All performance tests were run on the following test platform:
- Asus Sabertooth P67 rev. 3.0 mainboard (LGA1155, Intel P67 Express rev. B3, BIOS version 1502);
- Intel Core i5-2500K CPU (3.3 GHz, Sandy Bridge, LGA1155);
- 2 x 2048 MB DDR3 SDRAM Patriot Extreme Performance Viper II Sector 5 Series PC3-16000, PVV34G2000LLKB (2000 MHz, 8-8-8-24 timings, 1.65 V voltage);
- MSI N570GTX-M2D12D5/OC graphics card (Nvidia GeForce GTX 570, GF110, 40 nm, 786/4200 MHz, 320-bit GDDR5 1280 MB);
- Kingston SSD Now V+ Series (SNVP325-S2, 128 GB);
- Cooling system:
- Scythe Mugen 2 Revision B (SCMG-2100) CPU cooler;
- Additional 80x80 mm fan for cooling of the area around the CPU socket during overclocking experiments;
- ARCTIC MX-2 thermal interface;
- CoolerMaster RealPower M850 PSU (RS-850-ESBA);
- Open testbed built using Antec Skeleton system case.
We used Microsoft Windows 7 Ultimate SP1 64 bit (Microsoft Windows, Version 6.1, Build 7601: Service Pack 1) operating system, Intel Chipset Software Installation Utility version 188.8.131.525, Nvidia GeForce/ION Driver 266.58 graphics card driver.
Operational and Overclocking Specifics
We didn’t have any problems during the system assembly on Asus Sabertooth P67 mainboard. There were no issues during the mainboard operation in nominal mode and even during overclocking. The Asus P8P67 Pro mainboard reviewed earlier also easily overclocked our CPU to 4.8 GHz, but it consistently refused to boot at 1600 MHz memory frequency, even though it still passed all stability tests after a reboot. As for Sabertooth P67, we didn’t experience any boot-up issues, even though we used the exact same memory modules in exactly the same operational mode.
In idle mode all processor power-saving technologies worked perfectly fine: the processor clock frequency multiplier as well as its core voltage was lowered as necessary.
Overclocking to 4.8 GHz is a very good result. Some of the previously reviewed mainboards could only go as far as 4.7 GHz with the same CPU.
