Does the IALGO=38 work for large supercell?

I run molecular dynamics simulations of hundreds of atoms, when I set ALGO = Normal or IALGO = 38, the program always runs as RMM: instead of DAV:. But when I run the test (H2O md), the program runs as DAV:. Is it true that DAV does not work for large supercells or I set something wrong?

DAV works for MD in large supercells as well, please check your OUTCAR file for the actually used choice of ALGO.

I checked OUTCAR, IALGO=48. In case that I removed all the options of ALGO and IALGO, it was still IALGO=48. When I put IALGO=38, the OUTCAR is still written out as IALGO=38. But I agree with you. It must be due to some error I made myself in writing the INCAR. Thanks greatly for answering the question.
