1.5V on the memories?

[tigre_est]

Hello, I have read in some reviews that the RAM memories to be mounted with i7 2600 is much better to be 1.5V instead of 1.65 and I would like to know why this is the case, that is, why the voltage of 1.5 Volts is better.

On the other hand, I also see that there are memories of 1.35V and they are more expensive. Why are they better at lower voltage?

Greetings.

The answer is that the memory controller inside the processor (intel i7) does not support more than 1.5V, unless you don't mind damaging it.

The existence of memories that work at lower voltage, on the one hand, means an improvement in consumption, and on the other, an advantage if they are used to do OverClock, as it is possible to increase the voltage to force higher working speeds.

Salu2!

PD: Try not to open a post for every doubt, and don't question all the answers, because there are things that are objectively clear and overcome these, we enter into the tastes of each one, that not being an "expert" means not being a maniac.

I opened this topic because it seemed to me to be a very specific question. In any case, I understand what you are telling me and I really appreciate the answer because it is clear and concise, which allows me to learn a lot. What I am trying to do is to understand things so that I am not carried away by feelings.

Going back to the voltage issue, is that why Gskill Ripjaws are recommended over Kingston HyperX Blue for the i7? (leaving aside the latencies)

I say this because it says:

-in the Ripjaws... 1.5V
-in the Blu... 1.5V (1.425V ~ 1.575V)

Perhaps I am not reading it correctly, and that operating range of 1.42 to 1.57 is better than just 1.5V
How do you see it?

Regards and thanks again.

No, let's see, the voltage for a RAM to work is varied and depends on the type and manufacturing etc. These DDR3s are initially manufactured for 1.5V as standard, although there are some that need more voltage to work and others less, it's like saying that a car with 90HP consumes 6l/100 and there are some that consume more and others less, it doesn't matter much and they work exactly the same.

It's simply evident that the ones with lower voltage are supposedly better because they consume less and therefore also heat up less. This is already an aspect to look at when doing overclocking, but when you want to make a memory work faster than the specifications, you normally have to increase the voltage, so if you buy some with a high voltage already from the factory, it could be a limitation. In addition to speed, what influences performance in memories are the latencies, the higher the speed, the lower the latencies and the lower the voltage, the better the characteristics the memories have.

"(1.425V ~ 1.575V)" This simply indicates that they tolerate a variation in voltage following the standards.

That voltage range is the amount of more or less that the memory can withstand to function smoothly and without damage, for example for overclocking, since the Kingston HyperX Blu are often used for OC.

The Ripjaws I don't know the range they support, it's not indicated on the page, but it's not fixed at 1.5V because they are also often used for OC and I have evidence that something can be touched in terms of voltage.

Anyway, if you don't plan to do OC, that's not for you, you're interested in fast memory with a lot of capacity for the work you will do, nothing more.

Ok I understand perfectly everything you tell me. I am learning a lot, thank you very much.
So speaking of the CL9 1600, would you stay with Gskill for the very slight improvement in latency or is it indifferent?

It's that I have heard that Gskill fails more than HyperX.

Thanks and regards.

I would stick with G.Skill, so far I only have good references of them, and having a lifetime warranty as well, the truth is that I don't worry that they will fail.

Well, better if they don't fail, especially in a team that is for work, that's why I ask; if for example you told me that the Kingston fail less even being a little slower, I would not hesitate to put them. But if you tell me that the Gskill don't fail, I believe you and I put them

It's not that they fail, aver, in fact up to this day I have not seen any memory module fail, and quite a few have passed through my hands over the years... I have come across some module that didn't work but I say come across, that has come into my hands, but of all the memories I have bought and installed in my computers none have ever failed.
Memories usually fail very little, the world index must be very low :risitas: that's why they normally give a lifetime warranty.

The life of a memory is in danger either when extreme OC is done or when they are next to some defective/damaged component (ruined motherboard, damaged or poor quality power supply...) but just like the memories that is also suffered by other components, it is logical.

Here in general we usually recommend G.Skill because of what we have seen from them and the quality, although that does not rule out other brands and models, Corsair are also good and fast, despite the problem of high heatsinks.

OK. Thanks Sylver.
