So I am looking for new ram and i see the have different volts
so what I think Ill buy is this:
OCZ OCZ2G10664GK 4GB 1066MHz PC2-8500 Gold Edition Dual Channel DDR2 Kit
and it says that its 2.1 Volts/240 Pin DIMM

will this volts work with my Msi 770T-C45 Mobo or wont it matter at all?
do I need to change something to make it work?

For any ram you are considering, do your own homework.
Go to the ram vendor's web site, and access their configurator.
Corsair, Kingston, Patriot, OCZ and others have them.
Their compatibility list is more current than the motherboard vendor's QVL lists which rarely get updated.
Enter your mobo or PC, and get a list of compatible ram sticks.

Here are a few links:

Cpu performance is not very sensitive to ram speeds.
If you look at real application and game benchmarks(vs. synthetic tests),
you will see negligible difference in performance between the slowest DDR2 and the fastest DDR3 ram.
Perhaps 1-2%. Not worth it to me.
Don't pay extra for faster ram or better timings unless you are a maximum overclocker.

1. I cant find compatibility list pm the OCZ site or the Msi site
2. I saw lots of other rams have 1.5 volt so I am asking is there something you need to adjust to use 2.1 volt ram

2.1 ram is usually 1.8v ram that is capable of being ocerclocked to higher speeds.using 2.1v

In the bios of many motherboards, there is a setting to increase the ram voltage. If you already have the ram, try it without changes. Test with memtest86+, you should get NO errors on at least one full pass. If you get an error, increase the voltage up to 2.1v.

The standard voltage for DDR3 is 1.5V; don't worry about that. The standard voltage for DDR2, which is what you have, is 1.8V. But it's pretty common to see "performance" RAM that uses slightly more voltage than stock settings. You will have to go into the BIOS and bump up the voltage to 2.1V if it is not stable ... but they usually make that one of the more obvious settings and it should take you about 2 minutes to do.

If you don't want to mess with any of this, you might as well just get some DDR2 that's 1.8V by default. It should be easy to find some that performs roughly the same as the set you have your eye on.

If I am not mistaken, your motherboard requires DDR3 ram; The ram you mentioned-- DDR2 will not work. DDR3 ram standard voltage is 1.5v. Overclocked maximum is 1.65v. Anything higher than that may permanently harm a i3/i5/i7 cpu. What it will do to a AMD cpu, I don't know.

I think you are mistaken. If this is the motherboard, it's definitely DDR2:

Also, the 1.65V limit for DDR3 only applies to i-series CPUs. I have a system with a Q9550 and four sticks of Patriot DDR3 with a recommended stock setting of 1.7V, and had to set them to 1.8V to get them stable since I was using all four slots. No ill effects from that. I assume the same is true for AMD quad cores, since I haven't heard anything different.

At any rate, if it applied to more than just that one set of Intel "i" CPUs, you probably wouldn't find all that DDR3 on the market with default voltages of 1.7 and up. But they do make tons of it, so it's not a universal problem.

That is definitely a DDR2 motherboard. I googled Msi 770T-C45 and I got this hit which is a ddr3 mobo.

What gives?

I suggest the OP run CPU-Z and see what kind of ram and motherboard he already has installed.

According to MSI's site, that exact same board is DDR2:

http://www.msi.com/index.php?func=prodmbspec&maincat_no...

Either the site you found has bum information ... or maybe you got tripped up because it says the board "supports" AM3 processors -- which can mean either a true AM3/DDR3 setup, or an AM2+/DDR2 setup that's technically compatible with AM3 but not specifically designed for it. I think this board falls into the latter category.

the difference is that the 770T is ddr2 and 770 (with out the T) is ddr3
