Asus P5Q with a Q9650 installed Windows 10 64bit without issue. Fresh install, wiped drive of Windows 7 which was running for years without issue.CPU-Z output:Family 6, Model 7, Stepping AExt Family 6, Ext Model 17, Revision E0Instructions include the required: EM64T (if you are trying to install the 64bit version of windows)P5Q Bios 1611 Thank for the update. So maybe its not the Q9650. In that case. I am out of ideas as Windows 10 wont even download. Perhaps I'll go back and read the forums.

Having a problem trying to install windows 10 onto system with Asus P5B m/b and Intel Core 2 Quad Q9650, says CPU not supported. Checked via Intel CPU software that says PAE, NX, SSE2 all supported, could be related to VT-x, but BIOS (2104 - latest) says Vanderpool (old Vt-x?) enabled.Also, as an alternative, could windows 10 be installed via Oracle VirtualBox or something similar to workaround this problem?Same problem with the same CPU. Oddly enough, The PC had windows 10 with an older core 2 duo but when my father was offered a free core2quad and some RAM for free, the PC would no longer boot. Upon installing 7 and trying the free upgrade (ending in a couple weeks on july 29th 2016) the pre system check said the Core2Quad 9650 wasn't supported because it didn't support a certain feature needed for windows 10.
I wish i wrote down the name of that exact 'feature' but, either way, it seems very bizarre. I was considering moving him back to his Core2Duo (for what he uses it for, the RAM would have probably been enough) but now hes taking about just getting a new computer all together.I will do some further investigating and if I find anything substantial, I'll come back and update this reply but as for now (July 19th 2016) it seems Microsoft will not be supporting this CPU for windows 10 on a claim of the CPUs inability to completely 'support windows 10 functionality' and with that type of response, I doubt it ever will (unless that message was wrong somehow).
