The sense amplifier in PSC and the newer Elpida variants is not as aggressive as what was used in the now de-funkt Hyper. For sub-timings to start with check this image (tighten only when you pass your stability test).

Be sure to enable extreme 0V in BIOS and turn off OCP to DRAM and perhaps VTT.

A few questions:
1. Why do you mention "sense amplifier" here?
(I know of "sense amplifier" in DRAM, but no more than that)

2. Why should "extreme 0V" be enabled?

3. How to "turn off OCP to DRAM and perhaps VTT"

Thanks.
