Figuring out G.Skill's SNs

[Reefa_Madness]

I agree with dumo, get them while they're new, now you can be sure about what you're receiving. I wanted to buy a Samsung kit for Christmas, but I think I'll buy it now, who knows if they might change ICs in the meantime.

If they haven't already.

I have a 2x2gb set of Trident F3-17066CL9D-4GBTDS (1.65v) that I thought were PSC but after checking them again the have "0660" series number.

I didn't know that they also "spec'd" this particular kit with BBSE... I thought the Trident 2133C9 kits were mostly PSC?

Serial #: "94806601415xx"

@ PolRoger.... think your keyboard is playing up!!! mine does it all the time lol F3-17066CL9D-4GBTDS

Hello everyone.
Yesterday I recieved 2x4GB G.Skill Sniper Low Voltage Series DDR3-1600 CL9-9-9-24 (1.25v) for my new AMD Mini-ITX build.

Sticker says Oct 2012, Week 1242, Full SN: 12421800xxxxxx. I saw on AwardFabrik 11200850xxxxxx.
Hopefully they clock well, I have high hopes for at least 1866 9-9-9 1.5v.

Curious, and surprised after reading that there were Elpida ICs inside, I opened them up... IC reads "U235V8C08A07".
PCB is a 6-layer BrainPower PCB rated for DDR3-1600, B63URCB 0.70. If this stuff is Elpida, I suspect it is EFBG.
I didn't take any measurements, but with my photos I should be able to figure it out after measuring PCB height:

Yes, those are Elpida ICs. Are your sticks single sided or double sided?

If they haven't already.

So far all the new kits I've seen are clocking well!
By the way, check your PMs.

You mean 2x2GB set, right? Your part number is also a bit mixed up, it should be F3-17066CL9D-4GBTDS.

This kit is definitely using BBSE ( maybe a very small chance for MxH-E Hyper ), they were never using PSC for this kit as far as I know. Binning PSC for tRCD 9 at 1066MHz is too hard when BBSE can do it easily. Only on DDR3-2000 ( and maybe lower ) Trident/Ripjaws kits there are different version with BBSE or PSC chips.

Thanks Dan for the clarification...

Yes it is a 2x2gb kit. I'm not really sure where/how I came to think that these kits were PSC? I guess I'll need to do some more testing with it using IB.

[BeepBeep2]

Double sided.

[Don_Dan]

Double sided.

In that case they can't be EFBG. 4GB double sided sticks means 2Gb IC. They could be DEBG or EEBG, but that's just speculation.

@stunned_guy:
The pics I promised you ( sorry for the not-so-great quality ):





1GB Elpida OEM stick.

[BeepBeep2]

Okay, makes sense.
They do DDR3-1600 8-8-8 at 1.5-1.525v in a very warm environment, I haven't been able to thoroughly check stability outside Memtest86+ and general use. DDR3-1600 8-8-7 takes a little more voltage. Maybe 7-7-7 could be done with 1.65v, but I haven't tested yet.

I think they are rather decent. My ASROCK Mini-ITX motherboard won't do DDR3-1866(+) with them though even with CL11.

They can do 800MHz 8-8-8 but 933MHz 11-11-11 isn't working? Weird. But then again, I haven't seen any info about how the latest Elpida 2Gb ICs clock yet. Will you test them on another board?

Thanks for pic

You're welcome!

I can, but the only other boards/CPUs I have available right now are Phenom II.

[Don_Dan]

Thuban or Deneb? If it's the latter it might limit you too much... Please test if you can do 800MHz 7-8-7 on Trinity.

[BeepBeep2]

Deneb, so about 1800-1866 MHz will be it.
I can't do 800 MHz 7-8-7 on Trinity, tried up to 1.7v. I think tRP is the limiting factor because 8-8-7 needs almost 0.05v more than 8-8-8. It seems like this board just sucks.

EDIT:
Seems tRFC needs to be set to 160 at 1600, XMP profile shows 130 but not on AMD , 110 fails Memtest86+ pretty quick.

Hi,

Id like to know memory IC on my TridentX 2400 C10D 8gtx.

it is single sided, S/N 1236150xxx

Is there a page to check out Gskill mem IC?

Samsung, they should work fine in your board.

Did you, by chance, look at the first page of this thread?

[Tomasis]

thanks Beep and Reefa, I see the thread is new

Interesting that my 1 years old Ripjaw 1600 cl9 has Hynix chip and dont OC at all.

You forgot a "0", but your kit is Samsung ICs ( K4B4G0846B-xxx ). On some AM3 boards they refuse to boot up ( only 990FX from what I've seen ).

yes, what im experiencing just now (gigabyte ud3 1.0 990Fx)

Gigabyte support told me that same modules as mine , booted up on the same mobo there. Ways to figure out is to check my mem at a shop and to get know S/N that worked for Gigabyte technician in order to clear out the mystery

Ask them if their sticks are double sided and which revision they have in the labs, the first batches of the 2400C10s were double-sided, most likely Hynix CFR.

lolz ... bc of this info ive determined that some trident bbse i bought from splave is actually psc. refund time
thats odd though, wouldnt expect 9-9-9 2000 to be psc

serial: 10131040198276

As far as my sets went the 1040 9.9.9 2000's that were 1.6v were PSC & 0640 1.65v ones were BBSE.

There are two versions of the Trident/Ripjaws 2000 CL9 bin, just like C-N said:

PSC binned for 1000MHz tRCD 9 at 1.6V is actually pretty nice...

Edit: I checked it again and there seem to be three different version:
0640 1.65V Elpida BBSE
0640 1.6V Elpida BBSE
1040 1.6V PSC

Look at here: http://www.hardwareluxx.de/community...-924433.html#d

I had that same sticks single sided with 1219AB40xxxxxxx and nice to see that with other numbers from G.Skill they are still single sided.

Imo, Trident 2000C9 psc with batches 10041040xxx ~ 10231040xxx are the ones to find

Some of these kits need 1.88V+ to blast through 32m on air @ 2600 8-12-7-28 twcl7 with ultra tight secs/terts
