One of the reasons is that its an unlocked chip. You can overclock this to whatever specs you want, and it will not complain. Of course, the trick is to get the overclock USABLE and STABLE. That requires some thought and knowledge.. or a motherboard that has built in overclock profiles like the Asus Workstation Pro series of motherboards. Plus, it requires a GOOD COOLER.
This chip runs HOT. Its "failure temperature" is reported to be 212F / 100C, but I would be more conservative and say that if you start hitting 70C on this chip you need to re-evaluate your cooling. Another thing to note - the cooler that comes with the chip? TRASH. Well, let me qualify that statement a bit. The stock cooler *WILL* cool this chip to usable temperatures, if a) you do not overclock it at all b) have a very good airflow system and c) do not intend to do anything really heavy.
The last part there - "do not intend on doing anything really heavy" rather defeats the purpose of having a quadcore. You can surf and write documents on a Pentium M chip if that's all you need to do. This chip is meant to WORK, and WORK HARD. So, with that in mind, the stock cooler is not to be considered when you buy this chip. You HAVE to buy a better cooler and I would say it is also important (if not essential) to buy an aftermarket thermal paste like an Artic Silver or Arctic Cooling MX-1. Do not skimp on this, and it will reward you well.
For overlocking into 3.8ghz and upwards to 4GHZ you will need a very good water cooler.Read more ›

I have a Dell XPS 700 that I purchased in December of 2006. The original CPU was a Intel E6400 2.13GHz and achieved a respectable Windows Experience Index (WEI) of 5.1. Because the XPS 700 has a NVIDIA N590 chipset, I was able to "overclock" (OC) the E6400 to 2.66 GHz by flashing the BIOS to 1.4. and using the "N-Tune" utility from NVIDIA's website. The E6400 with the OC now has a WEI of 5.3. Note that N-Tune is an operating system (OS) utility and some games act abnormal in this mode. Examples are over talking or acting like they are on massive steroids. A nice work around is to use the command line "bcdedit /set useplatformclock TRUE". This will give the overclock benefit and cause the game programs to behave.
The XPS has (x2) GTX 550ti video cards. One is a PNY XLR8 and the other MSI Cyclone-II. The game bottleneck, even with the OC is the CPU, which is why I decided to upgrade.
In my research, I discovered that I could add a quad CPU up to a QX6800. It was an obscure statement on one of Dell's forums that went something like, unlike other XPS motherboards (MB), the H2C does NOT support the following…. and a list of CPUs followed. One enterprising user took a leap of faith and decided that the Dell tech meant that the XPS 700 would support the CPUs in the list and plopped one in and it worked. So, I decided to try.Read more ›
On my computer, I have a Gigabyte GA-P965-DS3 Motherboard (Version 1.0, Bios Version 13). With Intel's 965 chipset The Bios gives me a choice of multipliers for the QX6700 ranging from 6x to 16x. I have tested almost the entire range of multipliers and found through trial and error that the maximum usable range is between 6x and 11x with my current hardware configuration. outside the range of multipliers I specified above , my PC will either fail to boot, fail to load the OS (Windows XP) or fail to run applications in Windows causing the PC to reboot spontaneously, often without warning.
I have found my 'happy medium' configuration on my PC to be: OC the FSB from 266 MHz to: 333MHz, OC Memory from 800MHz to 833 MHz, CPU Bus speed multiplier:10x results in CPU Core OC from 2.66 GHz to:3.33.GHz; With these settings, my PC is about 95% stable, and never overheats as long as I clean the Case Air Filter, Fans and Heatsinks Monthly.
Note: The CPU Cooler I am using is a ThermalRight brand, Air Cooled unit with 8 Copper Heat Pipes transferring heat from the CPU to a 120mm W x 110mm H x 79mm D Aluminum Heatsink cooled with a 92mm SCYTHE KAMA PWM controlled variable speed fan rated at 200 RPM - 2500 RPM, 0 CFM - 55.55 CFM; Thermal Compound I used between the CPU and the CPU Cooler is: Arctic Silver 5 Thermal Compound; I highly recommend the use of Arctic Silver 5 Thermal compound for any heat sink application.
I am very happy with the Intel QX6700 Extreme Quad Core CPU I installed in my PC.
