Since your mobo support max of 4GB, u can either go for 4x1GB or 2x2GB configuration.
In theory, even if u put 4x2GB sticks, it should still work but only be able to use 4GB and remember, Win 32bit version can only use max of 3GB anyway.
IMO, it would be better to go for 4x1gb since u only need to buy an extra pair of 1GB if you really insist on upgrading but the performance improvement won't be much.
Just make sure u get DDR2 and not DDR3 sticks.
Hey man just wanted to say thanks for the help.My problem now is...well my real problem is that I need a new computer,I built the one I got now like 10 years ago ,,,yeah ,yeah stop laughing.It was fine till about 6 months ago.Any way...I got 4 sticks of 1gb corsair.It's cheap stuff because like i said it's old .im planning on putting together as haswell based sys soon.I put the 4 1gb sticks in and after my sys goes through post...it stops.does nothing and i sit staring at the asus logo on my screen.i put my original 2 sticks back ...everything works.It's really slow ass ram and I'm thinking i might need to change the cas lat in the bios before i stick the new sticks in.Any clue?it's corsair value ram...not very right now. 1gb sticks ddr2 667 pc2-5300 cas lat is 5-5-5-15 1.8 vt..thought maybe voltage as well...any way thanks for the help man you rock...raykat
As far as i see, the new sticks shouldn't be a problem since they are in typical DDR2 spec. Since mobo support DDR2-711(FSB1066)/DDR2-600(FSB800)/DDR2-533(FSB1066/800) and the one u have is DDR2 667, it would work at 600MHz speed.
In order to test the new RAM, slot them in 2 at a time to old RAM slot and boot up and see whether they work at all or not. If not, try next 2 and follow by swapping the stick from 1st set with 2nd set etc.. If it doesn't work then i'm afraid that the new RAMs might be defective.
If the above method works and confirmed that new sticks are working fine, my advice would be to clean out the memory slots with compressed air or with a low setting on vacuum cleaner since u haven't use these slots for so long, i'm sure there will be dirts on the spare slots and covering the pins.
Make sure to seat the RAMs properly and firmly till u hear the click sound.
Don't change the CAS/LAT before u r confirming that the RAMs are working fine. IMO, Using ASUS AI Booster program that come with the mobo will save time and trouble.
Hope it solves ur problem.
