RAM for i5 750

Hello

Can someone help, I want to upgrade my ram from 4gb to 8gb using 2 x 4gb. My current ram works at 1.5v and 1333mhz. I was going to get some corsair dominator 1600mhz at 1.65v but looking at the intel home page it recommends only using ram with 1333 or 1066 and 1.5v or below.
I did look at corsair's range of 1333mhz but still have a 1.6v.

So can I use this ram with the cpu? I know my motherboard can support it.


My system is:

Hi bob70932

CPU voltage is independent from RAM voltage. I'm not sure I am understanding the question correctly. If you know for a fact that your motherboard will support the RAM then you will not have any issues.

There are no compatibility issues between RAM and CPU. It all depends on whether your motherboard will support the components in question. This is why the motherboard is considered to be the backbone of the computer.

The i5/i7 processors are compatible with RAM that operates at either 1.65v or below. So your Corsair sticks should be fine if they operate at 1.6v.

Ross if my post above is incorrect, I need to know why so I'm not making the same mistake again. Please elaborate on your comment.

Why do you think there would be an issue between CPU and RAM voltage?

This does not make any since to me.
Why would a board designed for i5/i7 support a memory architect which has a voltage level that is to high?
Would this be a limitation of the board design not the CPU?

Hi

I have attached the ram I am looking at. Being new to the computer game I hear it's best the get ram with 1600 mhz but to run it a a lower rate ie 1333mhz. Is this right?

This is a limitation set by Intel themselves.. See screenshot which was taken from this FAQ found here:

http://www.intel.com/support/process.../CS-029913.htm

I guess if you over-clock in the future you will have some headroom but it won't harm the RAM any to under clock it.

OK after reading through the link, I would ask this. If an i5/i7 motherboard supports memory that will damage the CPU, why would the market allow the sales of such a board? I'm still looking at the support list for the motherboard. If the manufacturer states it will work, I have no problem with it.

I did check some of the RAM on the qualified vendors list and it would seem most run around 1.6-1.65v so no problems there..

The actual list can be downloaded here:

Ok let me get this right, intel say only use memory at 1.5volt + or - 5%, which if we + is 1.57v. So the ram from corsair which they say is for i5, intell say it is not because it runs at 1.65v?
And if I am not going to overclock my pc I should just stay with 1333mhz as the system will default to this anyway even if I have 1600 mhz ram.

Ross thank for finding the support list, however it does seem a little out of date, could not find any 8gb sets on there.

Has anyone heard of this ram?
