With its quad-core chips finally on the market, AMD acknowledges a compatibility problem with some circuit boards, reports News.com.
AMD spokesman Jake Whitman explained it this way:
What people have done, mistakenly, is paired a 780G (chipset-based) motherboard with the higher-frequency Phenom -- the 125-watt Phenom.
The story notes the higher-watt parts don't work with motherboards containing the 780G chipset, which need the 790 chips instead. It said some motherboard makers have been tweaking their products to deal with the problem. But it calls the issue just more woes for AMD in its rivalry with Intel.
