Super Fast Like A Formula One Race Car

white Reviewed By: Dr Mark on 11/19/2008
Rating + 5
Tech Level Tech Level: high - Ownership: more than 1 year
Pros: The QX6850 is the fastest Intel Core 2 Extreme Quad Core Processor with the 65 nm Manufacturing Technology Process.
It is comparable to the newer 45 nm Processor QX9650, as both have 3.0GHz clock speeds with 1333MHz FSB's,
the only diference is the QX6850 has only an 8MB-(2x4MB) L2 Cache versus 12MB for QX9650.

I have been using mine since August, 2007 and could not be any happier when it comes to overall performance, either one you will not go wrong or be disappointed !!

Sorry Newegg but since then I have purchased and any future Purchases will be from Newegg #1 E-Tailer, You have lifetime Customer, Tahnks for your exemplary Service !!!
Cons: Unfortunatly I did not purchase this from Newegg in August 2007

Update on the beast

Tech Level Tech Level: high - Ownership: 1 month to 1 year
Pros: Sweet! very excited finally got it to run stable at 4.0!!! took a lot of resets and blue screens but the remedy was VOLTAGE! This is my first time really doing a lot of over clocking and now i know. CPUs love voltage. Running 1.6V at 333x12. unlocked multiplier is handy, probably could get lot higher on more extreme board. I am running on EVGA 750i . If you can afford DDR3 get the Striker boards or the new EVGA 790i Digital PWM, got all solid capacitors, should push some good numbers and is good idea if you want to do extreme overclocking.
Cons: nope
Other Thoughts: QX6850 @ 4.0Ghz!

If you have this thing make sure you overclock. 3.6 is no problem just max green voltage and change multiplier to 11. Anything higher than 3.6 requires more tweaking. Ran 1266 FSB with 13 multiplier for 3.8 which required nearly no voltage increase and 100% stable.

Oh and give your CPU 8Gb of ram!

Very Fast, Works like a Charm

Pros: Very fast CPU, especially after some good overclocking. Installed easily on my MSI P6N motherboard and booted with stock speeds without a problem. I am using an air cooler, the Xigmatek S1283, with a 120mm fan in my Antec P182 case. I overclocked to 3.4GHz and run about 35-40C on idle and up to about 65C on load. This thing can easily take the heat and you really should not start worrying about it until it gets over 75C. Makes everything you do so quick and simple. Opening Photoshop was sped up by at least 3 seconds, unzipping large documents is nearly instant, Xvid encodes at about 75-90 frames per second, it is amazing. For those wondering, this scores a 5.9 (the highest rating) on Windows Vista Experience Index, and therefor overclocking gets a 5.9 as well. Pretty amazing stuff. Stock heatsink is not good enough, I would not even try to use it. If nothing else, get the nice cheap Freezer 7 Pro.
Cons: None at all. I would not pay retail price for it, but if you can get it through something like Intel's Retail Edge, go for it!
Other Thoughts: Intel Core 2 Quad Extreme QX6850 @ 3.4GHz, Xigmatek S1283 CPU Heatsink, 8GB DDR2 RAM, MSI P6N SLi mobo, nVidia 9600 GSO, Antec P182 Case
