Oldschool DDR2 - SPI32M @ 670 MHz+

[CryptiK]

I found myself in a rare mood of hardware nostalgia, so I thought I'd bust out my old DK X48-T2RSB Plus and some Team Group PC6400 C3's.

Here's the results.

Timings: 5-5-5-15 | tRFC 42 | tRRD 3

Test run - 670 MHz | PL8 | 2.45 vdimm




675 MHz | PL7 | 2.496 vdimm




680 MHZ | PL7 | 2.544 vdimm




I wanted to get >680 MHz SPI32M stable since not many people have managed to do so. I was hopeful this kit could do it, and it didn't disappoint. The board did well too. I'm going to stop here, raising the voltage anymore would be reckless and things weren't scaling well anymore so gains would have been minimal.
