Default Can Gigabyte ep35c-ds3r v2.1 support DDR3 1600 RAM?

I'm intending to upgrade this old computer of mine a little, since its
Intel Core 2 Quad Q6600 @ 2.40Ghz is still modestly fast. Its 2GB
RAM A-DATA DDR2 800 I bought 3 years ago seems to be low to me.
Sometimes the virtual memory go up more than 2GB on Task Manager and
the system slows down greatly.

This motherboard has its Qualified Memory Vendors List (QVL):
http://download.gigabyte.us/FileList...c-ds3r_2.1.pdf

Although the board supports DDR3 1333, there is no 2GB RAM stick on
this list. It has two 2GB choices for DD3 1066: 2GB Kingston
KVR1066D3N7/2G or 2GB Kynix HYMT125U64ZNF8-G7. Either choice would
boost my systems' current 2 GB DDR2 800 to 4GB DD3 1066. And I found
2 sticks of 2GB Kingston KVR1066D3N7/2G is $40 at newegg.com. Would
this be a good upgrade for my system?

Forgot to say, if you can comment on my title question, I'll consider
DDR3 1600 too. Thanks.

To use 3 channel ram it will need 3 sticks. Or 6.
You can try three 2 gig sticks of 1333 and see what happens.
You can always over clock the 1066 but it will need a good fan.
In any case, it won't be able to use more than 3.8 gigs anyways
unless it is running 64 bit.

Part of the information I provide, may seem superfluous to you, but
I include it to make absolutely sure you know about it.

Motherboards like this, support only *one* kind of memory at a time.
The shared bus can only run at one (proper) voltage at a time,
which is why the memory types must be segregated.

http://images10.newegg.com/NeweggIma...128-082-05.jpg

You cannot mix DDR2 and DDR3 DIMMs at the same time.

You either install DDR2 DIMMs (up to four of them).

Or, you remove them, and install two DDR3 DIMMs instead.

The Newegg advert says...

GA-EP35C-DS3R
http://www.newegg.com/Product/Produc...82E16813128082

Memory Standard DDR3 1333 / DDR2 1066

In the picture, there are four DDR2 slots. And there are two DDR3 slots.

So the max DDR3 config, is going to be two sticks only.

*******

Crucial lists a DDR3-1333 2x2GB kit. $43.99 USD.

http://www.crucial.com/store/listpar...202.1)&Cat=RAM

This is what the Intel datasheet for the P35 chip lists. The second statement
is telling you, that operating the P35 on the Gigabyte motherboard
at DDR3-1333, is an overclock of the Northbridge. (Some Northbridges,
they're given a voltage boost, to help them run that fast.) Since
Gigabyte has done some testing, they know how difficult it is to
make that chipset run at 1333.

DDR2-800/667 frequencies

DDR3-1066/800 frequencies (82G33 GMCH and 82P35 MCH only)

Supports 1-Gb... DDR2 or DDR3 technologies for x8 ...

The latter statement, could use a 128Mx8 memory chip, as that
is a 1 Gigabit chip. Using sixteen of them is 2GB. That means
a 2GB DIMM is the largest DIMM supported.

So, you can buy the Crucial 2x2GB kit, and install only those
two DIMMs, for a total of 4GB at DDR3-1333 CAS9.

You also have the option, of shopping around for some
2x2GB DDR3-1333 kit, with a lower CAS than CAS9.

You are correct. I did not look closely enough at the
ram slot locater things.

I was looking at the P35 part, and thinking it isn't designed like
a Core i7 LGA1366. That's why I went looking for a picture,
just to be sure.

A pair of DDR3-1600 sticks would fit in the motherboard, but
I don't know if there is an overclocking setting that will
give that high an effective clock rate. But a high speed
memory DIMM can run at a lower speed without a problem. So
that stick could run 1333 or 1066, with some changes in
CAS and the like, possible.

As to whether a 4GB config is good, it would work best with
a 64 bit OS. When you use a 32 bit OS, with the Microsoft
memory licensing limit, you only get to see something like
3.1GB free or so. Due to the memory map setup. So a 4GB
config is not "twice as good" as a 2GB config. There are
some losses along the way.

But with the pricing, it's a pretty cheap upgrade.
