Gigabyte X79S-UP5 Review
We'll be running two very different tests today. On the one hand we'll be using the Xeon with registered 1333MHz memory for our 'stock' settings. We all know how good the i7-3960X is, so repeating the stock results of that wont teach us anything new. Our other test will be using the i7-3960X at whatever overclock we can coax from the UP5, alongside the Dominator Platinum running at 2133MHz. Got all that?

Now we come to the crunch. The power phases on the UD5 gave us fits it was so woeful. The ones on the Z77 UD5 aren't much better. So have Gigabyte finally turned the corner?
Yes and no. Always a handy answer we know, but bear with us. Firstly the UP5 managed to get 4.6GHz out of our i7, which isn't bad at all. It's only 150MHz shy of the much pricier Rampage IV Extreme and that bonus was acheived by overclocking the BCLK. So far so good. Then you look at the core voltage, 1.392v, and we know we had 1.45v set in the BIOS. Even with every anti-vDroop measure available to us the UP5 is still droopier than a groom on his stag night. This was one of the main problems with the X79-UD5 and we would have thought with a good 12months they would have got this fixed.
