Difference 1066 vs 1333

Will I really see a difference with 1066 and 1333?

Dell replaced my 4GB of 1333 with 8GB of 1066 and I am getting tired of going back and forth and them not getting their ish together.

 

No you won't see a speed difference between 1066 and 1333.

Yes you will see a speed difference between 4GB and 8GB. Huge difference.

 

Probably not, it's highly unlikely he'll use all 4 gigs of RAM, with RAM if you can't use it then there isn't any point in having it, your computer will run no faster if it's not being used.

As for speed it depends what you do, if you are writing programs which rely heavily on constantly changing, large size entires into the RAM then you might see a difference but unless you're doing hardcore program running stuff (gaming, number crunching and such) then I doubt you'd notice the difference.

 

You can easily go above 6 to 7GB of RAM these days, I do all the time. It all depends on what your doing with the machine.

 

I am planning to buy 4GB x1 DDR3 1066MHz RAM for DELL XPS 16. I need at least 6 gb DDRam on my XPS.
The problem is, it will work 1333MHz (2gb x 1) with 4GB x1 1066MHz, mixt together?
It will affect the warranty?
Thanks.

 

It will not work at 1333MHz as arrandale cpus only run ram at 1066MHz max, so the 2GB 1333MHz stick you have in at the moment is only running at 1066MHz too. They will be compatable

 

This will not affect the warranty. Generally speaking you can always replace the battery, hard drive, and memory and it won't void your warranty, but the new parts won't be covered under your laptop's warranty unless you bought them from the same company (i.e. memory on a Dell computer).

So what are you going to use that extra memory for? Photoshop? intense video editing?

 

You have got it.
I might change with a guy, he has 8Gb DDRam on XPS. I give him 1x2gb + extra money for 1x4 gb.....I will see if he wants.

 

Get 1333mhz. period. if you can afford extra money for ultimate performance, get 1333mhz with low CL in newegg. its kingston hyper ram but its 4gb kit max... that should prety much destroy performance

 

There's really no point at all if his system won't support the higher speed, just wasted money.

 

i7 chips support 1333 ram, not i5s.

So his system will utilize 1333 RAM (and not downclock it to 1066).

How much performance benefit will you see? It depends, but it's unlikely. Even if you are using your machine to game, create 3D stuff, or program you will not likely notice the difference between 1333 and 1066.

If you paid for 1333, I'd get it but I don't know that you will care all that much once you've got it.

edit: I didn't see a huge benefit going from 4 to 8 gb of RAM on a desktop. (I used 8 GB for quite a while before selling half of it)

 

codred2 only has an i5, so 1066 is beta due to its lower latency
