Using RAM with 1.65V with a Haswell CPU, should I get 1.5V RAM?

Here is the pcpartpicker list:

Right now I have 1.65V RAM and my computer would BSOD or freeze randomly. I haven't made any changes to the bios yet. I am not even sure if my mobo can handle 1.65V RAM because on gigabyte's site (http://www.gigabyte.com/products/product-page.aspx?pid=4518#sp)

Under Memory it says:
"4 x 1.5V DDR3 DIMM sockets supporting up to 32 GB of system memory"



I think I can enable XMP to get the RAM to work, but I am wondering if this is a good idea.

Thanks.

Wait, so your saying my Kingston Hyper X Black 1600mHz is crap because it need 1.65v to run at 1600mhz? could it just it's older memory and 1.65 was a norm back two years ago.

Although I admit that I have problems OC'ing with the XMP profile, on 4670k and asus hero board. I also think I just have a crap chip. Cause I can't get anything over 4GHz no matter voltage I give it. stock it at 1.216v

In this case I would get different ram There is NO need for 1600 MHz ram to EVER be over 1.5v the only reason that is 1.65v ram is that is it crap ram they are raising the volts on to get it stable. Find a 1.5v set and enjoy. Won't harm your system you're just getting inferior ram for the same price. :)

1866 and under - stick with 1.5 sets, higher voltages is often indicative of weak memory ICs, when you move up to higher freqs 2133+ 1.6-1.65 is perfectly fine, it's anticipated you are OCing the CPU

Well actually, yes. If 1600 mhz memory needs more than 1.5 volts, its not what I would call quality parts. Likely parts that were originally specd at 1333, and needed a voltage bump to get them to 1600. IMHO, Kingston is.....how to say this politely, memory for folks who are more value minded.

90 bucks for 8GB is not value minded. But it's served me well for over 2 years... with out any problems. Until I got this Haswell chip. I'll just switch it out with my wife's corsair ram that run at 1600mhz at 1.5v she'll never know.... lol and see if that make any diff.

Two years ago the standard for 1600 was still 1.5, Kingston and Corsair both continue to slip out set at 1600 that are 1.65, though only about 13% (and shrinking) of 1600 DRAM available today requires 1.65, many of these (IMO) would be better off sold as 1333 with tighter timings, but they need o get rid of the ICs they have have and with 1600/9 basically as entry level, think that's what they are putting them on
