For a start, I set the timings of the memory to CL3 and clock
speed to DDR2 800mhz in the BIOS of my motherboard as some of the current memory
available in retail channel can do CL3 at voltages between 2.3v to 2.4v. I started
off with the middleground of 2.35v. Upon saving the settings and booting up,
my system managed to load into windows without a hiccup. So I ran a quick stability
test using SuperPi 4 Million and Sisoft Sandra Memory Bandwidth test. This pair
of memory went through these easily. Thus I ventured further by upping the Memory
voltage and the maximum clockspeed attained was 410MHz at 2.45v:

400MHz @ CL3-3-3-5, 2.35v

Now notice in the screenshot of CPUZ, the manufacturer of the
RAM mchipsets are omitted and not programmed into JDEC.
