I know 4 sticks of RAM is hard on your northbridge...

I have 2 x 1 GB of A-DATA DDR2-800 RAM at 4-4-4-12.
I just picked up a single 2GB stick from Fry's.
It's patriot and it has the same speed and timings, just different voltage.
I intend to run them at 1:1 anyway so that doesnt matter.
But do you think this would hurt my overclock?
(266 x 11 @ 1.325V)
Finally, should I add a bit more northbridge voltage?
 
In my testing (at least on my previous DFI P35), 3 dimms is basically in between the stressfulness of 2 & 4.

I'd try w/o increasing voltage, & then do so only if necessary.

Of bigger importance would likely be tRFC (for the 2 GB dimm), but if you're running lower speeds like < DDR2-850ish, it won't likely even matter...

You're really underclocking that all to DDR2-533 though? 😕

You should be able to do 2:3 (DDR2-800) at least without any trouble or extra voltage/tweaking.

You are not longer running dual channel with 3 sticks - not worth it.

100% disagreed.

Flex Mode.

And even if there was no such thing as Flex Mode, Vista with 4 GB single channel > 2 GB dual channel, no question about it.
 
Intel can also run normal dual channel if the amount of ram in both channels are equal. 2+1+1 gives that configuration (if installed correctly)

Wait, so if I put my 1GB sticks in channel 1 (slot 1 and 3) and put the other stick in the 2nd or 4th slot, it runs dual-channel?

Yea, I might just underclock them all to 533 speed because the patriot is 2.2v and my adata is 2.0v to reach the same speed.

edit: i suppose I could just run them at standard 5-5-5-18 ddr2-800 1.8v or whatever.

But that feature is only supported on some motherboards, and according to his manual for his Gigabyte P35-DS3L motherboard, his does NOT support that feature. It does support Flex, though.

Sometimes such manuals leaves stuff out.

Flex is for a minimum of two sticks. Flex is enabled, when the amount of ram in the two channels is not equal.
