DRAM Idle Timer

DRAM Idle Timer, what does this function do?
Settings: 0T, 16T, 32T, 64T
Is there anything to gain with bandwidth or latency using this setting? Maybe increased stability?

256 gives more stability but lower performance

0 best performance but less stability

you have to see what likes you cpu

256?

Use 0 for the best performance.

I see an "Infinite" setting there as well, is this setting any better?

Nope, 0 is better.

Really! 0 is better, hmm, what does the Infinite setting actually mean/do, I kind of don't understand it, since it is not a number.

Ok let me explain how it works a little better. This timing sets the number of clock cycles before the memory controller forces open pages to close and precharge. If you set this to 0, then the memory controller will immediately precharge the open pages as soon as there's an idle cycle. Infinite means the memory controller will never precharge the open pages prematurely.

Best way to find out what the best setting for this is to set 0 and run some benches (PI, Sandra, etc) and set infinite and see which runs faster.
