Quadra drivers problem with DMA ?

I run a heavy load on file access on PC Windows 10 at the same time I run the Quadra HW. In some situations I get data read from files that contains 3d coordinate floats or other data on Quadra HW on various machines but not on GForce HW on various machines.

I know it sounds really crazy but has anybody seen this. That Quadra systems affects file dma ?

I can add info that all quadra drivers and all HW I have tested has this bug. It could be dma or memory access problems. The bug is hard to detect. It isnt visible when the program is run under a debugger or attached to a debugger. Application verifier doesnt detect it. It is only visible when the sw is run in release stand alone
