What sort of mem is this?

[Noxinite]

Samsung. But not D-die.

How far can you push 9-12-12 on those sticks ? What voltage you used ?

[Noxinite]

RCD and RP seem weaker than D-die. But RDRD, RFC and the RDWRs can all go tighter.

Perf seems a bit off too, so maybe I have some timings too tight as well.

This is at 2.35V.

[suzuki]

D-Die means Hyk0 or HCH9 ?

i cannot compare now ,but can you make a run at 5450 with cpuz and coretemp opened (it was requirement for a contest) as my time like this was 5:31s with 9-12-12 at 2840 mhz.

[Noxinite]

I have a 4GHz i7 32M run at 2800C8 that was 7m 19.6s.

[suzuki]

Best run  at 4 ghz ,on the os i am using from a friend :

 

I guess yours are stronger with those timings.

[Noxinite]

See it's not as fast as you would expect. Not sure if it's my OS or timingd set wrong.

Oh, so these are the "weird" Samsung (1Gbit G-die or something similar) that G.Skill were using on their 1600C9 sticks at some point?

I saw some of these do 1400 9-12-12 a few years ago and reckoned they could be a superior choice to 2Gbit D-die due to lower density and hence lower tRFC.

[Noxinite]

The weird thing is that they were made in 2011.

I see F-die sticks made in 2011, so it's not werid. G-die produced until the end of 2012 AFAIK

G-die DIY available =)

[Noxinite]

I bought +10 each of  2GB and 1GB G die sticks. 1GB clock much better, but single side = crap efficiency. Might be interesting for freq valid though; I could do 3600MHz (dual channel) without too much effort.

[ZFeSS]

Is it Samsung original sticks?

[Noxinite]

Yup.

[ground]

Should put them on a high MHz PCB then
