Nice score man !
Are these Elpida Hyper starting in 6 6 5 18 1t trfc=52 ?

I have been through ddr2 d9gmh and ddr3 psc or samsung, but have no clue for elpida hyper how much i can tighten timings, secondaries tertiaries in particular...

Cheers

Not sure what you mean with “starting”.

The consacrated timing formula is 6-7-5 or 7-7-6 and sky is the limit. There is also 7-8-7 on which some may work better. Up to 1750 mhz i used even 5-6-5 :). Hyper is awesome !

Ever tried going with 5-6-4 or similar? Also considered trying to find some interesting BBSE? I have some sticks that can do 5-8-5 at 2000 MHz at ambient given the right CPU+board combination (excuse the garbage efficiency, wasn‘t running an optimised OS for that, just testing if the sticks could handle 32m at those timings without crashes, sadly didn‘t get around tuning subtimings before the CPU died in a board accident)

I would be very cautious with timings like cas5/Cas4 etc on certain platforms, on sandy bridge for example I tested this long years ago only to find that this was not real.. and it was confirmed several times by others as well - also wcl settings for example on different platforms can influence if timings are real or not, not all BIOS shows and you see at cpuz is real

I have one of the best kits of bbse arround ,i think . It can do easy 2700 8-11-7 spi32m all tight . Never tryed them instead of hyper cause i know untill sandy hyper was the deal and no other kit of different ic’s could beat it . Might give it a try after i relocate as now there is no time to do anything.

 

I remember a post from @nachtfalke on a different forum where he modded a cheap Asrock and it was a beast with timings up to 1800 mhz ,need to find the results. Maybe it is also board related ,who knows....

Sticks run 5-8-5 at 1.84V, not any less, runs 6-8-6 easy at 1.64V. Also some score difference between the two.

Look at samsung power,they were done by nachtfalke. You have also my screen with 5-6-5 ,full timings.
