7901 ultra 2 sticks limit!

rapid64k · 16 Jun 2008 at 20:55

Has any one noticed that the Nvidia 790i ultra limits you to only 2 gb dd3 ram if you go over 1800mhz.
if you check the list it says you can use 4 sticks of ram for anything under 1600mhz

check it out and tell me what you think gents, if im wrong my bad, but it just caught my eye.

4gb of DDR3 will work over 1600MHz it just need tweaking to get stable, Best to us 2 x 2gb sticks aswell

thanks for the reply. Ok so what would you recommend 2x 2gb sticks or 4 x 1 gb sticks running at 1600mhz?

Im told the later Asus ones are fine, remember there is 2 types of 790I, think 1 is a Ultra or such.

2x2gb sticks would be best

Thanks 2x DDR3 ram = 2gb it is then.
people have advised me that when using vista 64 you should have 4gb or ram! how does that sit with using 2 gb or ram?

get a 4gb kit consisting of 2 2GB sticks of RAM.

edit: Also, that table, isn't it only displaying the RAM moduels that use EPP? It's not actually the limitations of the board by setting timings manually is it?

from the table: "SLI-Ready DDR3 SDRAM DIMMs for NVIDIA nForce SLI motherboards supporting EPP 2.0"
