Not a problem, I went into the bios and changed the frequency to what it should be as well as the voltage which according to the sticker on the RAM itself should be 2.10v. After I did this though my computer started blue screening me every so often. The first time it crashed was the first time it has ever blue screened in the 6 months I have had the computer. I thought it was just a coincidence but then a couple of hours later it happened again.
I set the RAM back to its original 800mhz and everything was fine again. Then the other day I changed it back to 1066mhz and it began crashing again.
Unless this is just a really weird coincidence I don't know why it's happening.
EDIT: It takes a good couple of hours for it to first crash so maybe a heat issue? Even though it has a heatsink and I have case fans to keep everything cool.
Also my motherboard is definitely compatible with my RAM.
DRAM:FSB 1:1 ratio whas a good thing on DDR era, but with the DDR2 u can have a faster memory speed than FSB speed with no stability issue. Anyway i don't recommend to use this memory at 267-533 MHz DDr for the sake of 1:1 ratio. U have a better,faster,stable memory at this settings:
400MHz- 800MHz DDr ,4-4-4-12 timings , default voltage 1.8v. U may try to overclock this machine, then get the 1:1 ratio and rise together FSB and DRAM frequency. That will be a very good thing to do. Try at least a 333MHz x 11 FSB . BUT then again u will need an aftermarket cooler and good airflow case.
