Getting 8gbs of ddr2 1066 to work?

Has anyone had any success getting 8 gbs of ddr 1066 to work? I want to keep my current speeds, but also add more more memory. I have been told that this is possible, but difficult. Is it truly possible to add 4 more @ 1066 and keep the same timing voltage and speeds? I am trying to find some used ddr2 (becasue of cost), but will buy what ever 1066 RAM you think will work best.

Ram currently in computer (4gb): http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Ram to be added (4gb): http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Current mobo: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Current processor: Phenom II 720be x3 @2.8ghz

Any suggestions? Thanks.

Don't bump. Did you read this statement from Asus? "*Due to AMD CPU limitation, DDR2 1066 is supported by AM2+ / AM3 CPU for one DIMM per channel." Unfortunately the answer is no. Running the RAM at 800MHz will barely make the system slower (1-2%) and you won't notice it unless you run benchmarks. You could try setting the timings to 4-4-4-15 for optimal performance, but it may not work with your processor.

No on answers unless you bump ;) .

Thanks for the advice... If running it at 800 mhz really wont slow me down too much I might just do that.

800MHz is your only option. Besides you're installing an additional 4GB because you need it to speed up some tasks and not only for the sake of having 8GB.

Actually I had an additional 4gb of ram given to me the other day and was wondering if it would be worthwhile to put them in. Thanks.

I know this is an old thread, but for anyone else using DDR2 who comes across this;

I have an old Asrock NF7G-HDready motherboard with an AM2+ socket, just fitted a Phenom 9750 and I have the option to select 1066 for both DIMMS on both channels. I have 2x2GB Geil 1066 in one and 2x2GB Crucial Ballistix 800 in the other. Both clocked to 1116 (558MHZ) running 6-5-5-15 2T timing with no issues, ran many benchmarks, no crashes after 24 hours of use.

This may not be any better performance than DDR-800 with tighter timings (I'll try that tonight), but just to say it worked for me.

Thanks for the reply. Oddly enough I couldn't get the two rams to work together.The computer wouldn't power on at all, when I added the additional 4gb of ram. Any idea why this might be?

Does it work with only the new 4GB kit? What voltage is applied to the modules? 2.1 volts?

I'm not sure, I'm not really an expert at getting RAM to work, mine just did. I set everything to auto, started at the DDR2-800 setting and set 2.0v (then moved to 2.1v for o/c I think). I checked the SPD in CPU-z for 1066 then rebooted into bios and set 1066 with the SPD settings, leaving the rest on auto. This worked fine. (for both the DDR-800 and 1066 DIMMs. They, just to see what they'd do, I increased the CPU clock (is a basic Mobo) and got up to around 1150. I reduced each timing, one by one, until it fell over. Took several hours, but got reasonable results.
