Core i7 Overclocking Report
Well I had a chance to play with an engineering sample Core i7 with a Gigabyte EX58-EXTREME motherboard and 12GB of Aeneon DDR3-1333 C8 memory for an upcoming NCIX Tech Tips, and I’m actually very impressed with the platform.
I’ve mellowed out in the last couple years going from balls to the walls overclocking (think E6600 @ 4.0GHz 24/7 with a custom -25C chiller under my tower) to being more concerned with overall platform stability and maturity (while also loving speed).
On another note, I have a confession to make. My name is Linus and I have a memory addiction. I don’t need lots of memory. Frequently with 8GB in my system I was looking at up to 7GB of “cached” memory under Vista only being used to store frequently used programs. That didn’t stop me from salivating when I saw that high end X58 motherboards were going to feature 6 RAM slots. Naturally the first thing I did was load each slot up with 2GB of RAM.
Here’s a shot of the test bench I used including the less-than-stellar stock heatsink from Intel (got an APOGEE GTZ hold down en route from Swiftech), a 6800GT that has served me well over the years, and my ghetto sleeved OCZ GameXSTream 600W (also present in the top picture with my chiller). I will be doing a complete overclocking walk through for Nehalem on NCIX Tech Tips, but I wanted to share my initial impressions with a dog CPU, all 6 RAM slots loaded up (far more stress on the memory controller), and terrible stock cooling:
- 200x base clock multiplier without much fuss
- 1480MHz C8 @ 1.66V on this random set of 3 dual channel kits of memory primed for 12 passes overnight.
- QPI speed of over 1700Mhz without much trouble
- 3.7GHz on the CPU before running into what I think was a combination of a thermal limitation (80+C under load) and having a less than steller overclocking chip
