HELP!!! 780i Safe NB/RAM Voltages?

post #1 of 4
Thread Starter 
Hey I have searched and searched and searched and searched and I can't find a darn thing and it's starting to annoy me a LOT. I want to run my 4GB of BallistiX at 1066MHz, like they're rated. Yes, they're 4x1GB chips so I may run into issues but my cooling system is impeccable. I have an Antec Spot Cool right on the RAM, i've reapplied my NB/SB/MOSFET heat sink with AS5 and have taken off the rubber pads, and I have a wicked case airflow. What kind of voltage can I use with my NB and SB (SPP and MCP)? I have it set to 1.5v for the SPP and 1.675v for the MCP right now which are both just highlighted RED in the bios, but I am still unstable. RAM I am able to run at 2.275v/2.3v safely with proper cooling. Is running the NB at 1.55v safe with the fan at 100% and good case cooling, AS5, etc? I am getting really frustrated here... Any help is greatly appreciated!

Oh and I can't figure out how to find vDimm in windows with the REAL readings for it.

HW monitor gives pretty accurate readings for memory.

Ive found Nvidia chipsets also dont like 4x1gb of ram . (overclocking wise)
