Asus Crosshair and 16gbs of RAM... Help?

post #1 of 12
Thread Starter 
Hello all first post here.

Problem:

My Asus Croshair IV Formula does not recognize all 16 gigs of RAM?

Possible solutions tried:

I have flashed to the latest BIOS rev. Still no go.

Updated everything I could think of. Still no go.

Re-seated the modules. Still no go.

Please note: I am not too familiar with any BIOS settings as I feel this may be the root cause to my problems... hopefully. Tinkering around in the BIOS is not one of my stronger traits for fear of mucking something up - so I call upon the forum gods here to show me the way.

Is there settings I need to be aware of and/or change so these 16 gigs show up? Do I need to up my voltage / timings / or something else - if so how and where are these settings in the BIOS?

System specs:

MS Windows 7 Home Premium 64-bit

Crosshair IV Formula (AM3) with BIOS v.1102 (8/24/10)

AMD Phenom II X6 1090T

AMD Radeon HD 6970 Series

As of now my RAM shows: 4.0GB Single-Channel DDR3 @ 668MHz (9-9-9-24) - when I had all 16gigs in, it only showed 8????


Please help... and any assistance in this matter would be FULLY appreciated!

Regards.

Put 2 sticks only on one channel. Then put 2 sticks only on the other channel.
(Keep in mind each channel is spaced as such:
| . | . then
. | . |

If it only posts on one of those configurations it's a toss up between the IMC (located within the CPU) and the board itself. See if you can borrow an AM3 cpu from somewhere to test.

Also try Ganged mode in BIOS.

Thank you for the lightning fast response!

So If i read this correctly, place the first two paired sticks in slot 1 and 3 - and the other paired sticks in slots 2 and 4?

Is this correct?

I'd put a stick in 1 and 3.
If it posts, use the same sticks, and move them to 2 and 4, and try to POST.

If it doesn't post, try the other sticks, to isolate any problems with the RAM itself.
If you wanted to completely isolate RAM only issues, run Memtest 86+ with one stick in the PC at a time.

To me it sounds like problems with one of the RAM channels.
If you had all 4 sticks in and one channel was functional, you'd only appear to have 8 GB.
Same scenario when you added 2 sticks on separate channels and the total capacity was only 4 GB.

@ Beers - Thank you for the exceptional advice! I will give it a try right now and attempt to narrow down the problem.

@ AMOCO - I got an amazing deal, a bro deal from a good friend. I already had 8GBS and figured what the heck! ;-)

GBS is Gigabytes per second, it's just GB you mean.

All i can suggest is what beers said, that's pretty much your go-to soloution when having RAM problems.

@beers - Thank you sooo much, I have now resolveded the issue. I removed the original 2 sticks in 1/3 and moved them to 2/4 - rig fired right up and no issues.

I then put the two new sticks in 1/3 crossed my fingers and BOOM - rig fired right up and now properly shows the full 16gb.


Here is the end results:
