Adding memory

post #1 of 4
Thread Starter 
So I was going to buy a new 16gb Kit of DDR3 and sell my 8gb kit but lets just say I've turned sour on what I was going to buy and may have to replace a few components in my system at the same time.

Anyhow, I was wondering, how reasonable is it to pick up another 8gb kit and populate all 4 slots? how much will it hurt my performance and is there any decent way on going about getting somewhat compatible ram? I've had the sticks I've got now for quite some time.

The problem with adding another 8 gigs is finding compatible memory.

Background.
Memory manufacturers buy memory ICs (the black rectangles on memory sticks) from various manufacturers. They buy a bunch of ICs and build a batch of memory sticks and sell them. When they want to make more memory the buy more ICs from whoever has the lowest price at that time. The problem is that even though the new memory may have the exact same specs, it may or may not be compatible with the previous batch. Sometimes it is, sometimes it isn't.. So, even buying the exact same memory with the exact same specs from the exact same manufacturer is no guarantee they will be compatible Note that manufacturers only spec 4 or 5 timing parameters. There are actually over 20 of them and that's where the incompatibility comes from.

Corsair (and some others) actually add a revision number (Rev #) to the part number to indicate an IC change to help their customers purchase "matching" memory sticks. Corsair) will actually lists which ICs are used with different Part numbers.

2x8gb is at a good price right now.
You can easily sell your 2x4gb or keep it as backup. Which is what I prefer.

You could use the exact same model as yours, but they could be slightly different. As bill mention, the IC could have changed or PCB.
