Alienware Aurora-R4 Four beeps

Hello,  i have an Alienware Aurora R4, it recently has been giving me 4 beeps which is the RAM read/write failure. I have try reseatting the memory after i have clean out the channels, this did not work. So i brought new Memory hoping this would change the out come. It work for about three days then when back to the 4 beeps before post. Too which i tried to reseat them again, nonething happen. Have try dell's self link from another person with a different problem on thier alienware, none of this has worked.   please help, thanks

thanks tesla,  I have Tried using the old memory and try one stick at time but it doesn't work. The pc won't get pass post, and the new memory i have is a total of 6gb, where my old is 3. everything the same one speed. i just add 3gb to the memory. This only thing i have change every is bone factory.

Still  no luck on reseating the memory, i tried leaving my pc unplug for a few days since last time i did that it started but that too hasn't work. So does anyone know how could fix this or maybe do something else?

6 slots is R1 (x58 chipset), not R4.

Pretty sure R1 will run (although in single-channel mode) with one good DIMM in slot 1 of first bank. See Service Manual for location.

my machine came with 6 slots and the memory it came with was 1gb in slots 1,3,5. i have tried placing memory in each slot by itself no luck. i think its the mother board. i'll just have save the hard drive to use later, so i dont lose my  stuff on it. it's to bad it's only about a four year machine.

tesla, i believe you are wrong, i have look at similar machines and mine is R4 not R1.

A four year old Aurora with 6 DIMM sockets is an Aurora (aka Aurora R1). It has an Intel x58 chipset and tri-channel memory. Memory is installed in sets of 3.

It's important that you know which you have so you can get proper drivers, Service Manuals, parts, etc.

Sorry to resurrect the posting, but I seem to have run into the same problem. I upgraded from win7 to win8, clean win8 install, and had nothing but bsods. I recently reverted back to win7 clean install again but now i seem to have lost functionality of dimm slot #3. I have disconnected all power ports and held the power button down for 30sec etc... I took all the dimms out reseating memory and processor re- applying thermal compound and still no luck with dimm slot #3. I can have all dimms in minus that slot. I am thinking bad slot but just wanted info from others as to what they thought it could be. I am at a loss. If I have to replace board i will, which might be the likely case, but thought i would just post on this thread. And again sorry for resurrecting this post.

oh and forgot to put what type of system i have. Sorry, first post to a forum 

Alienware Aurora R4- Intel i7-3820 - Liquid Cooling

G.SKILL Sniper Gaming Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 

120 Gb (OS) Kingston SSD Now V300

256 Gb SSD Samsung 830 (game drive)

Windows 8 should have worked, but not if bad motherboard or incompatible RAM.

Try with original stock memory, all matching, all slots filled. Should report correct in BIOS. If so, test with www.memtest86.com boot disk

Also try resetting BIOS to defaults and Dell Diags (outside of Windows). If you can't get above to work without errors first, no use trying in Windows.

My bad I meant dimm slot 4 not 3. I tried the above no avail. Still can't get video with all slots filled even with stock dimms.

See PDF manuals and how slots and Banks work. Only use Bank-1, which should include Slots1 and 2 only. Test all DIMMs there. If they pass, all DIMMS are good and you likely have a board problem.

G.Skill 2x4gb = 8gb is an acceptable config for most uses. Might work like that. Leave entire Bank-2 (with bad slot as member) empty. I think it will be Single Channel (but normal DDR3 rate). However, there will be less DIMMs to access, so might work out ok (access-speed wise).
