Mixing Corsair 1066MHz & 800MHz RAM

Sup ppl?

I have the ASUS Striker Extreme MoBo (the first one) and currently, I have 2 x 1GB Corsair Dominator RAM @ 1066 (http://www.newegg.com/Product/Product.aspx?Item=N82E16820145043), running at the max 800 MHz that the MoBo "officially" supports. Now, 2GB isn't enough, so I wanna go up to at least 4GB.

 

From all the reading i've done, it appears that getting 2 more sticks of my current Memory to sum up to 4GB may not be the best option, since having more than 2 Memory Modules can interfere with OC'ing, and the 1066MHz Dominators are SO exepnsive right now, i've decided to go with the 2 x 2GB Corsair DDR2 800MHz (http://www.newegg.com/Product/Product.aspx?Item=N82E16820145241). Now, since my MoBo can support 8GB of RAM in all, I was wondering if I could just run 6GB with all 4 sticks of RAM. So, (finally) here is my question:

 

Will my nForce 680i ASUS Striker Extreme MoBo work okay if I put the 2 x 2GB 800MHz in Channel A, and the 2 x 1GB 1066MHz Module in Channel B? I'm thinking that should be a good setup for 6GB with each pair running in Dual Channel. Also, i'd run the 1066MHz at 800MHz all with 5-5-5-18-2T so it can work at 1.8v with the specs for the 800MHz Modules.

 

I know this isn't a situation that would have a simple, definitive answer, especially they are two different sets of RAM with different specs and versions will be different and so on... but i'm interested to hear the feedback from you guys on this setup.

 

Nuff Respect

you have less than a 50% chance of success.

mixing ram is not supported or suggested.

see the 2 links below.

 

actually that board takes up to 16G but a 2x2 kit is the most Corsair has certified for that board. http://www2.corsair.com/configurator/product_results.aspx?id=15763

i have the same board and its hard enough getting certified ram to work by itself on it much less 2 kits.

Wow, you certainly are the advocate against mixing memory, aren't you? Well the two links in your sig were some good reading and I have a much better understanding when it comes to RAM on a whole. But since there is still some percentage of my setup working, I suppose it can't hurt to try, right? I probably could up the NB voltage, loosen timings and lower frequency. That's assuming there's no way to cause any permanent damage.

There's a bit of confusion with this MoBo when it comes to max Memory it supports; first it was suppose to be 32GB, then later corrected to be 16GB (such as on the Corsair Config thing which i've been on a long time ago) then, even on the official site, it shows 8GB max (http://www.asus.com/Motherboards/Intel_Socket_775/Striker_Extreme/#specifications) but regardless, I doubt i'd ever need to go over 8GB, at least with this machine

The NVidia i680 chipset cannot use memory made with memory IC's larger than 128M x 8 density, and most of not all of our current DDR3 production will use 512m X 8 Memory IC's which would not be compatible with that MB.
