help me identify this CPU!

like the title says, i need your help identifying this CPU, looked all over the internet can't find the specs for it. thanx in advance! its a socket 478/479(laptop).

 

did you try typing in the serial numbers on google?

 

yes i did, nothing come up.

Well, its going to be hard to find specifics, its an Intel Engineering Sample processor.

What system was that in?
If you can put it back into the laptop, and read what the Bios says, or get a cpu-z screenshot of the cpu, then you can determine what it is.
Its most likely a core 2 duo or core duo processor.

K-TRON

 

^^^^

Are you sure looked???

 

Jez!!! Just google the numbers on it!

I found in 30 seconds!

 

Looks like an early Engineering sample of the Core 2 Duo, perhaps merom for Santa Rosa. By looking up the Intel part number of LF80537.

 

well can you post the link?

does it have the same exact numbers?

i searched on cpu world and the number LF80537 gives me this http://www.cpu-world.com/cgi-bin/IdentifyPart.pl but i don't know which one it is.

i don't have a laptop to test it in, i wouldn't post it here i had a laptop.

 

Got it!

I posted a response on the forum thread 72Hundred provided. Surprisingly fast answer from Gennadily.

 

thanx a lot D3X. do you know what model number it is, example:t2300?

 

Nice CPU. Is it good?


Want to sell it?

If so I'd be intrested if it works and the price is right.

 

yes i was going to sell it after the i found the specs! PM with your offer.

 

I believe that would be equivalent to T5500 but with 4MB cache similar to a T7200. There is no actual retail model with the same specs.

 

thanx. you and 72hundred got a rep from me right?

 

I need more proof before I consider buying it.

Please find out what it is and I will consider buying it.

If this is an "Engineering Sample" IMO it will be a huge task to install in my Dell E1405, if not impossible.

 

thats why i posted in here cause i can't find any specs on it!!

 

It should be compatible, engineering samples are exactly the same and often the undervoltage yields is better compared to the retail / oem models. As long as the CPU is functional it will work in your E1405.

 

If the engineering sample is so much better, why don't Intel just sell a retail version with the same Spec?!

 

Engineering samples are often made from poor yielding "pre-production" fabrications due to earlier core manufacturing samples. Often most cores are non-functional and for testing only. Those ones that do work are then labeled as engineering samples, and these are successful cores out of probably 200 wafers of the silicon fav. Successful cores are likely far superior cores that are either low voltage or high frequency, but due to the success rate the cost of producing these ES cores are very high.

So to answer your question, these more superior engineering samples are likely the 10-20% top tier processors of the silicon fab, and likely the T7500, T7700 and X7800 of the same fabrication respectively, they are just labeled and multiplier locked accordingly.

Of course you have to understand the manufacturing process of processors, and I wouldn't be able to describe it in full detail for you to understand. The best analogy I can think of is like baking cookies. The raw ingredients are mixed and produced with a "recipe" and baked at the same time as a "batch". How good they are is based on the taste(speed) and form(voltage), and those that got burnt or distorted are thrown out. Those that look the best and taste the best are chosen as the best "cookies" for the luxury cookie product lineup and then decorated, and those that don't look so good but good enough for eating would be then thrown into a different section and packaged accordingly. This is the binning system, Often the recipe is later tweaked and better products(yield) are made(steppings)..
