Yes, LN2... hope some day feel the experience of it, it's hot in here (south of Portugal), room temp around 28ºC and no AC, ( a lot of fans bloowing the hardware)
All the best for the competition and exams, specially for the exams.
From my tests, had some improvement. (DDR)
Check the DDR submissions I matched DDR speed (258) from 2nd place, only (tRC) is different.
EDIT
Multi @9, I'd change HT ref, to equal DDR speed @258.
