Ok, got in all my parts and finally had time to start the build. I have an ASUS Sabertooth 990FX mated to an AMD FX8150, Sapphire 6950 2GB DiRT3 Ed., and Mushkin 2 x 8GB 1600MHz ram sticks. The rig boots fine, and in BIOS settings it only sees 8GB's, not 16GB's. It sees both sticks, just not together, and it sees 1 stick no matter the slot. Now, the manual says it supports 1600MHz ram and it supports up to 32GB (which is 4 x 8GB). So why wont it see the other stick???

[Oderint dum Metuant]

The board is detecting both sticks.

What OS are you running? if its Windows 7 Home Basic then there is an 8GB limit on 64bit

And when you having both sticks in, you have them in the correct sockets? If you think of your RAM sockets as A,B,C,D you should have them in A and C

I had a quick look at http://uk.asus.com/M...OOTH_990FX/#MSL and your ram config seems not on the qualified vendor list document.

I have the same board, and it is a bit picky with ram. I had bought amd performance ed ram (patriot) and get all sorts of weird issues. Swapped for corsair vengance, all good.

I think that in the manual, while it states 32 gb max ram, it is also says that 4gb per stick is the recommended max stick size, but I could be very wrong on this one.

are they paired mem or not ?... if they arnt paired you need to move one to another slot =X that might be whats causeing the problem

also im not sure but you might wanna check in the manuel to see if the board can have more than one stick of 1600mem in =X i think u can useualy only have one =X unless the board says you can have more =X

a) 99.9% of the OP suggests us that he has got paired sticks.

b ) what? As long as you keep speed consistent between at least pairs, you can have anything in between 1067-2000mhz.

edit stupid smiley. AGAIN

yes yes i know this already =.=i do build my own pcs after all

but some mbs wont let you have more than 1dim at 1600 (or other higher rates).... and as you said the sabertooth is kinda picky with what it likes .. at least thats the jist of what i saw in the search i did =X

and whats wront with silly smileys ?=3

One of my rigs is running the Sabertooth 990FX, I have zero issues with RAM in configs of "ALL" DIMMs filled with Corsair Dominator 1600 MHZ 8gb... and with More than 8gb Corsair Dominator running with two different Corsair Dominator kits 1600 and 1866 mixed with timings set and the 1600 overclocked to match the 1866 kit and timings of (9-9-9-24) for a total of 12gb RAM and other config at 16gb of RAM... Also ran similar configs with G-Skill sniper 2133 at set speed to 1866 and overclocked to 2000 with no issues, also ran these configs on a Crosshair V 990FX.
.
I have a freind that runs Mushkin RAM, and he cannot get it to run specified timings or speed (even overclocked), i'm not saying Mushkin is horrible RAM, but this is eerily similar to his issues... With it "NOT" being on the QVL, I would start there..
Asus boards aren't really that picky with RAM, I have ran all kinds of stupid configs, of RAM together (different speeds oc to match, different brands) with different results, but sometimes they will not run well with RAM that is "NOT" on the QVL list....
.
Trying to save $30.00 on a build has been the cause of many a problem for friends and customers alike in "MY" experience..
Not that it means anything....

just out of curiousity... did you accidentally set your ram to ganged mode?

[Quinn Allard]

Just to update. We couldn't get the board to see both 8GB sticks no matter what we did, downclock, overclock, bios settings, it didn't matter. So we went with 1 Mushkin 8GB stick, and 2 Kingston 4GB sticks. It read it all and is reading all 16GB's. So......we stuck with that.

Interesting... Will make note of this for future reference.

I have a similar problem. Same board with fx-8350 and 2x 8GB 1866 Corsair vengeance CL9. Memtest gives every time alarm and the system crashes from time to time.
So far only one answer from Asus, powersupply to low.... but it is not correct. I changed already the ram, board and chip, but still memtest errors. Hopefully, my vendor will exchange the ram for me another time... *crossed fingers*

I will try odinsfist build with dominator and 2x 8GB Dominator 1600, hope it will work.

But which Dominator did you use? XMS or Platinum and CL9, CL10, CL11???

Maybe stupid pointer.

But have you tried both mem sticks alone to see if other one is faulty?
And have you tested your board with other mem sticks to see if memory slots are working properly?

Also, if that memory is not on the qualified vendor list, your board might not support it, so you would have to change mem sticks to other brand, preferably to something supported by qualified vendor list.

As last note, have you upgraded your bios?

[Badconduct]

FX990 with G-skill 1866ghz 2x 8G sticks.
No issues.

If you "just" swapped your RAM on your previous BIOS settings, use the MEMCHECK start button "Top right, turns red on boot" to launch into BIOS and check the RAM.

Make sure they are paired in the light gray slots.

Check 1 stick at a time.

Reset BIOS to default.

Update BIOS, there's an update as recent at Jan 31.

Don't mix your DDR3 RAM.

Use kit-pairs.
