Hi All - does anyone know of any issues with the FX-8120 cpu? We built a system with a GA-970A-UD3, 32gb of Crucial ram, 1tb Seagate Barracuda SATA-600, Cooler Master 550w, XFX 6670 2gb video. System ran great for 2 weeks, amazingly fast, fast boot times, AutoCAD & Outlook ran fast, etc. Customer returned complaining that it went from fastest computer ever to slower than dual core systems. We've swapped power, memory, cpu, motherboard, hard drive (brands & models changed of each) and basically if we swap out to a FX-6100 them system runs great again. (we're basically looking at boot times, and AutoCAD startup and performance and Outlook performance). Everytime we go back to a 8120 system runs bad again. Temps, Voltages all look good running bios defaults & 1333mhz ram. Latest (and not latest) bios for board, all windows updates, malware/virus/rootkit free. Know there were some hotfixes for Win7 64bit, are there other unofficial hotfixes or anyone have any ideas why 8120 on a 970A chipset runs so bad?

Do you see all cores in the resource monitor? And while AutoCad loads do they work? Anything in EventViewer that points to the problem? Try http://www.hwinfo.com/ or any other tool to monitor the core frequency.
