Hi, I really need some advice here because I am going crazy! I have an older setup (but still good!) running an i7 920 on a Gigabyte EX58-UD3R. The mobo manual says it supports 800/1066/1333/2000+ memory but I don't really expect that to be literal (unless maybe it is which explains my problem).
My setup for the last 6 years has had 2 x 2GB DDR3 2000 G.skill sticks from Newegg (click). I have had them running in dual channel no issues.
I decided I wanted to upgrade my system and run triple channel 12GB (3x 4GB modules). I decided to purchase DDR3 1600 G.skill sticks also from Newegg (click).
(Note, I wound up buying a single stick and set of 2 which gives me 3 identical sticks.
I assumed that the mobo would just downclock the RAM to 1066 as that is what the i7 920 can run at (and I'm not overclocked for the sake of this discussion) and it wouldn't matter that the mobo "doesnt support" 1600.
Now is where things get bizarre. I populated the mobo with 3x 4GB in proper 3 channel configuration (I am 100% positive) and no boot. I systematically remove and swap the sticks around thinking I have a bad one. Well, I find 1 stick that works fine, in any slot. The other 2 sticks will not work even when by themselves. So I assume I am so unlucky that I got not 1 but TWO bad sticks so I get an advanced RMA replacement. So now I have 2 brand new sticks. NEITHER work! What?!?!? How can 1 stick work from the original set but now I have FOUR bad sticks. No I don't buy that at all.
Moving on, I keep the working 4GB stick in DIMM 1 and populate the other DIMMs with my old 2GB DDR3 2000 sticks. Viola, system boots up and says I have 8GB total in triple channel (even though its mismatched.
Therefore, I can conclude that none of the DIMMs are damaged and the DDR3 2000 will work in any slot in any order demonstrating those sticks are definitively good. For good measure I even re-seated the CPU and checked for bent/broken pins of which I found none. The only thing I notice about the new RAM, other than being DDR3 1600 is that they are 1.5V whereas my old ram is 1.65V. I also updated BIOS to the latest version which did not help.
Please help me!
