what is considered tight timings on these bad boys?

Let me check the tightest screenshots on air I got. 

Wanna try them on cold and see if they can get tighter.

Will they blend for 32m is the real question :)

[Leeghoofd]

Maybe not for 32M, but X265 might be a winner with these ICs

[unityofsaints]

Hellas!

[FireKillerGR]

These are some results from last week's tests (no fan on mems + aio on cpu).

OGS changing the OC landscape !

Looking forward to cold benchable settings  Memory on fullpot hasn't been around for a couple years!

Is it really fullpot? ?

Yes - no cb/cbb and they scale with voltage big time! No need to heat them up to pass post/get into windows either.

I was going off that message, sounds like they work well, looking forward to see more of these

[zeropluszero]

Monsterous. About time we had another IC.

[Bruno]

Awesome ICs and briliant work! ;)

[unityofsaints]

6G soon

[Noxinite]

Insanity!

very nice mate, , , ballistix ram, .... when you get a good set in any platform are hard to top...superb !!! ?

Nice one!, I was wondering how 8GB modules OC as I got the 4x16GB kit on the same Micron IC and it can easily pass 4000 17-17-17 at stock air and 1.35V. For sure strong IMC. My best chip hits a wall at ~5300.

Do you know which specific IC code is on these chips?  Looks from the micron FBGA and Component Marking Decoder like 8Gbit Micron Revision E DDR4 has a couple of different ones,  not counting other widths than x8;

• D9VPP, a 2666c19 JEDEC bin
• D9WFL, a 3200C22 JEDEC bin
• D9WFP, a 3200C22 JEDEC bin also certified for 'industrial' use down to -40C
• D9XS*, a 3200C22 JEDEC bin with various automotive temperature bins (-40C to 105C)

I'm guessing D9WFL?  It'd be good to have something to call them other than "E-die", I've already seen some folks get confused and think it's the return of 4Gbit Samsung.

Since I checked but don't remember; I will check again once home.

Thanks, I'd forgotten that there are special bins and part #s for crucial.  Not sure those even have a direct equivalent in the D9xxx series, D9WFL's equivalent is C9BJC.

[ObscureParadox]

D9WFN or M perhaps?

Those are 512Mx16 layout (4 chips per rank), AFAIK they're not used in high-performance modules because of less bank groups hurting performance or something.  I've made a thread in memory heaven as I think there's a lot of information to go through.

[flanker]

I never thought, I will be finding Microns on DDR4 :)...Awesome result!

That is one tall, empty, ugly-ass PCB! ? But at least it doesn't have RGB
