I just got these sticks last night. I am running them on an Asus P5K with a Q6600. I had no problem at all getting them working at DDR1000 5-5-5-15 with 2.0v. One thing that I thought was extremely weird was how easy to get the heatspreaders off it is on these sticks. I wasn't even planning on ever removing heatspreaders again, because about a week ago I tried removing them from my GeIL 6400 2x1GB sticks.. When I did this 3 IC's were stuck onto the heatspreaders. On this memory however, I took one of the sticks out to put it into a different slot, and the heatspreader came off while trying to remove the memory. I could easily slide the heatspreader off the second stick without using any real force. Is this common on these sticks or are mine just like this?

Anyways, I was wondering what subtimings you guys can use for DDR1000, as I am trying to tweak them and im not exactly sure how tight I should start out at. The memory seems great though, I am extremely happy that I bought these.
