I have two sets. Some sets have D9 DKX and apparently some don't. My first set was made in USA and my second in China. I have yet to manage getting the heat spreaders off and actually verify what the IC's are. They both have 2.35v stickers on the sticks I think my 1st set (USA) is a little stronger then my second (China). My first set could run DDR2-1000 (1/1) at 4-4-4-12 with around 2.3v on my TPower. I've also been able to run them 5-5-5-15 DDR2-1200 (333/800) with lower volts on my DFI UT and Gigabyte UD3P.
