No, Intel is working on it and I would have to research when it will be available. Rest assured they will be releasing it soon. I am including two Intel links in this post. The first one deals with HT technology and the second deals with Duel core processors. On the Duel Core link there is a video that explains the difference between single, hyper, Duel and Duel with HT Technology. It is presented in a clear and concise manner. http://www.intel.com/technology/hyperthread/ http://www.intel.com/business/bss/products/server/dual-core.htm?ppc_cid=ggl| dualcor_b2b|k365F|s You may have to do a cut and paste on the above link due to the fact it wrapped. I hope this will help dispel any confusion you have. Sincerely, Frank Suszka netTek Computers [log in to unmask] _____ avast! Antivirus <http://www.avast.com> : Outbound message clean.
