Need help with RAM voltages etc

Hi, I just got help from here: http://www.tomshardware.co.uk/answers/id-2137349/prepare-watch-dogs.html

I have just received this set of RAM: http://uk.pcpartpicker.com/part/patriot-memory-pv38g160c9k

And I just found out what my actual motherboard is: http://www.asus.com/Motherboards/P7P55M/

And the RAM I had in my machine until now has a sticker on it which I assume labels the make and model as: crucial BP1138Y.F9. What I assume is rating information that I don't fully make sense of is also listed: 256MX64 DDR3 PC3 - 10600 UNBUFF

For some reason, if I try to boot with all 4 sticks in, it gets stuck on the starting windows screen, but with one pair or the other it is fine. I assume it something to do with voltages and other BIOS settings. Is there a hard and fast way to get all the RAM to work together (I don't like the idea of 4GB of ram sticks sitting around doing nothing), or if it is system dependant, then like, what SORT of settings should I tweak to ensure SOME kind of functionality. I read that different brands and speeds of RAM will in total, be limited by the slowest, is my old ram that much slower than my new set that it would be not worth using both sets at once?

Please let me know if I could provide any more information so you can help me out here. I imagine having all sticks in WILL slow it down compared to my new patriot RAM's potential, but is the slowdown really significant? I would happily accept a slight loss in speed, for more usable memory. I would like to use it all if it is possible and reasonable, as I often do a lot of memory heavy activities like 3D and 2D design and game making, video and photo editing, large memory overhead in browser due to hoarding of tabs (I have a data hoarding problem ;P ) and of course, games.

I will be grateful for help and advice, thank you in advance! =]

With the new sticks, should support them, make sure you have the latest BIOS, then go into BIOS enable XMP and select profile 1, should set the sticks up at 1600 for you, your older sticks are 1333...what you might try is once the new are stable at 1600, try adding the old and maybe try them all at 1333 9-9-9-27 and the DRAM voltage about 1.6

ok thanks for the response, I'm sure they're all really good numbers ;P but what do they mean and where do they go, and how do i test to make sure its stable? I assume you know already but my old sticks don't have any kind of heat dissippation, would those values be safe under that circumstance?

Ok so first, where do I find a BIOS update, and how do I perform the update? Is it something like, put it on a USB, boot into BIOS, and in some way, flash the update from USB?...

Once that is done, where do I find the place to enable XMP and where exactly do I set 'profile 1'? (I think I've seen several BIOS pages with some kind of profile option such as CPU and fan settings)

When you say set them all to 1333, does that include the new sticks and how will that impact their performance? what does 9-9-9-27 mean and where do i put those values? and how do i set the DRAM voltage to 1.6? I've seen the DRAM page in BIOS and theres like a million different fields that look like they might do something...

Sorry for all the questions I just want to make sure I do it right, if at all.

Thanks again
