Intel Core 2 Duo E6300 & E6400: Tremendous Value Through Overclocking

Overclocking
Overclocking lower end CPUs is always more fun if you're actually buying these things because, as long as the manufacturing process is mature and your component selection is sound, you're usually able to reach much higher speeds than you paid for - an ever rewarding achievement. The Athlon 64 X2 CPUs have been fairly good overclockers, with the X2 3800+ usually able to run anywhere from 4600+ speeds (2.4GHz) up to FX-62 speeds (2.8GHz) and sometimes slightly beyond (3.0 - 3.1GHz). While we don't have any Socket-AM2 Athlon 64 X2 3800+ CPUs on hand (we will use a 4600+ and underclock it for our benchmarks), we do have performance results of the X2 4200+, 4600+ and FX-62 to give you an idea of where an overclocked X2 3800+ can get you performance-wise.
What we didn't know previously however was how far we could overclock retail E6300/E6400 CPUs, and furthermore we had no idea what a highly overclocked 2MB Core 2 Duo CPU would perform like. Armed with two B1 stepping Core 2 Duo CPUs, one E6300 and one E6400, we went to task on overclocking them. Our goal wasn't to reach the absolute highest overclocks using high end cooling, but rather the maximum stable overclocks easily attainable with a stock Intel heatsink/fan. Undoubtedly we could have reached higher frequencies with more elaborate cooling, but we were more interested in the bare minimum of what was attainable - and we weren't disappointed.
Our E6300 was able to reach 2.592GHz using a 370MHz FSB at 1.400V (up from 1.320V stock):
Our E6400 was a bit more successful, reaching 2.88GHz using a 360MHz FSB at 1.350V (up from 1.300V stock):
Both CPUs were totally stable when overclocked and were able to complete our multiple days of benchmarking without behaving any less stable than when clocked at their default frequencies.

Damn, Intel must have lost my address. ;-)

This is just so sad, how far AMD fanboys will go. I really wish there was moderation allowed, here the user point system is hardly effective enough.JarredWalton - Wednesday, July 26, 2006 - link
I'm pretty sure that was sarcasm, Coldpower. LOL :)coldpower27 - Wednesday, July 26, 2006 - link
Well, I guess my bad, though without a /sarcasm tag it's hard to tell. This is n't real life where you can here the tone of people's voices. :PSunrise089 - Wednesday, July 26, 2006 - link
You were unable to tell "the Magic Money Fairy" was sarcasm?Why not just come clean and admit that you didn't read carefully.
coldpower27 - Wednesday, July 26, 2006 - link
I read plenty carefully, thanks.Sunrise089 - Thursday, July 27, 2006 - link
Seriously?You were seriously unable to tell the following was sarcasm:
"...you all get weekly checks from Intel"
"...most Intel processors really don't even work at all"
"...Intel pays off the companies to say they're Intel Inside"
and of course
"the Magic Money Fairy."?
Dude, it's understandable that you were reading fast and thought the post was fanboy-ism, which there is indeed a lot of. Refusing to admit that and stating instead that the original (actually quite funny) post wasn't clear is insulting to that poster and frankly somewhat alarming.

Your taking this way to seriously, if I can't recognize without smiley faces or a tag that it is sarcasm, it's acceptable considering this is written language. I rely on the tone of the conversation, which is absent here.
There is nothing to admit. There continues to be alot of AMD fanboyism at this site, even reading carefully, it sometimes isn't a simple task to deduce what is sarcasm from the rest of the fanboy drivel.
I am not refusing to admit anything, the poster should have considered this before he made the post, that not everyone will be able to catch the sarcasm, I assume the poster would have thought about this, and I already said my bad in the above post. You may think the establish indicators are sufficient for you, for me they are not.
Not everyone can percieve exactly the same things you can allright, and assuming otherwise is ridiculous in itself.

lol - was a bit of a knee-jerk response, I thought the same thing until I read all the replies before, and then realised that it was indeed (hopefully!) sarcasm. You can't blame coldpower with the amount of rubbish being spouted by some users with how 'biased' this site is.VooDooAddict - Wednesday, July 26, 2006 - link
Nice to see you get your own article again from time to time, reminds me of when I started visiting AT.The following deals with the gaming performance question most people are asking. I understand that the true focus of the article is 2m Cache vs. 4m Cache and the Overclocking impact. E6600 is still at the top of my list for a powerful new SFF thanks to the article. Regardless the article has prompted the following:
(Maybe the following can be highlighted in a Budget/Midrange Gaming system buying guide...)
I think it's undeniably clear that the Core 2 Duo Chips offer the most headroom for future GPUs and should therefore be at the top of most gamers’ lists if they can afford it.
What I think some people may still find important is that with any of these amazing CPUs ... gaming is still GPU limited. It begs for the comparison of the E6300/E6400, the 3800/4200 X2, and 3500/3800 Single Cores. With a quality lower cost boards and single video cards like the 7950GX2 and 1900 XT. Do the lower end CPUs really limit gaming with a single card solution? I think the 7950 would also give a good showing as to if the new higher end and Dual Cores really needed for SLI, or if new new "low end" which used to be the high end are enough to keep that 7950 going. Most gamers I find at LANs still only run 1280x1024 without massive AA/AF simply due to the popularity of the cheep 17" and 19" sub 12ms LCDs. I also find a large number of gamers (who enjoy gaming but don't really spend much time enthusiastic about the hardware) don't ever turn on AA/AF.
I'm not saying you didn't state that most games are still GPU bound. You clearly tell gamers clearly in the article that it's probably best to buy the E6300 with a high-end video card then a E6600 and a mid range video card. I just think that it needs to be shown.
