The Bulldozer chip is old news...yes about 3 years now, right before Intel launched their i-series chips.
Overclocking in general - Hey kids, let's buy an expensive computer, then add a larger power supply and more fans, perhaps a water cooling setup,
then we can get the 3.2 processor up to 4.0 and have it run stable ...for about 6 months until the thing craters...
Hint for overclockers - You want a cpu that runs at 4.2 ghz? Then don't buy one that runs at 3.8 ghz and rearrange your life for that extra 400 mhz
I refer to my earlier post..
4 years of running at higher speed, no failure issues
I saved £55 by buying the mid range chip and only spent £10 on cooling. net saving of £45 ~ $75. with that I got a top notch graphics card instead of a mid range one for the same money.
Its not about getting the fastest speed possible, its just about taking off the ridiculously low limits that are imposed on most stock chips
come back to my place, I'll show you how to drink tequila.
So what was the difference in mhz? I overclocked an old pentium 1 chip and got a whopping 90-100 mhz, which in all honesty didn't do much.
My current processor in an i5 2500K Sandy Bridge which is pretty much made for overclocking....one guy got an extra 800 mhz, which to me would be an appreciable difference.
