OCZ Gold XTC PC2-6400 4GB 2X2GB DDR2-800 CL5-5-5-18 DDR2 240PIN Dual Channel Memory Kit

after installing my pc would boot then get to the welcome screen and freeze.
I had to do a hard boot.
after doing this a couple of times I pulled the OCZ memory and rebooted without any problems, I then shut down and swapped the corsair out with the OCZ and fired up the pc and it froze again so I know it is that memory, but just to be sure I looked at my Motherboard manual and it says that I can run upto 8 gb ram at a voltage of 1.8 ( this is where I am lost because I don't know anything about these kind of things) I checked the voltage of the corsair mem ( on the lablel) it says 1.8 but the OCZ doesn't tell you anything about volts and after a bit of searching I found this 1856351&forum=101&product_id=23482&msgcount=2&over clockid=0#msg1856351 so could thisd be my problem and if it is what what is your advice on fixing this? I went into the bios on my board but am not sure how( if I can) change this to the proper volts.
this is my board GIGABYTE - Product - Motherboard - Overview - GA-P35-DS3L (rev. 1.0)
Hit "Del" as the PC starts, to enter BIOS. Now, hit Ctrl+F1(at the same time).I usually scroll down one or two sections(around "integrated peripherals") before doing this, as it can sometimes take a few tries to get the timing right.. for hitting both keys at the same time. By being down a few sections, you will know when you hit the keys right, because they will pop back up to the original top row("standard CMOS features"). Now that that's done, scroll down to the bottom,"MB Intelligent Tweaker (M.I.T.)"..hit enter. Scroll down to near the bottom of the page, and where it says "System Voltage Control"..enter, then set to manual(i use the +/- keys on the far right of the keyboard to adjust values). Now right below that is "DDR Overvoltage Control"...change that value to +.2V, which will give the RAM 2.0v. Press F10, save and exit. if it reboots okay, then try and run some CPU/RAM intensive apps(Prime 95 is good) to stress the RAM, and make sure it's stable. If it's still unstable, or didn't even boot up.. reboot, enter the BIOS again, and set the DDRv to +.3v. repeat the past steps and reboot/test. If it still isn't stable/doesn't boot.. try once more, setting DDRv to +.4v(for a total of 2.2v). repeat all steps. If that doesn't stablize it...then it's time to RMA some RAM...there's a few possible reasons: 1. The different RAM sets don't play well together. 2. Your motherboard doesn't like one of the 2 sets of RAM. 3. Your motherboard doesn't like 4 DIMMS(sticks) or 8GB/RAM. GL
