Wow! That's surprising, I expected the 2133C9 PS kit to be a bit better. Have you tested 2133 7-9-7 on the PS kit?Quote:

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 preset, but can't get it Super Pi 32M stable. 1M is easy though.

They also don't mind booting on high volts (1.85v+), so it seems like they can be good on air...I wonder if I just need to tweak something.
Have you tested more CPU input voltage?
My Giga's & Asrock like 1.9+ I find you can be unstable then bump input up a notch gaining stability untill you got too much voltage & then you start to become less stable again.
Anyone have an idea about these G.Skill Tridents? 2000MHz C9's
0640 is unnamed in the first post other than Elpida

BBSE and not good ones, you should be very lucky to find a good match of 2000C9 BBSEs
Figured as much, thank you.
A friend of mine received from RMA a f3-12800cl8d-gbrm kit (2x2GB rated 1600 8-8-8-24 1.60V), because the previous one (BxSE) ended up having a consistent faulty address (at any settings) that hci memtest wouldn't always pick up unlike memtest86 under DOS due to full cover.
Now, this serial starts with 13431200 (2013 Oct on hologram) which seems to be PSC on the list (x200?), but these sticks are single sided, with 8 ICs each.
They seem really bad compared to the previous kit. I don't know what ICs are under the spreaders. My testing was very limited as there were meant for a stock 955C2 under a M4A89GTD PRO (this same C2 could run 2x4GB 1600 7-7-7 D9Qxx without a problem at 1.50V).
1600 8-8-8-24 1T 1.60V - the rated timings are fine
1600 CL7 always fails, can't even POST at 7-7-7, 7-8-7 or 7-8-8 2T with 1.60 or 1.65V.
1333 CL6 6-6-6-24 1.65V fails to boot windows, and craps out in memtest86 immediately.
0640 is unnamed because it can mean different ICs on different kits, but hiwa is right of course, 2000 C9 with 0640 are BBSE.Quote:

@Don_Dan As the rated 1600 8-8-8-24 1.60V does fine, 1333 CL7 seems less interesting, that's why I didn't bother to test other than CL6.
@TaPaKaH I presume you mean the Elpida BFxx I've seen on some KVRs, but there isn't much testing around.
There are also ICs like Elpida BCSE, these are older and did not too bad, I had these on 1600 7-7-7 rated 2x2gb single sided kits and they did around 2000 8-9-7 and up to 2400 10-10-10. But I assume your new psc do not have this quality, and I am not sure which Elpida IC might have been their inspiration
@websmile: They seem inferior to those BCSE by far up to 1600, and unfortunately if they scale well on MHZ with added latency, this isn't the setup to test them.
Just got my hands on a F3-12800CL7D-4GBRM ripjaws blue kit (7-8-7-24 1.60V 10491040..., probably PSC T?). Finally, I guess these will replace my OCZs, they do 1600 6-8-6-24 1T 1.55-1.60V under hci memtest without any tweaking. Stock CL7 (@1T) 1.40-1.45V seems solid, pretty much like Eco on AM3.

Some of the last 1040 GSkill psc, used ICs are XEJ
some XEJ are very nice under cold but no 1400 C6 here :S
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 I've read, hence the code 55. If I manually set tWCL to 8 (which is what the Tridents default to) they'll boot just fine.
Your mems are better than mine, one kit I had failed also on profiles and handsettings, cas and trp lowering needed that much voltage i had to run them 10-11-10 at 2500 on ivy...
P.S. What was indeed funny is that these were not bad mems apart from that, I could run them at 1000 8-8-8 for example and they had quite good trcd limit - might have been good mems for cold, which I do not use
Battled with this exact issue this weekend with my 2133 9-9-9 Tridents. Run without issue and tight subs at 2200 7-9-7 and lowish (1.715~) volts but as soon as tWCL is set to 7, nothing can get them to boot.Quote:

hi
i will receive this kit from rma, can someone let me know what are they and should i keep it ?
F3:12800CL6D:4GBXH
S/N: 140218000070204
140218000070203
thanks for any help
Elpida according to the sn, could be BBSE or a variation of other ics, if they are worth keeping them only tests will show
hi websmile
thanks for your time
i have seen in the first post that 1800 was for elpida, but was hopping someone knew something more about them : -)
thanks for your help
I'm going to purchase a quad kit used memory and they have this serial, it should be HCH9? Does this sticks can do 2600+ or due to high density shouldn't except much?

These should be Samsung 4Gbit B-rev "HCH9". You shouldn't expect more than 1200-1250MHz out of these.
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 worked, and the board trained with high VDIMM no problem this time.

Now if I could only find a way to get some of my PSC to do 2666 8-12-8-28-1T and pass :(
