@mockingbird
Those must be 2 or 4Gbit ICs. As I don't know about BBBG much, I didn't add them to the first post.
But I believe those won't be anything spectacular, otherwise makers would be using them on the non-trivial models.

[Don_Dan]

They looked exactly like BBSE chips,E91xxxxxx,but i am pretty sure they are not BBSE,meaning 2200 can't boot without 9-10-9 and still not stable regarding voltage,can't even do 8-9-8 at 2000....

some BBSE can be this bad

So far I've seen three kits with their HS removed, and all of them were Elpida BBSE OEM/eTT. I agree with Sam, I think they're pretty bad BBSE. A picture would have been very nice though!

Anyone know anything about Elpida "BBBG" found on Kingston ValueRam?

They're 4Gb ICs ( J4208BBBG ), but right now I can't even find them on Elpida's site. I'd prefer the sticks with D9PFJ chips.


Alright, since it has been brought up by Alex-Ro, Splave and XBrytanX, I'll share my private list of Elpida OEM chips and some speculations. Feel free to correct me and please don't blame me if I'm wrong!

For almost a year I've collected all the info I could find about those chips and put them in a list:

Please note that ihog6hog has posted some thoughts on this at i4memory.

[TaPaKaH]

This makes perfect sense, 7th symbol + lack/presence of stripes + density is what you need to decipher these Elpidas.
Will put this info in first post, kudos to ihog6hog.

Does anyone know what IC's OCZ Platinum 1600 CL7 (OCZ3P1600LV6GK) have? 30e OK price from those?

Just buyd G.Skill Pi 2200 CL7 for 60e, not bad deal?

Does anyone know what IC's OCZ Platinum 1600 CL7 (OCZ3P1600LV6GK)

My set are Micron D9JNM

[Asmola]

My set are Micron D9JNM

Then i can forget those. Thanks.

[TaPaKaH]

I had a set with Elpida BBSE, but it was pretty bad (1100 7-9-7 needed 1.80V)

[Asmola]

What IC's on these? Looks like Hyper's or D9GTR's, but could it be BBSE's?

http://uk.hardware.info/productinfo/...specifications

Edit: Looks like those are specified to 2.1v so must be old micron ic's..

[bullant]

Awesome thread Sam

[gungstar]

time to confuse some of you guys. )

7th symbol is B, but it definately not BBSE, no stripes and shape of IC differs from BBSE but looks very similar to PSC and BDBG
but oc is BBSE like

[Splave]

can you get a picture of the side, and copper tab placement?

Some of your posts contributed to my little theory, and now you come here and destroy it. Not cool, man, not cool.

What do you think it is?

Yeah, I added it based on his photo some time ago, I guess he already posted it in the Team Russia IC thread.

[websmile]

On 2133 c9 trident I have also ics marked as Elpida, without stripes, looking like PSC from the side - they do 1100 7-9-7-21 easily at 1,65v, might be some OEM-Elpida out of the joint venture with PowerchipSemiconductor, there were lots of charges PSC gave to Elpida for paying debts. I think I can leave the Heatspreaders on then

[sin0822]

You know this makes me want to re test my 2133 c9 Tridents because they seemed to stop at 2450 8-10-7-22 almost instantly, wonder if they are this hybrid PSC/BBSE dimm you speak of and if raising tRCD to 11 might help them clock higher.

[websmile]

Mine have trcd 10 limit above 1250 air, but need much voltage to lower cas and trp - but if yours have lower trcd-limit, raising to 11 might improve the previous result

2GB Geil ULTRA PC3-17000 CL=9-9-9-28 1,65v GU34GB2133C9DC

all over net write they are BBSE ICs, but i dont think that info is relevant for all geil ultra 2133cl9
i have here 2 kit geil ultra 2133cl9 , same behavior... all can pass 32m 2400 9-10-7-24 twcl7 , if set cl8 refuse boot
if set twcl6 ..boot ,but fail 32m
2600 cant boot even with loose latency/hight vdimm

[Alex-Ro]

I had 2 kits also,if yours can get 2400,mine were not capable of doing 32M doing DDR3-2200 9-10-9 stable at any voltage.This is one interesting fact,because i can't get how geil can guarantee DDR3-2133 9-9-9 stock,but my kits would fail DDR3-2200 no matter what :?

[crustytheclown]

Same here... easy 2133 9-9-9@1.65v but no go 2400 no matter what timmings-voltage combination... went straight to 24/7 machine...

[websmile]

They need ridiculous high voltage for 1200 if they do this, all evo one and Ultra 2133c9 Kits I had years ago before realizing they are cr.. did 2200 9-9-9 around 1,65v and below, but failed 2133 cas7-9-7 at 1,65, and all had bbse, there are few ICs that can do 1066 trcd9 and Geil used no Hypers...

[nachtfalke]

if Geil ultra and evo use BBSE ICs , definitely are the worst bbse and the cheap batch from elpida

[Olivon]
