Altera DMA Issue

Hi, 

 

I am using the Altera's free application interface /DMA that comes with PCI Express core. I want to know whether this DMA has completion reordering feature or not? I used my hardware setup with jungo windriver. I am transferring 8Gb data from PC to DDR3 memory using DMA. On one PC I found that the received data has some ordering issue quite frequently. But the strange part is that I am not getting this problem on another PC even after several transfers. 

 

Since 8Gb data is quite big I should have problem on the other PC as well. What else can be the issue? 

 

 

Thanks
