Replacing RAM in Alienware Aurora R4

Hi guys this is going to be long winded so if you wish to only read my problem skip to the next paragraph., I have an Alienware Aurora R4 built in 2013. I can post my service tag if needed although i imagine my warranty has expired. I am a huge Flight Simulator user and for those of you who know Microsoft Flight Simulator X it is very CPU and Memory intensive. I shoot for realism with my sim so about a year ago I added another Nvidia GTX 680 to my computer and my frame rate was better what wasnt quite the 30-35 fps I was looking for. So a couple moths ago I tried overclocking the processor further. The processor was stable at about 4.5 Ghz but it would crash eventualy. I came to the conclusion that i was RAM limited. So in the past week I have done my research and bought some new RAM. I know my motherboard supports a max of 32gb at 2133Mhz so I bought a 32 gb kit from Corsair. It is a 4x8gb Corsair Vengence pro DDR3 2400 Mhz. 

My problem is this: The computer will not POST when all 4 of the Corsair Sticks are installed. The computer turns on and all the fans and lights act like the computer is running normally but my monitors stay black. The only way I have been able to get the computer to run properly is if i install 3 of the Corsair sticks and 1 of the old Micron sticks. When I run it this way it clocks the RAM down to 1333Mhz and it recognizes all 28gb of RAM that are installed. I have tried setting the multipliers and voltages manually and i have also reset the BIOS multiple time via the CMOS. I contacted Corsair and they said it was a motherboard incompatibility and they said to contact Alienware. However, they had no explanation for why the 3 and 1 worked. Thus here I am. I will post my specs below. Any help or comments on the matter would be greatly appreciated. If you need additional Information please contact me. Thanks in advance.

RE: Replacing RAM in Alienware Aurora R4

Hi,

The Alienware Aurora R4 desktop system supports memory type Quad Channel DDR3 1600 MHz and Quad Channel DDR3 2133 MHz XMP. It does not support memory type DDR3 2400 Mhz, so that must be why its not recognizing the ram properly.

RE: Replacing RAM in Alienware Aurora R4

I've been having the same problem. I tried 4 8gigs of viper 1600Mhz and the same thing happened, the computer cycled on and off a few times then just stayed on but both monitors were black. I've returned the ram that I purchased and purchased some from Dell. I hope that works.


Did you find a solution to the problem?

RE: Replacing RAM in Alienware Aurora R4

My solution was returning the Corsair Memory and I bought this:

Memory: G.Skill Ripjaws Z Series 32GB (4 x 8GB) DDR3-1600 Memory ($139.99 @ Newegg)
Total: $139.99

This arrived a couple weeks ago plugged all four sticks in and my computer booted the first time without problems. It was actually just plug and play which was very nice given my struggles with the corsair memory. It recognized all 32GB at 1600Mhz and loaded the XMP Profile.

My problem was that I missed the fact that my processor the Intel I7 3820 is limited to DDR3 1600 MHZ RAM. Personally I am a big fan of dell computers and I wasn't ready to build my own yet so the Alienware R4 was perfect. I added a second GTX 680 and now the RAM and I have been able to overclock to 4.2 stably tested with Prime 95. 

I looked at dell's RAM and I felt it wouldn't quite give me what i needed. Since I use Flight Sim I needed relatively flexible RAM. The G-Skill RAM above that I bought comes stock at 1600 Mhz but has a little headroom. Often times its running at 1666Mhz and I haven't had any problems.

Next time around i will definitely be building my own. Here's my part list for my next build.
