This thread is to collect all stable overclocked Personal Computers with an Intel Micro-Processor.

The systems that are submitted to this thread have to be stable, or else they will not be added.

At least one of the following must be completed for the system to be defined stable, and screenshots of this must be shown to prove that it is indeed stable, 2 hours of stress testing is required using the applications as listed below:

• Prime95
• Orthos
• IntelBurnTest (please see additional info below)

Only these tests will be accepted, others can not be used unless previously agreed in the Discussion thread.

Note: You must run one instance of stress testing per CPU core (physical or virtual). This can be accomplished manually or through use of one of the newer software revisions that automatically tests all cores or through running multiple instances of the application and manually assigning affinity for each instance.

The following information must be stated when submitting a system:

• Processor model (e.g. Core 2 Duo E6600, Pentium 650, etc.)
• CPU clock speed (in GHz to the hundredth digit; e.g. 3.75GHz)
• Hyperthreading (on or off, for CPU's with HT capability only)
• CPU Bus/Bclk speed (e.g. 450MHz FSB, 200 Bclk, etc.)
• CPU multiplier setting (e.g. 9x, 20x, etc.)
• CPU core model (e.g. Conroe, Prescott, Yorkfield, etc.)
• CPU batch/stepping (e.g. Batch L629F, G0 revision, etc.)
• CPU voltage (as reported in CPU-Z; e.g. 1.45V, 1.344V)
• Motherboard model (e.g. DFI P35-T2RS, Asus Maximus Extreme, etc.)
• Cooling (please be specific, include fan setup if on air cooling, both CPU waterblock and radiator if on watercooling)
• RAM size/model (e.g. 8GB G.Skill PI DDR2-800)
• RAM speed (in DDR; e.g. DDR2-800, DDR3-1750, etc.)
• SuperPI result (1M) - Mod 1.5 validation version

Note: You must include a VALIDATED CPU-Z link in all submissions. This info also needs to be included in the same screen as the stress testing either as a separate window in the screen shot or having CPU-Z open once a validation has been processed (i.e. the validation number is shown in the lower left corner of the program) along with the stress testing window.

Note 2: When providing your screenshot, please show your stress testing application at 2 or more hours as well as task manager showing that all cores are at 100%. In the same screen, please show CPU-Z (for proof of voltage) and SuperPi 1M result. While not required, it is recommended that you attach the screenshot to your post instead of hosting it on another website.

Note 3: For IntelBurnTest users: Because IBT does not have a timer, it's recommended to set the test to run for a high number of passes (500+ for example) and after two hours has passed, stop the test manually.

Please refer to the Downloads section for stress test applications.

OK....I'll be the first to step up.

I ran prime running 2 sets of large fft's which doesn't test much memory, so i ran memtest along with it.

I have post my clock speeds and Prime 95 photo here

Hope it counts
Nice man....

you need to get a cpu-z validated screenshot of the overclock. Open cpu-z and go to the "about" tab and follow the steps to validate it then post the screenie.

Pshh..my cpu sucks lol

I'm running it on air ATM and it won't get stable over 4.2ghz no matter what voltage(embarrassing)

I'll post in here when I actually get a chip that doesn't have tempermental attitude problems

Please anyhelp will be great.
It's supposed to do that, when overclocking your CPU your memory will follow along since it is on the same bus.

I had to overclock my ram a bit to get it to 1:1 my Memory timeing 3-3-3-8 and thats as fast as i can take it to without hangups. but i still have low memory bandweith efficency.(bandweith efficency 47% )Why??? If you guys can help me with this then i`ll over clock it again and post the pic

Ahh come on guy's....u know i hate posting stuff like this..it make's some guy's feal bad,Im hear to help people reach high clock's and to show guy's the high end of computing...but i guess if the staff here need's me to post some pic's ill go grab some shot's and come back with them, Hold on to your panties boy's and girl's
