Just to re-iterate what Henk said, this tweak is rather safe and if it
happens to cause problems, from what I've read/hear that will become
obvious quite quickly. Hence, it is worth trying - especially if you
have a CPU-GPU imbalance with your hardware and simulation system.
I have personally used this tweak successfully with X79 and Z77
motherboards and various GeForce cards.
