quad core only operating on 2 cores
About 8 months ago I put together a computer running Vista ultimate 64 on an EVGA 780i, 8gb ram, and Intel E6850 (3.0 dual). Everything went smoothly, and it hasn't had any huge hiccups since. About 2 months ago I picked up a Q9400 (quad 2.6). I shut down my computer, installed it, and re-booted. The BIOS detected the 4 2.6 cores in the POST. Windows did a little firmware fiddling on its own as I'd expected, and continued to boot normally. When I opened the task manager to take a look at the performance, I saw it only had 2 cores displayed. Puzzled I checked the device manager, and under processors, it shows 2 'unknown device' entries. Now, the 2 cores it foes find work fine and just marginally slower than the 3.0's i had before, so I didn't immediately try and get an RMA or anything (I'm not sure if its a hardware failure or something else), but due to some insane scheduling conflicts, I didn't get around to fiddling with it or getting an RMA replacement before the time limit expired. Anybody have any ideas? I've contemplated a fresh OS install, but I'm not too keen on it for now. -- Hippo |

Hello Hippo, I would try resetting your BIOS settings back to factory defauts to see if it can properly detect your CPU afterwards. Hope this helps, Shawn -- Brink *There are no dumb questions, just the people that do not ask them.* '*Windows 7 Forums*' (http://www.sevenforums.com/) *and* '*::Vista Forums::*' (http://www.vistax64.com) *Please post feedback to help others.* |

I bumped into similar once upon a time when going from a slower dual core to a newer faster dual core, suddenly only one core was functional. In this case, the motherboard's BIOS needed an update. (Do note the usual warnings about BIOS updates, specifically, it may turn your motherboard into an expensive and rather poorly designed doorstop) |

I would reset the BIOS first to default. If that did not work, flash it to the latest rev. You might want to repair install your OS. -- SCSIraidGURU Michael A. McKenney 'www.SCSIraidGURU.com' (http://www.SCSIraidGURU.com) |
