Since you are stable no problem at all. In fact when you undervolt you gain both temps and power consumption. You can also try to undervolt your cpu if you are at stock speeds or even slightly oced.

try it and see if your RAM can still run at 1600 stable. i dont see it doing any damage if you do. also 1.65V is perfectly fine so i would just keep it at that if it were me smile.gif

Yeah, simply because incase it's not and in testing it seems to be, the data loss can be pretty bad.
I'd suggest to just leave it too, they come at 1.65v stock for a reason.

Ooh folks, I've just been reading how Ivy Bridge doesn't like 1.65v - bad for the memory controller is what they say.

I got 4 GB of HyperX 1.65v 1600, and 4 GB of Mushkin 1.5v 1333 8-9-8

The mushkin goes down to 7-7-7 easily so I don't know if the extra Mhz of the HyperX is worth it.

I'd get more of the Mushkin but it's a bit hard to find an exact match, and there is a lot of HyperX around at good prices.

Samsung greens is some nice insanely cost effective RAM ...IMO the best in its class...stock timings are almost irrelevant because they overclock so freakin nuts. i've brought mine down from 1600 11-11-11-28/1t to 8-8-8-22/1t and i run them 24/7 at 1866 9-9-9-24/1t/ 1.385v

Yeah, Intel specify 1.5v for Ivy and 1600MHz.
1333 will work, I had problems when I was running a generic 1333MHz 1.65v Corsair set for a bit.
You'd be better off trying to run the HyperX with less voltage (as you initially suggested). Upon a quick investigation of this myself I am now neutural to the whole 1.65v thing on Ivy thing. I'd suggest trying to run the Mushkins at 1600 8-8-8 maybe, they should be fine if they can do 1333 7-7-7. (@ 1.5v of course)

OK, thanks, noted, I'll have a look at those. I just tried clocking the mushkin up to 1600 but it wouldn't go.

So I'm looking at another 4GB of HyperX which is almost exactly the same model as what I have already - but has a slightly different power rating.

The kit I have is 2.160W, the one I'm looking at is 1.800W - would this matter if I used both on one board simultaneously ?
