E6300's and E6400's to Officially Become Allendales?

[sanjiwatsuki]

Appearantly, recently, there are now L2 steppings and B2 steppings. The B2 being the Conroe cores with 2MB cache disabled and the L2 being the true Allendales.

The Allendale core seems to run cooler without those 2MB of useless cache, however, currently their overclocking ability is disputed.

The Conroe core is generally considered to be the superior overclocker, despite higher temps. Once again, there are no hard data backing this up. The only thing is that it is proven to be a solid OCer.

According to ripping.org, the E6300B2 seems to be the superior choice. The world record is a blistering 4442.74mhz compared to the L2's 3.5ghz.

On the flipside, despite being out for a VERY limited amount of time the E6400L2 has a WR of 4906.7mhz! This bested the B2's 4821.24mhz!

Granted, this speeds required vcores of upwards of 1.8, but it still shows that there is no concrete evidence showing one way or the other.

The E6400L2 seems to show off the potential of the cooler Allendale core, but the E6300 leaves much to be desired. Did they simply get an absurdly good chip or or it closer to the norm?

My take on the matter is that it seems there is relatively similar potential, except that the L2 has a lower temp, thusly allowing higher clocks. If all goes well, it shouldn't matter if you have an L2 or a B2, both hopefully will overclock well.

What do you think?

Allendale cores run at 200 mhz stock front side bus, while Conroe run at 266 hmz front side bus speed. With the quad pumping you get 800 mhz and 1066 mhz.

How do we tell the difference?

Not only a good place to shop, a good site to do some research. If you've got the processor installed, track down CPU-z. Good program to use. Very informative.

I don't have it installed. I'm in NZ so newegg is relatively useless.

Useless for buying things, yes, but that doesn't mean that specifications aren't.

While the specs are helpful, it still doesn't answer my question. How do I tell the difference between L2 and B2 when buying in NZ.

The term Allendale is supposed to refer to any chip that physically only has 2MB of L2 cache. The original E6300 and E6400 where actually rejected Conroe cores which didn't have their full 4MB cache working so were so with only have activated. Intel has since started producing true 2MB cache chips which are obviously cheaper. These Allendales are used for both the E4300 which has the 800MHz FSB and the E6300 and E6400.

On the flip side, the E6300 and E6400 are on the way out since they are to be replaced with the E6320 and E6420 in Q2 which operate at the same clock speeds but are true Conroes with the full 4MB of cache activated. Allendale will then be restricted to the E4xxx line and the Pentium E2xxx line which may or may not be launched.

Ah, that's what you were asking about. I feel stupid now, thought you were asking about something else.

Check the chip, I imagine. There was a thread about it not to long ago. But then again, use CPU-Z once you have the chip. Retailers and etailers generally don't have that on the site due to the volume they go through, and the mixture of chips they have.

Ta for that dude. Sorry about the misunderstanding. By the way, does it actually make any difference? I mean having spared deactivated chippery would probably only affect heat, wouldn't it?

 

[sanjiwatsuki]

That's what I'm wondering. Do neutered Conroe's outperform the Allendale by a large amount?

 

[dasickninja]

Not really. The only real reason "handicapped" Conroes beat true Allendales is because of the higher FSB.

 

[darious00777]

Didn't see that.

Makes fairly good sense. The core name seemed to be Allendale in some places, Conroe in others. Was thinking that the core names were based on stock front side bus speed.

Interesting. So it should be listed on the retailer's site then. Because I'd like to be able to tell if I'm buying a B2 or an L2
