When this happens, LabVIEW is using, according to Windows Task Manager, only 750MB of memory, maybe 950MB max, and I've run things successfully when LV was using 1.6GB of memory. I've increased my virtual memory settings to 3GB for Windows Vista 32-bit. I have 4GB of total memory, and I have a duo core 1.8Mhz CPU. Attached is my VI. I read in a waveform of singles, do a conversion to doubles, and try to write it to the board. I use DAQmx Timing Sample Clock instead of "Use Waveform" because using the sample clock results in one less copy of the data. I read the data in as singles because that's how I'm writing it out beforehand, and it's much faster to read in singles than it is doubles. Is this something that will have to be split up into multiple writes? If so, how does that affect performance? I have a very limited timeframe (<1s) to write this data out. Thanks for any help, and please let me know if I need to provide more details. Solved! Go to Solution.

I have configured my DMA FIFO host side buffer, but it is failing to allocate enough memory. I am receiving one of two errors: Error -52000 occurred at an unidentified location
Possible reason(s):
The specified number of bytes could not be allocated.


Error -50352 occurred at an unidentified location
Possible reason(s):
NI Platform Services: The requested memory could not be allocated.

How do I resolve this error? Solution: This is an issue with the way that NI-RIO allocates memory on 64-bit operating systems. In NI-RIO 3.5.0 and later, the driver will attempt to allocate the memory in the required address range. If this fails, the driver will attempt to allocate typical, fragmented, non-paged memory. This should work for 64-bit systems with 3.5 GB of RAM or less. For systems with gr
