NotesIf you've been reading HEXUS today, you'll know that we have a plethora of AM2 coverage. We've also taken a look at a system from Evesham that's broadly equivalent and we'll be referencing it in the benchmarks that follow. We've also added in our own self-built Athlon 64 FX-62 system, as well as a unit based on the fastest Intel desktop CPU you can currently buy, the Pentium Extreme Edition 965.
EPP?We alluded to Corsair's EPP memory earlier.
Here's how it's manifested in the Foxconn nForce 590's BIOS. Note the SLI-Ready certification in green (well, it wouldn't be red, would it ;). Corsair and NVIDIA have jointly development memory that's designed for easy overclocking on an nForce 590 SLI motherboard. With the CPUOC set to 0%, meaning a 2.8GHz clockspeed, the PC8500-rated modules tell the system to drop the multiplier and raise the HTT clock, giving an overall memory speed of ~936MHz, above the 800MHz offically supported.
Et voila! The CPU's HTT clock is increased to 235MHz, which, with the CPU/6 ratio, gives an overall speed of........
In order to realise the memory's native speed, the motherboard needs to be set to CPUMAX, which then pushes the HTT clock to 266MHz and memory, consequently to ~1066MHz speeds. The current implementation keeps a 12x multiplier, such that an overall 3.2GHz clockspeed is required.
Corsair's EPP-supporting DDR2 SDRAM offers extra performance with automated adjustments.
The system wasn't quite stable at an overclocked 3.2GHz, but may well be with better cooling.
Let's crack on to the benchmarks.
