Asus P7H57D-V EVO Motherboard

BIOS & Overclocking

The P7H57D-V EVO's BIOS should be easy for most individuals to familiarise themselves with. Generally everything is where it should be and the names of parameters are generic enough for anyone migrating from another motherboard brand to understand.




Naturally we aren't all that interested about the first menu tab, so off we went to the Jumper Free configuration tab.


Overclocking on the LGA1156 platform isn't particularly difficult, where the main parameters include CPU BCLK (reference frequency), a CPU Multiplier and a Memory Ratio. Asus include a number of different Overclock modes. Auto, Manual, X.M.P and D.O.C.C. The first one enables Asus' own Auto Overclock utility, while the final two will adjust the CPU Multi/BCLK in order to attain memory speeds higher than the 1333MHz offered. For example, our 4GB Corsair PC3-12800 memory kit has an X.M.P profile to operate at 1600MHz with 8-8-8-24 1.65V parameters. Enabling XMP will fetch this data automatically.


As far as Voltage parameters are concerned, there's more than enough for those who overclock on air, water and possibly more “hardcore” solutions.




Our overclocking endeavours took us to a reasonable 198MHz max bootable BCLK before it would refuse to boot and a final verified stable frequency of 186MHz (a resultant CPU frequency of 4092MHz). I had personally hoped to see BCLK frequencies north of 200MHz with this particular motherboard however we didn't quite get there.





This isn't particularly related to the overclock itself, however we discovered that CPU-Z was reporting alarmingly high CAS Latencies of anywhere between 10 and 12. This would occur regardless of automatic SPD detection or manual selection of the parameter in BIOS. We came across a newer BIOS on the Asus website, which includes “improved memory compatibility”, which brings us on to...





Asus includes an embedded BIOS flash utility with a number of it's motherboards. Not only does it allow the user to update the motherboard's BIOS from a CD or Removable USB drive, it's also possible to access a ROM file from your Hard Drive. The tool permits navigation through your storage device's folders and will only display compatible file types.
