Figuring out G.Skill's SNs

[michaelrw]

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

Which applies to my kit.. That's good to know. I've been trying to clock these sticks like BBSE since I got them... even though technique and timings should be similar to PSC I've always gotten a bad feeling from these sticks.. Maybe now I will have some better luck using PSC profile as my base instead of BBSE base lol

Don dan and other, for information i got confirmed that the memory modules are doa.

How often it happens that one receives completely dead kit? :-)

It has never happened to me.
I received some kits with one dead module or kits that were physically damaged due to bad packaging, but a brand-new kit has never been dead for me.

Wow thats hard to believe Sad to hear. Send it back or start an RMA.

[stunned_guy]

Found one kit with serial 1240 and i looked under the heat spreader.
I saw that this is not Nanya like somebody thought and its written in the starting post -> its Aeneon or Infineon / Qimonda by the way. Look at the dot in the left, this is the same ic detection like the old DDR2 Aeneon / Infineon / Qimonda style. 2 rings in another, Nanya IC have a very small full dot only.

DDR3


DDR2

[Don_Dan]

Awesome, thanks Phil!

[stunned_guy]

It should be Qimonda not Infineon.
Found the next sticks with original Qimonda IC. Thats very nice, pic will be posted later.

[Don_Dan]

Alright, I changed it!

[stunned_guy]

Look: Qimonda IC with SN 1240



The IC is 1.25 x 0.85 cm on both sticks. Qimonda A1.

Hey hiwa, what PCBs used for top two kits and Flare?

I got 1333 CL7 ECO today, SN is 10250640, hoping for BBSE. ICs are unlabeled though, just some pencil markings white and blue on them and E019A8DA941G...

[Don_Dan]

Nice kits hiwa, makes me jelly!

@Beep: Do the ICs have white stripes on their sides?

[BeepBeep2]

I don't know about "white", but more like grey...at the base probably 1/4th the way up the side:


The copper dot that is visible here isn't visible on all the chips

It doesn't look like this if that's what you were asking:


but I will fire them up and see what they do anyway.

[BeepBeep2]

Looks like -
1600 6-8-6 posts at 1.55v, boots at 1.6v, needs about/almost 1.7v to pass 32m
2133 7-10-7 posts / boots at 1.65v, tried up to 1.75v will not pass 32m
2133 8-10-7 same thing
2133 7-11-7 same thing, gets a little further in 32m maybe...will test more
2133 7-10-8 same thing

BDBE? These sticks are crap.

[Don_Dan]

I meant white stripes like in the second picture you posted, those should be BDBG or BDSE, probably BDSE from your results. Try 2133 9-11-9 at 1.65V - 1.75V.

I can't, OS is corrupt, won't boot

Perfect time to throw a different kit of RAM into my Trinity setup...8-11-8 should work at 2133 though, I'm guessing. I find it odd though that 7-11-7/8-10-7/7-10-8/7-10-7 clock the same...also seems 6-9-6 does not help over 1600 6-8-6.

My RipjawsX 1600 6-8-6 act this way, but are good enough for 2133 7-10-7 ~1.7-1.75v IIRC, after that I have to move to 8-11-8. Those are some type of PSC

[Don_Dan]

That was fast! Don't you run Memtest before booting to Windows?

If they clock similar to PSC they're definitely some kind of BDxx, either bad BDBG or (normal) BDSE.

Sometimes, but usually not. Running Memtest every time I change settings would be a little bit of a hassle...though I do have it on a bootable flash drive.

Win XP is a lot easier to corrupt than Win Vista/7, I've corrupted probably 7 installs of XP and Vista/7 3 or 4 combined. With those though, either the installation disc or built in you can fix it in like 5 minutes

It is a little weird.
6-8-6-24 1600 = 32M pass 1.67v, still need to try a little lower
6-9-6-24 does not work at 1866, nor does 7-9-7 up to 1.75v
7-10-7-27/7-11-7/8-10-7/7-10-8 boots fine at 2133, IIRC as low as 1.65v, but won't pass 32M up to 1.75v.

I had a hard time passing 6-8-6-20 1600 too, tried up to 1.7v for that.

[hiwa]

Beepbeep they are all bbse if thats was the question my trident 16000c9 is exactly like urs, mine are green pcbs but nothing change btw black and green.

Try cl9 they are really sux at cl8 my kit is 1023 so very close to urs.

[Don_Dan]

Sounds like some weak ICs, but I'm not really surprised, the kit is only rated for 1333 7-7-7 after all.

They are some oem bbse ics and weak on ib, they were crazy on clarcky for high freq.

[Don_Dan]

Are you sure they are BBSE? Even the weakest Elpida Value BBSE I have seen on 1333 CL9 sticks can do 1066MHz 7-9-7 ~1.70V. The production date of the ICs on this kit is also too late for BBSE in my opinion. I think they're some kind of Elpida BDxx IC in OEM form, they were not even binned for BDBG or BDSE most likely.

[hiwa]

I remember ripjaws with bdbg and trident with oem bbse at that speed, and no man i have 1600 7-7-7-21 ripjaws cant do 2133 9-11-9 with even 1.80 and they are marked bbse.

[Don_Dan]

That bad?? I thought you get all the good stuff from G.Skill...
I think BeepBeep should try tRCD7 at 800MHz, if they can't do that as well, I'm convinced they are some sort of BDxx.

What were those Ripjaws with BDBG rated for? Trident/Ripjaws with OEM BBSE are quite common and mostly clock like typical BBSE as well.
