I have fixed hundreds of E2's and I never used Diag disk because its bugged, as well the memory disk.
Sound memory test : sample one and only long signal (whatever music or sine) and see on wich segment the problem appears. After the half of the lenght ? The problem is on the piggyback board. If this is it, intervert a quadrant (a quarter of the memory chips of the piggyback) with another quarter.
Problem is the same and at the same place ? Its on another quarter. Exchange a known working queter with an unknown one. If the problem is still the same, you have located the bad quarter. Intervert half of the bad you quarte have located with another half of a working quarter. Etc...
By applying this method, it takes 16 operattions to locate a faulty chip among 65 536 (2**16)

But, what is the problem of your machine ?
