Need help downclocking with SPDTool

I need a little help, I have 2 2 GB DDR2 800 MHz sticks, and no, cannot return them, . either one of them will work with a 667 mhz module in my MacBook (My school requires them, I would never buy a Mac, and I never have nor will, but I am making use of it while I am cursed with it) but not both, and I know why, crappy little board cannot handle downclocking two 800 mhz sticks at the same time, so I did some research, and a guy got them to work by editing the spd to downclock one stick manually, but I am not great with clocking and timings and such, so if someone could instruct me on setting the right values to downclock this stick to 667, or better yet, do it and post the dump file, I would really appreciate it, I am using Windows 7 64 Bit Home Premium (They can make me use an Apple computer, but not the OS) if that has anything to do with it.

Thanks in advance to any kind souls that give me a hand. I've uploaded SPDTool and the dump file for that stick, I tried to clock these myself a few times, downclocked to 333 mhz, and set timings to 4 or 5, but screwed something up and nearly lost the sticks. So I'm just gonna hope someone more knowledgable than I can help.

Nearly forgot, in case it helps any, these are the modules I got:

EDIT: Forgot to add this, the sticks I bought are indeed 800 mhz, the page changed after I bought them, but the rest of the information should be correct. I am positive that these are 800 mhz, so disregard what the page says, XD
