Intel Core i5-750 Overclocking Preview

Our first preview of our Intel Core i5 processor that we purchased online last week. We put the 2.66GHz Core i5 model 750 through some overclocking paces to show you what can be achieved easily with an enthusiast air cooler.


Update: Make sure to check out HardOCP's Core i5 Performance Preview

So just how do we have this information for you here today considering that we are under a non-disclosure agreement with Intel when it comes to the new Core i5 processor? Well, you just go buy one online from Fry’s! That said, we have had a great relationship with Intel for a long time now, well, ever since that little Pentium III 1.13GHz recall thing we were involved in back in 2000. That did make for good news stories by Mike Magee way back when. Shifting back to today, we are making an effort to keep everyone happy, meaning HardOCP readers and Intel. Intel gives us great support here at HardOCP and we do not want to forsake the relationship built over the years. So, while this week we will take a couple of looks at Intel new Core i5, we will not be sharing any actual benchmark numbers till the official launch date and time which is next week. Today we will be sharing with you our overclocking experiences and tomorrow we should have a preview published showing you just how the Core i5 weighs in against a Core i7, clock for clock.

Core i5 Overclocking Test Setup


We used our retail purchased Intel Core i5-750 from Fry’s shown here. This processor is rated at 2.66GHz and utilizes the new socket LGA 1156. Our processor is S-spec # SLBLC, with a product code of BX80605I5750, and batch # L926B439.


For this overclocking shown here today, we used MSI’s P55-GD80 motherboard which we previewed last week. Embedded below is that video which shows you the GD-80’s features.


Patriot Memory’s yet-to-be-released 2GHz spec DDR3 Viper memory was run up to 1680MHz as you will see. It was run at stock voltages of 1.65v.


For cooling we used Thermalright’s TRUE Copper air cooling unit with a 72 CFM fan, which might be considered somewhat extreme at first glance. Keep in mind that we do NOT have mounting brackets yet for this cooler, so it was simply setting on top of the processor. Since it was just setting on top, we did not want to introduce a fan being directly attached to the heatsink causing a lot of vibration, so we simply set the fan off to the side blowing across the fins. Hardly an ideal setup, but it worked rather well.


A BFG Tech GTX 280 was used for testing.
