Hello all! I'm still sort of a new to all this, so I'm looking for some help. I have an Asus A8N-SLI Deluxe mobo. I currently have two 512mb sticks of Corsair ValueSelect DDR. I'm purchasing two sticks of 1gb G.Skill DDR. What I want to know is, can I use all four sticks with this mobo for a total of 3gb of RAM? I seem to remember the A8N-SLI Deluxe having some issues when 4 sticks are placed into the mobo. My second question is, if I am able to use all four sticks, will I be able to use them in dual channel? Third, anything else I should know that I probably don't? Thanks for any and all help.

have you read the manual or checked the manufacturers support website ?

orbital Is right read your manual or check online for your motherboard specs. But to get you started it would be advisable to not put your 512 chips in, if they are a slower frequencey than your 1 gig sticks. Secondly 2 gig is good enough for anything that I know of so why need more. I mean games like FEAR and stuff should run great as long as you have a decent gfx card. You could put them in but if you palce them after your other sticks in terms of DIMM Slot 1, 2 etc the system may crash due to a timing mismatch. If you want more buy the exact same chip again I suppose :p hth regards Lupin3rd

The reason that I asked the question is that I don't want to see these two sticks of Corsair RAM go to waste sitting somewhere. I figure, if it's possible to use all four sticks for 3gigs, then I will. But if there is going to be an issue, then I will just use the 2 sticks of G.Skill.

If the 512mb modules run at the same mhz as the modules you are getting, there is no reason you can't use them. I believe the way it works is the same as in other ram situations - the bios will set itself and the mboard to the capabilities of the lesser capable module(s). All your ram must be dual channel in order for you to benefit from the extremely tiny advantage of dual channel. When you mix dual channel and single channel it runs overall the same as it would if it were all single channel, so there would be no advantage to two modules of 3 or 4 being dual channel.

As far as buying G.Skill ram, you must make sure it will work in your particular mboard model before you buy it. If you can't take your computer case with you and try the modules locally before you buy them, the main web sites http://www.gskill.com/ do not have any way of looking up whether it will work in your particular mboard model. If you are stuck on using G.Skill ram, what you can and should do is go to the Forum and ask them whether the ram modules you were thinking of getting are compatible with your model, or ask them which of their modules work in your model.
