Mixing RAM Kits

post #1 of 4
Thread Starter 
Hey everyone.

I've got a question that I've never come across before and can't really fins an answer to in brief here.

I've got My current sig rig i7 930 @ 4.0 1.325V 24/7 With this ram:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820145295
In short Corsair dominator 3x2gig kit @1.65V

My system is running 191mhz for the bus speed which move my RAM down to 1524 MHz (762*2) at 8-8-8-20 2T

I'm looking to get more RAM in my system and am torn between another identical set bringing me to 12 gigs or for nearly the same price getting a 12 gig set like this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820145321
and making 18gigs.

So I have two questions:

1. Will my over clock still hold with more RAM at all. I've read it can make or break your OC.

2. Will I suffer more instability because I'm "mixing" a set of RAM. (in short, your opinions on getting two of the same sets and selling my current or just getting what I need now)

Thanks in advance for the help.

You can mix ram but it is a gamble. I would rather buy a matching set and be 100% safe. Adding more ram will always put a greater strain on the memory controller. You will more then likely have to add more voltage to the controller to keep it stable. Thanks

EDIT:I have to ask this. What is the reason you need all this ram for?

1. Mixing RAM isn't bad, it's just "bad" in the sense that you may have to tinker with voltages and timings to get everything stable, especially different kits.

2. As always, you need to remember that adding more ram = more stress on the IMC, and more stress on the IMC = increased difficulty in overclocking.

I do alot or server software dev where applications take a large ammount. SQL servers with that take a toll as well, leaving me around 3 gig free at any time. Some games have hit the limit and I would like to remove swapping as much as possible.

Another 6 gigs would do the trick but When double the density cost near only %50 more, It's appealing.
