Will DDR2 800 memory work with DDR 400 supported board?

Was planning on building a micro ATX computer for my office since I have a AMD 4000+ socket 939 sitting here. But know I'll want to upgrade it eventually and the path will ofcourse require DDR2 memory. So instead of wasting money on more DDR 400 memory can I get some DDR2 800 and will it work? Thanks for the help.

Thanks fo rthe info. Thought that might be the case. Guess I'll rethink the build a bit. That 4000 is such a nice chip though seems a shame to not use it.

ddr dimms are 184 pin and have one notch inbetween - ddr2 are 220 pin and have two notches much - so the sockets that they go in are not even remotely similar

Please not that because the memory controller is ON the cpu of your 4000, that, your ram, and your motherboard will have to be ditched if you plan on upgrading to AM2.

If you are REALLY that intent on keeping your ram though, there are some Core 2 Duo boards that support DDR1.

Yes, figured on ditching the mother board anyway as figured upgrade would be core 2 duo or whatever is leading in about a year. But when I start to then add in the the cost of say memory which I will also need to ditch then I'm thinking it is probably best to sell the 4000 and just buy a c2d now for the build. Or I guess I could roll the memory into my home system for 4 gigs. The progression of parts seem to be my home system is always ahead of my office so I would push my old equipment to the office. But really the office system could get a few good years on that chip and build no problem. More thinking....

You can sell your old stuff on eBay for good cash. Think about that.
By the way, sell the parts individually. And my mother owns an eBay store, so I have some experience with this.
