A bit like our intro there's not a massive need to go into a huge amount of detail with what's going on with the testbed side of things. We've covered it a number of times already and if you haven't seen our previous coverage I recommend you jump back a page and check out some of it for further information.
With all the motherboard and CPUs listed above along with the overclocking results on all those said processors in our graphs starting from the next page, we'll just get into the overclocking side of things with our two Ivy Bridge processors we've got here today.
First we'll start off with the baby Ivy Bridge processor, the Core i5 3570k. Using a combination of BCLK adjustment and multiplier adjustment we ended up with a 105 BCLK and a 44x multiplier.
As you can see below that helped results in a 4.62GHz overclock which is a healthy 1200MHz over the stock clock. Thanks to the boost in BCLK we also saw the RAM speed move up to 1680MHz DDR.
As for the 3770k, that didn't want to play as nice on the BCLK side of things. No matter what we did we didn't have much luck at all moving the BCLK around. We got into Windows at one point using a 100.5 BCLK, but even then it didn't feel like it wanted to play nice. It seemed to be purely a CPU thing as well because the i5 3570k really didn't have an issue.
In the end, though we did end up with a slightly higher clock than the 3570k thanks to a 48x multiplier which as you can see above bought us in at 4.8GHz. These aren't huge overclocks, we've had our 2600k running at 5.2GHz and we wanted to ask around a bit to make sure we weren't doing anything wrong.
The general consensus is that Ivy Bridge just isn't as strong at overclocking at the moment when it comes to air cooling and basic water cooling setups. Pouring LN2 over the chips will help you get massive MHz, but at the moment, the current crop including the most recent versions aren't overclocking as strong.
Still if we've learnt one thing, *cough* Bulldozer *cough*, it's that MHz isn't everything. While our 3770k comes clocked 400MHz lower than our older 2600k, can the upcoming Ivy Bridge platform offer better efficiency at the clock rate? Well, there's really only one way to find out.
Let's get started!
