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.

Unfortunately, this article goes on the assumption that the AMD chips are not overclocked. To say that the low-end intel chips offer overclocked performance that the AMD FX-62 cannot reach is absurd. With an unlocked multiplier, the FX can certainly stay above Core2's low end. The same could be said for Lower End X2's.... I'd like to see a review with them overclocked compared to Core2's at stock.... Especially since such CPUs on the 939 socket are mature and heavily supported by outstanding overclocking mobos....OcHungry - Wednesday, July 26, 2006 - link
Just be patient till advertizing budget is dried up.I wish AMD was more co-operative in paid per review market that has plagued "money buys" technology.net.

Dear OC-Sharikou,AMD would have that ability if it were not for that $2.5B loan they just signed and obviously keeping your blog up and running. I hope you are banned for these types of false and mis-leading statements. By the way, where are all of these Intel ads you keep harping about?

Advertising and Editorial are completely independent and separate at AnandTech, we have a 3rd party ad agency that handles all advertising and sales. The agency is completely independent from AnandTech, Inc.The OP's points were addressed by the poster above; this article was done after response to the last one asked for more information on the E6300 and E6400. The overclockability of 90nm X2 CPUs is fairly well known, and enough reference points exist within this article to compare overclocked X2 performance vs. E6300/E6400 overclocked performance.
Take care,
Anand

Actually I think the article is missleading(not on purpose). To compare a 370FSB OC CPU with a 200FSB on DEF is pointless. I would have OC'ed all at least 2 CPU's from both sides to see what's the best buy for an OC'er.Sorry for my poor english.

This article also assumes you actually read it. From the article:DigitalFreak - Wednesday, July 26, 2006 - link
