Hello everyone!
I bought 24GB of RAM for my computer and i can only see 16 GB. I did see 24GB for a day or two. But then it disappeared again. What can be the problem?

Motherboard: MSI Big Bang X-Power
Processor: Intel Core i7 980X
RAM: Corsair XMS3 1600 (4GBx6)

Any help regarding this would be appreciated!

first boot with each stick of ram alone and run memtest and see if all modules are ok.

if all ram sticks are fine and yet you dont see all the capacity try increasing the dram voltage a bit. what are the specs of your ram can you link to its spec page ?

do not worry list will go long of the people coming drooling around just hearing about it LOL

also people have already suggested what is needed to check. I am guessing one RAM already got caput hahahaaa

@asingh you also know it wont even show 16 GB on 32 bit :p

clr CMOS and try again also BTW even 8GB of RAM is waste of money unless u running a supercomputer with teslas inside :p but its gr8 for showoff , whats the speed and timing of ur rams ?

Hello again!
Thanks for the pretty much instant replies!

I think there must be a problem with the DIMM slots.
If i load a single stick into the DIMM 0, it won't boot.
Then putting 1 more into the DIMM 1 shows 4 GB.
Adding one more into DIMM2 shows 8GB
Adding into DIMM 3 has no effect and it shows 8GB
Adding into the DIMM 4 shows 12GB
Adding into DIMM 5 slot shows 16GB.

I guess there's something wrong with the DIMM 0 & DIMM3 slots.

HERE is the spec of my RAM:
Newegg.com - CORSAIR XMS 4GB 240-Pin DDR3 SDRAM DDR3 1600 Desktop Memory Model CMX4GX3M1A1600C9

For the rest of your queries, i'm a freelance post-producer for videos. So i do a lot of animation, rendering and editing.

Did i mention that i also have a GTX580? Two render nodes with AMD 1090T &12G? 22TB total storage across the entire setup?? :twisted::grin:
Okay, now i'm just showing off. Please still help me!

I thought you would mention something like quadro6000 which has 6gb ddr5 memory etc. Since that is the one suited for such a task. But gtx580?

I actually was expecting that. Well there are a couple of reasons.

1. The actual GPU doesn't really speed up the render. It just makes viewing complex and more detailed models a lot faster and smoother. Rendering is almost entirely CPU based.

2. CUDA. Almost everything uses it. The newer render engines (VRay RT, iray), the Mercury Playback Engine in Premiere Pro CS5. Don't know about VRay 2.0.
Thhe GTX 580 has a lot more CUDA cores than the Quadro 6000 (Which costs about 10 times as much). So it was an easy choice for me.

Besides i do more video work and i need better performance in P.Pro. If i ever need to work on a complex model, i can always buy a quadro 4000 or so.

Getting back to my question.

I upped the DRAM voltage to the specified 1.65V. Still nothing.

you need your mobo checked DIMM slots not working properly is inference you got use that inference for RMA of motherboard whatever you do if the 2 DIMM slots have gone dead they wont come up alive.

Highly probable what Acewin, is saying is correct. You motherboard supports 800/1066/1333/1600/1800/2133 RAM speed, and your XMS3's are 1600 CL9s. You can do this...before sending for RMA -- figure out what to send for RMA.

1. Try all your DIMMs one-by-one on another DDR3 board. Just plug them in the first slot and see that the computer boots fine. Painful to do 6x times but will help. If you catch the bad DIMM here then the board is fine.

2. Try to load your board DIMM docks with the same color. Fill only BLUE or fill only BLACK and check.

Let us know.
