Aurora R11, RAM failure, unusual issue

Not heard of that but, auroras are not validated for 4x8GB configurations 

As already pointed out, 4 x 8 GB is not a validated configuration. Therefore, it might or might not work:

Validated memory configurations R11 

Also, it's not clear from your post exactly what the memory was that you added. The only memory validated for the R11 is: R11 validated memory 

You cannot mix and match memory sticks from different manufacturers, or different parts numbers. 

These boards are very picky when it comes to memory support, and it's always recommended to only use the DELL validated memory, in their validated configurations. Any aftermarket memory might or might not work well.

Are you on BIOS 1.0.7?  If yes, boot up with just one stick of OEM RAM. Restart several times to ensure stability.  If all is fine, and you are on BIOS 1.0.7, downflash to the prior version by clicking the .exe here:

Then please let us know if this solves your issue.

OMG please tell me you solved this. Having exact same scenario with my R11 but I upgraded ram to 4*32gb Cosair Vengeance. Was working fine for 2 months but suddenly dead and blinking yellow light 4 time every boot with 3 or 4 sticks in it. Called dell support and thought its the motherboard and got replaced but same problem consist. Then thought it the ram problem but each pair works fine by them self. Now I can only boot up and play with 64gb and leaving the other pair alone and have no idea what i should do...

It is likely some change related to a change in bios version. If it is not factory OEM ram it is going to be difficult to fix this.

I too had my system running fine for almost a year with the OEM and a retail Kingston Hyper X in the same channel with XMP Enabled, then after a Bios Upgrade the dreaded flashing yellow I was working around the issue by having the chips in separate channels, and thankfully someone just dumped a 3 pack of the retail 8GB chips that matched my additional one on an online auction for less than $50 so I am now happily running in 4X8 for 2 weeks now, unfortunately I know if I have a problem I am going to be SOL since it is not a validated configuration.

These systems are ridiculously sensitive on matched memory and specific memory at that, unlike systems in the past that would tune down to the slowest stick in the group, these just will not post past bios. Then on top of it the OEM memory Kingston Hyper X at same MHz ratings are different than the retail ones, and then some ridiculousness about 4X8 not being an officially supported configuration.  I am not even sure who to be mad at Dell for trying to sell OEM Only memory at 2-3X what similar chips sell for online elsewhere or Kingston manufacturing subtle differences that prevent mixing OEM and Retail chips in the same channel. The fact that I can insert one chip either OEM or Retail and pass every memory test in the bios, put them in separate channels and pass every test, but cannot post if they are in the same channel is extremely frustrating. Thankfully people on this forum but this experience so far makes me want to go back to building my own PCs. 

Kingston!  I create 4 heatsinks with a 0.2 tolerance pull on, push off, its amazing DRAM, i compare with 3 DRAM banks 11 years ago with a GTX 590, those banks where standard 1800 mhz and fully heatsinks, now we have a R 13 and no heatsink is found on those 2 banks 32v GB dual R 4400, so i create that at my own, with a internal temp recording it close to 10-14 degrees below, intresting, isnt it?

I'm listen to Helstar, nosferatu the whole album from 1982 and read about that 

DRAM here, open your lovely Alienware and take off and push back DRAM, no blabla.

Take off phisically and push back DRAM will resolve problems many issues,its a little forgotten old resolve from my generation back 14  years ago, but its a strong tip and still stand this day

Why you talk about DRAM frustating and Bios?> What is the compare with those 2? simply forget Bios, and reset your DRAM, and dual channel = dual channel, you cant messure the seperate, My R 13 didnt have Kingston btw...thats passed a long time ago, and its not ridiculousness about whatever your mem is one a specific AW Motherboard, put them in separate channels? how? what is your configuration?

When you want test dram and/or ,otherboard, make sure you know where the north and southbridge are, from that location you put in dram into the righ slot^^\

[ Edit ] When its west from both of them , you start with first slot left, so 1-3-2-4

very usefull when you planned to buy more dram^^

You cant simply put in dram into a slot you think its the right.

Take a picture from originally factory set up^^ then mess with more banks.

3-1-4-2 . . . but whatever

Does anyone have a solution? Please help.

What is the problem you are experiencing?

I just bought new ram from Dell that is compatible for my Alienware aurora r11. I bought another 8gb ram, making 16gb in total. First, when installing the ram, i have to force it in despite videos telling me I shouldn’t haven’t to. Thinking that Dell recommends me this product and says it’s compatible for this PC, I shouldn’t have to force it. However, there was a time where I was able to get the ram into the slot. I placed it in the slot with the white clips. After closing up the PC, I turn it on to where the light blinks yellow four times and shuts down then repeats. On, blink four times, shut down. Reboots. On, blink four times, shut down. Reboots. And so on. I seriously do not know what the problem is. It fits the compatibility with the PC, straight from Dell, recommended by Dell, so there is no reason that this shouldn’t work, yet here I am struggling. What do I do?
