Intel 980x 12GB only showing up as 8GB

[spiritguardian1]

Hello everyone,
I have found tons of forums on this exact issue, but none have solved my problem. I installed 12GB of DDR3 1600 into my new machine, but unfortunately, it is only seeing 8GB in both bios and in windows. However, each stick of ram works and each memory slot on the board works (tested). This makes me sure it is the timings. I set the timings to my ram suggested setting, but I have had no luck with that.

Clearly everyone here is well versed in how to get motherboards and ram playing nice with each other. I will post my system parts in my signature. I don't care about overclocking because prior to adding the extra 6GBs of ram, I was running very well with the CPU already with no issues. I only bought the extra 6GBs because I wanted to make sure I got matching sets for future needs instead of having to mismatch.

So if someone can provide me with exactly what I need to change in my bios to make my system run correctly with Triple Channel instead of its current dual channel according to CPUId and running more than 800Mhz (also CPUId).

Thanks,
~Spirit

Take a look at this guide:

http://i4memory.com/ramdetect

You will want to check whether the memory is being physically detected in CPUID. One module may be defective, or one slot, causing the system to operate in dual channel. Swapping them around should help isolate this problem.

I have tried CPUID, and all memory is showing up in it. I have done most of the stuff on that link you posted. I am also working in another forum on this problem, but I am hoping you all can help me resolve this issue asap because I need my computer running staple and at the speed it was before I installed the other ram. I don't plan to remove the new ram either, completely wasting the 200 I spent on the 2nd set.

Link to my other Forum discussion if that helps: http://i4memory.com/f83/intel-980x-1...06/#post131855

Here is some information I posted to the other forum, maybe you can help figure out where my issue is. I suspect it is timings of the memory.

Try setting QPI/DRAM Voltage manually at 1.30V and see if that helps. If not, I would suggest sending the memory in for new replacements to see if another kit will have diffferent results.
