RAM Upgrade From 6GB to 12GB Need Help Please

by basicair1 / March 25, 2009 10:42 AM PDT

I just bought a brand new Gateway FX6800-11 from Newegg and it just shipped. Here's it's details for those who aren't familiar:

http://www.newegg.com/Product/Product.aspx?Item=N82E16883113092

Basically it's an Intel Core i7 machine with a good video card, hdd, etc.

It has 6 memory slots and it comes standard with 6GB of 1066 DDR3 tri-channel RAM. This RAM comes in the machine as 3 sticks of 2GB each.

So there's 3 open slots.

If I go with faster RAM for the other 6GB in the other 3 slots, will it only run at the slower speed of the current 3 sticks?

The reason I ask is I have heard that it may, and if it does, then I might as well just get 12GB of faster RAM and replace the current 3 sticks of slower RAM as well, right?

But then again, I have heard on various forums that these new motherboards for the i7 either aren't supporting faster RAM speeds by design or by the current BIOS versions given out in the new i7 machines by companies like Gateway and Dell.

So there's my dilemma.

FWIW, I am not a fan of Gateway really but I had a similar i7 machine on order from Dell for weeks in the new 435T Studio XPS they just came out with and it was about $500 more and kept having delays so I cancelled that order and got the Gateway from NewEgg and it just shipped earlier today.

Any help with this RAM issue would be much appreciated.

I posted this in the "Desktops" forum which I now realize was a mistake as this is the proper forum for that.

I agree that in 99.99% of the machines the entire memory system runs at the slowest of any of the following items.

1. The slowest stick of RAM.
2. The speed of the memory channel in the computer.

It's been a shame to see the speed freak lose their money over paying extra for higher speed memory and the machine they pop it into doesn't take advantage of the higher speed RAM. You should tread slowly here.

-> My closing comment is that for now, for today 2 to 4GB is the sweet spot. There are very few that will gain speed past that.

Go to the link in my original post if you don't know simple things like what OS it is. It takes 2 seconds to click the link and find that information. I am not trying to be rude, but come on now- That's why I gave the link to the system in the first place.

It's Vista Home Premium 64 bit.

Not to sound rude

But many won't use the supplied OS. We can't guess so we'll ask.

If asking questions is unacceptable, please state so and you won't be asked.

1066?
by chickenorfish / March 26, 2009 4:05 AM PDT

if it shipped with 6GB of 1066 DDR3 i assume that the motherboard has 1066 ddr3 ram slots. if this is the case, you cant upgrade to faster ram. you can stick in there, but it will only be recognized as 1066 ddr3 ram. tho you could get higher quality ram, like corsair or something

Will more RAM speed up my system?
by GR-TEK / March 28, 2009 6:52 AM PDT

You shouldn't mix RAM of different speeds. The Motherboard will slow down the faster RAM to the same speed as the slower RAM. RAM that does not match could also cause the system to freeze.
Just because RAM is 1333Mhz and not 1066Mhz does not mean it is faster, check the Latency timings of the RAM. For example; 800Mhz DDR2 RAM with latency timings of 4-4-4-12 is the same speed as 1066Mhz DDR2 RAM at 5-5-5-15.
You will find that most 1333mhz RAM is either 9-9-9-24 or 7-7-7-21.

If you are after better performance with more RAM then you should check the link below first...
