Will this memory work on my ASUS P4S533....

[.:mike:.]

I have an ASUS P4S533 (Rev 1.03) m/b and I would like to upgrade the measly
512k and add another 1024k. Sorry for the newbie question but I have never
upgraded my memory before!

Will the following memory work with this motherboard:

http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=27150

Memory info from motherboard manual:

Is it better to get a single 1 gig stick or safer to go for 2 x 512k?

Thanks.

The manual says you are limited to four banks at DDR333 rates.
If you really need 1.5GB of memory, I would buy a 512MB DIMM and
a 1GB DIMM, and place the two sticks in slot 1 and slot 3
respectively. For the 1GB dimm, buy a memory product that uses
64Mx8 (512Mbit) memory chips - these are the brand name 1GB DIMMs
and not the 1/2 price 1GB DIMMs based on stacked memory chips.

Example of a module using 64Mx8 chips...

Another alternative would be to find single sided 512MB DIMMs,
but that amounts to buying a 1GB DIMM that is half populated
with 64Mx8 chips. A DIMM like that will not be too common, and
it will be easier to find a proper 1GB double sided DIMM with
(16) 64Mx8 chips on it.

A cheaper solution would be to use (3) 512MB DDR266 DIMMs, but
then the memory bus will be running a bit slower. You can
certainly buy PC2700 DIMMs and run them at DDR266, as memory is
backward compatible with the lower rates. Even PC3200 DIMMs
can be "turned down" and used on your board. The PC3200
implies the maximum speed it will run at, and all lower rates
are also possible (DDR400, DDR333, DDR266, DDR200).

To review (first two options are the cheapest):

Banks Slot1 Slot2 Slot3
1GB total 4 512MB_DS 512MB_DS DDR333 rate
1.5GB total 6 512MB_DS 512MB_DS 512MB_DS DDR266 rate
1.5GB total 4 512MB_DS 1GB_DS DDR333 rate
1.5GB total 4 512MB_SS 512MB_SS 512MB_DS DDR333 rate

The first option looks to be the most practical.
