THE MYSTERY OF WHY a version of AMD's upcoming 64-bit processor will come in 940 and 939 versions, first revealed in the INQUIRER, appears to have been partly cracked.

Rob Squires at AMD Zone said that he had a chance to ask AMD about the pin configurations, and first of all the chip firm has now officially confirmed there will be 940 and 939 versions of the chips.

AMD said that the extra pin is needed to work on six layer Opteron motherboards. As we said earlier, the chips will first start shipping in 940 Opteron configurations, and they will start to appear after the official launch date in September.

Our information is that will be in the first quarter of 2004. The 940s will, no doubt, cost a little bit more because of the price of the extra pin.

According to Rob, AMD said that the extra pin is required for simultaneous multiprocessing, because, apparently of SMP/hypertransport necessities.

There's more here. µ

Authorities in several countries raided Megaupload recently, shut down all of its services, seized hundreds of servers and arrested several of its executives on criminal charges.

Do you think the move was justified?

Yes, companies should suffer an immediate death penalty upon being accused of copyright infringement.

Yes, the coppers said the company was breaking the law so it must be guilty.

No, the company and the people accused are innocent until proven guilty.

No, the company had millions of customers who have been harmed by having access to their data files cut off.

I don't care, I never used Megaupload anyway.
