1.5v vs 1.35v laptop memory


Recommended Posts

My laptop came with a 4gb 1.35v ram and I want to upgrade to 2x8gb ram. However, I find that 1.5v tend to be cheaper than 1.35v. Why is that? Any real world difference in performance?

There's not going to be a performance difference. Spec's are specs in that regard. You need to make sure your laptop is compatible with whatever voltage you get though.

Well, i think both, as I have 2 in, one 1.5v and the other 1.35v.

 

So I guess I could go with the cheapest 1.5v.

That probably means they're both running at 1.5v.

i agree - theyre probably both running at 1.5v.

 

i'd just go w/ the cheaper stuff if youre upgrading. ive never seen benchmarks, but i'd be very curious about what impact on battery life the 2 specs would have.

It's going to be 1-2W difference @ load and <1W @ non-load per dimm. So how much of a difference it makes would depend on the laptop. For example, mine has a 16W TDP and uses 11-13W typically. So you could get a difference in power consumption of ~7-30% (because even a single Watt is considerable difference).
