ASRock P45X3 Deluxe BIOS:

The motherboard BIOS is probably one of the most boring areas to look at if you're not an overclocker or enthusiast.  Mainstream users will probably want to skip down to the overclocking section to see how easy it is to tweak and overclock this board.  For you hardcore users, check out the BIOS screenshots of the 1.10 BIOS below.  During testing, ASRock released the 1.20 BIOS, but it didn't apply to our particular test setup so we stuck with the 1.10 BIOS.  Many sections like "Boot Order" have been left out as we simply can't handle that much excitement.  For now, the advanced bios settings will have to keep you happy - and tweaking your RAM, CPU and voltages until your heart's content.

As you can see below, the "SMART" features of the BIOS include multiple profiles that allow for simple overclocking or power savings.  Also the Instant Flash utility allows you to quickly, easily and safely flash your BIOS when the file is located on a flash drive, floppy or even a CD.  The Advanced settings will be covered a bit more as we go on.

The Advanced CPU Configuration shows off the CPU clock frequency setting as well as PCIe frequency.  CPU Frequency can be set anywhere from 100MHz to 800MHz while PCIe is adjustable between 50MHz to 150MHz.  Other features shown here are CPU Thermal throttling, Virtualization and more.  Chipset settings include memory speed that can be selected from DDR3-800, DDR3-1066 and DDR3-1333 by default.  If you choose manual overclocking mode, you can select up to DDR3-1600, but that will require you to run at 400MHz FSB in order to run your RAM at that speed.

Voltage adjustments are as follows:

  • CPU - 0.81875v to 2.0v in 0.00625v increments.
  • DRAM - 1.561v to 2.429v in 0.014v increments.
  • GTLRef - 0.615 x Vtt to 0.67 x Vtt in ~0.02 increments.
  • NB - 1.11v to 2.21v in 0.02v increments.
  • NB GTL Ref. - Auto, Low, Normal
  • SB Core - 1.536v to 1.8v in 0.009 increments.
  • SB 1.1v - 1.11v to 1.51v in 0.02v increments.
  • VTT - 1.21v to 1.91v in 0.02v increments.
  • PLL - 1.5v to 2.78v in 0.02v increments.

One of the nice features of this board is the ability to control fans based on temperatures as well as saving your BIOS tweaks to different profiles.  I've used the latter feature quite a bit as it allows me to select between a whole bunch of tweak settings without having to go through and figure you just what I was doing before I crashed something - which only happened once.

 

Overclocking:

This board was actually a pleasure to overclock and while we didn't break any records, you have to keep in mind that due to time constraints we didn't spend hours tweaking this board to perfection.  Out of the box, I was able to raise the FSB to 400MHz and get the CPU running at 3.6GHz at stock voltage.  My real concern though is how high we can run the bus speed as this is typically the limiting performance factor in LGA775 setups.

We did manage to boot and run a few benchmarks at 460MHz FSB x 8 = 3.68GHz, but we weren't rock stable until we backed the bus to 433MHz.  At this speed we were rock stable.

On the next page we'll start testing out the board and dive into the HDD, Audio and Network subsystems before we get into overall performance testing.
