1.25v DDR3 RAM?

[Charlie98]

I was window shopping on Newegg and ran into this:

What is the purpose or benefit to RAM at 1.25v vs 1.5v? Just curious...

lower voltage allows you to populate more dimm slots before stressing the memory controller.

 

[BFG10K]

Slightly less power consumption and heat.

Slightly less power consumption and heat.

very, very slightly. I had some 1.35v RAM I think I measured 1W difference on the Kill-a-Watt vs. the same RAM at 1.5v.

Also, potentially more OC headroom, but that's not a big deal right now for anything other than Llano's using the on-die GPU.

Sounds like a waste of time to me. Ram hardly uses any power fully stressed.

IMO the main benefit of lower voltage rated memory is an indicator or higher quality.
The more voltage a DIMM needs to be slammed with in order to run stable the lower the quality of the chips.

IMO high clock rated, tight timings and low voltage = premium quality modules.

 

[ncalipari]

smaller likelihood of memory failure, compared with another ram module built with the same manufacture process and rated at an higher voltage.



At the same price point a lower voltage module is to be preferred.

This +1

lower power - more important for a laptop than a desktop. small advantage with heat (1W). But then that lower power is part ram and part memory controller/cpu, so not just the ram.

does give a little head room for overclocking as the memory controller can go higher and still be in spec.

otherwise, little needed benifit to have. Only worth worrying about for most people if that is what your cpu needs.
