Hi Guys,

I would like to upgrade my memory with an additional 4 gb.

Motherboard: Gigabyte MA770t-ud3p
memory: 4gb 1333mhz ddr3 ram geil value kit spd:9 (2x2gb)
I would like to add an additional 4 gb (2x2gb) for quad channel support (will it support that?)

If I get 1600 MHZ, will it be clocked at 1333?

Also, I am not sure what kind of memory would work with the above type, I bought it almost 5 years ago, and I cannot find the exact same type for sale anywhere.

Could you please help me with choosing the proper type of memory for the one I already have?

Thanks a lot in advance! :)

^Right. Its a crap shoot if you can't find the exact same memory. Ram/motherboards can be finicky. You may be better off purchasing some 2*4GB and then selling what you have.

It is a dual channel board, quad is not an opton.

You can add 2 more sticks but without the exact same kind of memory, it may or may not work in dual channel.

Dual channel requires matched sets of 2 or 4 to work.

In addition unless you are a gambler, you have to pick memory from Gigabytes tested compatible list.

It is possible to run RAM that isn't matched, but it will revert to single channel in most cases.

If you want to be sure of you install, your have to get a whole set of new RAM.

Even if you are able to get the exact same RAM there is still the chance it won't run in dual, because it isn't a matched set.
Single channel will loose about 10% performance.

Thank you for the reply.

If I want to keep my old memory and willing to go with single channel, will it work correctly if I pick up modules that are listed as compatible by Gigabyte? And if I understand correctly the memory would need the same specs.

Unless it has been tested no one can say for sure.

It is possible ie 1333 and 1600 to work together, but it will operate @ 1333, unless you overclock it.
The better you match it, the better your chances.

I have on a few computers had unmatched RAM, run in dual, but it is the exception.

If you are really short on memory now, even single channel will be faster.
When you are short of RAM, the computer uses the hard drive for memory, and hard drives are dead slow.

OP, which revision is your motherboard?

GIGABYTE - Motherboard - Socket AM3+ - GA-MA770T-UD3P (rev. 3.1)
http://www.gigabyte.com/products/product-page.aspx?pid=3805#ov

If you're using an AM3 CPU then you may as well stay with 1333MHz RAM:

VERY IMPORTANT INFORMATION REGARDING AMD AM3 CPU's and RAM SPEEDS
http://forum.giga-byte.co.uk/index.php/topic,2515.0.html

Since your motherboard doesn't have a heatsink on its VRM, this is worth reading:

The following RAM is now discontinued but it may still be available at a computer shop:
