Overclocking and Performance
At first our overclocking experience with DFI LanParty JR X58-T3H6 was highly positive. First of all we made sure that with the CPU clock frequency multiplier reduced to 12 the board remains stable up until 215MHz base frequency. This is a very good result. It indicates that the board is theoretically capable of overclocking our CPU to its maximum and too high base frequency will not be a problem.
Then we managed to confirm system stability during CPU overclocking without any Vcore increase. Just like on most other mainboards we had tested before, we managed to overclock our processor to 181MHz base frequency. With the clock multiplier increased to 21 thanks to Turbo Boost technology, the resulting CPU frequency was 3.8GHz.
We didn’t increase the processor core voltage, because only in this case all Intel processor power saving technologies remain intact and working. When there is no serious load on the CPU, its multiplier and voltage will be lowered.
However, things were not so smooth anymore. First, you can see on the screenshot above that DFI LanParty JR X58-T3H6 does increase the processor Vcore under load. This increase is not as significant as we have just recently seen on Foxconn BloodRAGE mainboard, but nevertheless, it is noticeable enough, which is not good. However, the saddest thing is that we couldn’t raise the memory frequency to its maximum. It is normally possible to have the memory working at 1810MHz with CAS Latency reduced to 8 during overclocking when the base frequency is increased to 181MHz. This time the mainboard stopped at 1450MHz memory frequency although we still could lower the timings to 7-7-7-20-1T. Therefore, we couldn’t get the same testing conditions for the DFI and Asus boards, and logically, DFI’s defeat is no longer surprising.
However, we still have hope. During our overclocking experiments on Asus P6T we had to stop at 3.8GHz, while the little DFI LanParty JR X58-T3H6 kept going and let us raise the CPU frequency to 3.9GHz.
Although, in this case we had to increase the CPU core voltage, which affected Intel CPU power-saving technologies. In idle mode the clock multiplier did go down, but the CPU core voltage didn’t. The two screenshots above show different voltages not because the power-saving technologies kicked in, but because DFI LanParty JR X58-T3H6 mainboard increases the CPU Vcore under heavy load, as we have already mentioned before.
However, even in this case the memory on DFI LanParty JR X58-T3H6 worked at a lower frequency, so there was no convincing victory over Asus P6T.
