BIOS Functionality and Processor Overclocking
Oddly enough, the small Intel DH57JG is superior to its larger cousin, DH55TC, in terms of setup and overclocking functionality. Although these options are not as rich as on overclocker-friendly mainboards (for example, you cannot change the CPU voltage or adjust memory timings other than the main ones), they are quite sufficient for some overclocking. The following table lists the key features this mainboard offers:
Using these options, we managed to overclock our CPU to 3.4 GHz, which is a mere 100 MHz lower than what we had with other mainboards without increasing the CPU voltage. This difference can be explained by the lack of an option that would counteract a CPU voltage drop under load as well as by the harsher temperature conditions of the CPU on the Intel mainboard.
We also want to note something we encountered during our tests. The memory modules we used (OCZ DDR3 PC3-12800 Blade Series Low Voltage OCZ3B1600LV2GK) have a rated frequency of 1600 MHz with 6-6-6-24 timings and 1.65 V voltage. We could increase the voltage and change the timings but the mainboard would not start up at a CAS Latency value of 6. This is a drawback and we had to use higher timings which had been selected by the mainboard by default. On the other hand, we must acknowledge that the mainboard delivered somewhat higher performance than its opponents, and this seems to have been due to some memory optimizations. Perhaps this is why the timings cannot be set too low, yet the mainboard works fast. You will see exactly how fast it is in the next section of the review.
