With the QX9650 running at 4GHz and the Crucial Balistix memory at 1600, the WorldBench number was 138 which I believe is a record but again only one pass completed with all tests run. The second and third passes failed to complete the FireFox and FireFox/Windows Media Encoder multitasking tests.
I'm trying a couple of passes of those two tests alone to see if I can discover the exact nature of the failure. But then I'll be pulling two sticks of the Ballistix and giving it a go at 4GHz/2000MHz. The 2000MHz memory worked fine when placed in slots 2 and 4 in a 2GB configuration.
Later...
The previously described 2GB at 2000MHz didn't work. It didn't make it past the second test in the first pass.
Kingston sent along 8GB of 1800MHz memory that I also tried but that didn't make it through WorldBench either at that speed. I'm thinking that the 8GB of Corsair is what we'll ship with. I was going to visit Las Vegas this week for my Aunt Perl's 80-something birthday. But I'm now sick as a dog with some sort of sinus/cold/flu thing and that fries that plan unless I'm significantly better by Thursday. Can't be infecting an octogenarian. Actually, I'm not big on the Typhoid Manny deal on any front. I really hate it when people show up for work, knowing they're sick, and risk infecting their coworkers. If you're sick, stay home.
More when I'm feeling better.
Cheers, Jon
P.S. I haven't heard if the winner has responded yet and I'm assuming I will. Maybe there's still hope for you guys.
P.S.S. Ignore the P.S. Sorry to raise false hopes.

I am with you 100% on that one. To bad many of the "powers that be" don't think like that. While it is a shame to lose someone and their productivity to illness, I would think that we had more people actually use sick days, then maybe illness would not spread through offices as much and in general things would be more productive.
Regardless, hope you feel better. Being sick in a real bummer. I don't do the whole flu/cold thing well, personally. One secret that I have found when I get super congested is that sleeping in a Lazyboy chair helps (i.e. not lying flat). Get well soon! And don't get too many germs on the Dream machine!
