We tested: LGA6 motherboard with 7 types of 1155-series PCH

Test configurations, test conditions

We left everything in the system settings by default, the motherboard handled the components according to the factory configuration, except for one, the memories, which were manually set to 1 MHz using XMP profile 1866 with 9-11-9-27 CR2 timings.

The GIGABYTE B75M-D3V has only two DIMM slots, so instead of 8GB, 4GB of RAM worked in the config. Details of the settings are shown in the AIDA64 CPUID panel:

Of course, this time we performed the speed measurement related to memory management, usually with the help of AIDA64:

As well as the use of the AIDA64 storage module for storage management:

Tuning

Of course, boards equipped with the Z77 PCH could not be released without undergoing a quick tuning test. As soon as we started the overdrive (raising the Turbo Boost multipliers), we first increased the base voltage of the CPU to 1,35 V in the BIOS and pushed out the TDP limits. We then increased the multipliers either from the BIOS or using the Intel Extreme Tuning Utility. The increment lasted until the system was stable when running Fritz Chess Benchmark and wPrime 1024M (i.e., we did not test the settings to 100% stability, they are for guidance only). The result was documented by screen saver. As this was a simple, fast tuning mode, by no means professional, we did not experience any significant differences between the cards as expected, but rather the willingness of the Core i7-3770K ES was decisive.
