Ah ok, that video was very helpful. So you found the option to switch it to DDR2 1066 (which your board did do), your computer just isn't stable at that setting so it can't even launch Windows.
You probably have 1 of 2 problems (or maybe both problems).
1) Your timings are set too tight for DDR2 1066. At DDR2 800 speeds, your timings were probably something like 4-4-4-12, or 4-4-4-15. If they're left on Auto while the memory setting is manually changed, there's a possibility that they are Auto loading at the tight 4-4-4-12 timings. Manually loosen them to 5-5-5-18. Those timings are in the order of CAS Latency – tRCD – tRP – tRAS, although your board may call them something different (just post a screen shot or another video of your timings options and we can help, but they're usually the first 4 anyway). OCZ memory is very picky about the tRAS value (the 18 in 5-5-5-18). Most memory run at either 4-4-4-12 or 5-5-5-15, but OCZ is usually only stable at 4-4-4-15 (DDR2 800) and 5-5-5-18 (DDR2 1066). The tRAS does not have a big impact on performance so don't be afraid to loosen (loosen means increase it) that a little more.
You'll also want to set the command rate to 2T (options are 0T 1T 2T). And set the tRC to something over 22 (like 23, 24, or 26). There might also be an option for tRFC. If so, there should be four tRFC values, labeled tRFC0, tRFC1, tRFC2, tRFC3 representing each of your four memory slots. Make sure they're all set to the same value, like 105ns (or the next highest number if it's still not stable at 105ns).
Any other timings just leave on auto. If you need help with these, another video showing your timings options, and then individually clicking on each to show us the options available to each timing would be very helpful.
2) Your memory voltage may be too low. The option is usually called DRAM voltage but might go by other names. Look up your specific memory set and find out what voltage it needs, then set your DRAM voltage to that value (or maybe even 0.05v higher). Right now your memory may not be receiving the juice it needs to run at the higher speeds.
Finally, it's possible that one of your sticks just cannot operate at the advertised speeds, timings, and voltage. So if you try everything above and it still doesn't work, then try running your computer at the proper timings, voltage, and DDR2 1066 speeds with just one stick of memory in at a time. Test both like this to see if maybe there is a problem stick.
EDIT: The memory's required voltage and 4 most important timings are usually on the sticker on the memory, so just pop open your case and take a look.Edited by durch - 9/22/10 at 6:59am
