Why not? They can be used with 1.65v 24/7 no problems there

I thought we weren't suppose to go over 1.475v

eBombzor well its 1.575v not 1.475v, and there are some kits with these same chips rated at 1.65v but its up to us to use the voltage we want with them
post #303 of 1055
That whole 1.475v myth originated from that really old TPU review...I say forget that and run 1.65v happily, as Cygnus said. thumb.gif

Which was nothing more than an opinion to begin with.

Exactly, but people tend to pass things like that as fact once they've read it multiple times. thumb.gif

Ok thanks guys I ran my 1229 kit at 2133 9-10-10-27 @1.5v so I was scared it would crap out on me or something.

I've done short term (24 hour stress) testing at 1.65v without any ill effects, but I doubt anyone has done the kind of exhaustive testing that would convince me that such voltage is safe 24/7 for the majority of these DIMMs.

I actually use my memory, and I need it to be stable, in more adverse conditions than most are used to (my ambients can reach ~40C and my systems are often loaded for months on end).

Depends on how much time is needed for ~2000% coverage.

Nothing is a sure thing. There are likely some errors that HCI would find faster, but I do believe Prime95 custom Blend is typically going to be better (as in finding more errors in less time).

I use both.

20nm IC have been in mass production for a while, I just haven't seen any DIMMs with them, yet.

For density, absolutely.

For overclocking, no way to know yet.

More voltage doesn't always lead to superior OCing, and 20nm ICs will likely be more fragile than 30nm parts.

Almost certainly completely safe.

Lots of interesting facts here. I knew about the 20nm process a while back but have not read anywhere on the internet about seeing them in the wild.

I will try to be aggressive with the OC and try to push for 2400mhz @1.5-1.6v at 11-11-11-28.

On a separate note, I just found a good friend who is willing to sell me 2 670's for 500 shipped. I'm pretty excited if that deal pans out.

Yeah, go higher...1.6v is not likely to cut it. I'd try between 1.6 and 1.7v for 2400mhz with those timings.
And, whoa that's a good gpu deal wink.gif

It could i am runing mine at 2400MHz 11-11-11-28 2T with 1.55v
