Out of memory in module quartus_fit.exe

[Altera_Forum]

Hi, 

I am trying to map a 256 byte memory in stratix V. My design synthesizes properly but while fitting it gives an error "Out of memory in module quartus_fit.exe". I am wondering what can be the cause of this. My computer configuration is : OS: Windows XP Professional Total Physical Memory: 4GB Available Physical Memory: 2GB Available Virtual Memory: 2GB  Page File Space: 5GB   I am using a subscription version of Quartus II 11.0. Please note that I have been successful in compiling designs upto Stratix IV. Can anybody figure out the problem here.  Thanks Anandaroop Ghosh

Basically, you do not have enough memory. IIRC, you need a minumum of 3GB phyisical memory (available) to compile stratix 5 properly. If you have a 32 bit system, then you actually only have 3GB Max available to windows becuase of system overheads. There is a boot setting somewhere that increases the 2GB cap per process of physical memory, but I cannot recall where that is. 

 I would recommend moving to a 64-bit machine.

i agree on the recommendation of a 64-bit machine
