Question 1

is this compatible with the Dell Precision  T5400 computer?

Accepted Answer

From the picture of the mother board I saw, it looks like it would fit.

However, I have that computer, and if we are talking about the same one, it's about 8 years old. Usually memory and motherboards are compatible with each other if they are both from the same decade from my experience.

From this you can not know for certain, however if you can figure out what model the motherboard in that computer is, you could use pcpartpicker (website) to check for compatibility.

I'm not an expert, but I hope that helped.

Question 2

Will this memory work with a Asus b85mg motherboard and i5 4430 CPU?

Accepted Answer

Yes. The mobo supports 1600 DDR3. CPU don't directly affect what RAM you can use.

Question 3

will this work on my XFX MBN790IUL9 LGA 775 NVIDIA nForce 790i Ultra SLI ATX Intel Motherboard?

Accepted Answer

No. Your motherboard can only handbook handle 2gb sticks per slot.

Question 4

Can I buy two of these and stuff them in a motherboard for dual-channel operation?

Accepted Answer

yes you can, but it is highly recommended that you buy a 2 pack of ram if you intended to use dual channel, over buying 2 singles packs and combining them. even though they will work the timings on them could be slightly of making them not run as efficiently.
