Sorry to burst your bubble, but if you check around the web, it seems the OLDER boards are the ones with the ICS chips. I am pretty sure Asus is aware of people OCing the ICS boards and are only putting Cypress chips on the latest ones. They are probably saving the ICS chips for a new model board supporting PC1066.
How do I know Asus is on to this? I am in Japan, and last weekend, I saw one store liquidating two stacks of P4T-E boards for $94 US. They normally go for $177. I checked the boards out and they all had ICS chips! They were labeled 'junk' boards with no Asus warrantee. All brand new.
I checked all the stores and they were now selling a newer lot P4T-E with a different box label, and they all had Cypress chips.
I couldn't resist and picked up one of the $94 P4T-E boards, as a backup to the ICS board I already have. That one is a used board but with Asus warrantee. I also was able to find a Malay 1.60a at one store, for $144 US. Man, I got lucky that day.
And tell ya something else, I notice on the newer batches of Northwood 1.60a, the label on the retail Intel package does not specify location of manufacture!!! So now you can't pick a Malay chip; you don't know what's in the box. The only other 1.60as around were the Costa Rican chip.
