Dear Mr. Arcadian
Could you tell me what are the differences between the two versions of the chipset, as far as I can tell the E8870SP component does what the scalability port was supposed to do in standard versions of the chipset. Or is it that two versions have been developped to keep cost lower for machines of 4 or less processors?
Thanks
