Gigabyte EP45-Extreme Review



In order to push this Gigabyte EP-45 Extreme motherboard, I'm going to put it through a very tough group of benchmarks. I'll send it through various scientific, real world, and video benchmarks, to see how well this motherboard fares. There will be three other motherboards that will be compared to this EP-45 Extreme from Gigabyte - the ECS P45T-A, the ASUS P5QL-E (P43+ chipset), and the Gigabyte X48-DQ6 motherboard (X48 chipset). All components will be set to run at their stock voltages, timings, speeds, and frequencies. Let's get to testing this motherboard!

Test Setup: 


Comparison Motherboards:



Overclocked settings:

  • Processor: Intel Core 2 Quad 9450 500x7 / 3.57GHz
  • System Memory: Mushkin Redline XP2 8000 2 x 2 GB 5-5-5-18

After hours of overclocking, I finally realized that the inability to unlink the memory and CPU was really making a difference. The Mushkin XP-8000 set of RAM I had in the board couldn't be pushed over its rated 500MHz, thus leaving the maximum FSB I could achieve at 500. Now, a FSB of 500 is actually a very good overclock on a quad-core processor, and I'd love to see how far I could take this motherboard, if the memory wasn't holding me back. I haven't had too many motherboards that have made it to 500, so I was quite impressed with this motherboard.
