I don't remember what type of installation I did

is there any way tto check if it is SS , classic etc?

i have page size 16384

page buffers 0

i cant see any info about cache

as you say then i had a problem somewhere becouse u used FB32 with 20gb ..

i dont have a full application just i made a test to save simple blob for check the size

the strang thing is the to aovid the out of memory error disappeared when i installed on the same machine FB64 and could save more images just speciginh in FIREDAC the "vendorlib" option dll
