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.Quote:

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.Quote:

edit: wow, Maximus IV Gene-Z 3402 bios really changed things for the worse, having difficulty even booting at 1866mhz regardless of timings http://rog.asus.com/forum/showthread...untry=&status= !
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.Quote:

guys does going over 1,65vdimm for daily use my hurt IMC on IVY ? i have team X 2400 CL9 and Patriots can run perfect 2400 to 2500 tight but i want 2600 and they do pass hyperpi but fail memtest i need to pump VTT and VCCSA and VDIMM over 1,68 can use it for daily or will harm IMC ???
thanks in advance
Sergio
my memtweak all versions dont work either :( it used to work i tested both versions, the older one would work but this new noQuote:

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.Quote:

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! :D
I've a asrock Z77 professional, not the best board but it get's by. My stick must be most def 2012 sticks, but if you tell me where can I see the week I'll be able to tell you exactly.

In the red square. ;)
Thanks, worst pair is 1214 as well as the best pair :)
My two 1205 sticks won't even boot at 9-11-11-28.
What voltage did you try?
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 1,65Quote:

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.Quote:

Are you sure ? I can do as far as 9-10-10 @ 2200 below 1.65vQuote:

yes but im talking 2400 not 2200Quote:
