So I have recently built a computer after being out of the loop for 8 years. I have now encountered a problem which needs clarification. My new board is the ASUS Maximus V Formula w/ 32gb of Patriot Viper 3 Black Mamba edition ram.. This ram comes in 4 sticks of 8gb. So the issue I am having is that I can actually boot up with any combination of 3 sticks but installing a certain certain stick into the forth slot or in any combination with the other 3 gives me a 55 error code which is suppsed to be no memory loaded... I would suspect this to be faulty ram but when I remove all the other ram and insert this certain stick alone then I can get the computer to boot up. I am no hardware tech and only know a few tricks but this has me baffled... I am currently running 24gb of ram and through the bios I see the ram is running between 1.5-1.6v and is running at around 1600mhz even though its supposed to be 1866mhz. Any thoughts? Thanks in advance.

  1. Hi, What memory model? Do all four slots work (by testing them with one RAM stick)?

    Yes each slot works and I will give you all the info on the sticker of one piece of ram. It is as follows

    32GB 1866MHZ (10-11-10-30) DDR3
    1.5V UDIMM (4x8GB) Kit

    This seems to be the only relevant data.
  3. They are listed as compatible by Patriot ( ), but it seems they don't run as expected.
    What you can try: lower the frequency in BIOS at 1333 (check the SPD with CPU-Z) and test or return them and get a different kit ... maybe different brand?
  4. Yes I have just been talking to the people who sold me the ram and they believe that the ram is defective too so they will special order in a new set and I will see if it does not work any better. Thanks for all your efforts.
