We chose the Core i5-750 for today’s benchmarks because it’s the most likely LGA 1156 processor to be paired with low-cost RAM.
Unfortunately, the retail i5-750 we purchased does not support the correct memory multiplier to reach DDR3-1600 at the processor’s stock base clock. For today’s test we were forced to use 160 MHz as the base clock for testing DDR3-1600 speeds, yet we were able to retain Intel’s super-tiny boxed cooler.

| Stability Test | Memtest86+ v1.70, single pass (~45 minutes) Max Speed at CAS 9 Min Latency at DDR3-1600, 1333, 1066 |
| Bandwidth Test | SiSoftware Sandra Version 2009.9.15.130 Bandwidth Benchmark |
CPU overclocking would have made anything more complex than a bandwidth benchmark unfair. We used Memtest86+ to verify stability at each memory kit’s highest speed and lowest latencies before obtaining those bandwidth numbers.
