Any DDR2-800 out there that can run solid at or near 3-3-3 timings?

I'm guessing that since nobody has been raving about any stable CAS3 DDR2-800 that it isn't that popular.

And how much of a noticeable real-world performance difference is there between 3-3-3 timings and 4-4-4 anyway (at the same speed)?

cas3 usually takes more voltage than I am willing to give my memory anymore. My GSkill will do it, but requires over 2.2v to be stable.

Any RAM that has Micron D9-GMH or GKX IC's will do 3-3-3-8 @ 400 Mhz/800 DDR, but that requires 2.3-2.4v of vdimm, which is too much for everyday use, IMO. This RAM has really good timings, for the price. It doesn't overclock anywhere near as well as the D9's do, though.

There's none real-life performance difference ( except a small one in some File Archiving programs ) from changing your memory timings or frequency.
If you wanna see measurements to prove that, check my site's first memory roundup where we kept the CPU Frequency & FSB stable, and changed only the timings and/or the memory timings

The Corsair PC6400C3DF will do CAS3. The tested voltage for that, as noted above, is 2.4v. I have heard of "some" of our sets doing CAS3 at 2.2v but, they are rare and that is not guaranteed.

I guess i'll stick with CAS4 spec memory then. I don't want to risk seeing what happens to my memory if i run it at high voltage everyday.

The G-Skill mentioned above looks pretty good. Also i've seen a few AT'ers recommending the Crucial Ballistix. The latter uses the D9 chips so i think i just might go with it.

There is a benefit, albeit slight. I can see it becomming important with Penryn and later CPUs to have bandwidth ready. Also I suppose in Vista when everything is loaded to memory waiting to be called upon (superfetch) it could also help slightly.

Show me, show me!

Benchmark variation = +/- 1FPS

Other benchmarks can be found on my first DDR2 Roundup, can you see a benefit ? 'cos I don't.

And if you think that with Wolfdale/Yorkfield you'll see any difference between DDR2-800 5-5-5-15 and DDR2-800 3-3-3-4, think twice

go checkout xtremesystems.org seriously...have you ever looked at the memory section there?

btw: gaming does not stress memory...or hell even CPU these days.

Thanks for letting me know of that awesome site!
Oh sh1te! Hold on...I'm already there, and gimme just another sec...Xtreme Bandwidth ( aka Memory Overclocking Section ) as you said...is where most of my threads are, with tests at extreme memory speeds.

P.S. Do you consider SuperPi, Hexus PiFast, 3D Mark2001SE & AquaMark as real-life applications that benefit from better RAM performance ?
Because we're talking about real-life performance, where the only applications that benefit from higher memory performance are some File Archivers.

I rest my case now

winrar,winzip benefit greatly from increased bandwidth. I use these alot to compress and decompress large clusters of anime.
