samsung low voltage ram

[borisvodofsky]

Question to everyone who has this.

Does anyone know how 1.475 or 1.5v will affect this 30nm ram over time? :\

I'm shooting for 2133

I am considering getting a set, as I got scammed by price pros over in hot deals.

I run mine at 1.475v and I did read that the top limit should be 1.475v or around.

The following is from techpowerup http://www.techpowerup.com/reviews/Samsung/MV-3V4G3/6.html

"I also found that adjusting voltage outside of the pre-programmed voltage mode results in frequency scaling dropping off quite quickly as explained above, so I recommend that users do not exceed the pre-determined voltage ranges in order to prolong the DIMM's life. That means that 1.35V sticks should see no more than 1.475 V, and 1.5 V sticks should see no more than 1.575 V. Both types of DIMMs do seem to scale a little bit once those values have been exceeded, but because the gains are quite minimal, it is not recommended at this time."

So far I've found my Samsung RAM to be very good, easily OC'ed to 1866 @ 1.38v, but I don't think I would try to push it as far as you want to go. If you want 2133, get some 2133MHz RAM.

2305MHz at 1.65V like I told ya 😉

2305MHz at 1.65V like I told ya 😉

When there is a difference in performance I might bother.

Otherwise I don't want 1.65v going through memory that is rated at 1.35v

No need to speculate when Samsung provides the information. Here are exerpts from the data sheets for their 1.35V and 1.50V DDR3 DRAM:


Absolute maximum allowed voltage is 1.975V:

For 1.50V operation, the maximum recommended voltage is 1.575V:


1.35V DRAM:

1.5V DRAM:

good to know :thumbsup:
