Please help identify these memory chips (DDR2?3)

(1/2) > >>

Yansi:
Hello,

out of curiosity I've done a small teardown of a bit of professional video gizmo, to get an idea how stuff got done in there.

The main brain is a Cyclone III FPGA,  using three memory chips. I'd like to know what type they likely are (to estimate the bus throughput they may have). Please find below a photo of the main PCB.

I guess these may be either DDR2 or DDR3. But I've failed miserably trying to google the cryptic alphanumeric codes on the chips. Manufacturer is likely a Micron.

Thanks for any hints

//EDIT: Cyclone III seems to support only DDR2, so DDR3 they are not. Still I'd like to know what the bus width and capacity of these may be.

BravoV:
The legendary Micron D9 series ... DDR2.

Yansi:
Why legendary?

In PC overclocking's scene back in the days of DDR2 RAM.

BravoV:
Its like current Ryzen's DDR4 RAM so called Samsung's B-die ... but you wont get it if you're not into PC overclocking, especially overclocking the RAM.

That D9 was well known to be a beast capable of crazy speed and can bear RAM overvolting, it used to be popular among extreme overclockers.
