While at Computex I noticed that the PQI booth had some 256mb DDR600 modules up and running. They were happy to show me the modules and talk about DDR600 performance, but the modules were being run at 283MHz. Last time I checked that was DDR566 and not DDR600. Oh well I got a laugh out of it. Here are the photos if you want to take a look.
The modules in action... note the LED's like Corsair's PRO series.
I just went to the PMI website and noticed that they have DDR 566 PC-4500 Dual Channel Series memory
listed. This would be correct, but still a decent sized error for a trade show.
