Intel Core i7 Overclocking - A HotHardware How-To

8 thumbs up





Synopsis:  Intel's Core i7 processor offers a significant performance increase over previous generation Core 2 processors.  In addition, like the legacy Core 2 architecture, the new Core i7 also has a bunch more headroom for wringing upside performance out of the chip, maximizing value, power and return on your investment with overclocking.  In fact, Intel actually built-in a predefined overclocking feature called "Turbo Mode".  We explain how not only Core i7 Turbo Mode works but also how to manually overclock the Core i7 in the BIOS as well as give you strategies on maintaining stability of the system as you ramp up the Core i7 core frequency for even larger gains in performance.

Test System and Equipment:
  In this video spotlight we're overclocking the Intel Core i7 processor on Digital Storm's 950Si custom Core i7 gaming system that utilizes EVGA's X58 3X SLI motherboard and Corsair Triple Channel DDR3 memory.  Be sure to check out the Digital Storm and EVGA articles for additional details and a full review of the platform we tested on, as well as our Core i7 launch article, if you'd like a refresher on the chip-level technology we were working with in this HotHardware How-To.

Awesome video! Yes

Nice Vid. I would love to get my hands on one of those i7s. They look like so much fun to overclock.

Nice video indeed... It seems that OC'ing has taken a turn from its old trided and true method... So with out a FSB how do you get your memory running in 1:1 or does that not matter so much with core i7?

Hey Der,

It definitely doesn't matter as much with the Core i7, since memory bandwidth is already pretty killer. However, 1:1 is there. I just had a it turned down to 1600. You can run all the way up to 2GHz+ if you want in some systems/motherboards but again, I don't think it's worth it stability-wise for the small performance upside.

Thanks dave,

So the Host frequency is inessence the "FSB" interms of figuring out the clock when using the multiplier then.

The PQI is confusing, if i understand it, all the cores can talk with one another and with the MCH?

very informative video. like dave keep it up! i wish you could do more videos like that for other products!

I wish I could watch it :-( I'm at work tho.

sweet video. Can't wait to get my case back and set up my WC so I can play around with it. I am sure I will have plenty to ask and talk about when that happens.

Same. I think I'll OC my 920 when I get home though. Only had it about a month, so I hadn't bothered with it yet, but this is a good reminder to do so. I was going to OC my GTX 280 too, but I think I'll not, and just do a step-up down the road a bit (EVGA).
