The Core i7 980X Review: Intel's First 6-Core Desktop CPU

Overclocking - Updated!
With six cores and 12MB of L3 cache on a relatively new 32nm process, it's not surprising that we weren't able to push our Core i7 980X too far. At stock voltage I was only able to reach 3.5GHz with turbo mode disabled using the stock cooler. I could get the system into Windows at ~3.7GHz, but not stable without additional voltage.
3.5GHz - Max overclock with stock cooling and stock voltage
Giving the chip extra voltage let me go up to 4.13GHz without sacrificing stability.
4.13GHz - Max overclock with stock cooling at 1.359V

how are you getting your productivity numbers/percentages ???Anand Lal Shimpi - Thursday, March 11, 2010 - link
Also note that I limited my voltage to a ~15% increase. I believe with more voltage it's possible to go higher, but you really start driving power consumption up at that point.Take care,
Anand

I saw on tweakers.net they were able to run it 3.45GHz on 1V and on 4.26GHz on 1.38V (or 1.33V can't tell that well due to the image size), without even trying hard. So are sure that it's the CPU that's limiting the OC and not something else eg the motherboard?Bolas - Thursday, March 11, 2010 - link
How does this cpu compare to the 6-core 32nm Xeon server chips that are launching around the same time? Any cost information on those yet? I mention this because I'm seriously considering EVGA's new dual socket W555 motherboard, which requires the dual QPI cpu's.goinginstyle - Thursday, March 11, 2010 - link
Is Intel offering 18 months no interest no payment plans for this? I really want one but I also want to eat and live in something besides a box for the next six months. Good article and nice to know the X58 boards we already have should work with nothing more than a BIOS upgrade.JonnyDough - Thursday, March 11, 2010 - link
This processor isn't for you then.It's for people who have nothing better to blow money on AND have money.

This is mostly a paper launch since few people will pay $1k for a CPU. As has been said so many times in the CPU/OC forums, keep your eyes out for the 32nm Xeon quads that will be appearing for LGA1366. They won't be 920 d0 cheap but they will be cheaper than the 980 and probably OC pretty well.erwos - Thursday, March 11, 2010 - link
If it's in the channel, it's not a paper launch. Period, end of story. Just because you can't afford it doesn't mean others can't.DrMrLordX - Friday, March 12, 2010 - link
It's not that it's unaffordable . . . it's just that I'm not that crazy. Close, but not quite.JumpingJack - Friday, March 12, 2010 - link
Maybe a career change that pays more :) ... j/k.
