Memory Advice

I am building a new pc and I have a query concerning memory and FSB.  The config is as follows:

- Asus P4C800-E Motherboard (4 x Dimm slots)
- Intel Pentium 4 3.066Ghz Prescott (800Mhz)

My first question is concerning memory...  to operate in Dual Channel mode it is recommended I purchase the identical memory.  I am needing at least 2GB memory with an option to upgrade.

Would you therefore recommend purchase 1GB x 2 leaving option for upgrade or 4 x 512MB cheaper but more expensive to upgrade.

Also I have checked the Corsair Web Site for compatability and they have come up with DDR-550 and DDR-500 (XMS-4000).  However the Motherboard manual shows no mention of this.  Is this new?

Anything special do I need to do to ensure that FSB & Memory match?


1 Solution
You might as well leave the option open for the future and get 2 x 1GB sticks.  Keep in mind using all of 4GB can be a problem for some motherboards, if you intend to do this.  If you get the name brands, you should have no problems: Corsair, Kingston Hyper-X, OCZ, Mushkin, or Crucial.  Crucial guarantees their memory will work according to recommendations of their configurator: http://www.crucial.com/store/listparts.asp?Mfr%2BProductline=ASUS%2B+Motherboards&mfr=ASUS&cat=RAM&model=P4C800-E+Deluxe&submit=Go

DDR-500 and 550 are DDR2 and not compatible with your motherboard.  You just need to get PC3200 or higher and it should work at 800 FSB (I got PC4000 and it works fine, and I overclock).
