Hi, I need help here with my ram. My current Motherboard is a Asus P4S533. I currently have 1 stick of 256MB of ram. I think it says it only runs on a max of DDR333mHZ, but im not sure. If I buy a 512MB ram, and it e runned with my 256 MB? Can someone check if my motherboard works if I buy a 512MB Ram. Also, if I buy the 512RAm, and I get one that is PC3200, will my motherbaord downclock to work with my 256MB ram? (PC2700) Help me~

SDRAM and DDRAM COMBO P4S533-MX has two DDR sockets and two SDR sockets that support up to 2GB non-ECC PC2700/PC2100/PC1600 or PC133/PC100 SDRAM DIMMs That's what the manual says (pasted) I allways keep the memory in line with the cpu fsb where I can, I believe if your m/board had supported 3200 it would have run at pc 2700 speed. but it doesnt, waiting to hear different

My motherboard right now, doesnt support PC3200, it only supports up to PC 2700 (333mhz), but if I buy a PC3200 type ram, will my motherboard downclock to work with my PC2700 256MB Ram? Help me~

ron- Correction, my motherboard isnt a P4S533-MX, it's just a ASUS p4s533, it only has 3 slots, and currently i have a PC2700 256MB Ram. Help me~

yes it will work, but personally id get a tech to match it with your old stick to avoid compatability issues, just take your current stick to a decent local pc shop and tell him you want a matched stick, even if he cant get the same brand he should be able to match the speed and density Q-TEC 550 Watt PSU MSI VIA KT4AV-L 2800+ Barton 512 DDR333 GeForce4 Ti 4200 128Mb Aero 7 Lite 80Gb Samsung ATA133 HDD 120Gb WD ATA100 HDD LiteOn LDW-851S LiteOn LTR-52246S
