title: Would it be possible to figure out the row buffer policy of DRAM on computer (open row or closed row)?
body: <p>Open Page Policy:
  When there is locality, row buffer is kept open meaning row buffer hits are cheap and misses are expensive (the precharge time is on the critical path).</p>
  <p>Closed Page Policy:
  If there is little locality, bit lines are precharged immediately after access so nearly every access is a row buffer miss.</p>
  <p>Since row buffer hits are around 20ns and row buffer conflicts are 60ns, would it be possible to simulate this using rdtsc as I transfer bits and measure the time? I'm assuming it is not this simple..</p>
