The Inquirer managed to get a 965 engineering sample to a core clock rate of up to 4GHz with fan cooling and Turbo Booster, this is quite impressive but may not be reachable on all home systems. IT OC Taiwan overclocked an engineering sample of the 965, to 4.20 GHz with a QPI rate of 200 MHz and a multiplier value of 21.0x. A vCore setting of 1.72V was used, which is far higher than the stock voltage of 1.25V and could lead to damage to the cpu or motherboard. A Core i7 940 system running at stock clock rates has obtained a 3DMark Vantage benchmark CPU score of 17,966.A Core i7 920 system scored 16,294 running at stock clock rates. An Intel Core 2 Extreme QX9770, a very expensive member of the previous generation of Intel processors (costing over four times the price of the 920 at its launch), scored 13,182 also running at stock clock rates.AnandTech tested the Intel QuickPath Interconnect (4.8 GT/s version) and found the copy bandwidth using triple-channel 1066 MHz DDR3 was 12.0 GB/s. A 3.0 GHz Core 2 Quad system using dual-channel 1066 MHz DDR3 achieved 6.9 GB/s.[20] Maximum PC has discovered that Intel has unlocked the clock and memory multipliers on retail 920s and 940s. This is allegedly due to consumer feedback.Core i7-975 will have the new D0 Stepping. Tests made by X-bit labs shows that it has better energy efficiency and overclockability than C0 stepping.
