I am using a 2500k and a Asus p8p67 mobo, I purchased some RAM (this one to be exact http://www.newegg.com/Product/Produc...82E16820145260 )
I have been using this RAM for a week now, I am not having any problems or anything, but I read some things that sandybridge is supposed to use 1.5v and nothing higher. In my UEFI the RAM is set to 1.65 volts and it is giving it 1.67ish, I am unfamiliar with all the bios settings to get this lower. Is it okay just to manually set the dram voltage to 1.5? I am not overclocking anything yet, just running stock.

That's a good deal for quality Corsair RAM. If you don't have any issues I probably wouldn't mess with it - however lowering the voltage would ensure better adherence to Intel specs. I ran Corsair 1.65V RAM with my 2500K for awhile and had no issues, but I reduced its voltage to 1.55V or so when I was running it. I've since swapped it out.

I dropped it down to 1333 and 1.5, no crashes so far, I guess it will have to do until I get some cash for lower voltage.

You can use memtest 86+ to check if the ram is fine at DDR3-1333 and 1.5V. If you don't find problems, I would just leave it at that and not bother with buying 1.5V DDR3 ram until you want to upgrade to more ram or something. Differences in performance from 1333MHz to 1600MHz is only a few percent.

I've never been able to find a straight answer on the 1.5V vs. 1.65V RAM with Sandy Bridge question. I've seen repeated references to "Intel recommends 1.5V" along with "it doesn't make any difference". I looked over the spec sheet for the chipset, but couldn't find it here, either.

Someone on the forum gave a definitive explanation as to why to keep those voltages within spec... i think it has to do something with the on-die memory controller voltages...

I should of Bookmarked the page - keeping it ~ 1.5v is a safe bet...
