Yes DDR2-1066 is compatible with DDR2-800. The RAM has the SPD for 800 (400X2) in the RAM.

Most RAM will run at 1.8V for DDR2-800. If you RAM requires more voltave for 1066(533X2) you can up the voltage in BIOS.

what are some things to look for after installing memory?
like what should the voltage be?
Is the timing going to be the same?

After install notes, bios saw 4gb, windows saw 4gb, bios voltage after install were 1.9, sticks are 2.0 and 2.1, changed to 2.0, memtest failed instantly after 1 second on all 3 voltage settings, 1.9, 2.0, 2.1. timings were 5-5-5-15, here is link to ram.

You should list what motherboard, cpu, PSU, that you have to help readers get an idea of your system.

Reset the CMOS. Make sure ram timings are on auto and voltage is at 2.1v.

Have you tried the modules in different memory slots?
Is this a new build or is it upgraded memory?
