Thank you for posting on the Intel® communities.
I was reviewing your post and I understand that you are experiencing some problems with the Intel® Extreme Tuning Utility (Intel® XTU).
After checking the validated products for the XTU, I need to inform you that the Intel® Core™ ix-990X processors are not validated for the software.
You can confirm that by checking the following link. (Bottom of the page)
Additionally, I need to inform you that due to this product being discontinued, Intel Customer Service no longer supports inquiries for it, but perhaps fellow community members have the knowledge to jump in and help.
You may also find the Discontinued Products website helpful to address your concern.
That being said, please keep in mind that this thread will no longer be monitored by Intel.

Understood the weird part is that it worked once and was working on the old 920 CPU that was in the machine. Replaced 920 with 990x and it worked one time. Then the next day wouldn't load up.
