Incompatible RAM on my Asus B85M-G

[Polsus]

I recently bought a new motherboard (Asus B85M-G) and processor (Intel i7-4790K) to upgrade my machine. Now I've installed it and find no signal to my monitor. After trying several options and disconnecting everything i don't need, the system will boot on only 1 memory bank (in the DIMM B1 module). As soon as I insert a 2nd bank it won't work.
According to the asus QVL list my memory banks (2 GB Kinston KP223C-ELD - 3x) are not compatible.

Could this be the issue and should I by new memory or might the mobo be broken.

the haswell refresh cpu require bios update before they can run with your mobo!

Dear Chris, I did the bios update, and this partially solves my problem. I can now boot with 2 memory banks in the DIMM B1&B2. As soon as I put a memory bank in the DIMM A1or2 and I power up it seems the system tries to reboot constantly. The fans start up, go down, up, etc.
So the question remains. mobo fried (or the DIMM A banks at least) or incompatible memory?

on asus mb the ram goes a1 b1 and a2 b2 are the two banks. you should be putting the ram if the mb and guild is marked right into a white and one black ram slot. they should not be in the same color banks.

Dear Smorizio, tried that as well, but as soon as I put a memory bank into slot A1 or A2 (even 1) the fan spin up, down, up, down, etc, but no boot. Only if I put bank into B1 and/or B2 it boots.

http://www.amazon.com/KP223C-ELD-Kingston-1333mhz-Pc3-10600-Memory/dp/B00HJL6HVY is this your ram? looks like DDR3U which defaults a 1.25V rather than 1.5V . this may be the culprit.! additional voltage tweaking may be required that most probably isnt possible due to B85 chipset limitations.!

Chris, this is indeed my ram. So your advice is to by new RAM which defaults at 1.5V?

well if ram voltage tweaking isnt possible through bios then i cant see any other option other than buying yourself a new ddr3 ram kit! even if you could increase voltage, we cant be sure that they will accept it!🙁

Hi Chris, tried to tweak the voltage, but without results. I am going to the shop to buy a new kit. I will let you know the results later today. For now thanks for your support.

Hi Chris, new RAM installed, but still the same issue. Now I am sure my mobo is fried. DIMM B1 & B2 are working, but DIMA A1 & A2 are not. Now I do have 8 GB, so it is working at least. I will get back to the supplier to get a new mobo. Again thanks for your support.

thats unfortunate, hope the new one will finally resolve the issue!

check for a bent pin under the cpu. if there none also replace the cpu as the memory controller is in the cpu and not on the mb.
