Need assistance making RAM work with my MoBo

Helllo everyone. I'm new to the forums but have used this site for quite a while to help make choices on equipment & do research before buying. I generally like to build the best-bang-for-buck type rigs. I am a gamer & also use CAD software. I've built probably close to 150 computers (used to do small business IT consulting), but I never got really into the hardware side of things regarding OC'ing, voltages, and how things function on that basic level.

I built this rig about 2.5 years ago & it's still runs great. I am about to start playing a new game & doing some side CAD work at home & thought I would do some upgrades to squeeze another year or two out of it. On black Friday I found a good deal on the G.Skill ram listed below. I just looked at the base info (I stayed up really late to grab a Thrive tablet for $199 & the ram was an impulse buy). Well, I just saw that it was DDR3 1600 which I knew to be what I was currently running. I however did not think to check to ensure my MoBo supported the default voltage for the G.Skill modules.

When I installed them, the PC wouldn't post, it just gave me a power error & beeped. I forget the exact verbage. I also forgot that the MoBo was manually configured to 7.7.6.18 1.9v instead of on Auto. I updated my Bios last night to enable the core unlocking feature that was added to attempt to unlock my 4th core, while in there, I saw that the default timing for my mobo is the same as the G.Skill, but the lowest voltage it will configure to is the default 1.6. I can't set it down to the 1.5 that the new memory is listed to work at. I'm going to try to install the memory again & see if it will post, but I wanted to post up here & get input from people with far more knowledge than myself.

My question is, is there a way to change my bios settings or OC this memory to make it work with the higher voltage? It was pretty late last night when I was done getting the Bios updated, then reconfiguring my Raid settings to it would recognize the OS (running 2 WD blacks in raid 0). I haven't tried putting the ram back in since the manual timing/voltage settings got wiped when I flashed the bios. The MoBo is very OC friendly as I can configure everything manually with ease.

I posted links to everything on NewEgg for additional technical info.
The RAM in question:
G.SKILL Ripjaws Z Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9Q-16GBZL Cas Latency:9 Voltage:1.5V Multi-channel Kit:Quad Channel Kit Timing:9-9-9-24

Thank you very much for taking time to read my post & I hope there's a way to make the RAM work, I'd love to quadruple my ram & not have wasted that money on memory I can't use!

I attempted to edit/add some info. I am not running the current Muskin at 1666, i'm running it at 1333 at the specified timings & voltages. It has been extremely stable & I do not mind running the new ram at 1333 or OC'ing it. I just hope to make the new memory work with my rig. Again, thank you for your time.

The detault timings are the same as the new kit, however, my mobo only goes as low as 1.6v & the new memory operates at 1.5. I don't know enough about the settings to know if I can simply run it at a higher volt, or if I need to tweak some other settings along with the voltage to make something else work right or be in a correct multiple. Also, I can't return the kit because I took one of the module's head spreaders off to fit under my huge CPU cooler.

Did you get it working?
