Memory for mobo

The mobo [url=http://www.newegg.com/Product/Product.aspx?Item=N82E16813131324][/url] manual said "Due to AMD CPU limitation, DDR2 1066 is supported by AM2+ CPU for one DIMM per channel only"

I got this 4gb [url=http://www.newegg.com/Product/Product.aspx?Item=N82E16820231166][/url], but this brand was not their qualified vendors list would it be okay

Thank you for the reply, I would have been in trouble. G-Skill does not even manufacture any memory for this motherboard chipsets. The MB specs says DDR2 1066, can I install DDR2 800 memory sticks? Please let me know

Thank you

See if this HyerX is compatible with your board. My sticks are on water but with good air flow they should still perform well. I run mine at 1.3v, 1100 MHz slightly OCed. I cranked them up to 1100 MHz after reading an article here at Tom's which they ram stable at 1130. I plan to do some more testing.

That is correct, that's nothing but the kit on the end. If you decide to go with the HyperX don't make the mistake of getting this: KHX8500AD2K2 Notice the "A" added in there, this stuff is garbage.

The only problem you MIGHT have with the G-Skill memory is first boot. It requires 2~2.1 volts. Your system is going to try and boot with it at either 1.8 or 1.9 volts.
Start with only 1 stick, if it boots fine, which it likely will, go into your BIOS and set the voltage to 2.1 volts, shut down, insert second memory stick. If you put them in the right slots, it will run them at 1066 by default, wrong slots, it will run them at 800 by default.
Yes, 2x2gig is the optimal setup even if you do not have a 64 bit OS. You won't be able to use quite all of it, but it is still the best setup to go with for many other reasons.
