I'm working on a new build (relevant specs below) and I'm wondering if I can use G.Skill Trident X 2400 CL10 1.65V and underclock the memory to run at 1866 1.5V with tighter timings (or even 2133)? What do you guys think - I just want to know if this is a practical idea.

I'm aware that RAM voltages and how it affects the CPU MC and its life is a really fuzzy topic. So I'm planning to run 1.5v for a while before I feel like bumping it up. I'm not planning on CPU OC yet, maybe slight increases in the future.

CPU: i5-4670k
MOBO: Asus ROG Hero

As far as price is concerned, the Trident X's are about $5 more than the current market price for G.skill 2133 CL11 snipers or 1866 CL9s - so cost savings by buying 1866/2133 1.5v aren't significant.

This would be my 3rd build and the first that I would take to OC in the future if my experience if relevant.

that memory has a SPD voltage of 1.5 @ 1600Mhz. so you will be able to underclock it and run it at 1600 at least. anything above 1600 is a overclock freq and may require addational voltage the 1.65v that you see is the ddesigned voltage requirement for 2400Mhz. you may be able to get it to run at 2400 at 1.5v but that is not a guarentee. 1866 and 2133 may be possable at 1.5v. your best bet would be to get high freq memory rated at 1.5V

Should be able to run 1866/8 or 9 at 1.5, 1.55 tops, but.......with your CPU and mobo, I'd just go ahead and run 2400, it's perfectly safe, may need a slight CPU OC for 2400, but is prob just changing the multiplier to 40, great mobo and CPU, you shouldn't have any problems, if so give me a shout

Thanks Tradesman. I'll go ahead with the TridentXs and see how far I can get with 1.5/1.55v before I decide to jump into 2400. I've never touched cpu OC before, so I'll definitely contact you if all hell breaks loose (i.e. i screwed up).

Navalofficer, I understand where you're coming from... but for $5 more, I might as well just get the Tridents, a higher quality IC, than get 1866/2133 rated for 1.5v for pretty much the same money.

I'll check back after I have everything put together.

any update to this? I have the trident-x and a rog maximus gene VII on order + a 4790k so I'd like to know what I'll be aiming for when installing the trident-x

With your combo can run the full 2400, may take a small OC of the CPU

would it not damage the cpu at 1.65v?

No, Intel even certifies 1.65 sets, it's been perfectly safe for a long timeback to the initial Sandy Bridge CPUs and before

Just posted the below in a similar thread - (I don't know if all mobos support this or not):

FWIW - I use Trident 2400 with i7 4770k and Gigabyte ga-z87x-udh4 - I set XMP to Profile 2 and clock to 24 (on Memory setting tab voltage shows as 1.65v greyed out) However, on the DRAM voltage tab I set it to 1.58v. I always run stress testing that includes RAM and never get any failures. Mobo monitor reports memory running at 2400 MHz. HWInfo or Aida64 reports DRAM voltage as 1.57 or 1.572. I don't know if this is unusual or not - but it's within the 1.5v +/- 5% Intel recommendation while fully utilizing the RAM bandwidth....

The DRAM Voltage is not significant. All DDR3 aftermarket systems can support 1.65V. Intel recommends 1.50V because they do not support above standard RAM, but we have tested it to work great.
