Test Setup and Overclocking
Test Set Up
When testing a CPU like this the hardware has to do it justice so we pulled out the old faithful ASUS Rampage 2 Extreme, and after a quick flash to the latest BIOS she was ready for some 6 core abuse! At the same time its no good testing a 980X with a 3850, so the GPU of choice was a 5870, these have been tested many times on OC3D so we have many results to compare to see if the extra cores do indeed make a difference.

Before we get on to how this Gulftown 980 overclocks let's show you the default CPUz so you can compare.
First port of call here is the base clock, but its really quite a simple affair, you drop the multiplier down low and gradually increase the base clock to see what the maximum the CPU has to offer. At a 16x multiplier our CPU managed a 220 BLCK at stock 1.25v volts, surprisingly increasing the Vcore up to 1.325v and also increasing the QPI made no difference to what the CPU was willing to relinquish.
The next port of call was to try and find the CPU's maximum MHZ overclock, 4.4ghz (22x200) came about relatively quickly but with a little more tweaking and a 1.325vcore we managed to coax out 4.5ghz (180x25).
Overclocking is a great past time to see what you can achieve from your system, but to many its no good unless its as stable as it would have been at stock. Finding the sweet spot here is a timely affair and requires the patience of a saint, and plenty of free time...... Normally. After an hour of playing around with settings tweaking this and trying that we found the sweet spot on our CPU was 4.2ghz (210x22) with a Vcore of just 1.3v and the QPI set to 1.375v the chip was happily sat playing with Prime95 like they were the best of friends.
Not quite believing that 6 individual cores on 1 die were all running stable at 4.2GHZ I decided to leave prime running overnight. 14 hours later I came back and it was still happily running at 100% across all 6 cores and 12 threads, so I was happy enough to call it stable and started our benchmark testing.
