DDR333 RAM running at DDR266

[Dexter]

I figured the folks in the overclocking forum may have the most experience with this, so here is my question.

We are configuring a system for a client. It has an Intel motherboard that suppports 533 FSB, but we are putting a Celeron 1.8 GHz processor in. So the processor therefore only runs at 400 Mhz FSB. No problem yet. So we had two sticks of 256 MB DDR RAM @333 Mhz left over from a previous job, and stuck those in. Because the FSB is at 400 Mhz, the 333 Mhz Ram gets downgraded to 266.

The system appears to run fine, and in fact, the mobo manual even mentions this procedure. What I want to know is, has anyone run a system with 333 Mhz RAM downgraded to 266? Have you had problems, or does it work fine? I did some Googling on this, and could not find mention of problems running this config, but I don't want to send a lemon off to our client.

Any real-world feedback?

Thanks in advance.

I dont have any exp. on Intel with this, but i have used it on Amd with no problems at all. On my first amd board, i had a Xp 1700 pally that i couldn´t unlock and the memory was specified to do more than the cpu could take without changing to much on the devider. I am 100% sure you won´t have any problems at all.
Infact, if anything, you have an even more stable system.

Are you able to try out that system anything? Im thinking of the deviders. See if you can find a devider/fsb combo that gets the fsb up at the sweetspot. Just a thought.

The memory is backwards compatible :)

It will work just fine and as Mack very knowledgably put, will probably be more stable as you aren't stressing it to the limit it is specified to :)
