Overview
Last week i had the opportunity to play with some of the latest hardware in the PC Industry. I was given an engineering sample of Intel Core i5 665K ES cpu and a Nvidia 465GTX graphic card to play with. Due to my busy schedule, i was unable to provide full-length review on both the cpu and graphic card. So i decided to run some simple benchmarks targeted to OverClockers. As always, let the pictures do the talking.

UPDATE 17-07-2010
After looking at the benchmark scores i obtain were kinda slow, i sent a feedback to MSI Malaysia. And after discussing with their engineer in Taiwan, i was told that the official BIOS v1.1 used does not fully utilize Intel K-Model processors. Therefore i decided to use the Beta Bios for another round of re-bench. For this round of re-bench session, i tried out Super Pi 32M first on Windows XP SP3 environment followed by Everest Ultimate Cache and Memory Benchmak, 3DMark 06 and finally 3DMark Vantage on Windows 7 Ultimate 32bit environment.

Intel Core i5-665K Introduction
Recently Intel just released the K model processors with unlocked multiplier. Currently there are two LGA1156 models, Core i5-655K and Core i7-875K. No doubt that these K model processors are now the main interest in the OverClocking Community. OverClockers now do not need to spend large sum of money to purchase the Extreme Series processors to enjoy the fun of OverClocking an unlocked multiplier processor.

Intel Core i5-655K
i5-655K is relatively easy to OverClock. With the unlimited multiplier option, BLCK is no longer an issue to higher cpu clockspeed. As for this test, my intention is just to hit 5.0GHz clockspeed and it was done within minutes. As my main priority is not on the memory, the ram is kept at the rated speed for all of the benchmarks done.

MSI N465GTX Twin Frozr II
Since this is a OverClocking Test, i carried out the testing in a very simple methodology, stock-speed vs oc-speed. With the MSI Burner tool, i could adjust the Core Voltage. Therefore, i set a core voltage limit to obtain the highest core and memory speed of the card. The core voltage was set to 1075mV while CPU is set to 4.0GHz clockspeed.

Conclusion
Intel i5-655K: It's yearning for Extreme OverClocking.
Nvidia N465GTX: Price is very close to ATI 5850 but the performance is not.

Special mention to MSI, Corsair, Antec and Intel

wonder what is the temp

[Sanko]

for CPU 1.47v for validation it's around 40 degree if i remember correctly.
