Pentium 3.6C Retail Box (real of fake)

[Puchiko]

I recently did a google search for a Intel Pentium 4 3.6C Socket 478 processor and came up with a few stores that claim to have these in stock. I've seen the Intel roadmap on this site and others and there is no mention of a 3.6C part. Are these real or is someone mislabeling there stock? I've contacted the sites to no reply.

Probably mislabeled prescotts. If they have 1MB cache, then they are prescotts.

 

[Duvie]

I don't know!!! The ocing by some with the 3.4c northwood chips getting to 3.8 on air makes me think they may have the 3.6c...Heck it can't be any hotter then the prescotts...

 

[Mloot]

It's a possibility. For example, alot of ppl don't know that Intel also made a few 3.0 P4's with the old 400mhz FSB. AFAIK, about the only place you can get them are from Powerleap.

On Intel site the last one is the 3.4C, which is already rare to find...

 

[Puchiko]

This is the actual store link to the item in question

http://www.amamax.com/inpe42ghzb8f1.html

The description says Socket 478 and 3.6C but as far as I know there is no 3.6E either availlable in socket 478.

Why not try it out and run CPU-Z?

 

[RichPLS]

Wow, so there is a 1mb cache .13micron woody.
That is a cross between regular P4 and the EE.
Actually, it would be a EE with half cache!
Awesome.

This wouldn't be the first time a processor didn't appear in the processor finder, example SL6GV or the infamous 1.6LV Xeon. I think it may appear now, but at the time it did not...

Doing a google search of the part number, that seems to be the only site that has any referance to it whatsoever. It is possible that some of them exist, but I've never heard of any. I would have to see the markings on the chip to be sure though. Anybody wanna buy me one?? There were some experimental Northwoods using 8 metal layers instead of 6, but afik, none of them made it to market..

 

[stevty2889]

I e-mailed them to see if this was a misprint, I'll let you know if I hear anything back.

To clarify if it has a L2 cache of 1mb it's most likely a prescott, but im not aware that they had a 3.6 for a 478 slot. The EE CPU's have a L3 cache, but prescotts and 478's have L1 and L2 I think.

That is correct. EE's (the Gallatin-based ones, which is based on Northwood's .13um) have the usual Northwood 512K of L2 cache and 2MB of L3 cache.

The Prescotts come with 1MB of L2 cache instead of 512KB on Northwood (and yet are still slower, clock-for-clock, because they have a longer pipeline).


If that is a 3.6 GHz socket 478 chip, I'd suspect a Prescott if anything at all, and if they say 1MB of cache, that would immediately strike me as to mean Prescott.

It makes sense that a few of them would be made, ie for a company like Dell that maybe didn't want them all anymore (since they would be transitioning to socket 775 anyways) and sold them off to a reseller for cheap.

 

[stevty2889]

It's listed under socket 478 with 512k cache ...they haven't responed to my e-mail yet

I also tried to check on this yesterday. (I live in Houston and their site says their offices are here.)
I gave them a call twice and while they have an automated answering system I could never reach a live person.

I'd be very wary of this. My BS meter is registering a solid 7/10

You better hurry either way with northwoods. They are disappearing everywhere. My Frys stopped carrying them over 6 weeks ago and even newegg.com has a very limited selection of the "C" part. Why bother with 3.6? I bet it's hella expensive when a 3.0 is virtually the same chip? I mean sure Intel likes to call them 3.0 and charge hundreds less but really they will usually make the same speed for a fraction of the cost. Even if you don't overclock, we are talking about 15% difference in speed for ~lotsmore% more money. Wasteful IMO.

First off its only $335

Second off there was never a 3.6C for skt 478. Sure you can get a 3.6E for 775 but 3.4 is the fastest they go for 478.
It would be like finding a place selling an AXP 3600+ or an A64 skt 754 at 2.6 GHZ -- not something you see everyday.

 

[stevty2889]

The place has an 8.93 rating on resellerratings.com, so it may be legit, but I still haven't heard back from them.

 

[AristoV300]

The highest CPU speed for the S478 that Intel makes is 3.4 in the Prescott, Northwood, and EE variety. Just look on there site for further proof. Link

 

[stevty2889]

As somebody else pointed out, just because it's not on the intel sight, doesn't mean it doesn't exist. I have a mobile 1.6ghz P4 SL6EX, and havn't been able to find it on the Intel sight.

 

[stevty2889]

Damn credit cards. I gave in and bought one to see if it's for real. I'll let you know when I get it.

 

[stevty2889]

I just found one other referance to the existance of a P4 3.6c. It appears to be a socket 478 prescott..

 

[Mloot]

Cool, I'll be interested to see what they send you. If it's not a 3.6C, will you be sending it back for a refund, on the ground that you didn't get what was advertised?

 

[piroroadkill]

Curious, let us know how it pans out..

 

[jiffylube1024]

This should be a good chip if it's legit (and it looks like it probably is).

If it's a real 3.6C (meaning chances are it was made at the very end of the line of Northwood's life) I would anticipate 3.8-4 GHz on air, which would be incredible for a Northwood.
