I recently purchased two 4GB Memory Modules to install into my desktop and am having with getting the machine to boot up.
My set up is as follows:
-Intel Core i7-2600 (LGA1155)
-ASUS P8P67-M Pro Mobo
-2 x 4GB DDR3 1333 - Team Elite
-MSI Video Graphics Accelerator
The existing Team Elite memory is plugged into A2 & B2 DIMM slots.
When I initially installed the Kingston memory into the remaining A1 & B1 slots, I would get a double boot scenario occuring wherein, the machine would start for about 1 second, seem to shutdown and then restart. I then upgraded the bios to rev. 3608 which seems to have stabilized the double boot scenario. But the machine still seems to hang after loading the (or at least partially loading) the bios. Everything reverts to normal when I remove the kingston memory.
Ok so I finally solved this. The main issue had to do with the fact that I was sold single-sided memory when I should have been sold double-sided memory. Apparently, the P8P67-MPro is not able to handle the memory chips used on the single-sided boards. The crazy thing is that both the shop where I bought the memory and the Kingston site claim that this particular part number (KVR13N9S8/4) will work with my mother board. It wasn't until I wen to the Asus site that I realized that the correct 4GB memory module is KVR1333D3N9/4G. The "G" at the end being the key difference.
This was a bit of a painful experience as I spent several days trying to solve this problem. At one point, I even updated the bios and temporarily disabled my machine due to a failed update (I actually thought I had bricked my mobo!) while I tried to get the memory working. I could have avoided this all if I had actually been sold the right memory!
