Strange Failed POST w/ EVGA 780i FTW and 2 kits of TWIN2X4906-6400C5DHX

Here is the link to the thread about compatibility for my board: http://www.corsair.com/configurator/product_results.aspx?id=393384

 

I have 2 kits of the ram mentioned in title its either c4 or c5 i can check if needed.

 

I used my board for over a year just fine with one kit in. I decided to get another kit and bump up to 8 gigs as i run vm's. I will get straight to the details.

 

Each stick works individually to boot the system.

Each stick works in any slot on the motherboard individually.

Any 3 module combination works in any 3 slots.

As soon as the 4th module is inserted I get memory post code or c0, 18, 10, 02. One of those depending on my memory config in bios.

 

I have tried raising the voltage on my memory to 2.0.

I have raised the voltage on my NB, SB, and MCP by .2.

I have played with timings from default 5 5 5 18 2t to looser like 5 6 5 18, 5 6 7 18, 5 4 6 18, etc.

I have tried in combination with the last step setting the clock to 667 from 800.

 

I do not know what else to try and I am desperate to get this working, hopefully without sacrificing clock speed.

 

Any help is greatly appreciated, I can give you as much info as needed.

 

Thanks in advance,

 

Nick

 

*EDIT: If this gets no responses for a few days straight do I have permission to post it in Memory compatibility section?

bump? Please it is important that I resolve this :sigh!:

Can you post ALL of the information from the stickers on each pair of modules? Pictures are great if you can post them.

 

What specific voltage have you tried on the memory controller?

 

Have you tried setting the memory speed to 667?

[poiZin]

I have tried the speed of 667. I can provide you with a picture either tonight or tomorrow. At that time i can give you the specific voltage i tried with the MCP.

 

Thanks agian for your response!
