Ram compatibility question.

[BudgetGamer]

Hello,i am going to buy 4gb single stick for my new build and my motherboard has to dimm slots,so if i buy a single stick 4gb and upgrade it to one more single stick 4gb with exactly the same brand ( corsair vengence in this case) will they work in dual channel?If not,will they at least work as 8gb,will i notice a difference between dual-single channel RAM in gaming?

Thanks in advance.

Two Corsair sticks, even the same brand (Vengeance) and speed etc, may still use different chips underneath it all, since Corsair buys their memory on the open market. That means there is a small extra risk of incompatibility compared to using a matched set. But it's a very small risk. Most of the time it will work just fine.

First of all thanks for your replies,

one more question,it is said that they are clocked to 1333mhz and you need to unlock them through the bios to go up to 1600mhz.
also my motherboard supports 1333mhz and 1600 when oc'ed.Will then my motherboard detect the ram at 1600mhz?


quick edit: http://www.e-shop.gr/asus-m5a78l-m-lx3-p-PER.522983 this is my motherboard will it support the corsair vengence 1600mhz ram?

DDR3 usually defaults to 1333. You just have to set it to its rated speed afterwards.

You should use the same model.

For example if you have CMZ8GX3M2A1600C9, you have to buy that same one to work with Dual Channel.

and putting into right slot is more important. For eg: use color code of that RAM Slot.

The kit doesn't have to be the same model to run in dual channel mode. It may slightly reduce the risk of compatibility issues in general, but compatibility issues certainly don't have to revolve around dual channel mode specifically. Besides, the memory may be completely different even if the model name is the same. Corsair grabs memory chips from different manufacturers as the market fluctuates.
