    eva - how did you determine those secondary and tertiary timings please ?

    going to give them a go as you are at much lower volts than me I'm using manual for primary timings and for tWCL - but all rest are on auto/spd on my Gene V

    thanks

    And which number do you look for? Read, write, copy, and latency are effected differently with speed and timings. Slower speed and tighter timings will increase some but decrease others, and vice versa.

    I don't think the memory or Z68 Maximus IV Gene-Z board or my 3570K IMC is allowing me to do 2256Mhz 9-9-9-x. Just updated Maximus IV Gene-Z from 3305 to 3402 bios, so re-testing again. Probably, need to really test this on Z77 board to be sure.

    I bought 5 pairs of Samsung Greens all 1149 batch. There is a variance in behaviour between each pair. I have 2 pairs which at low volts 1.4v onwards scale nicely at 10-10-10-24 1T all the way to 2310-2314mhz then need 11-11-11-x all the way to around 2380-2389mhz. Then I have 2 pairs that clearly at lower 1.4v volts need 10-11-10 or 11-11-11 from 2200mhz and scale to around 2349-2365mhz.

    I have yet to really touch secondary and tertiary timings yet (besides tRFC below), just getting a feel for primary timings and frequency headroom each pair of Samsung Greens has based on voltage/vrm adjustments alone first.

    I look at the changes that I get in this only when tuning for a single speed. That said, once you change speed you can then start over and, once tuned, compare results with the previous set.

    My primary result to look for is the copy number but I cannot remember what it is that I read to make me take that decision.

    Got mine the other day. Haven't been able to use them yet though.

    New board doesn't have a PCI lane and PCI doesn't work with PCIe (didn't know that) so now I have to buy a new wireless adapter

    Man these things are short though.

    Thought I'd throw my hat in the ring with these HYK0 sticks. I've been testing on my RIVE+3930k setup. Unfortunately I couldn't do 1200MHz 9-11-11 like OnePageBook could, but I managed 11-11-11-28 1T with untweaked subtimings at 1.56v for HyperPi 32M stability.

    I need 1.7 V for @1200 9-11-11-28 on RIVE.

    Play with Vccio, Vccsa, transmitter slew and receiver slew. 2400 9-11-11-28 should be possible with 1.65V. I will sure try when my sticks come in from RamExpert.

    I wouldn't bet on it. Though one of my pairs does 10-11-11-22 2400 with 1.6v, the other pair needs 1.65v for this.

    Which board do you have and what week are your sticks produced?

    Opb used a Maximus V Gene which is notorious for it's ram clocking abilities.

    Week 5 seem to be the favoured production week for these sticks altough i've been told all sticks from 2012 should be fine.

    Edit: I see OPB used a Rampage IV Extreme so on the MVG it should be even easier!

    I tried 1.65v. Didn't go over that as these sticks don't seem to like high volts.

    nope they dont remember that are 1,25 so long way to 1,65

    the samsungs scale well on volts but they're already scaling mine where batch 1147 and they did 2400 11-11-11-28 1T on Z77, but no CL9 at any volts

    cheers !

    I have one pair of 1205 and another of 1147, the 1147s would at least boot at CL9. Combined they can do 11-11-11-28 on X79.

    My 1205's run nice up to 2200 either slack ON low volts or tight (CL8) & high volts on my UD5H then depending on timings/volts you can get them prime stable up to 2300 fairly easy. 2300 ~ 2380 they run but I have trouble booting sometimes they fine other times no go. 2380 + single stick runs & boots fine here's a suicide shot just to see what one stick could run..... shame I can't get 2 sticks like this.
