I'm trying to run the Identity function on two large data sets but it fails every time. I don't think it is a lack of hardware as I can run other processes on the same data sets.
I've already updated software, and added the 64 bit geoprocessing add-in, checked and repaired geometry, and done the fix in KB29559 (set ARCTMPDIR env variable to a writable local folder).

Based on comments so far I tried copying data to new file geodatabase, and running the tool from ArcCatalog still get exactly the same error.
I have ordered 16GB of the fastest RAM my computer can take (I current have 4GB). I also have a 6 Core AMD Phenom II X6 1090T, SSD, and AMD Radeon HD 6970 Graphics Card. So I'm not sure what more hardware I can add.
I've also tried increasing the size of the page file which was a suggestion I found on Google with no effect.
