Memory error crash

Hello guys,

  First off I am new to modding, the Ark Dev Kit and to UE4. I have 4.15.2 Version installed and I keep getting a memory error crash while working in the editor. Sometimes it happens within 5 mins and other times I can have up to an hours worth of work when it crashes and I am unable to save any of my work. My system specs are as follows: Win 7 64 service pk 1, Asus p8z77-v deluxe MOBO, I5 Ivy bridge 3570K oc'd to 4.3 gig,  16 gigs of corsair vengeance dual channel ram DDR3 1600 pc 12800, Asus ROG Strix 1080ti oc edition and I have UE4 installed on a 3TB seagate HDD. I looked through the forums and I was not able to find any information about this crash or potential fixes. Any help would be greatly appreciated!!!
