Question 1

I have an nForce 790i Ultra SLI motherboard and previously attempted to upgrade my memory (currently have 4 1GB DDR3 sticks) and purchased incompatible memory. Will 4 of these (for a total of 8 GB) work in this motherboard?

Accepted Answer

I looked up what I believe is your motherboard (EVGA Ultra nforce 790i Ultra), and the manual document says that your system supports maximum 1GB memory modules across 4 slots (4GB maximum), so you may actually already be at the maximum possible memory configuration already.

-HOWEVER-, normally older systems around your computer's era usually prefer 1.65v ddr3. This new ram here is 1.5v ddr3 designed for newer systems from 2012 and up.

I would suggest you go filter newegg and look for 1.65v voltage ddr3, and try that instead.

Question 2

Why are you recommending this part when it is the wrong one that I need?

Accepted Answer

I'm confused by this question. Who recommended and how do you know it's the wrong one? Does your motherboard not support DDR3 memory, or is it the speed you're worried about? If it's the speed, it will clock down to the maximum your motherboard can handle. RAM is pretty interchangeable.

Question 3

Will it be compatible with Lenovo ThinkCentre M58P 7484 which uses the DDR3 1066MHz (PC3-8500) memory? Thought it should be but I bought and installed it does not work. Could it be a bad chip?

Accepted Answer

I have looked it up and verified this ram is supposed to be compatible with your system. However you can not mix this ram and your existing DDR3-1066 ram. If you wish to use this ram you would -HAVE- to remove all of your existing ram and install only this ram.

And as to how much of it, I have found confirmation on the Crucial ram website for your system model that the maximum supported ram is 16 GB (4 x 4GB). I know this is not crucial ram here, but that is the maximum your system can support (OF any kind of ddr3 ram).

Question 4

Will two of these work in a dual channel configuration?

Accepted Answer

Yes
