I have that exact RAM and it rund FLAWLESSLY in my RIG. I am a big fan of mushkin, they produce high quality products. It runs at the proposed timings, 4-4-3-10 which is very respectable for DDR2 Ram. I have mine slightly loosened as to not interfere with my E6600 Overclock. The Micron D9 chips run cool. At one point my Cpu and Ram were 'linked' and I found that my RAM couldn't handle anywhere over 900Mhz, but IMO nobody really needs to go anywhere past that. Since I bought my 2 Gig kit, the price has dropped significantly and I am going to pick up a second pair shortly. This is inexpensive RAM that I would recommend to anyone. I say go for it.
You should be able to take the Micron D9 chips above 900Mhz, mine have reached 960Mhz while maintaining 4-4-4-12 timings with a .05v addition over stock(total of 2.25v). Even though mine are a different manufacturer, it's the same D9GMH chips in it. You should be able to take any Core2Duo to 3Ghz+ on the Mushkin without issue.
I have this 2g kit and it goes nicely with my p5k deluxe and q6600. I have heard of some people having problems with heatspreaders slipping/shifting when installing, but it didnt happen for me.
The only problem i had was that i had to manually set the voltage so that my RAM would run in dual channel in the correct slots. But that may just be an issue with the P5k deluxe.
I also say you should go for it.
You can also go to the mushkin forums if you have issues, they're pretty helpful.
