Micron ICs are very weird. I have twelve 8GB modules in hands right now, 4pcs week 1424 (USA) and 8pcs week 1428 (Puerto Rico).

On MSI boards (X99 SLI / Mpower / Xpower) all w1424 sticks run 1500...

Just getting familiar with the set and ICs before starting with the review. Only adjusted primaries and voltage so far. Secondaries are manual loose, tertiaries Auto.

DDR4-2400 (cpu 4000, cache...

tight subtiming tests at 1.46V with X99 SLI Plus and X99 Xpower

37-38 is the lowest I could get the MSI board to train, anything lower set in directly or via RTL compensations would not POST.

When my board was shiny and new, getting PSC to run 1333 8-12-8 on...

There aren't many Kingston reviews out there, but looks like Hynix MFR to me.

1429 6-10-6 is the new standard now :D

just for lolz

TaPaKaH - 5:55.625 - 100x50 - 1400MHz @ 6-10-6-22 - MSI Z97 Xpower - GSkill PSC - 2.26V - LN2/LN2

Yes, it went from 225 to 400 euros in Germany and from $330 to $500 in the US.
G.Skill must have sent too many samples ("everyone" has got one or two) so now they need retail customers to compensate...

TaPaKaH - 5:54.562 - 102.1x49 - 1429MHz - 6-10-6-22 - M6I 0038 - GSkill PSC - 2.20V - LN2/LN2

Is that 4GB or 8GB sticks? I could never tun tRAS and tRFC so tight on mine at 1333.

new Hynix DDR3 ICs are out: 4Gbit BFR

some results

800MHz / 7-9-9-24 / 1.50V
900MHz / 7-9-10-24 / 1.76V
900MHz / 8-10-10-24 / 1.49V
1000MHz /...

yes, all on air, normal ambients.

Might be a mistread. When I set 4 on ASUS and use ASRock software, it reads 3.

tried two sets of 2400C9 recently

set #1 (141625.........) on ASUS Z97:

Unless you run tWCL 8 or lower, CL8 is CL12 "for real" :)

Could there a superloose subtiming or special option for raw freqs in the BIOS, which renders the CL value you set in by hand irrelevant?

what were the subtiming values for your runs?

I think a new thread for DDR4 could be in order :)

100:2666 was fixed on MSI back in July, but I still prefer to pretest with 125:2666 as same profiles can be directly used afterwards on LN2.
I couldn't get AIDA to run on XP (it just blanks when I...

some SuperPi 32M test runs with four Crucial 2133C16 OEM modules:

Yes, these modules are based on Hynix MFR (DDR4 version).

PSC 1400 air on M7G:

Had to use G3258 for these runs. Same settings with 4770K will need about...

Lots of options. Most likely are Micron D9QBJ or Samsung 4Gbit B-rev, but they can also be Hynix/Samsung 2Gbit or (extremely unlikely) Hynix 4Gbit MFR.

EDIT: added Micron D9QBJ information to OP.

testing M7G with PSC, G3258:

I'm not entirely sure CL5 and CL6 are real.
Even super good MFR barely have enough potential to suicide at 1000-1050 CL6 on air (with 2V+).
I wouldn't expect them to scale on LN2 so well that they...
