimm.

problem is memtest dosnt say 1 of them is broken (also i just changed them cause i had the same problem with another set of dims) my guess is that its the slot its in? but the wierd thing is that if something is physically broken then why can i eve detect it with some programs : S

If you have three memory modules, in that board they need to be in slots DIMM A1, B1, and C1. Check the memory slot alpha/numbers in your mobo manual under Recommended memory configuration for better performance.
