Is 1.66volts safe for tripple channle DDR3

hi was wondering if 1.66volts is safe for triple channle ddr3

Assuming the ram can handle it you'd be ok in an AMD system. You'll burn out (literally, scorch marks and all) if you try this in an Intel system.

Not really. Conroe/Wolfdale/Nehalem can handle it, but Sandy Bridge would break if the voltage is higher than 1.65v (safest for SB is 1.5v)

S775 can handle 1.65+? Pretty sure all core chips can't. (1156, 1366, etc.)

My first Nehalem burnt a memory channel after operating at 1.66V for a few weeks. Luckily, Intel replaced it under warranty. The Intel guy I talked to at that time told me that 1.60 V was the maximum voltage that the CPU can take.

Right. Nehalem is a core series arch, and not to exceed 1.65 from all I've read. (the new SB arch says not to go above 1.5!) But Conroe and Wolf would be original series Core arch, and on the S775. Now that its been mentioned I don't remember hearing anything about 1.65v for that series. It's probably fine as the memory controller back then was on the motherboard so you didn't have this issue. So Conroe and wolf can handle it, but Nehalem can't. (or any other intel CPU where the MC is on the CPU rather then the NB.)

Yes Intel says over 1.65 will potentially damage the chip. That said .01 over shouldn't hurt the chip as long as the difference between ram voltage and qpi/dram is .5 or less.

Most boards run 1.2v qpi/dram by default, so unless you're running insane ram voltage you're good there. If it worries you, just run your ram at 1.64 or 1.65 if the mobo lets you. Mine is at 1.64(i7 920) for about a year or so, didn't ask the previous owner what he ran. The ram is spec-ed to 1.65, so I'm guessing he used 1.64 or 1.66, my mobo wont do 1.65.

I highly doubt memory companies would sell triple channel 1.65v kits if it was going to burn chips out, it's all about proper setup.
