however, i could also choose 4GB of RAM at 800mhz.

both cost the same amount.

now, why would it recommend the slower RAM?
Depends on the speed of the front-side bus. You want RAM that’s either the same speed as the front-side bus, or an even multiple of it.

thanks, that’s exactly what i wanted to know.

so if the FSB is 1333, then 667 is the way to go, right?

667 minimum. it’s probably the most you’ll need on that dell unless you have plans to upgrade on any of Intel’s planned 1600FSB cpu variants.

same price, i’d get the 800

op, were there any other diffs?
2×2GB vs 4×1GB sticks? Does Dell specified ram brand?
Why would Dell recommend the 667 over the 800 if they both cost the same? The 800 must not cost Dell any more, or else they’d just pass on the cost to the customer, so there must be a benefit to using the 667 with that particular system — and I think the rule of thumb I gave the OP explains why.

nope, no difference.

both are 4gb ddr2 sdram 2 dimms. except one is running at 667 and one at 800.

i will stick with the one that is half the speed of the FSB.

.

Faster ram is kinda pointless if it isn’t a multiple of the FSB. It won’t give you a performance increase

at same price, timings, and voltage requirements,… i don’t understand why you’ll waste the free overhead, but it’s your call.
it’s probably generic Nanya chips anyway.
Yeah ^ why not let the 800 ram just run at 667? It’s possibly a higher quality chip right?
