The Basics:
The two 1GB modules are shown below, and they are remarkably unsexy. With just about every company selling their memory with heatspreaders pre-installed, it seems odd to receive some "bare". In addition to the lack of heatspreaders, there are no flashy colored PCBs, no blinking lights, and not even a camouflage paint job! Just memory chips on a green PCB... Like the good old days. The presentation is strictly business, and hopefully the performance is too.
 
The "front" side of each module features two stickers. A white one lists some product details and a serial number, while a silver one features the Transcend logo and the phrase "Lifetime Warranty" in a hologram. The "back" side of each module (see upper module in above right image) is blank. Each side features eight memory chips, for a total of 16 chips per module. The image below shows a close up of one of the chips.
Each module has the following markings:
JetRam
J12Q3AB-8
T0632M
S5005900PEBRB
In general you can look up the information from a memory chip and find more details on the features and specifications, which can perhaps provide a glimpse into the performance and overclocking potential. JetRam is actually a part of Transcend, so this is pretty much a proprietary chip, and I did not find any additional information online.
Using two different software applications I was able to gain some information on these modules, as presented below. The below left image shows what Everest Ultimate Edition 2006 has to say, and the below right image shows what SiSoft Sandra 2007 reports. The two programs concur on the basics, and show what timings SPD detects at various speeds. At the stock speed of DDR2-800 timings of 5-5-5-18 are reported, but the BIOS in the test system locked in on 5-5-5-15 at first boot. The BIOS only went up to 15, but the system booted properly anyway and I proceeded without problem.
