I've got two of these kits (total of four sticks, 4GB) working like a champ in my IP-35 Pro. They were purchased at an incredibly low price from OcUK. The SPD data is a bit pants and I manually set the timing to 4-4-4-12, 2T. The voltage was increased to 2.1V as recommended on the packaging. If you leave everything on Auto then the IP-35 Pro sets the timing to 5-5-5-18 at 1.8V.
I hope that helps someone out!
