Have we figured out the SNs for DDR4? Looks like xxxx3400 is Hynix, but there also is xxxx3300 like with this kit.

Both actually. The JEDEC speed bin isn't really important, as long as it's Samsung 2Gbit D-die.
Probably Samsung 2Gbit D-die, 1600MHz JEDEC bin.
Over at OCN, in the big memory thread, SamOCX says it's MFR now: http://www.overclock.net/t/1268061/ocn-ram-addict-club-gallery/3780#post_22662151
Finally managed a freaking 2400 Cas8 run with tWCL6 on some PSC (G.Skill Pi 2000C6).

Starting slow to see what they can do. Basic 2133 8-9-7-24-1T testing right now. Looks like they need 1.70v.

Mystery Elpida IC + G.Skill, Round Two.
I took a chance on a 2014 kit of F3-12800CL6D-4GBPI on eBay, listed as new in the box. I could see the serial from the photos, 14151800, indicating Elpida...
Crappy Hynix BFR (Ripjaws X 2133 9-11-9), won't do tRCD=11 at 2400 :mad:

I finally managed 1300MHz 8-11-7-28-1T out of some of my BBSE, the Perfect Storm 2133C9 to be exact. I used some of the IOD/IOA/SA volts from the Z87 OC Formula thread and found settings that...
I think BBSE need cold and crazy volts for tWCL 6~7 with CL7.
I figured out the issue with the Perfect Storm sticks. With auto subs, if you set 7-9-7 at 2200, the Asus boards try to set tWCL to 7, which is actually ideal but too tight for most BBSE from what...
These Perfect Storm sticks are confusing as heck. They failed Sam's binning method on Ivy Bridge, but they pass the M6E BBSE 2200 preset pretty easily, and I can boot with the tight 2400 1.85v...
2200 7-9-7 gave code 55 on Ivy Bridge, and I don't think Haswell can run those timings at that speed.
The lower-binned BDBG 1600C7 Pi kit can match or surpass them:

I don't know why this was so hard to do on Hasfail.

The DDR IC guide was so right, BBSE doesn't like going much over 1.80v. I miss the old days when more juice...
Guilty as charged :p: Sadly though, they can't compare to the 2133C8 kits from my initial testing. BBSE is a strange IC.

F3-12800CL6T-6GBPI X-Series PSC on Asrock Z87 OC Formula, PSC tight 2400 1.85v profile.

The IMC would be able to do tRCD 11 on some ICs but not others? That's very strange.
Yeah, I get code 55 trying to boot 2400 8-11-8 up to 1.85v and the board doesn't seem to like to train if you go above that on voltage.

Got some Ripjaws 2000 C9 in today. Serial has 0640, BBSE as expected.

Still can't do anything like 2600 8-12-8 or 9-12-9 :(
Yeah, I actually have 6 sticks of the 1600C6 Pi and now three Trident 2000C9. Testing them all one by one, all will boot 2400 7-11-7 but need 1.95V and only two of the Tridents were stable enough to...
This is the first kit to pass the PSC 2400 1.85V preset from the OC Formula! Oddly enough, 1.8v+ wasn't stable enough to pass Super Pi 32M, I actually needed to *lower* the voltage.

G.Skill F3-12800CL7T-6GBPI with 0640 in the serial. Was hoping for BBSE, but these are clearly BDBG.
