Adding a Different Ram Stick To 3 Existing Ones

post #1 of 5
Thread Starter 
Hello!
I have this kit: Kingston KHX1600C9D3K3/6GX. 3x2 1600MHz DDR3. Since some of the newer games started almost maxing this I would like to add another 2 GB. I've looked at my local market and at ebay but couldn't find the same stick. So the question is, can I add a different, cheap stick to the existing ones (same clocks and 2GB), and will it run without problems in dual channel?

Hi there tongue.gif

well IMHO, you can add another 2gb stick with the same clock and specs and call it a day. if what you want is the extra 2gb. tongue.gif

Now regarding dual channel, Dual Channel provides a performance increase, and the truth is that your kit is a 3x2 which means is a Triple channel kit, so adding another stick would not convert it into a dual- dual channel.

Dual-Triple-Quad Channels ram sticks, as far as I know are just ram sticks tested together with the same specs, and are veryfied by the manufacturer. and they claim that the ram stick packed in the dual-Triple-Quad channels will work perfectly with one another.

You can buy 2 of the same ram stick separately, and use it, but still it wouldn't be a dual channel kit, because it's not warranted by the manufacturer that they will work together, and in case they don't work well together, it's not their fault.

I hope that helps rolleyes.gif

Maybe I didn't understand your meaning correctly, but dual channel is not regarding the kit, but how the cpu works with the provided memory. So my question stands: as long as the speed and timings are the same, will the added stick work as dual channel with the other, meaning 2+2/2+2?

It's actually a matter of both things,

1st your CPU and your motherboard must be able to support that feature, then your ram must be able to support it, if all those things match then you have yourself dual channel support rolleyes.gif

Regarding your problem, the thing is that even if you use 1 more ram stick with the same specs and speed, it does not guarantee you to have support for dual channel, because the manufacturer did not tested and approved those 2 pair of RAM sticks together working in dual channel mode.

Right now you have a triple channel kit, which means that those 3 ram sticks are tested to work together in triple channel mode by the manufacturer, if you change 1 of them to another ram with the same specs, then that doesn't guarantee you to have a triple channel kit, does that makes sense?

And if you take one stick out of the 3 then you have a dual channel kit, because 2 of those 3 sticks were tested and approved to work together.

You can still try to use another stick with the same specs, and who knows maybe you are in luck and you get yourself a double dual channel ram tongue.gif

but you can still add a ram stick close to the same specs and have the extra memory.

Thank mate!
Decided to pay twice more for a new 2x4 Corsair Vengeance ( CMZ8GX3M2A1600C9) and try to win back some money selling my set on Ebay. I've come to understand that even if I were to buy a new 2x2 kit (for 25$) there's still a small chance of something going wrong, and then the hassle of international shipping returns etc...
