So Many Issues!

Nothin's better than fresh install of 64 Bit Vista and 6 Gigs of RAM to play with right? Right! Until your 6gigs won't go up to the 1066 they're supposed to be at, and you can OC your CPU from 2.53GHz to 3.8GHz but you can't get your RAM passed 800MHz.... <--- Exactly what's happening to me! I have a 4GB Kit of DDR2 1066 RAM from OCZ which my motherboard picks up at the speed it's meant for and the timings. My other two gigs come from Kingston's HyperX line of products. They're also DDR2 1066. I didn't think that slight differences in timings and voltage would lead to this! Right now, my plan is to sell my 2gigs for $20, and then get another 4 totalling eight. My only question now is how do I check the RAM to make sure it's not DOA? Also, is 64 Bit Vista less open to overclocking? Normally I wouldn't care but I've got an Intel E7200 and an Artic Cooling Freezer 7 pro so I want the MAX I can get you know? Thanks for the help guys!

If it was DOA it wouldn't boot at all because it is Dead On Arrival! If you would like to check a working RAM module for errors with Vista just hit the START button and type MEMORY into the search box. You can then click on Memory Diagnostics Tool and let it go work for you.

What motherboard are you using?  And DDR Voltage?  Also, keep in mind, some motherboards can't handle high memory speeds, when all of thier memory slots are loaded.
