Question Trying to replace RAM on a GA-X48T-DQ6 Motherboard.

[Dystynct24]

Hello, I hope someone out there will be able to figure out the issue my dad and I are having because we are stumped. My dad has an old system(built in 2004 old). It originally had Windows XP on it that was upgraded to Windows 7. Currently he is running 12 gb of RAM, 2 x 2gb, and 2 x 4gb sticks. The Motherboard is the GA-X48T-DQ6 (i'm assuming rev. 1.1). According to the specs we were able to find online, this motherboard should be able to support 4 x 8gb sticks of 1600 or 1866 DDR3 dimm ram. The original RAM is 2 x 4gb Corsair Vengeance, and 2 x 2gb of Kingston Hyper-X (Images below). The new RAM is Patriot Viper, we have 4 sticks of 8gb 1600 MT/s and 4 sticks of 8gb 1866MT/s. After attempting to install both groups of RAM( We attempted with 1 stick, then 2 sticks in their proper configuration, then all 4 slots filled, then even 1 stick in the 4th slot.), the computer will not even reach POST, it will turn on, and then shut off immediately, and then begin a boot loop of failing to POST, or stay running for more than approx. 5-10 seconds. We cleared the CMOS, tried loading Optimized Defaults in the bios, but it did not alter the issue in any way. Does anyone have any idea as to why this system will not accept this ne]w ram? Any help would be greatly appreciated! Thank you.

This is the RAM, trying to insert the images was being difficult.

Welcome to the forums, newcomer!

You should look at 1.65v rams for your board. 1.5v sticks of rams were sticks used for the first gen and onwards Core i processors from Intel. I have a 996982 kit from Mushkin Redline that worked out of the box;

on my Rampage Extreme X48 chipset board, which I've retired a good 8 years ago.

If you're looking for a ram kit for your X48 platform, look at the board's memory QVL. As for your motherboard;
The Motherboard is the GA-X48T-DQ6 (i'm assuming rev. 1.1).
Look at the bottom left hand corner of your motherboard to see the PCB's revision number.

If you want to pursue higher speed memory, then you will need to look for 2.0v ram kits but that won't net you much in terms of performance while on the Core 2 platform. They worked best while on DDR2 ram, IMHO.

While Gigabyte only supported 8GB on that motherboard, 16GB works fine. I have 16GB of DDR3 in every X38 or X48 board that takes DDR3.

X38 and X48 chipsets only support up to 2Gbit memory chips so sixteen of those gives you 4GB sticks maximum. And this also tells you 4GB sticks with only 8 chips on them won't work because those would be higher density than is supported by the chipset.

Keep in mind that if you manage to run that DDR3 at 1600, that it only takes a single channel of it to fully saturate a FSB overclocked to 1600FSB at 12.8GB/s. The additional bandwidth from dual-channel can only be taken advantage of if you are using integrated graphics, which X38 and X48 never came with.

Shocked how much detail there is in the fine print. Thank you.
