Single or dual ram for a working laptop?

Hello what is best for a PC to work that is only designed for home office Singel or Dual ram or it does not matter

In this case, even single channels would be enough… Because you can see no difference in pure office work.

Well if 40% slower means no difference. Really interesting view.

40%? I'll take it back… But do you notice it so strongly when the program starts?

If you run the ram in the dual channel, the memory is approx. 40% faster. You can see that in most of the work. After all, 40% are not a cardboard handle.

Of course you notice a difference. As I said, it's 40%. If not more.

A single customer used permanent singlechannel because of a defective slot, and yes, when I think about it: the PC is relatively lame despite the SSD…

40% from where did you get that knowledge, in reality you have up to 10% in the best case. Or do you mean benchmarks that only measure theoretical values.

Never 40%, in reality that is a maximum of 10%. Where did you get this strange statement, yes I know because the bus will be doubled, then would be even 200% faster after sales. But that's not the case, with no test except with a synthetic (i.e. Theoretical) test you get something that is over 10%, usually even less so than 5%.

Single is enough, the latency of the memory is much more important

With dual, you can at best achieve 10% in real life, but usually 5%.

Just like you don't achieve very much with quad. And not four times.

the conclusion says it all.

especially at office you don't notice anything.

Ashes on my head. Of course you are right. It was like today that I had a customer with whom I discussed SLI. And then you know that the additional power is about 40%. And I think somehow the 40% burned into my brain.

But as I said you are right. Sometimes it is only 2-3% with the working memory. I even saw a test of a game and the system showed 5 fps more with just one bar. It is very questionable whether this is due to the storage.

It is not 40%. But someone has a lot of idea.

Is about how much memory you want to install so the capacity. If it's over 4GB it's dual channel if your mainboard has more than 4 slots. You have to keep in mind that if your mainboard only has 2 slots for the ram and you install 8gb ram, for example, install 2x4 gb stick and you want to upgrade it in the future, let's say to 16 GB ram, then you have to then remove both RAM and buy 2 new 8GB sticks. With the single channel you simply buy an 8GB ram stick and you're done.
