Performance of running unsynched ram on Nvidia 6xx boards?

[Hajpoj]

What kind of performance hit would I expect if I picked up a 6xx chipset board and used my cheapo DDR2-533 and OCed a E6400 to 3.2GHZ?

Instead of using DDR2-800?

bump...

I do not understand your question at all.

On the nividia 650 ot 680 chipsets you don't have to run the ram 1:1 or 4:5. You can for example set your FSB to 400 and use ram at ddr2-667. What kind of performance hit does this cause?

good question, go find out for us :D. Sorry can't help you. And isn't it called asynchronous?

well, from everything ive seen in the past, it will cripple performance. Sure the CPU is running faster, but the ram would slow it down by not being able to feed the cpu data fast enough for it to truly shine.
A good example is when OCing the CPU with a low RAM divider (to keep it out of the picture so you knwo what the cpu alone can do) you run Pi, you get a time. Lets say like 30 seconds for the sake of a number. Then once you tweak the ram to run its fastest, its possible to gain a second or so from that alone from what ive seen.

This is about what I'd expect (one becoming a bit of a bottleneck), but it's a far cry from what *I* would describe as crippling. Of course, I don't spend a lot of time fretting over minor differences in benchmarks (which puts me in the minority here at XS!).
