Ram is in slots 1 & 3 as per the instruction manual. In the M.I.T screen, it can see both 2 GB sticks, but only 1 is listed as enabled.
Will try reversing shortly and see if it helps - has this been known to make a difference before?
CPUZ shows 4GB installed, 9-9-9-24, 2T command rate, 88 tRFC, FSB:DRAM 2:12, and DRAM frequency of 799.5 MHz (which at double rate makes 1600, so that seems ok).
Let me try that reversing and see how it goes...
