Even though ASRock openly advertises the overclocking features of its motherboards, you should not forget that most of ASRock motherboards are still targeted towards the entry level markets. At its heart, ASrock maybe a division of ASUS, but it is by no means on overclocking brand.
Before beginning to overclock the ASRock AM2V890-VSTA motherboard, the CPU
clock multiplier was adjusted to 6x and the memory to run in DDR2-533 MHz
mode. these changes ensure that neither the processor nor memory will hold the
Starting from a motherboard clock speed of
200 MHz, the clock speed was increased in 2-5 MHz intervals. The
ASRock AM2V890-VSTA motherboard easily passed 220 MHz, but just as quickly topped out at around 230 MHz. We tried a few higher settings, but system stability was mediocre and thus unacceptable. The ASRock AM2V890-VSTA did not post the best overclock we've ever seen, but I suppose it's not too bad for a non-overclocking pedigree budget motherboard.
The ASRock BIOS:
The BIOS that ASRock employs with the AM2V890-VSTA motherboard is a bit different from the standard layout were mainly familiar with. The options are in different locations, but they are all there aside from extensive overclocking tweaks.
The AM2V890-VSTA motherboard clock frequency
can be adjusted between 200-300 MHz in 1 MHz increments. You can also
adjust the PCI Express and PCI frequencies. It's a good idea to leave those at
stock speeds. ASRock includes multiplier controls, and you can raise the CPU voltage
slightly as well. In the case of the Athlon64 FX-62 processor PCSTATS uses for testing that
translated into a maximum of 1.45V.
In the same menu you'll find a comprehensive list of memory options. From CAS Latency to RAS-to-CAS
Delay, Burst Length and more, they're all there. Advanced memory timings are somewhat unnecessary
with a budget minded motherboard such as the AM2V890-VSTA, so we'd suggest
you just leave them alone.
DDR2 memory voltage can be set from 'Normal' to 'Ultra High', whatever that means. Several basic peripheral adjustments
can also be set. Now it's time to benchmark this
