Is it true Intel can't support ram with 1.65 volts and higher? - Page 2

post #11 of 15
Lol no, 1.65 is the standard voltage for DDR 3 Memory Modules as well as Intel's Integrated Memory Controller in i3/i5/i7 processors.

You're fine, no need to get new RAM just yet wink.gif

i myself have run over 2V testing, and up around 1.75v daily.

Back in the i7 1st gen days the common issue was that if you didn't keep QPI voltage within a certain range of the DIMM voltage (I believe it was 0.5v) you could damage something, but as long as you raised that voltage you could go above 1.65v for the DIMMs too. Default QPI voltage tended to be 1.15v So if you did 1.2v for QPI/IMC voltage and 1.7v for DIMMs you would have been fine. I'm not sure that still applies now but it might have been where your friend got his ideas.

I run 1.7v on my rated 1.5v 2133Mhz ram. No problems yet.
