does anyone know if the allendale core core2 duo chips, are actually conroe chips with disabled cache... or if they actually are a different die design all together with less cache.


its something i've been curious about and cant find the answer to.

Allendale is just 2MB, no VT, and I believe no EIST.
200/800MHz FSB too.

The E6300/6400 are Conroe's, with just half disabled.

so e6300/6400 are not the allendale core.

i keep hearing that those are allendalre core, and some are conroe, or is allendale not coming out until q4 (whcih i have also read in some places)

Besides the lower clock speed (it is 1.86GHz for Core 2 Duo E6300) and smaller L2 cache, there are no other differences between the youngest model of the new family and the top-of-the-line solutions including Core 2 Extreme. It boasts all the strengths of the Core microarchitecture based products:

* Dual-core design . The CPU combines two independent cores working in parallel within the same packaging. These cores work at the same clock speed and share 2MB L2 cache. They are connected to the chipset using the same Quad Pumped Bus working at 1066MHz frequency and featuring 8.5GB/s bandwidth.
* Intel Wide Dynamic Execution . Each of the two processor cores can process four instructions per clock cycle.
* Intel Smart Memory Access . The enhanced data prefetch mechanism allows to reduce the idling time of the processor execution pipeline.
* Intel Advanced Smart Cache . Intellectual L2 cache is shared between the two processor cores depending on their load at the given moment of time. Moreover, the shared L2 cache speeds up data transfer rate between the cores and reduces the front side bus workload, because no data needs to be transferred via the system memory any more.
* Intel Advanced Media Boost . The processor works faster with SSE3 instructions because it can perform the binary operations with 128-bit SSE registers within one clock cycle.
* Intel Virtualization Technology (Intel VT) . This virtualization technology allows modeling the work of several virtual platforms on a single hardware system.
* Intel Enhanced Memory 64 Technology (Intel EM64T) . The processor supports x86-64 extensions that allow addressing over 4GB of system RAM and support the work with 64-bit general purpose registers.
* Execute Disable Bit . The OS is protected against harmful spyware and viruses that use ?buffer overflow? error to gain control over the system.
* Lower heat dissipation and power consumption . Core 2 Duo processors are manufactured with the newest 65nm technological process. Thanks to their architecture and a number of power saving technologies they boast the typical heat dissipation of 65W.

Correct, Allendale will launch with the E4x00 Core 2 Duo's Q4 of this year.

That's gotta be wrong, Allendale is a butchered main stream part. All e6x00's have the same features

Allendale is a codename for Conroe-Based processors with only 2MB of L2 Cache (Conroe is with 4MB of L2), the models of Allendale are: E4200 (1.6GHz, 800MHz FSB QDR), E6200 (1.6GHz, 1066MHz FSB QDR), E6300 (1.86GHz, 1066MHz FSB QDR) and E6400 (2.13GHz, 1066MHz FSB QDR)

I would say it is probably both, as that is most logical. The malfunctioning Conroe dies plus a native smaller cache die with the cache physically removed.

what i'm basically asking is if it is the full 4mb die size chip with 2mb turned off.,. or if it is just a seperate die mask.


when the first athlon X2s came out the 4200 and 4600 were the same die as the 4400 and 4800 , but then later on they changed it to a completely new die that wasnt disabled but originally designed with less cache.

so i guess from what i'm hearing here is, the first bunch of them has disabled cache, and the later bunch will be a whole new seperate die with 2mb cache launching at the start of q4 ?

i am asking since, i figure it might be worthwhile to wait until a real 2mb mask is out, so i can get the cpu cheaper (i figure a price cut will happen when those come out)

That is by no means guranteed. The information we can give you right now is were not quite sure on that.

Ok, so please help me to decide since I have waited and waited for Conroe to come out and now I all I can afford from Dell is the XPS 410 with the E6400, just the second rung up in the Conroe offerings, is it worth it or not to get it? Would a Pentium D 930 be better?
I need to purchase soon, am running an old Pentium III with Wondonws 98 SE.
Please advise me. I'd be so appreciative.
It costs like $200 or more to go up to the 6600 or 6800. Am I not getting a great chip with the
6400? I was so excited about it all before I read your posts.
Thanks for any help. We'll use it mostly for making CD's, digital photos and
even tv viewing with a tv tuner. By the way, what stations will I get with a tv tuner, just networks?
Is the 6400 a Conroe or not?

Thanks again. Any help for this novice is greatly appreciated. You're all so smart.
Wish I knew as much.

You're buying far more CPU than you need (if you can get by with a PIII then you don't need a conroe) as it is. A single core CPU is all that's needed for that, a slow CPU at that. I'm using a XP 2500+ for it now, three or four generations out of date.

The 6400 is a conroe, it is a very powerful CPU, it's a great design, it's a waste of your money ;)

Thanks for the reply. But our outdated Pentium III is not what we need anymore.
We want the newer microarchitecture and we want to be able to use our camcorders,
make videos, do tons of digital photos and have a tv tuner.
We want to update enough that we don't have to do it for quite some time.
I was just concerned since they were talking on here about the 6300 Conroe being such a lower end that it is comparable to the Celeron from days of yore being such a lower end that it was not worth it.
Is the 6300 or 6400 such a lower end that it is not even a real Conroe?
Thanks again for any help on this. If I get a Dell with the stepped up 6600, the system will run me about $1900 as opposed to the 6300 running me about $1750.
Did not know if it was worth the difference? Any comments welcome.
You're all MUCH smarter than I. I do want the newer technology, however, so I'm gettin' a Conroe! Just have to decide which Conroe.
Also, we might get into some basic level gaming. My husband likes that kind of thing.

So does the E6300 have VT? And is the codename for the E6300 Allendale or Conroe? I keep hearing conflicting info...

Amen, somebody answer the guy, please. I was so excited about getting the new Conroe and now am hearing that it's not even worth it unless you can afford the 6600 at least.
Dang, just can't get ahead. I don't want some fake Conroe, equal to the Celeron
piece of crap. Bummer.

Yes, the E6300 and E6400 have VT. Yes, their codename is Allendale. And no, they are not a fake Conroe.

Sounds like you've been listening to Felixdekat in that other thread. :disgust: According to him everyone should be rich and able to afford the best Intel CPU, and if you can't afford it then save up for it. Of course he was saying that even with Prescotts, so that should tell you something. He has little connection with reality.

What is reality? Well, reality is that the $330 E6600 is not almost twice as fast as the $185 E6300, while costing almost twice as much. Also, MHz for MHz I IIRC it still performs as well (or better) than an A64 x2, so to call it "equal to the Celeron" is inaccurate at best. In the cosmic scale of things I think it is about 8x the performance of the Celeron. :evil: I jest, I jest. It's only about 3x the performance of the recent desktop Celerons.

And BTW, welcome to the forums.

yes Allendale CPUs are E6300/E6400/E6500.........yes there is an E6500 as well ;)

they are the same as Conroe but with 2MB L2 Cache instead of 4MB conroes have

They also run cooler and have the ability to reach higher FSB than Conroes

I'm runnning the E6300 CPU with Gigabyte DS3

just started testing today

here is my second boot at 450MHz FSB

3150Mhz on CPU..........stock Vcore 1.26-1.28v
RAM: 450MHz 4-4-4-12 2.2v G.Skill HZ

http://img116.imageshack.us/my.php?image=450mhz4441222vdimmdual32msuperpigh7.jpg




I've been testing a decent 24/7 speed and think this will do
3GHz with only 1.136v with 430MHz on memory 4-4-3-12 2.0v :)
