Memory Compatibility issue! Some solutions?

[zicmaveric]

Hi all!

 

This is my first custom build and it is for video editing. This is the list I ended up purchasing (thanks to help from a good number of you):

Now, everything is arriving tomorrow or Monday and I'm psyched for the build, but I've realized I've made an error. I bought RAM that runs at 1.65V whereas my CPU 4970K only allows up to 1.5V

 

Some solutions to this it seems are underclocking (or UNDERVOLTING) the RAM and tweaking it until I get a stable performance at the 1.5V mark. Now, I've read from some forums that underclocking the RAM would allow me to yield some better latency figures from the hardware. Is that true? Also, is it true that it improves lifespan? Is this a good solution to my issue? Does running the RAM at 1.5V put too much strain on the CPU of which the max is 1.5V? Is underclocking at 1.35V dangerously low for the RAM? How does it really work? I'm getting some mixed info (and not much of it) online. Please help clear this up for me.

 

My other solution was to return the RAM (Corsair Vengeance) to purchase some Mushkin Blackline (either at 1.35V or 1.5V). This will be more expensive in the end because I have to pay shipping costs to return the item and then purchase a new item (even though the Mushkin is cheaper)... What are your thoughts on this other solution? Here are the Mushkin models I was looking at:

So what do you guys think? Can anyone help me with underclocking? Is that even a viable option? What other options are out there?

 

Thanks!

I just noticed that I'm running on Haswell with 1.65V RAM.

 

It just works.

Is this your RAM?

Maybe it works because your system automatically underclocks the RAM to fit the CPU's maximum. If the RAM is running full 1.65V doesn't that wear down the CPU at a faster rate?

The Ram will work fine don't worry about it.

Do you mean it'll be fine when undervolted? Or do you mean it'll work fine "plug and play"? Because running it at 1.65V is certainly not good for the CPU... no?

IT definitely wont damage anything but it might cause slower speeds

It will work fine at the rated voltage of 1.65V.
