Motherboard Testing Methodology
I recently looked at how well an AMD 790FX system holds up to a more modern Core i5 setup. The 880G Northbridge can't hold a candle to the 42 available PCI Express lanes on the 790FX, but we're limiting our tests to a single video card in a single x16 PCI Express slot, so that aspect is a fair match. The Core i5 system is generally going to offer superior performance, with 4 cores, better performance per clock cycle, and what is arguably the best integrated memory controller on the market. Hey, nobody said it was going to be a completely fair fight...

I took the ASUS M4A88TD-V EVO/USB3 motherboard to two different levels of stable overclock for these tests. The first, at 3.8 GHz (225 MHz x 17) I got easily without raising the CPU voltage from the default value. I then raised the voltage just a bit, and changed to 230 MHz x 17.5 for a 4.0 GHz overclock. I concentrated on raising the system bus instead of the multiplier for these trials, because this is a motherboard test and I wanted to see how well the Northbridge would handle the higher bus speeds. I didn't go wild, like we used to in the Core2Duo days (400 MHz on P35's, remember...?), but instead used what folks without an unlocked CPU multiplier might use in the real world. Memory timings were kept at their rated timings of 8-8-8-24 for all tests. I also used the standard voltage spec for the OCZ Black Edition DIMMS, 1.65V.
