It's time to upgrade my system memory, I currently have one 512MB ddr PC3200 (400Mhz) but would like two 1Gb sticks, my motherboard is an ASUS P4S800, I've done some research into this but no one seems to recommend 2Gb

This is from the Dell website :

System Memory Configuration: Standard Memory: N/A Maximum Memory: 3GB using 266MHz DDR modules
2GB using 333MHz DDR modules Expansion: 3 Socket(s) ( bank(s) of ) Host Type: Motherboards Class: MotherBoards Central Processor: Bus Architecture: AGP/PCI Native O/S: (N/A)


This is from the Crucial website:

and

Your MemoryYour computer currently has 512 MB of memory installed; and will support up to 3072MB.
Slot 1 512 MB Non-parity DDR PC3200Slot 2 Upgrade this slot Slot 3 Upgrade this slot You have 2 empty memory slot(s) out of 3 total memory slots.




I would like one of these

Is there any problem running two 1Gb at 400Mhz on this motherboard

Have you had a look at the ASUS website? They will be able to give you a list of compatible RAM for that Model of Motherboard. And if you need a BIOS update as well.

I presume you used the Crucial Memory Advisor plugin that scans your system and recommends only RAM thats guaranteed to work with your mobo. If you want the top spec stuff then I think Crucial have a range called Ballistix which is the high-end memory.

I might be wrong but I dont think it matters if you go with higher clocked RAM, even if your mobo wont support it, it runs at the highest available speed. The main problem is youre paying for something you dont need.

Send Crucial an e-mail and ask them direct. They are very helpful and very quick to reply.

OK I'll try that

no point really upgrading to 2 gigs of ram just buy another 512mb, best save money and get a ddr2 motherboard and fully upgrade everything

DDR2 RAM at the moment isn't worth upgrading too, as it shows no benefit over DDR1.
