Help finding manufacturer of DDR2 memory

[GiGaBiTe]

So my uncle gave me these two sticks of absurdly generic DDR2-667 memory. So generic in fact, that I can't find the MFG of them. There's a sticker stuck on it saying "WARRANTY VOID IF REMOVED", but I have a feeling it's a gimmick, along with the shady memory.

I've scoured the net searching for the numbers on the chip without success and is wondering if anyone else here could have a hand at it.

The BGA RAM chips on the stick have:
"RC12T08CA0-53EC"
"0649" (week 49 of 2006)
"YEJZ15XXC"

And the stick has this number printed on the VOID sticker:
"6464D28N8RA667T5"

I have a feeling it's probably fly-by-night chinese wofat(tm) memory that was probably illegally made in some illegal factory with chinese slave children getting paid 0.001 cent a day, but I'd still like to know regardless if possible.

Can you find any FCC ID on it?

[Tom Maneiro]

AFAIK, RAM sticks don't need FCC certification, so you won't find FCC IDs on these.

Modern RAM ICs are often rebranded/rebadged by those shady RAM "manufacturers", so the true identity of the chip remains as a mystery on most cases. For example, my Corsair DDR2-667 sticks on my laptop have Corsair logos and part numbers on each memory chip, but we know that Corsair does not fab RAM.

Isn't there a logo on the chips, anyway? Or just that text without anything else? If that's true, well, kill 'em with fire

The only number on the PCB (besides marks showing what various traces on the PCB are) is:

"B08AOS"

Besides the big "RC" markings on the individual RAM chips themselves, I'm clueless.

[Tom Maneiro]

Do you have a PC for testing those modules? If they're not dead, CPU-Z or Everest could tell the RAM manufacturer from the SPD data.

In the meanwhile, i looked for similar part numbers, and found this older DDR part:
RC56D081TA0-27BC

...it's a part number from "V-DATA", AKA "A-DATA", AKA "RAMos":

According with [1], it seems to be a rebadged Samsung part (if you have tons-o-money like Apple, or if you want cheap sub-standard parts, you can order Sammy to print whatever you want on the ICs, like "KickAss Generic RAAAAM" )

Anyway, where is my Mr. Blurrycam/cheap greasy scanner shot? Samsung chips have a unique font for the lower IC serial code (see those V-Data sticks and compare with any Samsung RAM chip picture) - if the font matches, you have some cheap Samsungs there.

I sacrificed my Win2k3 server's 173 day uptime to test one of the modules. It must not be the bad stick because it's been running fine for 2 days so far, just really slow since it's down to 512MB instead of 2 GB.

I looked at the SPD data and there was no information in the "manufacturer" field (it was greyed out)

As for mr.blurrycam(tm), I got a 12.1MP camera for my birthday and it takes nice 4000x3000 pictures with plenty of detail. These are resized for sake of not breaking everyone's screens:




V-DATA may indeed be the MFG of these RAM chips.

But will it blend

[Tom Maneiro]

Yup, those look like relabeled Samsungs These are the typical Samsung IC fonts.

Here is the homepage of VDATA ADATA: www.adata.com.tw/

No fancy MFG stickers and bogus SPD data means that these are some OEM flavor.

I was bored while doing Windows Update and tried looking up the memory again, and found the manufacturer of them.

www.ramostek.com/

Korean fly-by-night(tm) RAM company. Contacting them results in "550 undeliverable" email errors, fail.

"We deliver happy smile to customers"

My computer does not want a happy smile, it wants RAAAAAAAM

Since they're in Korea, this confirms that they are another Samsung mafia rebadger.

[TheMVRules]

"RAmos: Into your memory"
"RAmos way: Best way"
"We deliver happy smile for customers"

The site was crappy.

[Tom Maneiro]

Funny enough, "Ramos" is a very common surname in Spanish-speaking lands...

There is also a "English" button hidden under the Flash-y menu bar - if you're in Firefox, use Firebug to reveal it... just to figure that it's just a non-working decoration

I neither want RAmos nor any Mr. Ramos in my memory, that's for sure

EDIT: This is their hosting provider:
router.co.kr/new/main/main.html
...aptly named "Router"

[TheMVRules]

Router?

Worst. Name. Evar!
