I'm just pricing (for grins) a new quadcore PC and came across DDR3 RAM for PCs. The timings are 7-7-7-21 @ 1066MHz (PC3 8500). Is there much of a performance gain over DDR2 RAM?

Live long and BOINC!

And proud of it!

The last article I saw (anandtech?) indicated little to no difference, but that will change over time as always.

Right now, not worth it IMO.

Little to no difference initially, but AnandTech did state that as DDR3 speeds increase and latencies lower, it would be more beneficial. AnandTech though it would be at least a year off for better speed and latencies, but you can now find DDR3-1600 as low as 5-5-5-15 IIRC.

Now, if you can find a MB that can support ram speeds that high, then that's another thing altogether. Perhaps in a few months time (Dec. or Jan.)?

Not worth it from a price standpoint either, when you compare the high prices against the little to no difference its making in benchmarks. Even enthusiasts would be better off looking at the performance DDR2 chips right now.

Just like during the DDR to DDR2 transition, you'll just have to give it a few months before prices go down and for performance to go up, probably by next year.

Not worth it from a price standpoint either,

3 times the price for no more than a 10% improvement in benchmarks (not noticeable performance) isn't good value IMHO.

Keep in mind everthing was great once. PS- Check the price!

I am currently running Corsair Twinx 5-5-5-15 (DDR2 8500) and it works well.
It also runs at 1066, and has been for almost a year now.
There is usually some benefit eventually for buying the very latest future fishing lures;)

When we finally figure it all out, all the rules will change and we can start all over again.

DDRIII 1600 with low CL are available. I saw 7-7-7-15 working.
DDRIII is the way to go.

True, but cutting edge is expensive.....
I think most should wait 'till DDR3 becomes more mainstream, and then the price will start to drop.
So nice to hear from you, who?!!

"Time is simply the mechanism that keeps everything from happening all at once."

Good to see that you are still around Who. I have been watching your RAC climb, impressive. Looks like your work is paying off. Hope that you do favor us and release the code soon. I for one would rather see intel chips on the top of the computer list, instead of Mac's. But wait Mac's are intel chips too these days.
While I agree with you that DDR3 does have better performance, I have to agree that the cost benifit is not there yet. I am sure it will be soon.

Well, I ll be at IDF with my code. My network got some trouble at home, I had to added a hardware firewall, due to net attack (regular router was too weak), i got starved of workload last week end because if this.
it is all back online, my RAC will climb more from now on.

This is where to get Bins :)

Hi Francois,

Got a few red-x pushes calling this an advertisement. Just wanted to let everyone know that I don't consider this an ad just because it links to a commercial site. It would be an ad if it were more directly touting a product. However, given that it's a link to your own employer it's a borderline case.

I'd also like to point out to anyone who intends to distribute a SETI@home application that you are bound by the GPL and must provide source, the README, COPYING, and COPYRIGHT files and whatever project files/makefiles/compiler flags that you used to build the binary. Either that or you can set up a web site where the source will be available to anyone for the next three years. It's usually easier just to provide the source with the binary. (The COPYING/README/COPYRIGHT files need to travel with the binary, however.)

In theory alternate distribution terms are available from the university's IP department. However, thus far, no individual or company has successfully negotiated such terms even if we (the SETI@home team) have given our approval. That's probably because we would need compensation for the time it would take us to strip out GPL licensed code to which we don't hold copyright (i.e. FFTW, ASMLIB)
