While most vendors would tell you that modifying the BIOS options on your system is a bad idea (and Alienware might say that too), the fact is that because they are using widely available components (like Foxxcon, eVGA, and BFG), BIOS accessibility is going to be much better on the Aurora 7500 than in Dell or HP computers, for example.
Here I’ll go through very quickly what the BIOS settings were set at from the factory, and see if there are any areas Alienware missed to tweak the system out a bit more.
The initial POST screen tells us that we are running at 800 MHz on our DDR2 memory and in 128-bit dual channel mode. All good so far! First issue though — the memory is running at 2T and SLI-memory features are disabled as well.
It looks like Alienware left the motherboards’ BIOS at mostly default settings, and in most cases this is more than adequate though. Here we see the system clocks menu including the reference clock, multiplier, PCIe bus speeds and HyperTransport speeds.
Voltages are alll set to Auto, as indicated by this BIOS page, though the end user has the option to play around with these settings.
In the memory configuration page, you’ll notice that the SLI-memory settings are actually enabled, but Alienware set it to CPU 0%, meaning no processor overclocking is allowed by the motherboard and to just get the optimal memory speeds and/or timings.
Here we have all the memory timings under one single menu; the only thing that might need adjustment is the Command Rate, set at 2 clocks right now. 1T might bring about better performance depending on your applications.
Finally, the system monitor section in the BIOS indicates appropriate voltages and temperatures from the processor and power supply.
