A closer look
Each module has a sticker on it, which gives the rated speed and the stock timings. The rated timings of 4-4-4-12 are the standard speeds of JEDEC DDR2.
OCZ's new heatspreaders are able to keep your memory temperatures down, even during overclocking, or with increased voltage.
A thin thermal tape holds the heatspreader in place. Is it very thin, so you can see the memory chips shine through.
I'm not 100% sure but as far as I know this PCB is made by Brainpower who are known for their quality.
