I have a gigabyte x58a-ud3r motherboard & I have been having issues with the ram running at 1600 mhz. I have adata 1600 ddr3 that is advertised as running with timings of 9-9-9--27 with a voltage of anything between 1.50-1.75. Now heres the problem if I place 3 strips all in the "WHITE" slots I can change the ram timings to what there supposed to be with no problem "BUT" I have 3 other strips (there all adata ddr3) that all work (I've tested them all) 2 of the strips are the same type of ddr3 & the third appears to be the same as it has the same markings on the label but has a voltage of 1.75. No the problem begins after the initial 3 strips of ram are placed all in the WHITE slots, then when I go to place "any" of the other 3 strips in any of the remaining 3 BLUE banks when I boot the computer up I get the "detecting ram size/amount" message & it shuts down, but after 3 boot up cycles it does go to desktop on the 3rd boot. I have tried placing the 3 strips ALL in the blue banks and then adding the other strips into the white banks also & still same result. Now from what I've read both on here, on the web (looking up adata ddr3 timings,etc) and on tweaktown forums, gigabyte forums,etc this appears to be a voltage issue to which I have tried working with the voltages to no avail either. I do remember reading an older post that said which bank to place your forth strip of ram in once you have the intial three in but can't remember nor can I find that post, not that that may help as I'm sure this is strictly a voltage issue. Can somebody please help me out here I'd really appreciate it all.
