Backstory: My SATA ports went out on my Gigabyte UD3R. I decided to purchase this new motherboard, and I received my first one in the mail. I went for the install, and I did not post. When I booted up the system, the heatsink fan would just twitch every 2-3 seconds. No mobo LEDS or anything.
I went through all the steps of troubleshooting, but I heard 0 beep codes, could find nothing shorting my mobo, etc. I decided to RMA with NewEgg.
I received my replacement Rampage III Formula. I installed, and I had the same problem. I decided it might be that I had screwed up a piece of my equipment. I decided to reinstall my Gigabyte UD3R (even though I could not boot from my HDD) and see if I would post. It posted on my first try.
I called Asus, and they requested me to build back up my Rampage III formula. I'm running low on Arctic Silver 5, and I need to RMA ASAP. I don't think I can wait for shipping a new container of Arctic Silver 5.
So my question is: does this sound like a memory/motherboard incompatibility problem? Mushkin no longer makes this memory, so they are not on the supported memory list in my Rampage III formula. However, there is a post on Newegg feedback on the memory ( http://www.newegg.com/Product/Product.aspx?Item=N82E168...) where someone posted using my motherboard on first try.
The memory that you have listed is DDR 3 240 pin and while it is better to run the memory at a lower voltage it shouldnt be an issue of no memory detected. I would contact Asus tech support and see what they say. The X58 chipset is does support memory within that range and specs.
