Looking for some advise on memory upgrades. I have a stock HP m9040n specs. below. Crucial recommends DDR2-1066 for my computer. However, all the documentation for the computer states the mother board will only support DDR2-800, and DDR2-667. I would like to utilize the faster memory. I am concerned that if I purchase the faster (more expensive) memory, the mother board will downgrade the memory to DDR2-800 wasting money as well as memory.
I did email Crucial and while I appreciate the response I received, it did nothing to alleviate my concerns. Basically Crucial responded with the memory will work and stated the "Guaranteed Compatibility"
Looking for a little better explanation on if my computer will actually utilize the DDR2-1066, or just stick with what the documentation states and purchase the DDR2-800. Thanks for your time and Merry Christmas.

Thank you for contacting us today. I pulled up some information on your system and it does appear that your system can utilize the full speed of the 1067 mhz RAM based on the front side bus speed. If you are wanting the fastest RAM for your system I would recommend the 1067mhz RAM found here. Please let us know if you have any other questions or concerns about this upgrade.

Thanks for taking the time to respond. Is your recommendation based upon the front side bus speed of the CPU matching with the capabilities of the mother-board?? If so, any idea why Asus and HP state the mother-board will only support up tp DDR2-800 ?? Thanks again

My recommendation is based on the CPU and front side bus speed as those are the limiting factors of the RAM. I believe that HP and Asus are reporting the system needing 800 mhz speed RAM because they most likely did their testing when 1067 mhz DDR2 was not available yet. Most companies will report the recommended RAM when the system is released, but they do not do any further testing as new RAM is released.
